OVERARCHING BUSINESS DRIVERS
OPERATING
RESPONSIBLY
Shareholders, funders, regulators, employees,
communities, consumers and other
stakeholders expect companies to adhere to
responsible and ethical practices. This includes
providing safe working conditions and fair
labour practices for employees, operating in an
environmentally responsible manner, ensuring
the safe operation and governance of dams
and residue storage facilities, preparing for and
responding to climate-related risks and
opportunities, and contributing to global and
local sustainability initiatives.
Consumers, shareholders and funders are
increasingly interested in ESG factors when
making buying, investment and lending
decisions. For mining companies, among the
most prominent topics on the ESG agenda are
climate change preparedness and carbon
emissions reduction.
In response to the growing demand for
sustainable jewellery and the need for
traceability programmes, certain jewellery
manufacturers and retailers are insisting on
traceability and proof of provenance of
diamonds.
Refer to the Climate change report on page 51
and our Sustainability Report 2023 available at
www.gemdiamonds.com for more insight.
GEM DIAMONDS’ POSITION
We are committed to ethical business practices, and corporate governance is a core
component of our long-term sustainability and value creation. We regularly enhance
our workplace safety systems and processes to ensure that we achieve our goal of
zero harm.
The Group remains strongly committed to environmental sustainability, and Gem
Diamonds’ inclusion in the FTSE4Good Index recognises the high standards of ESG
practices we adhere to. We have adopted eight UN SDGs and the TCFD
recommendations, and our residue storage facility management practices are
aligned with the International Council on Mining and Metals’ (ICMM) Global Industry
Standard on Tailings Management (GISTM). Our 2022 and 2023 awards for sound
ESG practices and climate reporting are evidence of our leading position on
sustainability in climate change, water stewardship and health and safety, in
particular.
All our diamond exports comply with the Kimberley Process
1
. We are transparent and
protect the provenance of all our diamonds, and we participate in the Gemological
Institute of America’s (GIA) Diamond Origin programme. This gives consumers
information regarding the country of origin of their diamonds and the positive impact
the diamond mining industry has on the communities and countries in which we
operate.

SUSTAINABLE RETURNS
Generating sustainable returns for
shareholders while continuing to create value
for our other stakeholders will ensure our
future.
Refer to the CEO Review and the CFO
Review on pages 30 and 34 respectively for
more information on the Group’s financial
results and operational performance.
GEM DIAMONDS’ POSITION
2023 was a challenging year, mainly due to a downturn in the diamond market
resulting in a significant decrease in revenue. Another challenge was increased load
shedding, which impacted operating costs of the treatment plants by increasing the
reliance on diesel-powered generators. We right-sized Letšeng during 2023 in line
with operational requirements, insourced the mining activities in December,
implemented initiatives to ensure plant stabilisation to improve production volumes,
and rigorously interrogated capital expenditure.

MARKET DEMAND FOR
DIAMONDS
Market demand for diamonds will be shaped
by the traditional industry factors of
affordability, desirability, value chain efficiency,
and the buying experience. Diamond
affordability relies heavily on economic growth
and consumers’ disposable income.
Desirability is measured by the share of
diamond jewellery sales within total luxury
consumption, as well as cultural acceptance of
diamond jewellery gifting. The growing custom
of using diamonds in bridal jewellery in India
and China, the increased use of diamonds
across a wider range of luxury goods, and the
continued growth in the number of high-net-
worth individuals worldwide support increased
demand for polished diamonds.
GEM DIAMONDS’ POSITION
We sell the majority of our rough diamonds on tender and are subject to immediate
market forces. We also have agreements to sell diamonds directly to the contract
manufacturers for some of the world’s premium luxury brands.
Diamonds from Letšeng are at the top end of the market in terms of size, colour,
quality and price. High-net-worth customers for large high-quality polished diamonds
tend to be less affected by global economic turbulence, and historically the prices for
larger high-quality diamonds have been more resilient to short and medium-term
market pressures.
The diamond market was under significant pressure in 2023 due to a challenging
macro-economic environment and international conflicts which negatively impacted
rough and polished diamond prices.
The average price per carat achieved for Letšeng’s diamonds decreased by 24%
compared to 2022. Large diamond recoveries were relatively comparable (five
greater than 100 carat diamonds sold in 2023 compared to four in 2022, and 84
diamonds between 30 and 100 carats compared to 87 in 2022).
US$1 334 average price per carat achieved in 2023
(2022: US$1 755 per carat)
69% of revenue derived from diamonds greater than 10.8 carats in 2023
(2022: 69%)
DIAMOND SUPPLY
The supply of diamonds is inextricably linked
to the economics of diamond mining. In
extended periods of low rough diamond
prices, mines close, which reduces supply.
Established producers tend to maintain
stockpile inventory, primarily in lower-value
commercial diamonds, which they release into
the market as demand ticks up, resulting in a
slower price increase in the short term
following an increase in demand.
The popularity of lab-grown diamonds is
growing, but prices continue to decrease,
which has also resulted in factories closing
down. These diamonds sell at a significant
discount to natural diamonds and are not
considered as a replacement for natural
diamonds, but rather as another diamond look-
alike in the same category as cubic zirconias
and moissanite stones.
GEM DIAMONDS’ POSITION
Annual global rough diamond production is expected to steadily decrease to around
110 million carats by 2030, having peaked in 2017 at 151 million carats. Total global
rough diamond production is estimated at approximately 121 million carats in 2023.
The decrease is largely due to a combination of planned mine closures, COVID-19-
driven closures of marginal mines and suspension and slowdown of certain other
operations.
A primary focus is to reduce diamond damage in mining and treatment activities to
improve the recovery of large, high-value diamonds and thereby protect their value.
Manufacturing of lab-grown diamonds has increased exponentially (c. 1 million carats
in 2015 to a forecasted c. 20 million carats in 2024) and although these have gained
popularity due to their favourable price point, this has not impacted demand or
prices of large high-value diamonds at the premium end of the diamond market.

SOCIAL VALUE
The Letšeng mine, which is co-owned by the
Government of the Kingdom of Lesotho (30%),
is an important employer and makes a
substantial positive contribution to the
country’s socio-economic development.
Refer to our Sustainability Report 2023
available at www.gemdiamonds.com for more
insight into our social contribution.
GEM DIAMONDS’ POSITION
We acknowledge our privileged position as custodians of the natural resources in the
countries in which we operate and we strive to maintain mutually beneficial
relationships with our employees, contractors, communities, regulators, governments
and wider society. We develop and empower our people, and endeavour to make a
meaningful, sustainable contribution to the countries and communities in which we
operate. We engage the government, employees and communities in life of mine
communications to inform them about relevant aspects of our operations and the
expected economic lives of our mines.
The Group’s community investments are informed by engagements with the PACs to
identify needs such as access to tertiary education, basic infrastructure (roads,
bridges and water supply) and local business development to create long-term
sustainable employment opportunities independent of the mine.
Letšeng makes a significant contribution to the Lesotho economy through dividends,
royalties and tax contributions, and provides employment for 1 297 people (including
contractors). This number excludes casual workers who are regularly employed at
Letšeng on a short-term basis. The mine also provides procurement opportunities to
support the local economy and the broader population of Lesotho.

CHAIRPERSON’S STATEMENT
The Board steered the Group through another challenging
year in the face of the global cost-of-living crisis,
international conflicts and the resultant downturn in the
natural diamond market.
Dear shareholders,
On behalf of the Board of Directors, I am pleased to share with you the Gem Diamonds Annual Report and Accounts for 2023, which
outlines the Group’s performance over the past year and highlights some of our focus areas for the year ahead.
We entered 2023 with the ongoing Russian invasion of Ukraine and the cost-of-living crisis which saw global economies grappling with
accelerating inflation, rising interest rates and continued supply chain challenges. The slowdown of global economic growth in 2023 was
further impacted by the conflict in Gaza that began in October 2023, and in early 2024, the attacks launched by Yemen’s Houthi rebels
on cargo vessels in the Red Sea.
The diamond industry suffered in the face of these challenges. Demand and prices for rough and polished diamonds exhibited material
weakness and, as reported by some of the world’s major diamond producers, declined year-on-year by as much as 40% in certain
categories of diamonds.
The past four years, starting with the COVID-19 pandemic, have been difficult for our business, with the result that our workforce, their
families and the wider communities within which we operate have all had to adapt to the new economic environment. The resilience and
fortitude they have displayed has been inspiring and commendable.
At Letšeng, the impact of a wide array of operating costs rising at a rate markedly higher than inflation put enormous strain on the
business. In particular, the fact that Letšeng is reliant on South African grid electricity supplier Eskom, which is currently plagued with
poor operating performance leading to frequent load shedding, resulted in a sharp rise in our use of more expensive diesel-powered
generators. These higher input costs, combined with a 26% decrease in revenue due to lower diamond prices, led to EBITDA reducing
by 65% compared to 2022. Management moved swiftly to address these external challenges by tightening cost controls even further

The Board had to make
important decisions during

determine the longer-term
sustainability of the Letšeng
orebody and the
preservation of value for all
our stakeholders.

Chairperson
and by taking a range of tough decisions to align the organisational structure with the market conditions. The financial results are
discussed in the CFO Review on page 34 and the financial statements are available from page 118.
Letšeng performed well operationally, especially in the second half of the year, with ore throughput in the plants being steady and
consistent. The COO review on page 41 contains the full details of Letšeng’s operational performance during 2023.
The sale, closure and/or handover options for Ghaghoo continue to be actively managed while the site is being appropriately
maintained and safeguarded, and we will continue to support management through this process.
We are pleased to report that there were no major or significant environmental or social incidents reported at any of our operations
during the year.
GOVERNANCE MATTERS IN 2023
The Governance section from page 62 provides full details of all corporate governance matters relevant to the Group in 2023.
I can report that there were no changes to the makeup of the Board of Directors during 2023, and that the current governance structure
is aligned with the independence requirements of the UK Corporate Governance Code and is fully representative with respect to both
gender and minority groups.
The findings from the external Board evaluation concluded at the end of 2022 were reviewed. It is encouraging that the report was
complimentary of the functioning of the Board, offering only minor improvement opportunities which we implemented during 2023.
In line with past practice, Gem Diamonds was again able to derive 99% of the workforce at Letšeng from within Lesotho. Increasing
female representation in our workforce remains a priority, and we have implemented various initiatives in local communities and schools
to create awareness of the many possible careers that exist within the mining sector, and to promote Letšeng as an employer of choice
for women.
Shareholders will be aware that Matekane Mining Investment Company (Proprietary) Limited (MMIC) has held the contract to conduct
mining operations at the Letšeng mine since 2005. In October 2022, Mr Sam Matekane (the ultimate owner of MMIC) was elected as the
new Prime Minister of Lesotho. In order to avoid any potential conflicts of interest between Mr Matekane's political appointment and his
business with Letšeng, we concluded a mutually agreed early termination of the mining services agreement and all mining activities
were taken over by Letšeng. I would like to take this opportunity to thank both the Prime Minister and Letšeng's management for the
professionalism with which this important transition was undertaken.
The financial and operational details of this transaction are included in the CFO Review on page 34 and the COO Review on page 41.
THE BOARD’S PRIORITIES IN 2023
• Considering the way forward for the Letšeng orebody, including the finalisation of the 2024 Resource and Reserve Statement
• Overseeing the implementation of initiatives to improve the maturity of the Group’s organisational safety culture
• Overseeing the execution of the Group’s decarbonisation strategy and the completion of its TCFD adoption roadmap
• Advancing efforts to sell or exit the Ghaghoo mine in Botswana, which remains on care and maintenance
• Implementing the opportunities identified by the external Board evaluation concluded in 2022
• Considering external growth opportunities
IMPROVEMENT IN SAFETY PERFORMANCE AND CULTURE
We regard the safety and health of our employees as our single most important priority, and I am very pleased to report that in 2023
Letšeng reported its best All Injury Frequency Rate on record at 0.67. We would like to congratulate and thank Letšeng’s management
and workforce for this notable accomplishment. The Board would like to express its gratitude for the effort and commitment that was
applied to drive forward the various initiatives that were developed following the 24-hour stop-for-safety shutdown in June 2021. We
recognise that it requires relentless focus and close attention to detail to achieve these results. Despite this achievement we all
appreciate the need to remain constantly vigilant and alert to existing and new hazards and risks, and to continue to build a mature and
collaborative safety culture where employees and management actively look out for each other’s safety and health at all times.
The COO Review on page 41 contains full details of Letšeng’s safety performance during 2023.
THE FUTURE DEVELOPMENT OF LETŠENG
With the Letšeng open pit mine progressing deeper every year, the Board carefully considered the future development of Letšeng’s
orebodies during 2023. An underground study carried out during the year indicated that underground mining of the Satellite pipe is not
currently an economically viable option and we therefore continue with optimising open pit mining at Letšeng.
Following an in-depth resource development programme that involved extensive core resource drilling, pit surface mapping, 3D
modelling, and petrography, we have concluded our NI 43-101 Technical Report. The report contains Letšeng’s 2024 Resource and
Reserve Statement and will be published on the Group’s website at www.gemdiamonds.com.
Refer to the COO Review for more details on the underground study on page 44 and the 2024 Resource and Reserve Statement on
page 45.

DECARBONISATION STRATEGY
During 2023 we made notable progress on our decarbonisation strategy with the Group completing its three-year TCFD adoption
roadmap as planned. At the beginning of 2023, we also announced that our decarbonisation target would be a commitment to reduce
our Scope 1 and Scope 2 carbon emissions by 30% (as measured against our 2021 emissions) by 2030.
Our primary focus is now on identifying and implementing ways to reduce our energy usage and at the same time searching for ways to
lower our dependence on the unreliable and high-carbon grid electricity supplied by Eskom. We continue to actively investigate
alternative large-scale, long-term energy solutions that will not only underpin the sustainability of the business but also contribute to
offsetting the wider suite of climate change risks. The energy consumption of the Group in 2023 is detailed in the Climate change report
on page 51.
COMMUNITY AND GOVERNMENT ENGAGEMENT
The Lesotho Government is a significant shareholder in the Letšeng mine and we seek at all times to maintain sound and constructive
relationships with government departments and officials. Accordingly, I am very pleased that during the past year we were able work
constructively with the new government following the elections in Lesotho in late 2022. Honest communication with all stakeholders is
crucial, and has been particularly so during the political and economic challenges of recent years. Their ongoing support will be
tremendously important as we seek to steer Letšeng’s operations through the current period of challenging market conditions.
We consider all stakeholders’ concerns and inform them about our business and the broader political, social and operational
environment that we require in order to thrive. This dialogue is conducted through a range of stakeholder engagement forums which
meet regularly and which routinely pass details of the issues discussed to the Board for its consideration.
LOOKING TO THE FUTURE
At the time of writing, it would seem that many of the challenges we faced during 2023 will be evident again during the coming year –
a difficult economic environment with slow economic growth impeded by several international conflicts. The prospect of declining
inflation and early indications of a reduction in interest rates in major economies suggest a stabilisation of the global economy
towards the end of 2024. Until then, we will have to remain resilient through effective cost control and delivery of further operational
efficiencies.
We will define the future development pathway for the Letšeng orebody based on the 2024 Resource and Reserve Statement, and we
will communicate widely and consult as necessary with all relevant stakeholders.
Our exit from the Ghaghoo mine remains a priority, and negotiations are continuing with the Government of Botswana on closure,
handover and/or rehabilitation should a sale not be possible.
The Group’s revolving credit facilities are expiring at the end of 2024, and we will actively oversee the extension of these facilities with
the Group’s lenders.
We will stay abreast of developments in the diamond market and respond appropriately by selling Letšeng’s rough diamonds through
appropriate channels and available diamond centres in order to achieve the highest obtainable market prices.
APPRECIATION
On behalf of the Board, I would like to thank every single person who has contributed to the Group’s performance in 2023, especially
our executive and senior management for steering the Group through a very challenging year. We thank our employees, contractors,
community partners, the Government of the Kingdom of Lesotho and our shareholders for their ongoing support. I also wish to thank

OUR STAKEHOLDER RELATIONSHIPS
Proactive stakeholder engagement is a fundamental
principle of sustainability, and we believe that regular
engagement builds mutual trust and understanding.
STAKEHOLDER MANAGEMENT
Gem Diamonds’ sound stakeholder relationships, particularly with its workforce, regulators, communities and government partners, are
critical to our social licence to operate. These relationships are built through regular, transparent engagement, and provide relevant
insights for decision-making while supporting the Group’s long-term sustainability and unlocking our ability to meaningfully contribute
to the broader society.
The Board is accountable for stakeholder engagement, and any issues raised by stakeholders are regularly reviewed, clearly
understood, and underpin the work of the Board. Stakeholder input is considered in decision-making for strategy, sustainability,
remuneration, CSI and other relevant matters.
Our communication channels are detailed below:

STAKEHOLDER ENGAGEMENT
Shareholders
Our shareholders include institutional and private shareholders. The shareholders are the owners of the Group, and the Board is
ultimately accountable to them for performance. They offer a potential avenue for the funding of future expansion opportunities. Our
strategy aims to maximise shareholder value in a sustainable manner.
The Chairperson, Senior Independent Director and Executive Directors regularly interact with shareholders at requested meetings,
during roadshows to larger investors, and at the Annual General Meeting (AGM), which is attended by all Directors. The CFO is
responsible for the investor relations function and is supported by an independent investor relations consultancy. Feedback and
concerns from investors are considered at Board meetings.
Shareholder interests include:
• growth opportunities;
• sustainable returns and capital allocation;
• cash flow generation and balance sheet strength;
• ESG considerations including corporate governance and ethics, responsible environmental and social practices, as well as climate
change and residue storage facility (RSF) management; and
• fair executive remuneration practices.

Engagements post the AGM
At the Group AGM on 7 June 2023, the Board noted the proportion of the votes cast against Resolution 2 relating to the approval of the
2022 Directors’ Remuneration Report (Resolution 2 passed with 69.0% of participating shareholders voting in favour) and Resolution 12
referring to the authority of Directors to allot shares (Resolution 12 passed with 69.5% of participating shareholders voting in favour). In
accordance with Provision 4 of the UK Corporate Governance Code, the Company is required to engage with significant shareholders
who vote against resolutions.
The 2022 Directors' Remuneration Report described the implementation of the Remuneration Policy approved at the 2021 AGM. Prior
to finalising the 2021 Remuneration Policy, the Board consulted its largest shareholders, and adapted the Remuneration Policy to align
with shareholder feedback. However, the Board is aware that one significant shareholder has a structurally different view on how the
Remuneration Policy should be implemented, and this impacted their vote on Resolution 2 on the 2022 Directors' Remuneration Report
at the 2023 AGM.
The Board is also aware that this same significant shareholder has a policy of not supporting resolutions referring to the authority of
Directors to allot shares, and this shareholder also voted against Resolution 12. This resolution reflected UK-listed company market
practice and the Board considers the flexibility afforded by the authority to allot shares to be in the best interest of the Company.
The Board, through the CEO, engaged with this shareholder since the 2023 AGM to help ensure any continuing concerns are
understood and considered the feedback during the Board's Remuneration Committee's deliberations over the 2024 Remuneration
Policy that will be presented to shareholders for approval at the 2024 AGM. The significant shareholder has a standing position on
Resolution 12, and the Board will regularly consider its approach to this matter.
Majority interest in shares
On 13 February 2024, the Company was notified of the following major interests (at or above 3%) in the issued ordinary shares of the
Company in accordance with the Disclosure Guidance and Transparency Rules (DTR) 5:

C Elphick is interested in these ordinary shares by virtue of his interest as a potential beneficiary in a discretionary trust which has an indirect interest in these ordinary shares.
There were no further updates at the date of this report. Changes in major interests in the Company are updated on the Company’s
website periodically. The shareholder base comprises 139.7 million issued ordinary shares of US$0.01 each (excluding the 1.5 million
treasury shares held by Gem Diamonds). Institutional shareholders hold 99.6 million shares (71.3%) while private shareholders hold 40.1
million shares (28.7%).
Employees and contractors
Our employees and contractors are responsible for running our operations and delivering on our strategy. Operating in a remote region
in a small country with limited resources makes the retention and development of local skills a priority. Gem Diamonds aims to provide
regular communication to employees on all matters relevant to them and to facilitate platforms where employees can express their
needs. The well-being of employees is a priority, and a full-time counsellor was employed at Letšeng during 2023 to assist the workforce
with mental wellness.
Engagement with employees through daily informal interactions, the employee app LetšGem, the Employee Engagement Committee,
the Group’s website, the quarterly Letšeng newsletter and frequent pre-shift “toolbox” talks with smaller shift teams provide
opportunities to interact. Regular site visits to Letšeng are also undertaken by the Board and executives.
Mazvi Maharasoa, a non-Executive Director, is the Board’s representative with delegated responsibility to engage with the broader
workforce and provide direct feedback to the Board on key concerns raised. Mazvi chairs the Group-wide Employee Engagement
Committee that includes employee representatives from all companies in the Group. The Committee provides a platform for the Board
to effect two-way communication to ensure that the workforce’s voice is heard in the boardroom and that Board expectations can be
communicated to employees directly.
The Letšeng right-sizing process in 2023 was not brought to the Committee by employee representatives as an item for discussion, the
Board was interested in receiving feedback on employees’ experience of the process. With participation from the chairperson of the
Remuneration Committee, Mazvi led the discussion and received positive feedback from representatives. The view was that the process
was managed fairly, first and foremost with employee well-being in mind, and that employees were at all times kept informed on its
progress. No significant matters were raised by employees during any of the Committee engagements in 2023 that required action from
the Board.
Towards the end of 2023, MMIC initiated consultations with their employees ahead of the insourcing of the mining activities by Letšeng.
The process was managed appropriately within the local legal framework, and the inclusive approach was pivotal to the successful
conclusion of the transaction and transition.

Employee interests include:
• fair treatment and safe working conditions;
• competitive remuneration; and
• skills development and opportunities for advancement.
Bankers, insurers and funders
Banks and other funders allow the Group to invest in capital projects and expansion opportunities. Insurance providers allow us to
mitigate certain risk elements, and form part of the Group’s overall risk management strategy.
The finance department engages with bankers and funders on an ongoing basis regarding facilities, compliance with covenants, and
debt renegotiations. At each operation, the finance team regularly interacts with insurance brokers, with detailed engagement around
renewal anniversaries with oversight from Group risk management.
In December 2021, the Group-wide debt refinancing was successfully concluded with the renewal of the Group’s revolving credit
facilities for an amount of US$71.0 million for a three-year period. US$29.9 million of the facilities are sustainability-linked loans (SLLs)
where the margin and resultant interest rate will decrease if the Group meets certain carbon reduction and water conservation key
performance indicators (KPIs). These KPIs are aligned to the Group’s sustainability strategy. Refer to the CFO Review on page 38 for
more details.
The Group’s revolving credit facilities expire in December 2024, but the facility agreement contains a 24-month extension option subject
to lender credit approvals. The process to either extend or renew these facilities will commence in Q2 2024.
Providers of finance interests include:
• responsible management of the Group’s financial position to ensure commitments can be met as they fall due;
• maintaining required covenants;
• performance against sustainability and climate-related targets for the SLLs;
• ESG practices and regulatory compliance, including effective management of residue storage facilities; and
• transparency in reporting potential material matters in a timeous manner.
Refer to page 34 in the CFO Review for more details.
Project-affected communities (PACs)
We are committed to ensuring that our PACs benefit from our operations and we recognise that the strength of our relationships with
our PACs helps in safeguarding our social licence to operate.
We take a multi-level approach to stakeholder engagement, including monthly engagements with local community leaders, quarterly
meetings with residents of local villages, and regular forums with district-level stakeholders and leadership. Letšeng’s Community
Liaison Officer (CLO) engages with the surrounding communities, government officials and community-elected representatives.
PACs select their community representatives, who sit on the Corporate Social Responsibility Investment (CSRI) subcommittee of the
Letšeng Board, creating a direct link between communities’ needs and Board decision-making. In addition to regular community
engagement forums, a grievance mechanism is in place for PAC members to submit issues directly to mine management.
Social and environmental impact assessments (SEIAs) and community needs analyses identify the most pressing community needs and
concerns. They are conducted through consultation processes facilitated by independent external specialists. The needs and concerns
identified through these independent studies form the foundation of our corporate social investment (CSI) strategies and community
engagement plans.
Community needs and concerns include:
• basic infrastructure provision and local economic development;
• improved access to education, skills development and healthcare;
• regular engagement and updates regarding progress on community projects;
• responsible and safe mining;
• environmental and social practices;
• responsible tailings management and disaster response mechanisms;
• local employment opportunities; and
• operational support in response to climate-related impacts, such as extreme weather events.
In 2023, the Group procured US$1.6 million of goods from PACs located around Letšeng and US$34.2 million of goods from the broader
Mokhotlong region. From 2016 to 2023 the Group has invested US$4.8 million in needs-based and sustainable CSI initiatives. In 2023,
the Group invested US$0.4 million in CSI projects in small and medium enterprise development, education and basic infrastructure
provision.

Customers
Gem Diamonds’ sound customer relationships support demand for our unique diamonds and help to ensure that the very best prices
are achieved. We interact with customers regularly in the normal course of business and at tenders, and communicate through the
Company website and press releases. Customers can access our electronic tender platform, which is used to provide specific tender-
related information.
Customers care about:
• consistent availability of large, high-quality diamonds;
• regular and transparent tenders;
• transparency and traceability of the provenance of rough diamonds; and
• responsible environmental and social practices.
Eight large and four rough diamond tender viewings were held in Antwerp in 2023. We were able to rely on our loyal customer base for
support during the year while the diamond market was under significant pressure.
Suppliers and business partners
Suppliers and business partners provide the products and services we require to run our operations and achieve our strategic
objectives, and we therefore build strong relationships with core suppliers. We are very aware of the increased importance of ensuring
responsible business across supply chains, and recognise the significant impact that suppliers and business partners may have on our
reputation. To this end, we ensure that formal written contracts are in place, and that negotiations are undertaken applying the
principles of fairness, transparency and responsibility that drive the culture of our procurement supply chain.
Suppliers and business partners care about:
• fair payment terms;
• local procurement opportunities; and
• responsible environmental and social practices.
Refer to page 35 in the CFO Review for details on Letšeng’s insourcing of its mining activities.
Regulators and government
The Government of the Kingdom of Lesotho is a 30% shareholder in Letšeng. We respect and adhere to regulations in all countries in
which we operate and maintain good relationships with governments and regulators. Engagements with regulators are held as
appropriate. We interact with government regularly regarding operational challenges where support is required, regarding employment
and progress on community initiatives, and to support local and national development priorities.
Government and regulator priorities include:
• responsible environmental and social practices and the health and safety of employees;
• good governance and ethics;
• community relationships and investments;
• local employment and procurement; and
• contribution to Lesotho’s GDP through dividends, royalties and tax contributions.
We have continued to work well with the newly elected Lesotho Government following the national elections held in Lesotho in October
2022. In difficult years such as 2023, it is especially important to communicate in an open, honest and transparent manner with our
government partners, as we need their support in guiding the operations through tough times in order to ensure the delivery of
sustainable value for all stakeholders.

OUR STRATEGY
Our strategy aims to maximise stakeholder value in a
sustainable manner. It underpins the Group’s purpose,
vision and values, which affirm our commitment to creating
social value and serving as custodians of the natural
resources of the countries in which we operate.
The Group strategy is developed by the management team, led by the CEO, and presented to the Board for review and approval. The
strategy is reviewed each year against developments in regulations, governance requirements, current market conditions and the short,
medium and long-term economic and market outlook. Where necessary, the strategy is revised to adjust for any such developments.
Our three strategic priorities aim to deliver maximum value for all stakeholders:
Extracting Maximum Value from Our
Operations
Working Responsibly and Maintaining
Our Social Licence
Preparing for Our Future
2023 STRATEGY REVIEW
In November 2023, the Board and executive leadership reviewed the strategy against the backdrop of the current macro, industry and
operating conditions. The review also considered the effect of these on the diamond market, industry peers and the Group’s
operations. A number of potential opportunities to enhance shareholder value were assessed, including external growth opportunities,
diversification across assets, potential partnerships, and operating structures.
Our medium and long-term strategic objectives remain unchanged and the business models remain appropriate to achieve these
objectives. Our flexibility in adjusting tactics in the short to medium term contributes to protecting and preserving long-term
fundamentals and strategy.
The Group’s overarching business drivers are set out on page 8. We aim to effectively contain costs while recovering the highest-value
diamonds to sell for the best market prices. The short to medium-term priority remains maximising value from our Letšeng operation
through three main focus areas:
Optimising the current
operating model
The right-sizing of Letšeng to align with operational requirements was concluded in June 2023.
The mining activities were insourced effective 1 December 2023 along with other selected
activities, such as housekeeping and the operation of the recovery plant. We continue to
investigate and implement ways to contain costs, enhance operational efficiencies and
rigorously interrogate capital expenditure. All operational contracts will be reviewed for
absolute necessity.
External growth opportunities
The Group has been a single-asset operation for a number of years, and although Letšeng is the
highest dollar per carat kimberlite mine in the world, it has a finite life and the operating
environment is becoming more challenging as the pits deepen. It is essential for the Group to
explore external growth opportunities, in the form of either acquiring other diamond-producing
assets or diversifying into different commodities.
Independent power
generation
Investigating and implementing longer-term alternative energy solutions is a top priority for the
Group. These will not only support our decarbonisation strategy, but also alleviate our
dependency on Eskom and reliance on diesel-powered generators during load shedding.
The tables below further define our strategic objectives and link them to relevant KPIs and targets. Our 2023 performance against our
strategic objectives is included in the CEO Review on page 30, the CFO Review on page 34, and the COO Review on page 41.

RISK MANAGEMENT
HOW WE APPROACH RISK
The Group’s risk management framework, which is fully integrated with strategic and operational planning, aims to identify, manage and
respond to the Group’s risks and uncertainties. The framework combines top-down and bottom-up approaches with appropriate
governance and oversight.
Risk management framework
BOARD OF DIRECTORS
The Board is responsible for the overall approach to risk
management for the Group and provides stakeholders with
assurance that key risks are properly identified, assessed, mitigated
and monitored. The Board maintains a formal Group risk
management framework, assesses and approves the overall risk
appetite and tolerance, and formally evaluates the effectiveness of
the Group’s risk management and internal control processes. It
confirms that the process is appropriately aligned with the Group’s
strategy and performance objectives.
At the quarterly risk review meeting, the Board reviews the risk
register, assesses management’s scenarios and plans, interrogates
the most critical risks in detail, and challenges mitigating plans with
management.
Top-down approach –
the Board sets the risk
appetite and tolerances,
strategic objectives and
accountability for the
management of the
framework
AUDIT COMMITTEE
The Audit Committee monitors
the Group’s risk management
processes, reviews the status of
risk management, and reports to
the Board on a quarterly basis. It
is responsible for addressing the
corporate governance
requirements of risk
management.
SUSTAINABILITY COMMITTEE
The Sustainability Committee
provides assurance to the Board
that appropriate systems are in
place to identify and manage
health, safety, social,
environmental and climate
change-related risks. It monitors
the Group’s performance within
these categories and drives
proactive risk mitigation
strategies to secure safe and
responsible operations and our
social licence to operate in the
future.
MANAGEMENT
Management develops, implements, communicates and monitors
risk management processes and integrates them into the Group's
day-to-day activities. It identifies risks affecting the Group, including
internal and external, current and emerging risks. It implements
appropriate risk responses consistent with the Group’s risk appetite
and tolerance.
GROUP INTERNAL AUDIT
Group Internal Audit formally reviews the effectiveness of the
Group’s risk management processes. The outputs of risk
assessments are used to compile the strategic three-year rolling and
annual internal audit coverage plan and evaluate the effectiveness
of controls.
Bottom-up approach –
ensures a sound risk
management process and
establishes formal reporting
structures

Oversight
Governance
Responsibility
The Board is ultimately responsible and accountable for the Group’s risk management function. It is supported by its subcommittees
and senior management in overseeing the Group’s most relevant and significant current and emerging risks. These risks are actively
identified, assessed, prioritised, managed and mitigated as much as reasonably possible, as they could negatively impact the Group’s
ability to execute its strategy.
While the Group’s risk management framework focuses on risk identification and mitigation, many of the factors that give rise to these
risks also present opportunities. Gem Diamonds tracks these opportunities and incorporates them into the strategy where they
appropriately support the Group’s purpose.
The Board and its subcommittees have identified the following key strategic, operational and external risks, which have been set out in
no order of priority.
1. Variability in
cash
generation
Risk:
Marginal cash resources and
variability of cash flows could
negatively affect the Group’s ability
to effectively operate, repay debt
and fund capital projects, and
impacts strategic short and long-
term decision-making. The risk is
directly impacted by other principal
risks such as rough diamond
demand and prices, variability of the
resource, economic viability of
reserves and volatility of exchange
rate.
Risk response:
• Rigorous cost and capital discipline is
in place
• Funding facilities are in place to
manage variability in the short to
medium term
• Focus on cost discipline to achieve
greater operational efficiencies
• Ongoing drive for continuous
improvement to deliver operational
efficiencies
Strategic impact:
2. Diamond
resources and
reserves
Risk:
Letšeng’s low-grade orebodies
make the operation sensitive to
resource variability. Unexpected
variability in key resource/reserve
criteria, such as volume, tonnage,
grade and price, could significantly
impact mine planning, forecasting
and financial stability, both in the
short and medium term, and could
influence decisions regarding future
growth.
Risk response:
• Gathering geological evidence on
variations within the resource
(lithology, density, volume/tonnage,
grade, diamond population size and
value distribution), applying industry
best practice and engaging
independent experts to audit and
provide advice
• Optimised mine plan
• Ongoing pit mapping, petrography,
drilling and 3D modelling
• Grade control, bulk sampling, density
and moisture content measurements
(on-site and independent lab
verification), dilution control, stockpile
management, data management,
quality control and internal auditing of
production data (including geological,
processing, recovery and sales data)
• Managing the Diamond Accounting
System and Mineral Resource
Management (MRM) database, and
monitoring recovery data on a daily
and monthly basis, as well as per
export period, to follow trends in
diamond distributions, large stone
recovery frequencies and average
diamond prices per kimberlite domain
Strategic impact:
Strategic
report
Gem Diamonds Limited Annual Report and Accounts 2023

3. Rough
diamond
demand and
prices
Risk:
Numerous factors beyond our
control could affect the price and
demand for diamonds. These
factors include geopolitical tension,
macro-economic conditions, global
diamond production levels and
consumer trends. Medium to long-
term demand is forecast to outpace
supply, but short-term uncertainty
and liquidity constraints within the
diamond sector may negatively
impact rough diamond pricing.
Risk response:
• Monitoring market conditions and
trends
• Flexibility in sales processes and
utilisation of multiple sales and
marketing channels including
additional viewing opportunities
• Ability to enter into partnership
agreements to share in the upside of
polished diamonds
• Maintaining the integrity of the tender
process
Strategic impact:
4. Availability of
sustainable
and reliable
power supply
Risk:
Regular power interruptions (load
shedding by the South African
power utility, Eskom) compound the
need for and cost of self-generated
power and escalated diesel prices.
Unscheduled power interruptions
and poor quality of power supply
reduce the available processing
time and negatively influence the
reliability and stability of plant
equipment.
Risk response:
• Exploring solutions with the Lesotho
Electricity Company (LEC) for grid and/
or renewable power
• Assessing the potential to generate
renewable energy for own use
• Prioritisation of load and allocation of
power
• Identification and implementation of
consumption-reduction initiatives
Strategic impact:
5. Growth and
access to
capital
Risk:
The volatility of the Group's share
price and lack of growth
opportunities negatively impact the
Group's market capitalisation.
Constrained cash flows add
pressure on returns to shareholders.
The Group currently relies on a
single mine with a finite life for its
revenues, profits and cash flows.
Risk response:
The Group’s strategic objectives are to
drive share price growth through:
• Assessing mergers and acquisitions
and diversification opportunities
• Focusing on existing operations to
unlock further value through
rationalisation and efficiency
improvements
Strategic impact:
6. Workforce
Risk:
Achieving the Group’s objectives
and sustainable growth depend on
the ability to attract and retain
suitably qualified, experienced and
ethical employees. Gem Diamonds
operates in an environment and
industry where shortages in
experience and skills are prevalent.
Risk response:
• Human resource practices are
designed to identify skills shortages
and implement development
programmes and succession planning
for employees
• Remuneration practices and incentives
are in place to appropriately
remunerate and retain skills
• Training and coaching plans are in
place to address skills and experience
shortages

7. Information
Technology
(IT) and
Operational
Technology
(OT) systems,

cybersecurity
Risk:
The Group’s operations rely on
secure OT and IT systems to process
financial and operating data in its
information management systems. If
these systems are compromised,
there could be a material adverse
impact on the Group through a lack
of production and/or compromised
recovery parameters.
Risk response:
• Application of technical and process IT
controls and policies in line with
industry-accepted standards
• Appropriate back-up procedures,
firewalls and other appropriate security
applications in place
• Vulnerability assessments to define
gaps and devise corrective actions
Strategic impact:
8. Production
interruption
Risk:
Material mine and/or plant
shutdowns, pit closures or periods
of decreased production could arise
due to various events. These events
could lead to personal injury or
death, environmental impacts,
damage to infrastructure and delays
in mining and processing activities
and could result in financial losses
and possible legal liability.
Risk response:
• Robust business continuity plans are in
place to ensure limited delays due to
disruptions
• Appropriate levels of critical resources
(fuel, ore stockpiles, etc) are
maintained to mitigate the impact of
any production interruptions
• Appropriate insurance is maintained
Strategic impact:
9. Health, safety
and wellness
Risk:
The probability of a major health or
safety incident occurring is inherent
to mining operations. Such incidents
could impact the well-being of
employees, PACs, our licence to
operate, the Group’s reputation,
and compliance with our mining
lease agreement. The health and
safety of our people is critical to the
business.
Risk response:
• Appropriate health and safety policies
and practices and training and
awareness campaigns are in place
• Dam safety management framework
has been implemented in alignment
with the ICMM’s GISTM
• ISO 45001 accreditation is maintained
• A safety management and leadership
programme, visible felt leadership, and
detection and prevention strategies
have been developed and
implemented
• We continually assess the
organisational safety culture maturity
to address current and emerging
issues
Strategic impact:
10. Security of
product
Risk:
Theft is an inherent risk in the
diamond industry. The high-value
nature of the product at Letšeng
makes it susceptible to theft and
could result in significant losses that
would negatively affect revenue,
cash flows and strategic short and
long-term mine plan decision-
making.
Risk response:
• Zero tolerance of non-conformance to
diamond security policies and
regulations
• Advanced security access control and
surveillance system is in place.
• Monitoring of security process
effectiveness is performed by the
Executive Committee and the Board
• Appropriate diamond specie insurance
cover is in place

11. Social licence
to operate
Risk:
The Group's social licence to
operate is underpinned by the
support of its stakeholders,
particularly employees, regulators,
PACs and society. This support is an
outcome of the way the Group
manages issues such as ethics,
labour practices and sustainability in
our wider environment, as well as
our risk management and
engagement activities with
stakeholders.
Risk response:
• The implementation of an appropriate
CSI strategy based on a community
needs analysis that provides
infrastructure and access to education
and healthcare and supports local
economic development
• Adoption of relevant standards, best
practices and strategies
• Appropriate governance structures
across all levels of the Group, including
established Employee Engagement

change
Risk:
Climate change-related risks
(transitional and physical risks) are
recognised as top global risks and
investors are increasingly focused
on the management of these risks.
The uncertainty of potential carbon
taxes and the impact of climate
change present significant current
and future risks to the Group which,
if not identified and managed
responsibly, could negatively impact
the Group’s long-term operational
and financial resilience.
Risk response:
• TCFD recommendations adopted and
climate change strategy developed
• Adoption of a Group decarbonisation
strategy and 2030 target
• Governance and management
practices implemented to oversee the

EMERGING RISKS
The Group risk framework includes an assessment of emerging risks, which considers those risks that:
• are likely to materialise or impact over a longer timeframe than existing risks;
• do not have much reference from prior experience; and
• are likely to be assessed and monitored against vulnerability, velocity and preparedness when determining likelihood and impact.
The current emerging risks that are being monitored by the Group are:
• lab-grown diamonds attracting a larger market share;
• generational shifts in consumer preferences; and
• future workforce (automation, skills for the future, etc).

VIABILITY STATEMENT
The Board has assessed the viability of the Group over a period significantly longer than 12 months from the approval of the financial
statements, in accordance with the UK Corporate Governance Code. The Board considers three years from the financial year end to be
the most relevant period for consideration for this assessment, given the Group’s current position and the potential impact on the
Group’s viability of the principal risks documented on pages 21 to 26.
While the Group maintains a full business model, based predominantly on the life of mine plan for Letšeng, the Group’s annual business
and strategic planning process also uses a three-year time horizon. This process is led by the CEO and CFO and involves all relevant
functions including operations, sales and marketing, finance, treasury and risk. The Board participates in the annual review process
through structured Board meetings and annual strategy review sessions. A three-year period provides sufficient and realistic visibility in
the context of the industry, the environment in which the Group operates, and the current short-term mine plan, even though the life of
mine, the mining lease tenure and available estimated reserves exceed three years.
The business and strategic plan reflects the Board’s best estimate of the Group’s prospects. The Board evaluated several additional
scenarios to assess the potential impact on the Group by quantifying their financial impact and overlaying this on the detailed financial
forecasts in the plan.
The Board’s assessment of the Group’s viability focused on the critical principal risks categorised within the strategic, external and
operational risk types, together with the effectiveness of the potential mitigations that management reasonably believes would be
available to the Group over this period.
GROUP FACILITIES
The Group has access to US$71.0 million in RCFs when fully available. Of these RCFs, US$30.6 million was utilised at the end of the year.
The Group’s RCFs mature on 22 December 2024. The existing facility agreement includes an option to extend the facilities for a period
of 24 months (subject to lender approval). The Group may also decide to renew these facilities for a potentially longer period of 36
months. These facilities have been in place since 2011 and have been renewed on three previous occasions through expanding the
lender group and increasing the overall facility amount. In addition, there is a general banking facility of US$5.5 million with no set expiry
date, but which is reviewed annually by the lenders. This facility was fully available at the end of the year.
ROUGH DIAMOND MARKET
Demand and prices for rough and polished diamonds exhibited material weakness and declined year-on-year by as much as 40% in
certain categories of diamonds, as reported by some of the world’s major diamond producers. The offloading of large, high-value
polished diamonds by other producers has had a detrimental effect on the top end of the diamond market. All of these factors placed
severe pressure on rough and polished diamond prices during 2023.
RISING COSTS
At Letšeng, the impact of a wide array of operating costs rising at a rate markedly higher than inflation put strain on the business. In
particular, the fact that Letšeng is reliant upon South African grid electricity supplier Eskom, which is currently plagued with poor
operating performance leading to frequent load shedding, resulted in a rise in the use of more expensive diesel-powered generators.
The price of diesel also remains high which has a direct impact on costs due to the large volumes of diesel used in the loading and
hauling of ore and waste tonnes. The Group strives to mitigate these rising costs through stringent cost control and efficient mining,
evidenced through the recent right-sizing and insourcing initiatives.
CLIMATE CHANGE
The Board is cognisant of the risks presented by climate change and conscious of the need to minimise carbon emissions. A Group-
specific climate change scenario analysis has been conducted whereby the short to medium and longer-term physical risks were
assessed. The short to medium-term impacts fall within the viability period. The physical risks identified for Letšeng, such as drought,
strong winds, extreme precipitation and cold, are similar to its current operating conditions. The operation is therefore well geared to
manage these conditions within its current and medium-term operational activities, cost structure and business planning. Additional
cash investment required in the event of these short to medium-term physical risks materialising has been assessed as low with no
material impact on the current operations and viability of the Group.
In terms of transitional risks, as users of grid-supplied and fossil fuel energy, the short-term focus is on improving energy efficiencies in
our operational processes and reducing the use of fossil fuels. Options are being assessed in the context of the size, nature and location
of the Group’s operations, the required investment and the expectations of our main stakeholders. Any material investment during the
viability period is considered unlikely. Due to uncertainty around the cost and timing of implementation of carbon-related taxes, the
impact of such taxes on the Group’s operations and cash flows has been excluded from the viability assessment and scenario stress
testing. Management and the Board will continue to assess these impacts as the information becomes more certain. The Group has
adopted a carbon-pricing model that will be used to responsibly assess the potential financial impact of future projects. The Group has
also adopted a decarbonisation strategy that is aimed at reducing potential future carbon tax liabilities.

CONCLUSION
The Group ended the year in a net debt
1
position of US$21.3 million and undrawn available credit facilities of US$45.9 million. These
facilities expire on 22 December 2024 and have an option to extend the facilities for a period of 24 months (subject to lender approval).
The Group will follow all necessary processes to extend the facilities for this available period or renew the facilities for an extended
period, as has been the practice in the past.
During the final year of the viability period, in 2026, there will be no Satellite pipe ore available for processing which will negatively
impact overall revenue and cashflows and access to RCFs will be required. It is estimated, based on the current life of mine plan, that
the availability of this higher-value ore will resume in 2030.
Letšeng, the Group’s core asset, is cash generative over the viability period and remains flexible in being able to adjust its operating
plans within the normal course of business. In the unlikely event that the RCFs are not renewed further cost-reduction initiatives could
be implemented during the viability period, and ongoing optimisation of the mine plan (as mentioned in the COO Review on page 48)
may further reduce the cost profile in the period. Based on the robust assessment of the principal risks, prospects and viability of the
Group, and the successful extension of the facilities, the Board confirms that it has a reasonable expectation that the Group will be able
to continue in operation and meet its liabilities as they fall due over the three-year period ending 31 December 2026.

CHIEF EXECUTIVE OFFICER’S REVIEW
Challenging macro-economic conditions negatively
impacted the diamond market in 2023.
2023 was a challenging year globally, with surging inflation and interest rates in major economies, two international conflicts and a
subdued overall global economic outlook. The Israel-Hamas conflict in Gaza is detrimental to the diamond market because Tel Aviv is
one of the world’s most important diamond trading centres. The attacks by Yemen’s Houthi rebels on cargo vessels in the Red Sea from
the beginning of 2024 are expected to further challenge supply chains not yet fully recovered after the COVID-19 pandemic.
In the diamond industry, aggressive overstocking post-COVID-19 led to high inventory levels resulting in an inevitable oversupply of
polished diamonds. Given China’s importance as a consumer of polished diamonds, the sluggish growth of its economy contributed to
the decrease in demand, which was exacerbated by slow economic growth in other important consumer markets such as the US and the
rest of Asia. There is evidence of below market sales of large, high-value polished diamonds by certain manufacturers that has had a
detrimental effect on the top end of the diamond market. These factors have placed severe pressure on rough and polished diamond
prices during 2023.
The manufacturing of lab-grown diamonds has continued to double every year since 2015 and is forecast to reach 20 million carats in
2024. Although lab-grown diamonds have increased in availability and popularity due largely to their favourable price point, we have not
seen it impact the demand for Letšeng’s large, high-value diamonds; these goods are on the opposite side of the spectrum when it
comes to value and quality. Lab-grown diamonds have taken the place of other natural diamond look-alikes such as cubic zirconia and
moissanite, and are regarded as consumer goods, not investments. Lab-grown diamonds can be compared to what “fast fashion” is to
the premium clothing industry. In order to clearly differentiate them from natural diamonds, and avoid any confusion of the two by
consumers, it is notable that the French Government recently ruled that these diamonds may only be referred to as “synthetic”.
The Letšeng mine continued to grapple with increased operating costs, mainly because of inflation and higher diesel consumption due
to Eskom’s continued load shedding, which increased its reliance on diesel-powered generators. Considering these challenges, there
was no choice but to relentlessly focus on cost control measures, enhance operational efficiencies, rigorously evaluate capital projects
against measurable returns, and defer non-essential longer-term projects.

Clifford Elphick
CEO
As reported in our Half-year Report 2023, a further right-sizing programme commenced at Letšeng in March 2023 and the workforce
element of the programme was completed in June. The programme was aimed at more effectively and efficiently aligning the workforce
to operational requirements.
Letšeng concluded the early termination of the mining services agreement with MMIC on 1 December. It is pleasing to report the
smooth transition to owner mining, which included the transfer of all relevant equipment and employees to Letšeng. Employment was
effective 1 February 2024 and MMIC employees remained on contract until this date. The process was well managed by senior
management, and we are already seeing significant benefits from this transaction, both financially and operationally. The full details of
the transaction are included in the CFO Review on page 34.
Several changes were made to the senior leadership structure at Letšeng. Kelebone Leisanyane retired from his position as CEO of
Letšeng at the expiration of his contract at the end of June. We would like to thank Kelebone for his valuable contribution during his
tenure as CEO. He was succeeded by Motooane Thinyane, previously the Head of Operations. Motooane has been a senior manager
and executive of Letšeng for the past eight years. An important part of his role will be spearheading the identification and
implementation of appropriate alternative energy solutions. Gideon Scheepers was appointed to the position of Operations Director.
Gideon has 32 years of extensive experience in diamond mining and related processes, many of these in the Lesotho diamond mining
industry.
Glenn Turner, the Chief Commercial and Legal Officer of the Group, retired at the end of April. Glenn’s expertise and leadership was
invaluable to the Group over the past 16 years. I have worked with Glenn for many years both at De Beers and subsequently at Gem. We
have relied heavily on him as an experienced and deeply trusted colleague. His sound judgement, legal knowledge and commercial
experience have helped steer the Group through challenging times and his absence will leave a huge gap. We wish him all the best with
this new chapter in his life.
We continue to work well with the newly elected Lesotho Government. Three new non-Executive Directors appointed by the Lesotho
Government joined the Letšeng Board during the year. We welcome them and look forward to their valuable contribution and support
while we navigate a challenging macro-economic and operating environment. We would also like to thank the outgoing Directors for
their dedication and commitment during the time they served on the Letšeng Board.
We concluded the implementation of our TCFD adoption strategy in 2023 and are actively working towards our decarbonisation target
of a 30% reduction in Scope 1 and 2 emissions by 2030 (measured against our 2021 footprint). We are pleased to report that in 2023 we
achieved a 26% reduction against the 2021 baseline of our decarbonisation target.
Letšeng’s underground pre-feasibility study was completed during the year and the results show that underground mining in the
Satellite pipe is not currently economically viable. These options for both the Main and Satellite pipes may be revisited when macro-
economic and diamond market conditions improve. Letšeng will therefore, on current and foreseeable economics, continue with open
pit mining and pursue mine plan optimisation options to ensure maximum value for all stakeholders.
Our NI 43-101 Technical Report containing Letšeng’s 2024 Resource and Reserve Statement will be published following an in-depth
resource development programme over the past number of years. The detailed documents will be available on the Group’s website at
www.gemdiamonds.com.
Refer to the COO Review for more details on the underground study on page 44 and the 2024 Resource and Reserve statement on
page 45.
EXTRACTING MAXIMUM VALUE FROM OUR OPERATIONS
We have operated safely, responsibly and efficiently during the year with an ongoing focus on cost containment and control and
enhancing operational efficiencies. Production stabilised and volumes of ore treated increased in H2 2023 compared to H1 2023, with
the implementation of targeted initiatives to improve plant stabilisation and increase diamond recoveries.
Five diamonds greater than 100 carats were recovered during the year. Exceptional sales during the year included a 7 carat pink
diamond that was sold for US$282 889 per carat, the third-highest dollar per carat achieved for a Letšeng diamond. In addition, three
large high-quality Type IIa white diamonds of 58 carats each were sold for US$36 399 per carat, US$34 441 per carat and US$34 252 per
carat, respectively.
We have an effective, transparent and competitive tender sales process in Antwerp. The limited supply agreement that was concluded
in 2022 with two important diamond manufacturing customers who supply polished diamonds to some of the world’s most premium
luxury brands has continued. These diamonds are polished to precise specifications required by the brands and additional value is
realised for the Group. This is a further step in the Group’s strategy of focused delivery of top-quality diamonds to promote Letšeng as
an exceptional diamond brand, Lesotho as the origin and therefore to achieve premium prices for its diamonds.
The operational performance of the Letšeng mine is discussed in more detail in the COO Review on page 41.
The challenging macro-economic environment and downturn in the diamond market resulted in pressure on rough diamond prices,
which had a direct and significant impact on our financial results. The average price achieved decreased to US$1 334 per carat
compared to US$1 755 per carat in 2022. The lower prices achieved resulted in total revenue of US$140.3 million and underlying
EBITDA
1
of US$15.2 million. The Group ended the year in a net debt
2
position of US$21.3 million.

WORKING RESPONSIBLY AND MAINTAINING OUR SOCIAL LICENCE
One of our proudest accomplishments in 2023 was the Group’s safety performance. There were no fatalities for the fourth consecutive
year, two LTIs (2022: three), and we achieved an overall AIFR of 0.67 (2022: 0.70), our lowest AIFR on record. The drive to mature the
organisational safety culture since June 2021 has yielded positive results of which we are very proud. We will continue to entrench a
workplace safety culture founded on individual responsibility, mutual care and collaboration.

We adhere to the highest environmental management standards. We are proud to report that Gem Diamonds’ work in sustainable
water treatment and community water initiatives during 2022 was recognised by the award in the Water category conferred by the
Mining Indaba Sustainability Committee Junior ESG Awards Committee in February 2023.
In order to improve the quality of water from the mine, we introduced two small-scale mobile bioremediation plants in 2023. Results
from these plants indicate an effective reduction in nitrates in the water flowing through these plants. Construction of a ~300 kilolitre per
day plant was completed in December 2023 and commissioned in February 2024.
Our residue storage facility management process aligns with the ICMM’s GISTM. Our residue storage and freshwater facilities are
subject to regular inspections by external experts. These professional external reviews, together with the internal governance,
management, monitoring and reporting processes, ensure that our residue storage and freshwater dam management is both effective
and closely monitored.
In 2023, we adopted two additional UN SDGs, being Zero Hunger and Climate Action. Our CSI activities are focused on supporting
infrastructure development, education and health while assisting and stimulating small businesses. In 2023, we supported small
agricultural operations including those in egg, vegetable and dairy production, provided scholarships for tertiary education, and
constructed classrooms at schools. From 2016 to 2023 the Group invested US$4.8 million in sustainable CSI initiatives.
In 2023, Letšeng contributed a total of US$15.5 million (LSL285.8 million) to the Lesotho fiscus in the form of taxes and royalties alone.
We are proud of our contribution to this developing economy and our position as a significant taxpayer and employer.
PREPARING FOR THE FUTURE
In 2024, we aim to deliver the business plan approved by the Board. This includes achieving our financial and operational targets with a
focus on cost control measures and improved operational efficiencies. Every single contract, capital project and expense is being
interrogated and scrubbed for absolute necessity. We will continue to focus on our safety performance by maintaining the cadence of
safety interventions, critical control management, visual safety leadership and communication with the workforce.
The increase in load shedding and consequent reliance on diesel-powered generators with their associated costs have intensified our
need to identify and implement alternative energy solutions for the short, medium and long term. The criteria for these solutions are
that they must be renewable, reliable and reduce costs. We are making progress on this important workstream.
Our capital plans include funding for projects that will sustain growth and value creation. The planned capital-intensive projects in 2024,
although not financially significant, include recovery plant and sort house enhancements, the required extension of the Patiseng coarse
residue storage facility to align its capacity with future mining activities, and necessary screen replacements in both the treatment plants.

OUTLOOK
Pressure on the diamond market has persisted into 2024, although there have been some signs of price recovery at the top and bottom
end. We are cautiously optimistic that prices will stabilise and that there will be some growth towards the end of 2024. Global economic
growth outlooks for major economies and important diamond consumer markets such as the US and China remain uncertain. It is worth
noting that almost half of the global population is expected to participate in national elections during 2024, which will likely cause
further economic and geopolitical uncertainty.
It is pleasing to note that the global luxury market continued to grow in 2023 and remains poised to expand further in 2024. The luxury
market appears well positioned to cope with economic turbulence, with a larger and more resilient consumer base.
In the medium to long term, rough diamond prices should be supported by favourable demand and supply fundamentals, with a
projected further decrease in natural rough diamond supply. This dynamic of rising demand and constrained supply is expected to
benefit high-quality rough diamonds in particular. The fundamentals that underpin our business are sound and strongly position Gem
Diamonds for success.
APPRECIATION
I would like to thank the Board for their support and commitment in 2023. We are grateful for our workforce and appreciate the
dedication required to deliver the safety performance we saw in 2023. We also appreciate their commitment to delivering our strategic
goals and to living our values. I would like to thank our customers for their continued trust in Letšeng’s diamonds, and our shareholders
for their support. Finally, I would like to thank the Government of the Kingdom of Lesotho for their support and open and transparent
communication. We look forward to a productive 2024.

CHIEF FINANCIAL OFFICER’S REVIEW
The financial performance of the Group in 2023 was
disappointing, driven by a downturn in the diamond
market that resulted in lower diamond prices achieved.
The turbulent global economic conditions from the previous year continued into 2023 with high inflation, interest rate hikes and slow
overall economic growth in major economies. The continued Russian invasion of Ukraine and the recent conflict in Gaza further
impacted the global economy and specifically the diamond market. Locally, the ever-increasing load shedding by the South African grid
electricity supplier, Eskom, put pressure on the operating environment and costs. These factors had a significant impact on diamond
prices achieved and costs incurred during the year, resulting in lower EBITDA
compared to 2022. This necessitated a renewed focus on
cost containment and improvement in operational efficiencies.
Operationally, Letšeng performed in line with expectations despite several challenges posed by high rainfall and increased electricity
supply disruptions (refer to the COO Review on page 41). The pressure experienced on the diamond market significantly impacted
rough and polished diamond prices and resulted in an average price of US$1 334 per carat for the year, with revenue from the sale of
rough diamonds of US$139.4 million. In addition, US$0.9 million of margin uplift was generated, bringing total revenue for the year to
US$140.3 million.
Underlying EBITDA decreased to US$15.2 million from US$43.7 million in 2022. The Group reported a loss attributable to shareholders
for the year of US$2.1 million, equating to a basic loss per share of 1.5 US cents on a weighted average number of shares in issue of
139.5 million.
The Group ended the year with a cash balance of US$16.5 million and drawn down facilities of US$37.8 million, resulting in a net debt
position of US$21.3 million and available undrawn facilities of US$45.9 million.

Revenue
Revenue decreased 26% compared to 2022, mainly due to lower prices achieved as a result of a downturn in the diamond market and a
decrease of 3% in carats sold (104 520 carats compared to 107 498 in 2022). Rough diamond revenue of US$139.4 million (2022:
US$188.6 million) was generated at Letšeng, achieving an average price of US$1 334 per carat (2022: US$1 755 per carat).
Additional revenue is generated through an arrangement with two diamond manufacturing customers to supply polished diamonds to
some of the world’s most premium luxury brands, and other partnership arrangements. These agreements allow the Group to share in
the margin uplift on the sale of polished diamonds. In 2023, additional revenue of US$0.9 million (2022: US$0.3 million) was generated
from these arrangements.

Insourcing of the mining activities
Matekane Mining Investment Company (Proprietary) Limited (MMIC) has been the provider of mining services to Letšeng since 2005.
Following the election of Mr Sam Matekane (the ultimate owner of MMIC) as Prime Minister of Lesotho in October 2022, Letšeng
carefully considered its options to resolve the potential conflict of interest created by being in a business relationship with a politically
exposed person.
Effective 1 December 2023, Letšeng reached an agreement with MMIC to early terminate the mining services contract, 11 months ahead
of its scheduled contractual end date of 31 October 2024, and insourced these activities. Letšeng acquired the mining fleet and support
equipment that was used exclusively for Letšeng, and offered employment to those MMIC employees working exclusively for Letšeng, in
line with operational requirements. Employment was effective 1 February 2024 and MMIC employees remained on contract until this date.
The total purchase price, which was determined with the assistance of external third-party valuators, was US$22.7 million. Payment terms
were agreed whereby US$13.0 million was paid on the effective date, US$9.3 million was paid in January 2024, and a retainer of US$0.4
million was withheld for equipment under repair at the effective date and subsequently settled in early March 2024.
The full purchase price was capitalised to the statement of financial position and the fleet and equipment will be depreciated over the
useful life of each asset based on the available production hours. The financial results for the year include one month of depreciation on
the acquired fleet.
This transition to owner mining creates further opportunities for Letšeng to maximise mining efficiencies, reduce costs through
eliminating contractor margins, and manage mining procurement directly, and enables further flexibility in the planning and execution
of its mining activities. All these factors will contribute to a more efficient and cost-effective operation. The full benefit of the insourcing
of the mining activities will be seen from 2024 onwards.

Expenditure
Energy costs
The increased load shedding by Eskom in 2023, which impacted 335 days of the year (compared to 205 in 2022), has necessitated an
increase in diesel usage due to Letšeng’s reliance on diesel-powered generators to operate the treatment plants uninterruptedly. This
increase was partially set off by a decrease in diesel usage for mining activities due to lower volumes mined (refer to the COO Review on
page 41) and the full year benefit of previously implemented lower-energy consumption initiatives.
The net impact was a 0.1 million litre increase in diesel consumption compared to the prior year. The average cost per litre of diesel
decreased by 2% from 2022. Overall, it resulted in a 1% decrease in diesel costs, in local currency, to LSL336.0 million (US$18.2 million)
from LSL340.6 million (US$20.8 million) in 2022.
Grid electricity usage decreased due to increased load shedding during the year. The marginal 3% decrease in cost to LSL54.9 million
(US$3.0 million) was set off by a 7.9% rate increase.
Overall energy costs, including diesel and electricity, amounted to LSL390.9 million (US$21.2 million) in 2023 (2022: LSL397.0 million,
US$24.3 million), a 2% decrease from 2022 in local currency. Energy costs as a percentage of direct cash costs remained unchanged at
27%, and the energy cost per tonne treated increased by 8% from LSL72.09 in 2022 to LSL77.79 in 2023, driven by lower volumes of
tonnes treated.

Non-cash accounting charges include waste stripping amortised, inventory and ore stockpile adjustments, and finance lease costs, and exclude depreciation and mining asset
amortisation.
Operating expenditure
Group cost of sales (excluding depreciation) decreased by 12% in 2023 to US$102.1 million from US$116.3 million in 2022.
• Direct cash costs (excluding waste) remained virtually unchanged at LSL1 449.8 million (2022: LSL1 448.6 million). In 2023 these costs
were affected by energy costs (detailed above), price increases from suppliers on explosives, equipment, spare parts and tyres, and
additional once-off severance payments and related consulting fees due to the right-sizing of the Letšeng operation (refer to the
COO Review on page 43). Direct cash costs per tonne treated increased by 14% to LSL288.54 from LSL252.50 in 2022, impacted by
the lower volume of tonnes treated in the year. The third plant operator’s (Alluvial Ventures or AV) contract expired on 30 June 2022.
Ore tonnes treated decreased 9% to 5.0 million tonnes (2022: 5.5 million tonnes of which AV contributed 0.4 million tonnes). On a
like-for-like basis (excluding the impact of AV), the 2022 unit costs would be LSL274.48 per tonne treated, resulting in a year-on-year
increase of 11%, which is driven by the additional costs mentioned above.
• Non-cash accounting charges refers to waste amortisation, stockpile and diamond inventory movements and finance lease costs.
These charges decreased 4% to LSL431.5 million (2022: LSL451.7 million), mainly due to the combination of an increase in total waste
amortisation charges of LSL723.2 million (2022: LSL594.0 million), despite lower tonnes treated during the year, and the impact of the
increase in stockpile tonnes on hand from 0.7 million tonnes in 2022 to 1.1 million tonnes in 2023. The increase in waste amortisation
charges was mainly driven by the reduction of the anticipated future ore tonnes from SC6W as a consequence of an updated pit
design (refer to the COO Review on page 47). In US dollar terms, waste amortisation charges increased by 8% to US$39.2 million
compared to US$36.3 million in 2022.
• Total operating costs in local currency decreased marginally to LSL1 881.3 million (2022: LSL1 900.3 million), which includes the impact
of direct cash costs and non-cash accounting charges detailed above. The unit cost per tonne treated increased 8% to LSL374.41 per
tonne treated (2022: LSL345.09 per tonne treated), mainly due to the 9% decrease in tonnes treated in the year.
• Waste cash costs decreased by 14% to LSL583.8 million from LSL677.7 million in 2022, which is in line with the 13% reduction in waste
tonnes mined (8.8 million tonnes compared to 10.2 million tonnes in 2022). Initiatives such as the steepening of slopes in the Main pit
and decreasing of waste hauling distances, implemented in 2022, resulted in a 1% decrease in waste cash cost per waste tonne to
LSL66.03 (2022: LSL66.74) despite the lower waste tonnes mined.

US dollar-reported costs
Gem Diamonds’ revenue is generated in US dollars, while the majority of operational expenses are incurred in the relevant local
currency in the operational jurisdictions. Local currency rates for the Lesotho loti (LSL) (pegged to the South African rand) and Botswana
pula (BWP) were weaker against the US dollar compared to 2022, which decreased the Group’s US dollar-reported costs and increased
local currency cash flow generation. The fluctuation of the exchange rates are set out in the table below:

Royalties and marketing costs
In terms of Letšeng’s mining lease, royalties are paid to the Government of the Kingdom of Lesotho on the value of rough diamonds
sold. The Group’s sales and marketing operation in Belgium incurs costs relating to diamond selling and marketing. Royalties and
selling costs decreased by 25% to US$15.3 million (2022: US$20.3 million) in line with the decrease in revenue.
Corporate costs
The technical and administrative office in South Africa and head office in the UK provide expertise in all areas of the business to realise
maximum value from the Group’s assets. Central costs are incurred in South African rand and British pounds respectively.
Corporate costs (excluding depreciation) were US$7.7 million, representing a 10% decrease from 2022. In 2023, US$0.2 million of project
costs were incurred on the ongoing sales process of Ghaghoo and investigating external growth opportunities (2022: US$0.1 million).

Capital expenditure
Total capital expenditure (excluding waste stripping) was US$30.4 million during the year (2022: US$11.9 million). The increase in 2023
was mainly due to the acquisition of the mining fleet and support equipment from MMIC for US$22.7 million, as detailed on page 35.
The replacement of the PCA and the underground study that commenced in 2022 were completed. Three bioremediation plants were
constructed, with the large-scale, ~300 kilolitre per day plant being commissioned in February 2024.
Cash on hand
The Group ended the year with cash on hand of US$16.5 million (2022: US$8.7 million) and net debt of US$21.3 million, which was a
decrease in net cash of US$24.6 million year on year. Group cash generated by operations was US$56.1 million before capital and waste
investment of US$57.1 million.
Loans and borrowings
The Group-wide debt facilities for Letšeng (LSL450.0 million and ZAR300.0 million) and Gem Diamonds (US$30.0 million), which were
concluded in December 2021 for an initial three-year period, are due to expire in December 2024. The process to extend or renew the
revolving credit facilities will commence in Q2 2024.
Letšeng has a ZAR100.0 million (US$5.5 million) general banking facility with Nedbank Limited (acting through its Nedbank Corporate
and Investment Banking division) reviewed annually. The facility was utilised from time to time during the year and was fully repaid by
year end.
The funding partners to the existing facilities are Nedbank, Standard Bank and Firstrand Bank (through their respective operations).
Nedbank’s portion of the funding, totalling US$29.9 million, is a sustainability-linked loan (SLL), an innovative structure that links the
margin and resultant interest rate on the SLL to the Group’s ESG performance. The margin on the SLL will decrease subject to the
Group meeting certain carbon reduction and water conservation KPIs that are aligned with the Group’s sustainability strategy. These
KPIs are assessed at the end of every financial year.
Performance
review
Gem Diamonds Limited Annual Report and Accounts 2023

The two KPIs included for the SLLs both need to be met at each measurement date before the margin reduction on these loans
becomes effective. At 31 December 2023, both the carbon emission and water conservation KPIs were met and therefore the margin
reduction is expected to apply to any outstanding balance on these facilities in 2024.
In 2022, Letšeng implemented a four-and-a-half-year facility agreement with Nedbank for the replacement of the PCA for an amount of
ZAR136.4 million (US$8.0 million). The facility is underwritten by the Export Credit Insurance Corporation of South Africa (ECIC). At the
end of the availability period on 30 November 2023, an amount of LSL132.0 million (US$7.2 million) was utilised and the remaining
balance expired. Quarterly repayments of this facility will commence from Q1 2024 until May 2027.
At year end, the Group had utilised facilities of US$37.8 million, resulting in a net debt position of US$21.3 million and available facilities
of US$45.9 million. Gem Diamonds, the Company, ended the year with US$6.0 million of its facility drawn down (2022: nil) and
US$24.0 million available. Letšeng ended the year with US$24.6 million (2022: nil ) of its revolving credit facility utilised and
US$16.4 million available.

Ghaghoo
The Board and management remain committed to exiting the Ghaghoo Diamond Mine in Botswana, either by sale, closure or handover
of the mine. Ghaghoo ceased to be classified as a discontinued operation held for sale as at 31 December 2022 due to the highly
probable requirements set out in IFRS 5 not being met.
Care and maintenance cash costs decreased to US$1.8 million in 2023 (2022: US$1.9 million), which amount is included in other
operating expenses in the financial results. An additional US$0.2 million (2022: US$0.2 million) on the unwinding of the environmental
rehabilitation provision resulted in a non-cash interest charge which is included in finance costs. In addition, a US$0.4 million reduction
in the rehabilitation provision has been included in operating income and expenses.
A solar power solution was installed during the year. The solar plant was commissioned in January 2024 and completely replaces the existing
diesel generator. This will result in future cost savings as it will eliminate costs related to generator rentals, diesel usage and transport.
The operation has also commenced site clean-up activities to prepare it for handover, the costs of which are included in the above cash costs.
Insurance
The perception of risk in the mining industry has improved, with insurers offering more competitive rates for mining companies. In 2023,
insurance premiums for the Group were 15% lower compared to 2022. The Group is in the third year of a five-year multi-aggregate
insurance policy to mitigate the increased risk of higher deductibles in the unlikely event of an unexpected loss.
Letšeng’s insurance claim relating to diesel theft, which was identified in 2021, was settled during the year and is included in other
operating income in the financial results. The business interruption claim for insured losses arising out of the COVID-19-related
shutdown in 2020, where the mine was required to be placed on care and maintenance, is ongoing and we hope to receive an
appropriate settlement in 2024.

Share-based payments
The share-based payment charge for the year was US$0.3 million (2022: US$0.3 million). At the AGM on 2 June 2021, shareholders
approved the 2021 Remuneration Policy, which included the introduction of a post-termination shareholding, an employee pension
alignment plan, as well as the new Gem Diamonds Incentive Plan (GDIP) for Executive Directors. On 21 April 2023, 1 060 055 nil-cost
options were granted to certain key employees and Executive Directors under the GDIP. Refer to Note 26, Share-based payments on
page 167 for more detail.
TAXATION
The Group applies all relevant principles in accordance with prevailing legislation in assessing its tax obligations. The Group’s effective
tax rate was 72.0%. Most of the Group’s taxes are incurred in Lesotho, which has a corporate tax rate of 25%. The effective tax rate is
above the Lesotho corporate tax rate mainly due to deferred tax assets not recognised on losses incurred in other operations, the
impact of the alignment of foreign tax at different rates, partially offset by withholding tax overpaid in prior periods and refunded in full
by the Revenue Services Lesotho (RSL) during the year. Refer to Note 6, Income tax expense on page 148 for more detail.
The Group continues to pursue a long-standing legal matter relating to an amended tax assessment that was issued to Letšeng by the
RSL in December 2019, contradicting the application of certain tax treatments in the current Lesotho Income Tax Act 1993. We expect
to pursue this matter in the courts in 2024. We have sought senior legal counsel and their advice indicates good prospects for success.
Refer to the accounting treatment for this matter, Note 1.2.26, Critical accounting estimates and judgements for further detail.
OUTLOOK
In light of the many external macro-economic factors negatively impacting our business, we have renewed our focus on cost
containment measures, tightening capital allocation decision-making and enhancing operational efficiencies. The insourcing of the
mining activities is expected to deliver significant savings. A key focus for 2024 will be the extension or renewal the Group’s facilities
which expire on 22 December 2024.

CHIEF OPERATING OFFICER’S REVIEW
The overall operational performance of the Group in 2023
was pleasing, driven by a focus on safety and operational
efficiency.
Market conditions and the continuing pressure on revenue in 2023, coupled with the ever-rising cost of operating, including longer
hauling distances due to deeper pits, and increased load shedding, necessitated a reinforcement of our focus on operational
efficiencies and cost containment, while at all times ensuring that we meet our production targets safely, responsibly and sustainably.
The challenges of lower revenues and increasing costs are not always within our control. To meet these challenges head-on however, we
made significant changes to management, workforce and operating methodologies at Letšeng and Ghaghoo in 2023. This required a
direct focus on operating more efficiently to reduce, or at the very least contain, those operational costs that are within our control.
The implementation and integration of sustainability initiatives at our operations over the past few years, in particular our focus on
reducing energy consumption and associated costs, positioned the Group well to navigate a difficult financial year in 2023. This is
evident in reduced costs and decarbonisation related to waste mining in particular, and the successful implementation of several other
energy-efficiency initiatives. In 2023, we recorded a 26% decrease in our Scope 1 and 2 emissions and a 25% decrease in diesel
consumption-related emissions when compared to our 2021 baseline carbon emission footprint.
One of our proudest achievements in 2023 is our safety performance. The health and safety of our workforce remains paramount, and it
is very pleasing to reap the rewards of a three-year safety campaign that started with a 24-hour stop-for-safety in June 2021. Achieving
our lowest all injury frequency rate (AIFR) on record is testament to our commitment to achieving a zero harm operation and the
relentless focus of leadership, management and each employee to achieve this.
We have also completed the NI 43-101 Technical Report containing Letšeng’s 2024 Resource and Reserve Statement, which will be
available on the Group’s website at www.gemdiamonds.com.

The Group's safety culture is founded on our commitment to zero harm and our strong belief that all injuries can be prevented.
Letšeng’s safety performance in 2023 was of the highest standard, with zero fatalities (2022: zero), two LTIs (2022: three), an improved
LTIFR of 0.10 (2022: 0.13) and our lowest AIFR on record of 0.67 (2022: 0.70). Our improved safety performance does not happen by
chance but is a direct result of the relentless effort and commitment of executive leadership and operational management in the
implementation of the organisational safety maturity strategy. This strategy addresses critical safety risks, enhances safety-specific
leadership visibility, and engages with the workforce to implement engineering and behaviour-focused controls to more specifically
prevent safety incident reoccurrences. A focused safety programme was guided by independent subject matter experts and included
mentoring senior management on best practice safety leadership and successfully implementing a critical control management strategy.
The safety of our workforce remains our highest priority and we will continue to build on the organisational safety maturity at our
operations, which is founded on and entrenched in a safety culture of visible safety-focused leadership, individual responsibility and
accountability, mutual care and collaboration.

Operationally, 2023 was a year of two halves. Following a positive start in Q1 2023, Letšeng faced numerous challenges and changes in
Q2 2023, culminating in the finalisation of the right-sizing programme and a change in senior management in June 2023. Operational
challenges at Letšeng during this period included high rainfall, instability in the performance of the treatment plants and continued load
shedding by Eskom, which resulted in poor overall treatment efficiencies and increased reliance on more expensive diesel generators to
power operations. An intensified focus on the identification and implementation of initiatives to optimise and improve operational
performance and efficiencies and to significantly reduce costs commenced in Q3 2023, resulting in a marked improvement in
operational performance seen in H2 2023 compared to H1 2023.
The implementation of a number of initiatives to slow down the instantaneous rate at which ore is fed into the treatment plants
significantly improved overall stability. This in turn materially improved the consistency of higher daily overall plant utilisation. The newly
built Primary Crushing Area (PCA), which was commissioned in Q4 2023, further contributed to the improved performance by providing
the plant with a consistent feed of well-fragmented ore. The initial benefit of these initiatives when comparing H2 2023 to H1 2023 is set
out in the table below:
KPI Unit
H2 2023 H1 2023 % change

Carats recovered carats 59 055 50 601 17
Grade cpht 2.48 2.05 21
The 4% increase in ore treated in H2 2023 can largely be attributed to the improved plant stability and higher overall daily utilisation.
Overall plant utilisation improved from 75% in H1 2023 to 81% in H2 2023. Plant stability further contributed to improved recoveries in
H2 2023, with a notable 17% increase in carats recovered and a 21% improvement in the grade.
Waste tonnes mined
Total waste tonnes mined in 2023 decreased 13% to 8.8 million tonnes from 10.2 million tonnes in 2022. This was in line with the planned
2023 waste mining profile, which was further reduced in Q4 2023 to align with the ore treatment performance. Initiatives to further
optimise waste mining and reduce associated costs continued to be implemented, and during 2023 this included a re-design of the Cut
4 West cutback in the Main pit to reduce waste, and the implementation of a new fleet management system that improved fleet
productivity, availability and utilisation.

plan, taking into account the reduced ore treatment capacity in 2023 following the expiry of the Alluvial Ventures (AV) processing
contract on 30 June 2022. This was partially off set by increased mining to the surface ore stockpiles in 2023.
Ore treated
Letšeng’s two plants treated 5.0 million tonnes of ore during 2023 (2022: 5.5 million tonnes). The reduction in total ore tonnes treated in
2023 compared to 2022 was primarily due to the expiry of AV’s processing contract, which contributed 0.4 million tonnes in 2022. The
balance of the fewer tonnes treated in 2023 compared to 2022 was mainly as a result of plant performance and instability experienced in
H1 2023. Of the total ore treated, 2.0 million tonnes were sourced from the Main pipe and 3.0 million from the Satellite pipe, this being
in line with the planned Satellite/Main pipe ore contribution for 2023.
The biggest operational challenge in 2023 was the continued occurrence of more frequent and longer periods of load shedding by
Eskom, the South African grid electricity supplier. Letšeng’s generator capacity is sufficient and the synchronised switch-over from grid
to generator power is effective (provided Eskom adheres to its load shedding schedule), but the additional running hours and strain on
what was designed as a back-up generator system requires increased maintenance and heightens the risk of generator plant and
equipment breakdowns. The increased utilisation of diesel generators, resulting in considerably higher volumes of diesel being
consumed by the treatment plants in the year, had a significant negative impact on treatment operating costs.
Total carats recovered
Total carats recovered in 2023 increased 3% to 109 656 carats (2022: 106 704 carats), due primarily to differences in ore mix year on year
and improvements in plant stability in H2 2023, resulting in improved recoveries.
The coarse tailings mobile XRT sorting machine recovered 367 carats in 2023 (2022: 774 carats) from re-treating current coarse recovery
tailings, and an additional 5 206 carats (2022: 2 657 carats) were recovered by the fines tailings mobile XRT sorting machine, which re-
treated current fines recovery tailings.
The overall grade for 2023 was 2.18 cpht, a 12% increase compared to 1.94 cpht in 2022, which was marginally better than expected. The
contribution of higher grade material from the Satellite pipe accounted for 59% of ore treated during the year (2022: 55%).
Capital projects
Capital expenditure allocation during 2023 was thoroughly interrogated against necessity and applied in line with operational and cash
management requirements. Material capital projects at Letšeng in 2023 included:
• completion of the PCA replacement project, which was successfully commissioned in Q4 2023;
• completion of the Satellite pipe underground study;
• final design and construction of the bioremediation plant; and
• purchase of the mining fleet and equipment in the transition to owner mining.
Details of overall costs and capital expenditure incurred at Letšeng are included in the CFO Review on page 34.
The planned capital spend at Letšeng for 2024 includes necessary modifications and upgrades to the recovery plant and final sort, the
development of the next phase of the Patising coarse tailings extension project to ensure future capacity, and other smaller projects,
including necessary upgrades to storage facilities, Plant 1 scrubber shell replacement and resource drilling.
Enhancing operational efficiencies
A change in operational requirements, together with significant pressure to further reduce operating expenses in line with challenging
market conditions and lower rough diamond prices, required Letšeng to critically review all aspects of its business to maximise
operational efficiency and effectively control costs to ensure continued business sustainability.
The right-sizing programme at Letšeng, which affected a total of 327 positions, including contractors, was completed in June. The
programme was aimed at more effectively and efficiently aligning the workforce to operational requirements. In addition, a number of
changes were made to the management team at Letšeng, including the appointment of Gideon Scheepers to the position of
Operations Director. Gideon has 32 years of extensive experience in diamond mining, treatment and related processes, and following
his appointment in June, drove the implementation of significant improvements at the operation in H2 2023, particularly in mining,
treatment and site management.
A smooth transition to owner mining was concluded in Q4 2023 (refer to the CFO Review on page 35), with no interruption to
production or mining activities. In addition to an immediate decrease in operating costs, there is room to further improve operational
efficiencies as Letšeng management now has direct control over its mining fleet and execution of the mine plan. This will also assist in
reducing “day-works” costs for other necessary projects around site, including concurrent rehabilitation.
The management of the recovery plant was brought in-house from Minopex to ensure direct control and management over what is
arguably the most important part of the treatment process along with the final sort.
In addition, a revision to the catering and housekeeping contract on site resulted in the housekeeping and laundry activities being
insourced, with the contractor providing the catering services only for the remainder of the contract term.
All operational contracts are undergoing rigorous reviews to ensure optimisation, efficiency and effective cost control management as a
top priority.

Large diamond recoveries
In 2023, Letšeng recovered five diamonds greater than 100 carats (2022: four), including three high-quality Type IIa white diamonds of
120.43 carats, 117.47 carats and 112.46 carats, respectively. A total of 131 greater than 100 carat diamonds have been recovered at
Letšeng since 2006, and we are pleased to report that three more greater than 100 carat diamonds have been recovered to date in Q1
2024. Total diamonds recovered greater than 10 carats decreased by 5% year on year, mostly in the 10 to 20 carat and 60 to 100 carat
size categories. The lower number of diamonds in the larger categories can be primarily attributed to the resource domains that were
mined in both the Satellite and Main pipes in 2023. 22 diamonds sold for over US$1.0 million each in 2023, generating revenue of
US$40.8 million.

Diamond sales
Eight large and four small rough diamond tender viewings were held in Antwerp during the year.
A total of 104 520 carats were sold in 2023 (2022: 107 498) and Letšeng generated rough diamond revenue of US$139.4 million (2022:
US$188.6 million) at an average price of US$1 334 per carat (2022: US$1 755). The significant challenges experienced in the diamond
market, discussed in the CEO Review on page 30, coupled with the reduced volume of large high-value diamonds in 2023, were the
primary factors behind the lower average price and revenue achieved in 2023.
The Group supports the GIA’s blockchain technology to inform and assure consumers about the ethical and socially supportive footprint
of our diamonds. Blockchain technology can link the source of rough diamonds to the final polished diamonds, thereby proving their
authenticity, provenance and traceability, and supporting ethical sourcing and processing in the diamond value chain.
Underground study
A conceptual desktop study for an underground mining operation in the Satellite pipe post the current Cut 5 West (SC5W) open pit
cutback was completed in November 2021. The outcome indicated potential for underground mining and recommended that a
comprehensive Underground Feasibility Study be undertaken to confirm the feasibility thereof to most optimally and economically
extend the life of mine for the Satellite pipe. The objective of the proposed study was to upgrade the desktop study to the confidence
level of a feasibility study and to develop a transition model for an underground operation once the life of the Satellite pit reached
maximum depth achievable through the current open pit mining. The study commenced in mid-2022 to (i) assess the viability of an
earlier shift to underground mining of the Satellite pipe, and (ii) inform the trade-off between an underground mining option and the
next open pit cutback in the Satellite pipe Cut 6 West (SC6W) post the completion of SC5W in 2024/5.
The project focused on the viability of the mining block within the indicated resources zone of the Satellite pipe, but also included the
assessment of additional levels, to the point where the project no longer added positive financial returns. Following numerous iterations
of the mining strategy, a three-level sub-level retreat was identified with the caving method as the most efficient and appropriate
underground mining method for the available ore within the Satellite pit. To improve the economic viability of the mine, the study
focused on several optimisation strategies, particularly with regards to mining costs. A detailed analysis of the cost breakdown was
conducted to identify areas of potential savings and to explore alternative contracting models.
The economic viability and performance of the underground operation was determined through developing a detailed financial model
founded on the results derived from the study and other available information. Unfortunately, at a mid-point review held in June 2023,
the preliminary analysis at that time revealed a negative net present value of such an underground project in the Satellite pipe. Further
sensitivity analysis was conducted in H2 2023 to ascertain the impact on project value due to potential variability in significant value
drivers such as capital expenditure, diamond selling prices and operating costs. Following this analysis and a further review of capital
expenditure and operating costs in particular, it was clear that the underground project for the extension of life of the Satellite pipe was
not economically viable under current macro-economic conditions and the current state of the diamond market. The study was
therefore halted at a pre-feasibility level to avoid spending unnecessarily on further geotechnical and hydro-technical drilling work at
this time. Underground mining for both the Main and Satellite pipes may again be reconsidered should macro-economic and diamond
market conditions improve.
In the meantime, various strategies to optimise open pit mining activities in both the Satellite and Main pits are continually being
investigated and implemented as appropriate. A steeper conventional concept for C6W in the Satellite pit, which will significantly
reduce the strip ratio, is currently under review.

Resource and Reserve Statement
Following the publication of Letšeng’s 2015 SAMREC Mineral Resource and Reserve Statement, efforts were focused on improving
confidence in the geological models and the predictability of the large +100 carat Type II diamonds, which contribute materially to
Letšeng’s value.
Initial petrography and microdiamond studies in the latter part of 2015 suggested that the geological complexity in both the Main and
Satellite pipes may have been greater than that reflected in the broader resource categories at the time. What set out as an exercise to
better understand the internal variability of the existing resource domains in the Main pipe (KMain, K6 and K4) and Satellite pipe (NVK
and SVK), transformed into a comprehensive drilling and resource development programme spanning eight years and culminating in a
new appreciation of the complexity within the Letšeng orebodies, as reflected in the current Resource and Reserve Statement.
The 2024 Mineral Resource and Reserve Statement was prepared in line with the Canadian Institute of Mining, Metallurgy and
Petroleum’s (CIM) Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines dated November 2019, and the
Definition Standards for Mineral Resources and Mineral Reserves published May 2014, and is reported in accordance with the Canadian
Securities Administrators’ National Instrument 43-101 Standards of Disclosure for Mineral Projects.
Letšeng’s 2024 Mineral Resource Statement is informed by a suite of geological studies that (i) enabled differentiation between the
various known and newly recognised kimberlite domains, (ii) delineated the internal boundaries between the kimberlite domains, and
(iii) characterised them in terms of their diamond populations, volumes, tonnages, grades and value.
The 2024 Resource and Reserve Statement and NI 43-101 Technical Report is based on an extensive drilling and resource development
programme that commenced in 2015 and was completed in 2023 and included the following workstreams:
• Three phases of additional diamond core drilling: 2017-2020 (31 drillholes, 8 386 metres), 2021-2022 (24 drillholes, 8 640 metres) and
2022-2023 (8 drillholes, 2 235 metres).
• Petrographic analysis and mineral chemistry conducted between 2015 and 2023 in both the Satellite and Main pipes.
• Microdiamond analysis: initial studies in late 2015 followed by more detailed studies in 2019-2020.
• Discrete sampling, production and updated sales data was analysed for diamonds recovered from the dominant domains within each
pipe.
• In-pit mapping data of internal and external domain contacts.
• 3D geological models for both the Satellite and Main pipes were updated.
• Updated Size Frequency Distributions (SFD) for each domain.
• As-built survey of the open pit topography as of 31 December 2023.
The Reserve Statement has been prepared on a Life of Mine plan including SC6W on current slope angles (refer to page 47). An
opportunity to optimise this plan with a steeper conventional concept is discussed below on page 48.

Long-term mine plan
Letšeng’s long-term mine plan has incorporated all relevant attributes of the 2024 Resource and Reserve Statement discussed above.
The previous long-term mine plan was predicated on SC5W being completed in 2024 at an extraction rate of 3.0 million tonnes of
Satellite ore per annum. The extraction rate of Satellite ore from the SC5W cutback has been revised down in 2024 to c.2.0 million
tonnes with the remaining c.0.9 million tonnes of ore from this cutback to be mined out by Q2 2025. Cost containment, the potentially
unsafe conditions created when mining above SC5W before ore extraction is complete, and the opportunity to finalise the study of a
steeper conventional concept for SC6W to avoid unnecessary waste stripping on the conventional slope angles, has necessitated that
the commencement of waste stripping in SC6W be pushed out, from Q1 2024 to Q3 2025.
In addition, the anticipated ore from SC6W has been reduced, as instantaneous triple and double benches on the kimberlite basalt
contact areas around the pipe had to be removed from the updated pit design. The strategy of transitioning from basalt to kimberlite
was revised in the 2024 mine plan to include flatter angles around the basalt/kimberlite contact areas. The revised strategy was in
response to the latest geological mapping results, which revealed the curvature and dip of the pipe contact not supporting the double
and triple benching previously planned along the pipe contact. Consequently, about 1.3 million tonnes of ore of the previous SC6W
mine plan can no longer be accessed safely.
During the annual review of the long-term mine plan in the first half of 2023, it was observed that the in-situ revenue per tonne for
certain ore domains in the Main pipe had decreased, impacting the economics of the final cutbacks in the Main pit (MC4). The latest pit
optimisation model indicated a smaller MC4 than in the previous long-term mine plan. MC4 West was therefore redesigned in line with
this outcome, which resulted in reduced waste required to be mined and an estimated 10.0 million tonnes of ore no longer being
economically viable to extract. The 2024 mine plan was updated to include the revised waste and ore volumes for MC4W, thereby
reducing the previously published mine plan by approximately two years from 2040 to 2038.
The long-term mine plan has also been updated using the latest resource models discussed above. For most of the ore domains, except
K2 (Main pipe) and NVK (Satellite pipe), the indicated and inferred resource interface levels were shallower than in the 2015 resource

models. This resulted in some ore that was included as indicated in the previous mine plan now being excluded in line with the mineral
reserves declaration rules. Pending possible further upgrade of the inferred resources in both the Main and Satellite pipes, the revised
final pit shell has been designed to include only indicated resources with minimal inferred resources being included. This has shortened
the updated life of mine plan by an additional two years, from 2038 to 2036/7. Refer to the updated long-term mine plan in the graph
below.
The updated long-term mine plan includes SC5W, MC4E, a smaller MC4W and SC6W (each based on current slope angles) and an
updated plant throughput rate to life of mine of 5.3 million tonnes per annum. Waste stripping of the SC6W cutback is currently
scheduled to commence in 2025 with ore estimated to be available from end 2030 at an extraction rate of 2.5 million ore tonnes per
annum thereafter.
The life of mine production profile is shown in the figure below:
Life of Mine optimisation projects
Steeper conventional pit concept in Satellite C6W
Slope steepening carried out at Letšeng in a safe and responsible way has had a significant positive effect on the economic value of
open pit mining by reducing the stripping ratio. An initiative to introduce a steeper conventional design in the basalt of SC6W cutback
commenced pit designs of a steeper slope concept with the final cutback commencing from within the current SC5W pit have been
completed. The slope design has been approved by independent slope design experts in Q4 2023 and the requisite support design
and costs are being analysed to fully evaluate the factor of safety, economics and overall feasibility of the concept. Results of this study
are expected to be completed by Q3 2024. In the event that we are able to safely execute the steeper conventional concept in SC6W,
with the benefit of significantly reduced waste, the above long-term mine plan adopted in our 2024 Reserve Statement will be amended
accordingly.
Upgrading inferred resource
The updated long-term mine plan shown in the graph above could be extended by an additional two years (c.12.5 million tonnes)
without any incremental stripping of waste by upgrading the inferred resource in the Main pipe to indicated resource. Once upgraded,
the ore could then confidently be included in the long-term mine plan with no incremental stripping of waste, given the flexibility that
has been incorporated in the current final pit design.
Ghaghoo
We remain committed to exiting the Ghaghoo Diamond Mine in Botswana, which has been on care and maintenance since March 2017.
In the absence of a sale, closure and/or handover options are being actively pursued and affected stakeholders have been widely
consulted.
The site is being well maintained in a safe and responsible manner. Employees on site have consistently demonstrated adherence to
safety protocols and environmental regulations, with no instances of activities causing any disturbance to the environment being
reported, and we are pleased to report that there were no LTIs recorded at Ghaghoo in 2023.
In preparation for possible closure or partial closure and handover to government, extensive site clean-up and partial rehabilitation
activities commenced in H1 2023. This has been carried out in a cost-effective manner and included the removal and sale of a significant
amount of scrap metal and other redundant infrastructure and materials. The salvage values received for these contributed significantly

to the cost of the clean-up project. At the end of 2023, a solar power solution was implemented to power the necessary camp and
reverse osmosis water plant requirements. The solar plant was fully commissioned from 1 January 2024 and has completely replaced the
existing diesel generator power supply. Securing long-term power supply for the Ghaghoo operation allows for the site to be handed
over without additional diesel generator associated costs, and also supports the immediate rehabilitation and decarbonisation
objectives of the Group.
OUR PLANS FOR 2024
We have several operational objectives for 2024. These include:
• Optimising and improving the long-term mine plan of Letšeng with particular focus on the SC6W cutback.
• Further enhancing operational efficiencies and reducing overall operating costs.
• Investing in appropriate renewable and/or alternative energy sources. Providing a consistent source of power for the mine operations
remains a challenge at Letšeng. In the meantime, the focus remains on reducing power consumption throughout the Group, and low
energy-usage alternatives continue to be investigated and implemented.
SUSTAINABILITY
Refer to our Sustainability Report 2023 available at www.gemdiamonds.com for full details of our sustainability strategy and
performance in 2023.
UN Sustainable Development Goals
The Group has committed to contribute to the global drive to realise the United Nations Sustainable Development Goals (UN SDGs)
and has developed an appropriate framework for meeting this commitment. The Group’s UN SDG framework aims, over a three-year
period (2023 – 2025), to self-assess current contributions and thereafter implement appropriate measures to advance the realisation of
the Group’s eight adopted UN SDGs. Following the first three-year cycle (2021 – 2023), an additional two SDGs were adopted in 2023,
being Zero Hunger and Climate Action.

Residue Storage Facility and Dam Management
Operational status of dams and residue storage facilities
We acknowledge the severe adverse impact poor Residue Storage Facility (RSF) (previously referred to as Tailings Storage Facilities
(TSF)) management can have on human lives, the natural environment and our business. To this end, Letšeng has reviewed all applicable
international standards, codes and guidelines related to responsible RSF management and aligned our Residue Management System
(RMS) to the Conformance Protocols on the Requirements of the Global Industry Standard on Tailings Management (GISTM) published
by the International Council on Mining and Metals (ICMM). The RMS is a comprehensive framework that integrates people, resources,
processes and practices related to RSF management to help the business achieve its performance objectives, manage risk and ensure
safe, responsible management of its RSFs. The RMS is aligned and integrated with other relevant site-level systems, such as the site-
wide environmental and social management system and systems related to water management.
Letšeng has two RSFs and one freshwater dam on site:
1. The Patising RSF, which is currently in use for the deposition of coarse and fine tailings from the treatment plants.
2. The Old RSF has reached capacity and is no longer used for any tailings deposition. Plans for concurrent rehabilitation are currently
being considered.
3. The Mothusi Dam, which is the mine’s freshwater supply source.
Letšeng’s RSFs and freshwater dam were constructed using the centre line and downstream tipping method, being a safer method of
construction than the “upstream” construction methods used in most recent dam failures reported in the mining industry. The RSFs and
freshwater dam are managed in accordance with the adopted industry best practices and governance structures. No areas of concern
have been noted at the established governance forums and the operational parameters are in line with the set targets. The condition of
the RSFs and all risk mitigation measures are continuously monitored and well managed. The appointed engineer of record (EoR) and
Independent Tailings Review Board (ITRB) have conducted their periodic and annual inspections of the respective facilities and have not
noted any issues or concerns related to the stability and management of these facilities. There were no incidents of compromised dam
or RSF integrity in 2023 or prior thereto.
We recognise that ensuring the integrity of our RSFs and freshwater storage facilities is non-negotiable and integral in exercising our
responsibility to safeguard our workforce, communities and environment to ensure business continuity. We remain focused and
proactive in managing our RSFs according to adopted international best practice. Retaining structures and embankments undergo

stringent safety monitoring in the form of inspections and audits, which are conducted both internally and externally at regular intervals
throughout the year. Stringent inspections and monitoring on a daily, weekly and monthly basis include surveying various factors such as
the densities of fines deposits, water levels, beach lengths and freeboard. Annual structural stability analysis is also conducted at our
RSFs, and an early-warning system, together with community training and awareness programmes, are used to ensure the emergency
readiness of communities that could be affected in the unlikely event of a failure. The nearest village is located 20km downstream from
the mine. The findings and recommendations stemming from these investigations and audits are reported quarterly to the Boards and
Sustainability subcommittees at both operational and Group level.
An external consultant was appointed to investigate the founding conditions of the RSFs, construct stratigraphic models for each of
those, and conduct a stability analysis followed by a review and update of the previous dam breach analysis that was conducted in 2020.
From the study results it was concluded that the stability of the RSFs at current height complies with the minimum safety requirements.
Based on the in-depth stability assessment conducted on the RSFs at final height, the overall stability exceeds requirements and
liquefaction risk is considered low (and largely inconsequential if it were to occur). The most credible mode of failure associated with a
far-reaching zone of influence is thus linked only to the escape of impounded water.
Refer to our Annual Report and Accounts 2022 available on our website at www.gemdiamonds.com for full details on our RSF
governance framework and assurance strategy.
Managing our environmental footprint
The Group has adopted detailed sustainability, environmental, climate change and water management policies that clearly set out our
adherence to best practice in managing our environmental footprints and associated impacts. During 2023, zero major or significant
environmental or stakeholder incidents were recorded, Letšeng received its seventh consecutive annual ISO 14001 (Environmental
Management) and 45001 (Occupational Health and Safety Management) certifications and the three-year TCFD adoption strategy was
successfully concluded.
In Q1 2023, the Group committed to a 30% reduction of its Scope 1 and 2 emissions by 2030, using 2021 as a baseline. The total 2023
carbon footprint for the Group was 110 198 tCO
2
e (2022: 112 827 tCO
2
e), 28% lower than our 2021 carbon emissions. This includes direct
carbon emissions (Scope 1), energy indirect carbon emissions (Scope 2) and material Scope 3 emissions.
The Group strives to minimise its environmental impacts and minimise the consumption of natural resources by working within our value
chain to identify and implement initiatives that will reduce operational costs and minimise environmental impacts. Our water
stewardship strategy is informed by nature-based solutions that offer synergies between ecosystem health and human well-being, while
ensuring adequate water supply for operational activities. In 2023 we commenced with the construction of a bioremediation treatment
plant to treat water predominantly leaching from our active mineral waste dump. This plant has a capacity to treat ~300 000 litres of
water per day and the first module was commissioned at the end of 2023, with the remaining five modules commissioned in Q1 2024.
Corporate Social Responsibility
Our social licence to operate is supported by regular engagement with all stakeholders, including government, local communities,
employees and other interested parties, to address challenges with mutually beneficial and sustainable solutions. As responsible
operators and social partners in our host countries, we endeavour to maintain healthy and constructive relationships with governments,
employees and our PACs.
During 2023, the Group CSRI programme mainly focused on small and medium enterprise development, education and basic
infrastructure provision. The Group invested US$0.4 million towards the following CSRI projects:
• Letšeng awarded four scholarships to young Basotho citizens (55 scholarships awarded since 2007).
• We expanded the egg production capacity at our Mokhotlong and Mapholaneng egg circle projects to help farmers meet increasing
demand.
• We assisted with the increase in milk production at our dairy project by donating 17 additional cows and a tractor to plant fodder in
their fields.
• We built classrooms for the Ntlholohetsane and Tšepong primary schools.
• We renovated classrooms at the Ha Moroke and Mapholaneng high schools.
Gem Diamonds endeavours to leave a positive legacy in the countries in which we operate through contributing to local economies,
maximising local employment and procurement opportunities, and developing sustainable CSRI projects. We take an integrated
approach to achieving this, and we understand how matters of sustainability, society and the environment are inextricably linked.

GOVERNANCE
How we govern climate-related risks and opportunities
Board
The Board, supported by the Sustainability and Audit Committees, is ultimately responsible for the governance of climate-related risks
and opportunities, and for ensuring that our decarbonisation strategy (to mitigate potential negative impacts on the climate) is
implemented in a manner that is in the best interest of the Group.
To ensure effective oversight, the Group has adopted the Governance structure set out below. The Board and relevant Committees
receive regular updates on climate change-related matters and, following the full adoption of the TCFD, on the monitoring and
managing of our climate-related exposure and the tracking of progress against our decarbonisation targets. The climate change-related
data and performance information presented to the Board and relevant Committees informed the 2023 reviews of the Group strategy,
risk management framework and annual budgets.

Oversight
Governance
Responsibility
Management
The Group COO has overall executive accountability for sustainability, including climate-related issues, decarbonisation and energy-
related matters. The COO acts upon the most material risks and opportunities to successfully transition business models for maximum
benefit lower-energy consumption and higher efficiencies leading to reduced costs and decarbonisation. The Group CFO holds overall
executive accountability for integrating climate-related issues into annual budgets, business plans, financial disclosures and risk
management.
Through the three-year TCFD adoption project, the Group has embedded the consideration of climate-related risks and opportunities
within the appropriate internal functions (i.e. enterprise risk management, communication and reporting, insurance, financial planning
and disclosure, project management, internal audit, engineering, mining and treatment) to bolster the integration of climate change,
energy and decarbonisation strategies throughout the business. Management reports to the Gem Diamonds and Letšeng Boards and
their respective Audit and Sustainability Committees, on a quarterly basis, on the identification and response to climate-related risks
and opportunities.
Climate education and training
Climate science is constantly evolving. As the Group navigates its transition to a low-carbon economy, it is imperative that knowledge,
understanding and skills in this field are both kept up to date and improved. Management is responsible for identifying and responding
to emerging climate-related risks and opportunities. An understanding of these risks and opportunities is imperative to ensure that
appropriate levels of mitigation are developed and responsibly elevated through established governance structures, as appropriate.
Gem Diamonds has adopted a bottom-up approach to embed energy reduction and decarbonisation awareness across the Group.
Education around climate change and decarbonisation continued throughout 2023, with a series of workshops and presentations held
to explain to employees the concept of carbon footprint and the importance of carbon reduction.

STRATEGY
The impacts of climate-related risks and opportunities on
our businesses, strategy and financial planning
Our Group strategy to sustainably maximise stakeholder value goes hand in hand with our commitment to be responsible stewards of
our natural resources. Our climate and decarbonisation work is integral to our objective to operate efficiently and further reduce costs.
We expect to realise additional reductions in our carbon footprint together with further cost savings through focused initiatives to
reduce energy consumption and improve efficiencies. Gem Diamonds identified three strategic priorities that underpin how the Group
creates value for our stakeholders. We believe that effective management of climate-related matters contributes to the Group’s
performance in line with these strategic priorities.

Decarbonisation strategy
We are aware of the importance of committing to practical, enforceable and realistic decarbonisation targets. The Group has therefore
committed to a 30% reduction of its Scope 1 and 2 emissions by 2030, using 2021 as a baseline. We will regularly communicate our progress
against this commitment, which is aligned with internal performance metrics, including specific key performance indicators and remuneration.
Our decarbonisation strategy considers the socio-economic environment in our host countries and the well-being of our workforce and
surrounding communities. We acknowledge the importance of a just transition from fossil fuel reliance, and we intend to target
decarbonisation projects that take into consideration economic, societal and climate impacts.
The Group adopted a bottom-up approach to identify decarbonisation risks and opportunities and consider potential implementation
pathways for resource-use efficiency and carbon-reduction initiatives. Since 2021, Gem Diamonds has commissioned independent
energy and carbon subject matter experts to identify opportunities to improve energy efficiency and reduce the energy use associated
with Scope 1 and 2 emissions. We continuously assess and implement initiatives to progressively reduce our overall demand for energy
and, where possible, switch to lower-carbon and renewable energy sources. Reducing the overall demand for energy means that
implementing renewable energy sources and offsetting residual emissions becomes as efficient and cost-effective as possible.

Our decarbonisation strategy targets two key levers for reduced carbon emissions within both Scope 1 and 2:
• reduce our energy use and associated carbon emissions by improving the efficiency of our processes and equipment; and
• replace our dependence on fossil fuel-based energy sources with lower-carbon and renewable energy sources.
Letšeng draws its power from the South African power grid, supplied by Eskom. A 2021 study by the Centre for Research on Energy and
Clean Air found Eskom to be the world’s most polluting company. This is as a result of Eskom’s 15 coal-fired power stations, which
produce 80% of the country’s power. Eskom-supplied grid electricity is currently the only grid power that Letšeng has access to and
accounts for all our Scope 2 emissions. As of 2023, no renewable or alternative electricity sources are available to Letšeng to replace the
existing grid-supplied electricity. Mobile (mining fleet and equipment) and stationary (diesel-powered generators) combustion activities
account for 98% of our Scope 1 emissions, emanating from the diesel consumed through these activities.
What we learnt How we responded
Scope 1 The extremely low temperatures at Letšeng eliminate the
possibility of biodiesel to replace traditional mineral diesel.
This is because biodiesel thickens in the fuel systems of the
mining fleet and equipment at low temperatures.
While we are actively reducing our diesel consumption,
we are assessing alternative energy sources for our
mining fleet and equipment that could potentially
replace traditional diesel combustion engines in the
future.
Frequent load shedding has increased the use of
generators at Letšeng. These energy interruptions are
potentially damaging and costly as machinery should be
shut down safely and not abruptly in mid-use. Restarting
machinery also consumes more power and increases the
risk of damaging equipment.
We ensure that load shedding schedules are integrated
into our production planning to facilitate an effective
changeover to generator power. In the short term, we
are assessing lower-carbon energy for our generators.
Scope 2 The remaining life of open pit mining at our Letšeng
operation impacts the feasibility of any capital-intensive
projects.
We are continually optimising the mine plan for
extended life and simultaneously assessing the
possibility of hybrid power solutions and partnerships to
bolster the viability of large-scale renewable energy
projects.
The Letšeng mine operates in a region that is protected as
a nesting zone for endangered vultures. As a result,
traditional turbine-driven wind power development is not
possible within a 40km radius of the mine.
We are assessing bird-friendly wind power technology
that poses no danger to endangered or other bird
species in the region.
The location-specific irradiance of the Letšeng mine
indicates that a maximum of 5.5 hours a day are available
for energy yield through solar photovoltaics.
We commissioned a study to assess the viability of solar
power as part of a hybrid model that includes other
renewable energy sources.
We have integrated energy efficiencies, alternative energy sources and decarbonisation into our overall business strategy, and
prioritised these as critical workstreams. In 2023, our Scope 1 and 2 carbon footprint comprised 48% direct Scope 1 emissions (2022:
49%) and 52% indirect Scope 2 emissions (2022: 51%). For more information on the decarbonisation initiatives implemented during
2023, refer to the Targets and Metrics section on page 58.

RISK MANAGEMENT
How we identify, assess and manage climate-related risks
Gem Diamonds has a robust risk management process and framework to identify, assess, manage and mitigate current and emerging
risks and uncertainties. Our risk management framework combines a top-down and bottom-up approach to ensure appropriate
governance and oversight. It ensures that all material risks are appropriately identified, assessed, mitigated and monitored. Risks are
assessed and prioritised in terms of potential impact, probability of occurrence and effectiveness of controls across short, medium and
long-term timeframes.
We have collaborated with experts in insurance, decarbonisation, energy and climate change to identify emerging risks and potential
opportunities for improvement or mitigation, with the aim of assessing our readiness for responding to these. Our collaboration with
external experts enabled us to bolster our organisational system readiness and plan appropriately for the mitigation of future risks to the
business.
• The Board has ultimate responsibility for climate-related risk
management.
• The Audit Committee regularly receives reports on risk, strategy and
governance processes related to climate change and the associated
financial disclosures.
• The Audit Committee has oversight of climate-related risks and
potential financial, strategic and business planning impacts, which are
presented to the Board during quarterly risk meetings.
• The Sustainability Committee oversees that appropriate systems are in
place to identify and manage climate-related Health, Safety, Security
and Environment (HSSE) impacts.
• The Sustainability Committee oversees energy and decarbonisation
risks and opportunities, and monitors performance against carbon and
water footprint parameters.
Top-down
approach –
Board

Committee
• Management assesses the materiality of climate-related risks identified
through the risk identification process.
• Based on this assessment, a risk management plan is developed and
presented in quarterly meetings to the Audit and Sustainability
Committees and, ultimately, to the Board for approval.
• Emerging and existing regulatory requirements related to climate
change issues are monitored and addressed by the Audit and
Sustainability Committees. The Group HSSE and Sustainability Manager
attends these meetings by invitation.
• Management assesses energy and decarbonisation risks and
opportunities. Progress against risk mitigation opportunity
improvement plans are presented to the Sustainability Committee.
• Gem Diamonds has established internal and external processes to
identify climate-related risks.
• Quarterly risk workshops for department heads provide management
oversight of climate-related risks. The outcomes of the risk workshops
inform updates to the Group risk register and mitigation measures to
be implemented. These are presented to the Board at the quarterly risk
review meetings.
• Approved risk management plans are implemented by management at
Group and operational level. This is monitored and managed through
quarterly technical reviews, management risk workshops, quarterly risk
reviews, and Board and Committee meetings.

Physical and transitional risk exposure assessments
In 2023, we expanded on the comprehensive physical and transition risk exposure assessments we conducted in 2021, determining the
materiality of potential impacts on financial performance and production. We took a science-based approach to identify potential
exposure events associated with our climate-related risks and materialisation, enabling us to better plan for their management,
mitigation and financial impact.
Climate-related transition risks are incorporated into our risk management framework. Our resilience to physical climate-related risks is
robust, and we continue to improve our understanding and materiality of the potential physical risks under various future scenarios.

TARGETS AND METRICS
The targets and metrics used to assess and manage
relevant climate-related risks and opportunities
The Group monitors various metrics to inform its assessment of climate-related risks and opportunities. We conduct semi-annual carbon
and water footprint assessments, which provide shorter-term monitoring of our progress against set goals and the associated
immediate risks and opportunities. This allows us to respond rapidly to climate and energy-related matters such as consumption rates,
carbon emission trends and opportunities to improve usage efficiencies.
The following metrics and trends are measured and monitored as part of our normal operations:
• Carbon footprint
• Water footprint
• Freshwater dam levels
• Precipitation patterns
• Energy consumption trends
• Environmental expenditure
• Land use and rehabilitation activities
For more information on our carbon emissions, including Scope 1, 2 and 3 emissions and other climate-related metrics, refer to our
Sustainability Report 2023 available at www.gemdiamonds.com.
Our carbon, energy and water footprints
Carbon
The Gem Diamonds' carbon footprint is calculated in accordance with the GHG Protocol Corporate Accounting and Reporting
Standard, an accounting tool developed by the World Resources Institute and the Business Council for Sustainable Development to
manage GHG emissions. The standard includes Intergovernmental Panel on Climate Change GHG inventory guidelines for specific
heating values, carbon content, densities and emission factors.
Our total 2023 carbon footprint for the Group was 110 198 tCO
2
e, 2% lower than 2022 (112 827 tCO
2
e). This includes direct carbon
emissions (Scope 1), energy indirect carbon emissions (Scope 2) and material Scope 3 emissions.
The reduction of Group-wide carbon emission, since 2021, has been driven by the reduction of our ore and waste profile as well as the
implementation of initiatives to reduce energy consumption, improve energy-use efficiencies and transition to renewable energy
sources. Mining optimisation initiatives implemented during 2021, such as reduced hauling distances, steeper slopes and reduced
mineral waste mining, were advanced further during 2023. Relooking at these initiatives to assess and implement further improvement
opportunities not only contributed to a reduced carbon footprint, but also mitigated the impact of significantly increased diesel usage
and associated cost to power the plants during the longer and more frequent periods of grid power load shedding experienced in 2023.
We implemented the following operational measures that have contributed to the reduction of our carbon footprint and associated
energy costs:
Reviewed the basic maintenance
processes and purchased a mobile
maintenance vehicle for the mining fleet
to reduce tramming in and out of the pits
Designed a priority-controlled electrical
load management system for Letšeng for
implementation in 2024
Transitioned the Ghaghoo operation
from diesel-powered generators to
renewable solar power
Further reduced our waste rock hauling
distances, resulting in a reduction of our
carbon emissions, diesel consumption
and associated costs
Relocated diesel depots to reduce the
distance mining equipment needs to travel
to refuel
Replaced all lighting infrastructure at
Letšeng with energy-efficient
technology
The above measures, and reduced ore and waste profiles, have resulted in a 41% reduction of mobile diesel consumption (the diesel
consumed by our mining fleet and support equipment) since 2021. As a result of the reduced diesel consumption, we also saw a 25%
reduction in our Scope 1 carbon emissions over the same two-year period.

While the Group has been working to decarbonise the Letšeng operation, our most material carbon emissions contributor, the reliability
of the South African electricity grid has deteriorated, with load shedding worsening to unprecedented levels during 2023. The South
African grid was affected by load shedding on 335 days in 2023, up from 205 days in 2022, 75 days in 2021 and 54 days in 2020. Letšeng
relies on diesel-powered generators to power the operation during periods of load shedding or other grid power outages. Since 2021,
there has been a 215% increase in generator hours and 245% increase in the volume of diesel consumed for generator power. The
increase in diesel consumption by the generators has been offset by the reduction in diesel consumption by the mining fleet and
support equipment as a consequence of lower volumes mined.

combination of load shedding and energy-efficiency initiatives implemented at Letšeng to reduce energy consumption.
The Group monitors intensity indicators to assess and appropriately respond to carbon emission changes. Although our emissions
intensity for tonnes mined (ore and waste) increased slightly in 2023 from 2022, this was directly related to the significant reduction in
waste tonnes mined being offset by a relatively smaller reduction in overall emissions. However, our intensity indicators for carats
recovered and ore tonnes treated showed a 22% and 9% improvement from 2021 to 2023.

The Group will continue to measure and report on our carbon footprint performance as we work towards our goal of reducing our
footprint by 30% by 2030, using 2021 as a base.
Energy
In 2023, as part of our ongoing efforts to reduce our energy consumption, associated emissions and operational costs, we implemented
the following initiatives:
• Diesel usage was reduced through route optimisation, reduced hauling distances, relocated support infrastructure, reduced idling of
fleet, improved maintenance programmes and improved driving behaviours.
• We replaced existing mine area, workshops and conveyor belt lighting with energy-saving LEDs, reducing lighting power
requirements by 70%, from 234kW to 68kW.
• A priority-controlled electrical load management system was designed for implementation in 2024, enabling low-priority power usage
to be curtailed during load shedding.
• Heating, used in office and accommodation buildings on site, was automated to relieve the pressure on generators during load
shedding.
Group-wide energy consumption (for Scope 1 and 2 activities) in 2023 was 217.7 million kWh (2022: 219.6 million kWh). 99% of Scope 1
and 2 energy consumption in 2023 is attributable to Letšeng, where our principal energy sources are grid electricity and diesel-powered
generators. The reduction in Scope 1 and 2 energy consumption resulted in an improvement of energy-use efficiencies for ore tonnes
treated (refer to the table below). This illustrates an improvement in energy consumption across the board, from mining to treatment to
site services. The increase in energy intensity for tonnes mined was primarily driven by the significant reduction in waste tonnes mined
as the actual energy consumption for both Scope 1 and 2 reduced by 1.9 million kWh in 2023 from 2022.

Water
Gem Diamonds acknowledges the impact climate change will have on reshaping the future of freshwater. Changing precipitation
patterns are shifting seasons and affecting the timing and quantity of freshwater recharge. The impact of unmitigated industry on water
quality will further exacerbate an already vulnerable global water supply system, and as a responsible mining company and good
corporate citizen, we have therefore integrated water stewardship into our business strategy.
Our water stewardship strategy is informed by nature-based solutions that offer synergies between ecosystem health and human well-
being, while ensuring adequate water supply for operational activities. At Letšeng, ongoing water analysis over the years has indicated
an increase in nitrates in our water. Elevated nitrate levels are often associated with mining activities but are also attributed to the
application of fertilizers, human and animal waste and other sources. Nitrates may also be naturally present as a result of soil nitrification
processes from the mineralisation and mobilisation of nitrate from natural soil or host rock lithologies. In 2014, in response to the
increase in nitrate levels, Letšeng commissioned a nitrate management study to find and implement solutions to prevent nitrate-infused
water leaving the lease area. The study was extensive, and the solutions put in place have been far-reaching and effective. An official
nitrate task team, which works in collaboration with the relevant government departments in Lesotho, was also established. Since the
commissioning of the nitrate management study, the operation has implemented the following solutions to protect and maintain water
quality:
• Commissioned a wetland construction and rehabilitation programme.
• Changed blasting practices and procedures to limit the volume of nitrates from explosives released into the environment.
• Partnered with water conservation experts to trial the feasibility of fertigation and bioremediation as treatment methods, and
conducted leach testing to better understand the management options.
Following the successful trial of a passive treatment technology with leading experts, iWater, the results from two pilot plants tested at
Letšeng indicated that bioremediation was an effective denitrification process for our unique operating environment. In 2023 we
commenced with the construction of a bioremediation treatment plant, with capacity to treat ~300 kilolitres of water per day. The first
module of this plant was commissioned at the end of 2023 and the remaining five modules were commissioned in February 2024.
In 2023, Letšeng completed the design of an artificial phytoremediation (plant-based filtration) wetland to be located downstream of the
bioremediation treatment facility. Wetlands have proven to effectively offset environmental impacts, contribute to rehabilitation of the
environment, increase biodiversity, and act as a natural source of water treatment, and we have previously successfully established a
wetland within the mine lease area to improve denitrification of the run-off water.
Refer to our detailed water stewardship case study in our Sustainability Report 2022 available at www.gemdiamonds.com for more
information on our approach.
We are very mindful of our PACs’ access to sufficient potable water. Letseng has, through its CSI department, provided access to clean
water and sanitation infrastructure to multiple villages in Lesotho to assist communities in dealing with the issue of coliform
contamination of surface water. This issue is not related to mining activities, but is rather a result of livestock fouling. At Ghaghoo, we
continue to provide potable water to the Gope Community, with a potable water storage facility situated at the nearby police camp.
In 2022 and 2023, Lesotho received significant rainfall, recharging our freshwater storage facility. The water currently held in the Mothusi
freshwater facility ensures adequate water supply, at current usage rates, for the next eight years. The lower treatment volumes in 2023
and the implementation of water stewardship initiatives resulted in a 30% decrease in our Group-wide net water usage and a 44%
decrease in water withdrawal.
The management of our response to more dynamic weather patterns will continue to evolve alongside our understanding of the
impacts of climate change.

BOARD LEADERSHIP AND GROUP PURPOSE
Effective Board
The Board comprises Directors with a broad range of appropriate expertise, knowledge and insights including extensive mining industry
experience (refer to page 179). The Board’s focus areas (refer to page 63) support the guidance of the Code by fostering the long-term
sustainability of the Group, creating and preserving stakeholder value and contributing to wider society.
The Board oversees, analyses and approves the annual strategy and business plan prepared by Executive Management. This year’s
review took place in November 2023 and assessed the ongoing relevance of the strategy against the current local and global context,
the potential impact of current and emerging risks (refer to page 21), and the appropriateness of the current business model (refer to
page 6) to achieve our strategic objectives.
Governance
Gem Diamonds Limited Annual Report and Accounts 2023
70

by reinforcing the purpose, values and goals.
The Board monitored strategic metrics to track culture, including:
• Training data.
• Diversity of the workforce and an appropriate diverse pipeline for succession planning.
• Recruitment, reward and promotion decisions.
• Whistleblowing, grievance and “speak-up” data.
• Board interaction with senior management and the workforce.
• Health and safety data.
Governance framework and Board resources
The Group’s corporate governance framework and processes provide effective oversight of the business to ensure long-term value
creation and benefit for all stakeholders. Strategy development and execution is supported by:
• Clear lines of accountability and responsibility.
• Linking the strategic priorities to KPIs that can be tracked to monitor delivery on the strategy.
• Regular feedback and sharing of information to inform timeous decisions.
• Engaging with key stakeholders to ensure their concerns and interests are included where relevant (refer to page 14).
• Maintaining an effective risk management framework (refer to page 21) aligned with the Group’s strategy and performance
objectives, and supported by comprehensive internal controls and regular assurance.
• Independent insight and knowledge from the non-Executive Directors.
Clear information flows are in place between the Board and Executive Management, and ample time is provided at Board meetings to
focus on strategy and key decisions. The information the Board receives allows for an appropriate level of detail to inform the
discussions, without being excessive. Where relevant, the person responsible for the report attends the Board meeting to provide
further information and give Directors the opportunity to gain deeper insights into the matter. Presentations by external experts in
relevant areas expose Directors and Executive Management to new perspectives.
Independent advice
The Directors have access to Executive Management and the advice and services of the Company Secretary. The Company Secretary is
accountable to the Board for compliance with all governance matters and assists with professional development as required.
All Directors, either independently or collectively, may take independent professional advice at the expense of the Company, in the
conduct of their duties, subject to prior consultation with and approval by the Chairperson or the Senior Independent non-Executive
Director.
Company Secretary
The Company Secretary is supported by outsourced company secretarial services provided by the law firm Shakespeare Martineau LLP.
This ensures all Company secretarial and governance issues are attended to and the Board is kept abreast of all compliance and best
practice matters throughout the year.

the UK Companies Act 2006 and rules made by the UK Listing Authority. Neither the insurance nor the indemnity provide cover in the

The Board recognises the importance of effective and proactive engagement with stakeholders. Pages 14 to 17 contain a detailed
analysis of stakeholder engagement during 2023.

The meeting addressed the formal resolutions in the notice of meeting, and shareholders were invited to submit questions in advance.
Voting on all resolutions was conducted by poll vote. The results of the resolutions were announced through the Regulatory News
Services and on the Gem Diamonds website.
In accordance with the Code, if any resolution put to shareholders receives over 20% votes against, the Board will seek to actively
engage with investors to understand their concerns and publish a report on the actions taken and any next steps within six months of
the meeting. Refer to page 15 for further details of such resolutions and engagements.
The 2024 AGM will be held on Wednesday, 5 June 2024. Details of the resolutions to be proposed at the AGM will be included in the

Employee policies and practices
Employee policies and involvement
The Group prioritises the health, safety and effective performance of employees, and maintains positive employee relations. The Group
encourages a direct relationship with open communication between employees and management. Mazvi Maharasoa, a non-Executive
Director, is the Board’s representative who engages with the broader workforce and provides direct feedback to the Board on the key
concerns raised. In 2022, the Employee Engagement Committee was established, which is chaired by Mazvi and holds several meetings
annually with employee representatives. The Chairperson of the Remuneration Committee attends each operational site meeting at
least once a year to discuss how executive remuneration aligns with the wider company pay policy.
Matters raised during these meetings are addressed at Board and management level, as appropriate. Employees are informed about
the Group’s performance and objectives through direct and ongoing communication with management as well as the Group’s website,
published information, the employee app, the circulation of press cuttings and Group announcements. Refer to page 15 for details on
matters raised in the current year.
Equal opportunity is a fundamental principle of Gem Diamonds, and the Group is committed to achieving equality irrespective of
gender, religion, race or marital status. Applications from people with disabilities are welcomed for positions they can adequately fill,
having regard for their abilities and aptitude. Where existing employees become disabled, it is the Group’s policy, where practical, to
provide continuing employment under normal terms and conditions, and to provide training, career development and promotion for
disabled employees wherever possible.
The Group aims to attract and retain excellent management and employees by creating an environment that incentivises top
performance. Guidelines and frameworks covering remuneration benefits, performance management, career development, succession
planning, recruitment, expatriate employment and the alignment of human resources management and policies are in place and
aligned with international best practice. Each operating unit manages its human resources requirements locally, within the Group’s
guidelines and frameworks.
The Modern Slavery Statement, in accordance with the Slavery Act, is updated and published on the Group website annually and can be
viewed here: https://www.gemdiamonds.com/pdf/modern-slavery.
Bribery Act
The Group has a zero-tolerance approach to acts of bribery and corruption involving any of its employees, third-party representatives or
associates. We uphold and comply with the requirements of the UK Bribery Act. The Group’s terms of business require all customers
and third parties with whom business is transacted to adopt the same zero-tolerance approach to bribery and corruption as
implemented by the Board. The Group anti-bribery and corruption policy was reviewed during the year, with no changes necessary.
Refer to the Audit Committee report on page 90.
Whistleblowing programme
Independently operated and confidential toll-free phone hotlines are in place in each country where the Group operates. Online
submissions through www.gemdiamonds.ethicpoints.com can also be made. Individuals can report any breach of the Group’s business
principles through these channels, including but not limited to bribery, breaches of ethics and fraud.
All whistleblowing incidents reported are referred by the Group Internal Auditor or Company Secretary to the relevant operations,
where they are fully investigated. The results of these investigations are reported to the Boards of local operations and the Audit
Committee. Group Internal Audit periodically reviews the design and effectiveness of the hotline and reports the results to the Audit
Committee.
Governance
Gem Diamonds Limited Annual Report and Accounts 2023

During the year, there were 11 new whistleblowing reports, of which nine were resolved by year end. The open matter from 2022 was
also resolved. The Board is satisfied that the whistleblowing programme is being used effectively by concerned individuals and that all
reports raised in 2023 were properly investigated and reported.
Data protection
The Group’s privacy policy can be found on its website at www.gemdiamonds.com/privacy.php. A dedicated email address is available
for any correspondence relating to data protection and privacy queries: dataprotection@gemdiamonds.com. This is reviewed by the
Chief Financial Officer.
No correspondence was received during the year.
DIVISION OF RESPONSIBILITIES
Board roles
The governance framework on page 67 sets out the primary role of the Board.
The Board meets regularly, covering strategic matters such as operational and financial performance, risk management and other critical
business concerns, and has a formal schedule of matters reserved for its decision. The agenda for each Board meeting includes
discussion, decision-making and sufficient time and appropriate resource allocation surrounding these matters.
While all Directors have equal responsibility in terms of the law for managing the Group’s affairs, Executive Management is responsible
for operating the business within the parameters set by the Board. This includes producing clear, accurate and timely information and
reports to equip the Board to monitor and assess the Group’s performance.
Financial and operational performance are reviewed at each Board meeting, and Directors receive regular updates on the Group’s
performance across a range of metrics. Regular reports presented to the Board include health and safety reports; CSI and stakeholder
matters reports; TCFD and climate-related risk reports; risk management reports; residue storage facility integrity reports; operations
reviews; sales and marketing reports; half-year and full-year financial results; employee surveys and investor relations updates. Executive
Management draws on the expertise and experience of the non-Executive Directors.
Directors are encouraged to express their views freely and, where they have concerns about the running of the Group or a proposed
course of action, they may ask that these be recorded in the minutes where appropriate. No such concerns were raised during 2023.
Chairperson and Chief Executive Officer
The respective responsibilities of the Chairperson and the Chief Executive Officer are clearly defined and separate, ensuring a clear
division of responsibilities between the leadership of the Board and the executive leadership of the Group’s business. The Chairperson
is responsible for creating the conditions for the effective working of the Board. The Chief Executive Officer is responsible for the
leadership, operations and management of the Group within the strategy and business plan agreed by the Board. Their individual
responsibilities, together with the responsibilities of the Senior Independent Director and non-Executive Directors, align with the
requirements of the Code and are detailed below.

Independence
Non-Executive Directors are required to be independent in character and judgement. In applying the independence test, the Board
considers relationships with Executive Management, major shareholders, subsidiary and associated companies and other parties with
whom the Group transacts business against predetermined materiality thresholds.
The Board considers the majority of the non-Executive Directors, Harry Kenyon-Slaney, Michael Lynch-Bell, Rosalind Kainyah and Mike
Brown, to be independent in accordance with the Code. Mazvi Maharasoa adds extensive value to the Board; however, under the
criteria of the Code, she cannot be considered independent due to her previous role at Letšeng Diamonds.
The letters of appointment for the non-Executive Directors and the contracts of the Executive Directors are available for inspection at
the place of business of Gem Diamonds in London.
External commitments and conflicts of interest
External commitments
External commitments are detailed in the Directors’ CVs on page 179.
Conflicts of interest
The UK Companies Act (the Act) requires Directors to avoid any situation where they may have a direct or indirect interest that conflicts,
or may conflict, with the Group’s interests, unless approved by the non-interested Directors. In accordance with this Act, the Group
operates a procedure, which was reviewed with no changes by the Board in March 2024, to ensure the disclosure of conflicts and, if
appropriate, the consideration and authorisation of them by non-conflicted Directors. The Board maintains a register of “conflicts of
interest” that it reviews annually (most recently in March 2024). The Group voluntarily complies with this requirement.
Dealings in shares and the UK market abuse regime
Gem Diamonds’ share dealing policy and reporting procedures are in line with the UK Market Abuse Regulations implemented in July
2016 and updated in June 2022. The policy is due for review again in 2024.
Related-party transactions
Other than those disclosed in Note 24 of the financial statements, the Company did not have any transactions with, nor did it make
loans to, related parties during the period in which any Director had any interest.

COMPOSITION, SUCCESSION AND EVALUATION
Board Selection and Appointment Policy
The Board’s formal Selection and Appointment Policy ensures that the procedure for appointing new Directors is formal, rigorous and
transparent, and that appointments are made on merit against objective criteria. The Nominations Committee further considers
diversity (of gender, social and ethnic background), cognitive and personal strengths and specialist skill sets when reviewing
appointments. Further details are in the Nominations Committee report on page 83.
There were no changes to the Board or Board Committees during 2023.
Re-election
The Nominations Committee’s report is set out on page 83. The Articles of Association (82) provide that a third of Directors retire
annually by rotation and, if eligible, offer themselves for re-election. However, in accordance with the Code, all the Directors retire at the
AGM and, subject to being eligible, offer themselves for re-election. Details of the Directors’ service contracts are included on pages
100 and 102.
The Nominations Committee has considered and concluded that the Board has demonstrated commitment to its role. The Committee
is also satisfied that the collective skills, experience, background and knowledge of the Directors enable the Board and its Committees
to conduct their respective duties and responsibilities effectively.
Board expertise, experience and knowledge
The Board undergoes an annual review of the composition and chairmanship of its primary committees, namely the Audit, Nominations,
Sustainability and Remuneration Committees. The Company adheres to the Code’s requirement that there should be a balance of
Executive and non-Executive Directors so that no individual or group can dominate the Board’s decision-making.
As a mining company, the efficiency of the day-to-day operations, in both the medium and long term, is essential to achieving
shareholder value. Knowledge of the diamond industry is critical to developing new business opportunities and overseeing the Group’s
sales and marketing strategies. Knowledge of financial markets is also necessary to fulfil the Group’s strategy.
The biographies, which can be found on page 179, provide more information on each Director’s competencies. All Directors allow
sufficient time to the Group to fulfil their responsibilities effectively.
The non-Executive Directors have varied experience, competencies and unique perspectives to bring to bear on matters of strategy,
performance and resources that are critical to the Group’s ongoing success.

Diversity
The Board recognises the importance of increasing diversity, including gender and ethnic diversity, in the boardroom.
The Group supports diversity at all levels. The Diversity, Equity and Inclusion (DE&I) Policy covers both Board diversity and the approach
across the Group. The objectives of the Policy are to create an inclusive organisation, dedicated to encouraging a supportive and
inclusive culture among the whole workforce and committed to the provision of equal opportunities to anyone through recruitment,
development and promotion of employees, and the proactive tackling and elimination of any form of discrimination. It also endorses
the principle that the workforce at each location should reflect, as far as is reasonably possible, the community within which it operates.
The Policy is reviewed annually, and management monitors implementation of the Policy through the review of any related
whistleblowing matters as well and any employee grievances submitted through regular Human Resources channels.
Over time, the Board has improved its diversity from a position of no female and ethnic minority in 2018 to 29% female and ethnic
minority on the Board in 2023. The number of females in senior management across the Group increased to 43% in 2023 (2022: 38%).
99% of the total Group workforce are Lesotho nationals and 23% of the total workforce is female. Information on gender-based
employment can be found in our Sustainability Report 2023 available at www.gemdiamonds.com.
Due to the size of the Group, the Board consists of only seven members. During the year, no movement took place in Board
appointments and/or terminations, which posed challenges in increasing diversity on the Board. These challenges will continue into the
next reporting period as it is unlikely that requisite board movement will take place.
Data to obtain diversity statistics is collated through the use of Human Resources and Payroll reporting systems. Individuals are required
to submit data on their gender and ethnic status as part of onboarding processes within the Group. Currently, questions to obtain
gender and ethnicity status are straightforward and open-ended, simply requiring information on gender and race. These questions will
be amended from 2024 going forward to specify the categories indicated in the tables below.

Succession planning at Board and Senior Management level includes a review of skills, experience and diversity, and consideration is
given to all these areas when considering future appointments. Succession planning is a priority across the Group, with a focus on the
development of women and ethnic minorities into leading roles, which drives a diverse pipeline of talent.
Further detail on the Group framework on succession planning can be found in the Nominations Committee report on page 83.
Training and induction
A formal and bespoke induction is provided to new Directors on joining the Board. This includes meetings with management and
access to external auditors, and covers the Board Committees they join. In addition, ongoing support and resources are extended to
Directors to refresh their skills, knowledge and familiarity with the Group. Professional development and training are provided through
the following:
• Regular updates on changes (actual and proposed) in laws and regulations affecting the Group or its business.
• Planning, including site visits, to ensure Directors are familiar with Group operations, including its commitment to and application of
the Group’s corporate and social responsibility policies.
• Creating opportunities for professional and skills training, such as Committee chairmanship.
• Appropriate Board presentations and formal professional seminars.
Site visits
Visiting the Group’s operations and interacting with senior management and employees is an integral part of the Directors’ ongoing
knowledge of the business. In February 2023, the Board undertook a Letšeng site visit which was attended by five of the seven Board
members, including four non-Executive Directors and one Executive Director. In addition, Mike Brown visited Letšeng three more times.
The Executive Directors, Clifford Elphick and Michael Michael, visited the Letšeng mine site and the Maseru office in Lesotho a number
of times, and were accompanied by Michael Lynch-Bell on a visit to the Antwerp office.
Annual Board evaluation
As per the Code, the Board must undertake a formal and rigorous annual evaluation of its own performance and that of its Committees
and individual Directors. In 2023, an internal evaluation was conducted in Q4 2023, which was facilitated by Shakespeare Martineau LLP.
The review was carried out by questionnaire completed by each of the Directors.
The findings were consolidated into a report which, along with recommendations, was circulated to all Directors and discussed at the
November Board meeting. The overall findings from the evaluation were positive, with a number of recommendations made to consider
optimisation of the current operations, expansion and/or growth opportunities, implementing an individual performance feedback
mechanism between the Chairperson and other members of the Board, and Board visibility to shareholders and other stakeholders.
In 2024, the Board and Committees will implement the recommendations from the evaluation and monitor progress against these over
the following months.
The recommendations of the 2022 external Board effectiveness review, conducted by Ceradas, were implemented during the year.
AUDIT, RISK AND INTERNAL CONTROL
Financial reporting
The Board is conscious of its responsibility to present a fair, balanced and understandable assessment of the Group’s position and
prospects, and is satisfied that the Strategic Report from page 2 meets this obligation. The Responsibility Statement of the Directors in
respect of the Annual Report and Accounts 2023 is set out on page 1.
Financial reporting to the Board is regularly modified and improved to cater for evolving circumstances. The Group’s comprehensive
planning and financial reporting procedures include detailed operational business plans for the coming year and a three-year rolling
plan, and sustainability matters including climate-related risks and opportunities. The Board reviews and approves the Group’s annual
business plan, which is prepared in co-operation with all Group functions based on specified economic and sustainability assumptions.

Performance is monitored and relevant action taken throughout the year through monthly reporting of KPIs and updated forecasts for
the year, together with information on key risk areas.
In addition, routine management reports, including results to date and updated forecasts for the year, are prepared and presented to
the Board. Detailed consolidated management accounts, as well as an executive summary, are circulated prior to each scheduled Board
meeting. Between Board meetings, summary update reports covering matters such as operational performance, sustainability, sales
results, cash flow and progress on strategic matters are circulated to Board members and senior executives.
External auditor
A principle of the Code is that the Board establish formal and transparent arrangements for considering the application of financial
reporting and internal control principles and for maintaining an appropriate relationship with the Group’s external auditor, EY SA. These
responsibilities are delegated to and discharged by the Audit Committee.
The lead audit partner is based in Johannesburg, South Africa. Further information regarding the appointment of EY SA is detailed in
the Audit Committee report on page 90.
As required under section 418 of the Companies Act, 2006, to which the Directors have voluntarily elected to conform, each Director
confirms that to the best of their knowledge and belief, there is no information relevant to the preparation of the Auditor’s Report of
which the Company’s auditor is unaware, and the Directors have taken all reasonable steps to make themselves aware of any relevant
audit information and establish that the Company’s auditor is aware of that information.
Tender process for external auditor for 2024
In the Annual Report and Accounts 2022, the Group disclosed the decision to commence a tender process to find a suitable external
auditor to replace EY SA following its rotation after completion of the 31 December 2023 audit. The overall objective of the audit tender
was to select an appropriate audit firm in terms of quality and within a reasonable price range for the size of the Group. To ensure a
transparent and robust evaluation and selection process, the tender was led by the Chief Financial Officer (CFO) and Group Financial
Controller (GFC), with the Audit Committee overseeing the process.
Selection criteria
Four mid-tier audit firms were invited to submit their proposals. In order to be successful in the audit tender, the participants were
assessed on certain minimum requirements such as willingness to bid, footprint of firm in the Group’s subsidiaries’ jurisdictions, audit
firm and auditor independence and price range. In addition, a number of selection criteria were applied:
• Technical criteria including the proposed audit plan, audit quality, structure of audit, innovative tools and transition plan.
• Team quality including lead partner and team, industry knowledge, access to specialists and mitigation of frequent team changes.
• Resources and organisation including representation in industry and conflict resolution mechanism in the audit firm.
The firms were ranked against each other after each step in the tender process taking the above into consideration.
Request for proposal
In July 2023 the request for proposal was issued to the audit firms invited to the tender. Relevant information on the Group, its structure,
activities and policies were shared with each of the firms through an electronic data room that was accessible during the tender period.
In this period a structured Q&A process was in place where responses to clarification questions and additional information requests
were shared with all participating firms through the electronic data room.
Engagement sessions and site visits
Each of the participants visited the Letšeng mine in Lesotho and the sales and marketing office in Antwerp, accompanied by the CFO. A
series of engagement sessions were set up following both site visits to allow the participating firms to better understand the business
and discuss certain subject matter areas in greater depth with the CFO and GFC.
Evaluation
The final proposals submitted were compliant with the minimum requirements set, and all bids qualified and were assessed for the
evaluation against the selection criteria. The CFO, GFC and Letšeng Head of Finance reviewed each of the proposals and sought
additional clarifications from the audit firms through a further structured Q&A.
Each of the participating firms provided a final presentation of their proposal to the CFO, the GFC, the Letšeng Head of Finance and
the Audit Committee in September.
In October, the Audit Committee reviewed the evaluation conducted and concluded it was robust and that RSM UK was the preferred
firm to conduct the Group audit engagement for the 2024 financial period. The Committee considered the transition arrangements from
EY SA and concluded there were no significant risks. The Committee also noted that the CFO and Director, Michael Michael, previously
held employment with RSM Betty & Dickson South Africa some 15 years ago. The Committee concluded that in line with UK and SA
regulatory guidance this was not deemed a conflict of interest given the time gap, and the Committee had observed that Michael
Michael had acted independently during the process.
During its November meeting, the Audit Committee considered the process followed and results of the tender and agreed to
recommend to the Board that it would propose RSM UK for appointment as the external auditors of the Group at the 2024 Annual
General Meeting (AGM) for the financial year 2024. A resolution to this effect will be included in the 2024 Notice of AGM.

Internal audit
The Group Internal Audit function, as an independent assurance provider, is a fundamental component of the overall process by which
the Audit Committee and the Board obtain the required assurance that risks are being effectively managed and controlled and the
Group’s control environment is adequate and effective.
Our in-house Internal Audit function is supplemented by external industry experts when required. The Group Internal Audit function
reports directly to the Audit Committee and is responsible for co-ordinating the Group’s risk-based audit approach and evaluating its
effectiveness. It contributes to the improvement of the risk management process, control environment and governance systems. Various
ad hoc assignments are also performed during the year at the request of management.
The risk-based audit plan, approved by the Audit Committee, covers all operating units, focusing on the principal risks. It involves
discussions with management on the risks identified in the subsidiaries’ and Group risk registers, emerging risks, operational changes
and capital projects. Findings and agreed actions are reported to management and the Audit Committee.
Review of the Annual Report and Accounts 2023
The Board, supported by the Audit Committee, is responsible for ensuring the integrity and completeness of the Group’s Annual Report
and Accounts and Half-Year Report. The Board reviews the reports and applies its collective mind to their preparation and presentation
to ensure they provide a fair, transparent, balanced, understandable and appropriate representation of the Group’s performance,
strategy and material risks.
Internal financial controls
The Board is responsible for the Group’s overall approach to risk management and internal control, which is embedded in all key
operations. In accordance with the Guidance on Risk Management, Internal Control and Related Financial and Business Reporting
published by the FRC in September 2014, the Board has defined the processes adopted for its ongoing monitoring and assessment and
relies on reviews undertaken by the Audit Committee throughout the year. In addition, regular management reporting and a balanced
assessment of key risks and controls is an important component of Board assurance.
The internal control system aims to manage the business risks that significantly threaten the Group’s achievement of its business and
strategic objectives, with a view to enhance the value of shareholders’ investments and safeguard assets. The internal control systems
are designed to manage rather than eliminate risk, to achieve business objectives, and to provide reasonable, but not absolute,
assurance that the Group’s business objectives will be achieved within the Board-approved risk tolerance levels. The system of internal
control includes the controls over compliance with regulatory and legal requirements.
In 2023, the Directors reviewed the effectiveness of the system of internal control. For the review, the Audit Committee considered
reports dealing with Internal Audit plans and outcomes, as well as risk logs and management representations. A full report of the work
carried out by the Audit Committee on behalf of the Board is set out in the Audit Committee report on page 90.
Investment appraisal
Capital expenditure is managed through a budgetary process and authorisation levels. For expenditure beyond specific levels, detailed
written proposals are submitted to the Board. The approval procedure for investments includes funding options and a detailed
calculation of return based on current assumptions that are consistent with those included in management reports.
Post-investment reviews are conducted after the project is complete and, for material projects, Steering Committees are established to
monitor the progress against the approved plan. Details regarding the Group’s capital expenditure decisions during 2023 are available
in the CFO’s Review on page 34.
Commercial, legal and financial due diligence are carried out, using external consultants as appropriate, in respect of acquisitions and
disposals.
Risk management
Risks are monitored continually and formally reviewed quarterly. A comprehensive report of the Group’s principal and emerging risks
and how these are managed and/or mitigated can be found on pages 21 to 26 of the Strategic Report.
The Group’s operations perform regular risk assessment reviews and maintain risk registers. Objectives in the business plan are aligned
with risks, and a summary of the key risks, related internal controls, accountabilities and further mitigating actions are tabled and
approved by the Board. The Sustainability Committee provides assurance that sustainability-related risks, including health, safety,
environmental and climate-related risks, are monitored and managed appropriately. The Audit Committee and the Board, where
appropriate, are kept informed on progress against the plans and any significant changes in order to review the risk profile. This enables
the relevant management and non-Executive Directors to holistically review the risk, mitigate it and implement controls as necessary.
The Board reviews risks and risk management at a stand-alone quarterly risk review meeting that allows enough time to fully explore
risks and test management’s scenarios and plans. During these meetings, the Board reviews the risk register, interrogates the most
critical risks in detail and challenges mitigation plans with management.

REMUNERATION
Linking remuneration with purpose and strategy
The Remuneration Policy links executive remuneration to the underlying health and performance of the Group through relevant social
and environmental indicators of performance. The financial and non-financial KPIs used to measure performance align with our strategy,
which in turn supports the Group’s purpose to produce the best diamonds, in the best way, leaving a lasting legacy.
Remuneration Policy review
Directors’ remuneration
While the Board is ultimately responsible for Directors’ remuneration, the Remuneration Committee, consisting of independent non-
Executive Directors, determines the remuneration and conditions of employment of Executive Directors, as well as the Chairperson. The
current remuneration policy was adopted at the AGM in 2021, and June 2024 will mark the third anniversary of its adoption. A proposed
2024 remuneration policy will be submitted to shareholders at the 2024 AGM. The updated policy will become effective from that date,
if approved. The details of the Directors’ Remuneration Policy and all Directors’ remuneration are provided in the report on
remuneration on pages 94 to 113.
Performance outcomes in 2023
No adjustments were made to performance conditions set at the beginning of the year, and the formulaic Gem Diamonds Incentive
Plan (GDIP) outcome for the business scorecard was 35.5% of the maximum of 85%. The Remuneration Committee noted
management’s proposal to forego the cash element of the GDIP and to restrict the deferred shares element to more closely align with
the shareholder experience over 2023. The Committee agreed that only the deferred shares element would be awarded, and that the
share price to be used to determine the number of shares under the deferred GDIP award, which is to be granted in 2024 after the
release of the 2023 annual results, would be 25 GB pence, rather than the prevailing share price of c.10 GB pence at the meeting when
the Committee reviewed the GDIP outcome. This will have the effect of reducing the number of shares granted by c.59%, which also
implies a lower aggregate bonus for Executive Directors than that paid in 2022.
The GDIP business scorecard is shown on page 98.
Strategic targets
The 2023 GDIP rewards performance in the ratio of 15% on personal factors and 85% on business performance. This 85% business
weighting aligns with the strategic focus areas:
• Preparing for Our Future (10%)
• Extracting Maximum Value from Our Operations (55%)
• Working Responsibly and Maintaining our Social Licence (20%)
More information on the GDIP scorecard is available on page 98.

NOMINATIONS COMMITTEE
Harry Kenyon-Slaney
Non-Executive Chairperson
The role of the Committee is to:
• Lead and ensure a formal, rigorous and transparent procedure for the appointment of
new Directors to the Board.
• Assist the Board in ensuring its composition is regularly reviewed and refreshed,
considering the length of service of the Board as a whole, so it is effective and able to
operate in the best interests of shareholders.
• Ensure plans are in place for orderly succession to positions on the Board and the
Executive Committee.
• Oversee the development of a diverse pipeline for succession.
• Work and liaise with other Board Committees as appropriate, including the
Remuneration Committee, in respect of any remuneration package to be offered to any
new appointment of the Board.
Membership as at 31 December 2023:
• H Kenyon-Slaney
• M Brown
• M Lynch-Bell
Other attendees:
• C Elphick
• Secretary (Shakespeare Martineau LLP)
The Nominations Committee comprises three non-Executive Directors. The Committee’s terms of reference provides for a formal and
transparent procedure for the Committee to follow in executing its responsibilities. The terms of reference is reviewed annually, and
subsequently reviewed and approved by the Board, to ensure it continues to be fit for purpose and in line with best practice and
governance principles. The last review was performed in June 2023 to ensure it was compliant with the Code.
The Committee continued to assess the Board’s composition, evaluate the composition of the various Committees, and monitor
developments in corporate governance to ensure the Group remains at the forefront of good governance practices.
The Committee initiated an internal Board evaluation in October 2023 and the outcomes were discussed at the November 2023 Board
meeting. Following the extensive external Board evaluation conducted in March 2023 by Ceradas, the October 2023 recommendations
were minor and mainly administrative in nature. A summary of the evaluation approach and recommendations can be found on page 79.

Board composition
The composition, skills and independence of the Board remained key topics for the Committee during the
year. The objective of the Committee is to ensure that the Board retains a balanced composition and that all
members have the necessary skills and experience to contribute actively to the ongoing success of the
business.
In line with the UK Corporate Governance Code, the Committee assessed the independence of all non-
Executive Directors. This involved a review of both the external appointments held by each Director and of
any potential or actual conflicts of interest recorded. The Committee noted the external appointments held
by Board members, which were considered to be in accordance with the parameters of the Code and to have
no effect on their current duties to the Board. One non-Executive Director, Mazvi Maharasoa, is not deemed
“independent” in accordance with the Code. However, as with other non-Executive Directors, her extensive
experience of the mining industry, and particularly the regional context within which the Group operates, is
regarded as invaluable. All non-Executive Directors constructively challenge and scrutinise matters that come
before the Board and, after careful consideration, the Committee and the Board were satisfied that Mazvi
Maharasoa demonstrates the qualities of independence in carrying out her duties. All Board members were
recommended for re-election and were re-elected by the shareholders at the 2023 AGM.
Succession planning
The Committee maintains a proactive approach to succession planning and regularly reviews succession
planning across the organisation through a succession framework. This ensures candidates have been
identified to fill key roles in both planned and emergency situations and that appropriate development plans
are in place. The competencies and experience required in the boardroom were regularly assessed as part of
the succession planning process, and the Committee will continue to review the need to secure any particular
or specific skills.
During the year, the Committee oversaw the retirement of Glenn Turner, the Chief Legal Officer and
Company Secretary, and the subsequent appointment of Kiki Constantopoulos to the position of Company
Secretary.
The Committee’s succession planning review extends from senior management to the next level of
management, considering emerging talent and key roles with a particular focus on maintaining momentum
on diversity. Development plans for potential successors were progressed during the year.
Diversity
There remains a commitment to diversity in the boardroom, just as the Company is committed to equal
opportunities at all levels within the organisation. The Committee continued to be supportive of this objective
during the year. Appointments and succession planning focused on ensuring gender and ethnic diversity, as
well as ensuring that a wide range of experience, backgrounds, perspectives and skills were available to
facilitate effective decision-making.
The Committee reviewed the Group’s Diversity and Equality Policy and determined that it remained fit for
purpose.
During the year the Committee expanded its remit to review diversity across the Group to include all levels
below senior management.
Further detail on the Group's diversity, equality and inclusion approach can be found on page 78.
Board effectiveness
The Committee considered the 2022 external Board evaluation outcomes. The overall findings from the
evaluation were positive and the recommendations were implemented during 2023.
An internal evaluation was conducted in October 2023, which was facilitated by Shakespeare Martineau LLP.
The details are discussed on page 79.
The findings were consolidated into a report which, along with recommendations, was circulated to all
Directors and discussed at the March 2024 Board meeting. The Committee will monitor progress on the
implementation of the recommendations during the coming year.
The Board evaluation process reviews the current skills and experience of the members of the Board, as well
as its composition and structure. This process enables the Committee to identify what knowledge and
competencies are needed for the business in the future, and it therefore supports the search process for
future Board members. It further provides assurance that the measured skills remain fit for purpose and
support the Group strategy.
Committee membership
The Committee continued to evaluate the composition of the various Board Committees to ensure they had
the requisite skills and experience to perform effectively. It found that the Committees were appropriately
comprised and no changes to membership were proposed for 2023. All Board Committees are compliant with
the provisions of the Code.

to enable management to steer the Group in an increasingly volatile and fast-paced environment, while
always promoting exemplary governance practices in the boardroom.
• Continue to monitor alignment of talent and succession planning throughout the organisation to the needs
of the business and to the Group’s long-term strategy. Development plans for potential successors will
continue to be progressed during the coming year.
• Review its succession plans to address Board composition and diversity targets.
• Monitor progress on the implementation of the recommendations of the 2023 internal Board evaluation.
• Conduct a Board evaluation and continue to hone Board skills, experience and operational effectiveness to

External auditor and audit effectiveness
During the year, the Committee considered the effectiveness, objectivity, skills, capacity and independence of
EY SA (our external auditor), considering all current ethical guidelines, and was satisfied that all criteria were
met. The 2022 auditor’s fee was approved and the 2023 fee was considered as part of this process.
In advance of the 2023 audit, the Committee reviewed and assessed the appropriateness of the external
auditor’s plan, audit strategy, scoping, materiality and audit risks. The significant areas of audit focus
identified by the external auditors to be addressed during the course of the audit were primarily impairment
of property, plant and equipment and goodwill, revenue recognition, deferred waste stripping calculation,
taxation, the insourcing of the mining activities and early termination of the mining contract, inventory, bank
facilities, rehabilitation provisions, share-based payments and the prospects of Ghaghoo. The key audit
matter during the year was the goodwill impairment as mentioned in the Independent Auditor’s Report on
page 120. The Committee challenged the assumptions and judgements used in the impairment model. The
Committee was satisfied with the robust process followed by management and was satisfied that no further
work was necessary. The Committee was satisfied that all material audit risks were covered within the auditor’s
scope. The Committee assessed the materiality level applied as appropriate to identify relevant audit risks.
Following the audit, EY SA presented its findings to the Committee and the Committee met with the audit
partner without members of management being present. The audit partner also met separately with the
Committee Chairperson to discuss key audit findings, judgements and estimates. This provided an
opportunity to assess the audit work performed, understand how management’s assessments had been
challenged and assess the quality of conclusions drawn. The Committee also made enquiries of senior
management to obtain its feedback on the audit process and considered this feedback in its assessment.
In line with the Code and the duty of the Committee to assess the effectiveness of the audit process, the
Committee assessed the effectiveness of the current audit process, which remained largely unchanged, and
assessed whether the areas identified in the 2021 survey had been appropriately addressed during the 2022
audit. The Committee noted some minor improvements raised, but was satisfied that the audit strategy was
appropriate for the Group’s activities and addressed the risks the business faced, including factors such as
independence, materiality, the auditor’s risk assessment versus the Committee’s own risk assessment, and the
extent of the Group auditor’s participation in the subsidiary component audits.
Auditor appointment and independence and tender process for new external auditor selection
The Committee remained satisfied with the performance of EY SA and recommended its reappointment to
the Board for the 2023 financial year end results.
The provision of any non-audit service requires Committee pre-approval and is subject to careful
consideration, focused on the extent to which provision of such non-audit services may impact the
independence or perceived independence of the auditor. The fees for non-audit services amounted to
US$6 678. This was against the external audit fee of US$488 902, representing 1.4% of external audit fees.
In 2022, the Committee was made aware that EY SA will step down as the auditor for the 2024 financial year
end as a result of mandatory firm rotation rules applicable to South African auditors. During the year,
management completed its tender process for the selection of the new external audit firm, which is subject to
shareholder approval at the 2024 AGM. The Committee was satisfied with the process followed by
management and the recommendation made to the Board. Refer to page 80 for further details on the tender
process.
Anti-bribery and corruption
The Committee reviewed its Anti-bribery and corruption policy and concluded that it was adequate and no
further updates were required. There were no known or identified incidents of bribery during the year, and
the Committee is satisfied that the policy remains robust regarding compliance and diligence procedures.
Acting on whistleblowing
The Committee reviewed and monitored the actions and progress of all the whistleblowing reports that arose.
The whistleblowing line is an important tool to promote and encourage transparency and identify potential
areas of irregularities within the Group. During the year, 11 reports were received through the whistleblowing
line and 10 reports were closed, including one that was carried over from 2022. Two reports remained under
investigation at year end. The Committee approved the Group’s Fraud and Whistleblowing Policy, which
remained unchanged from the previous year’s review. There were no instances of fraud reported through the
whistleblowing line.

Monitoring internal audit
The Committee reviewed the principal matters reported by the Group Internal Auditor, based on its strategic
and risk-based audit plan, and continued to monitor management’s responsiveness to the findings and
recommendations of the Internal Auditor. The 2024 Internal Audit plan was approved by the Committee and
is linked to the current risk profile of the organisation.
The Committee reviewed and approved the Internal Audit Charter, which remained unchanged from the
previous year.
The Committee assessed the effectiveness of Group Internal Audit during the year by means of a survey. The
responses to the survey questionnaire informed the Committee’s assessment. The Committee found Group
Internal Audit to be effective and concluded that the current Internal Audit structure was appropriate for the
size and requirements of the Group.
Risk management and internal controls
Although the Committee maintained its oversight of the principal and emerging risks during the year,
separate quarterly Risk Meetings were held as an extension of the main Board meeting, with all Board
members attending, in line with the Code’s requirements for all Board members to focus on risk
management.
The detailed principal and emerging risks are discussed further on pages 21 to 26.
The Committee was satisfied that the previously approved enterprise risk management framework remained
relevant and was being effectively adhered to.
The Committee considered the internal controls in place throughout the year to be effective.
Annual review
During the year the Committee updated its terms of reference to ensure these encompassed the updated
provisions of the Code. The Board evaluation undertaken included a review of the Audit Committee’s
performance within its remit.
Climate-related financial disclosures
The Audit Committee received reports on risk, strategy and governance processes related to climate change
and the associated financial disclosures up to the full adoption of the TCFD objectives, which was concluded
in June. The Audit Committee had oversight of climate-related risks and potential financial, strategy and
business planning impacts, through presentations to the Board during separate quarterly Risk Meetings.
During the year, the Audit Committee received feedback on:
• the adoption of the TCFD objectives;
• the Group's timeline and process leading up to the publishing of its 2030 decarbonisation strategy;
• the Group’s decarbonisation objectives;
• the timeline and process leading up to the adoption of the new global sustainability and climate disclosure
standards due to become effective from reporting periods commencing 1 January 2024, according to the
International Sustainability Standards Board (ISSB); and
• assurance, through the Sustainability Committee, on climate-related risk management effectiveness.

Financial disclosure
The Committee ensured that the Group’s Annual Report and Accounts 2023 and Half-Year Report 2023 were
fair, balanced and understandable by challenging and debating the judgements made by management and
ensuring that the information necessary for shareholders to assess the Group’s performance, business model
and strategy was provided. EY SA audited the Financial Statements included from pages 118 to 173 for the
year ended 31 December 2023 and issued an unmodified audit opinion in this regard.
The significant issues reviewed by the Committee relating to the 2023 results were:
• The assumptions in the Group’s financial forecasts incorporating the Group’s debt facilities and the status
of forecast future covenant compliance, mitigating actions available to the Group, and the appropriateness
of the going concern and viability assumptions and related disclosures. The Committee assessed the
disclosures in the Annual Report and Financial Statements in respect of going concern and covenant
compliance and concluded that they were appropriate. Refer to Note 1.2.2, Going concern on page 133 for
further details.
• The significant estimates and judgements applied in the valuation of the carrying value of mining assets,
intangible assets and impairment testing, considering the impact of the invasion of Ukraine and the conflict
in Gaza on inflation and costs, the availability of reliable power supply, production capabilities and
exchange rate fluctuations. The Committee critically reviewed the key assumptions and parameters
(diamond price forecasts and the discount rates applied in assessing the valuations) in the LoM plan for
Letšeng (currently an extended open pit plan including a new Satellite pipe Cut 6W cutback and steeper
slope angles in the Main pit) that supported the impairment tests performed by management, together
with the sensitivity analysis performed under various scenarios. The Committee noted the diamond price
recovery in the LoM plan given the depressed diamond market experienced in the year. The impact on the
LoM valuation caused by changes to the underlying operational plan, costs (including cost saving from
insourcing of the mining activities and further right-sizing at Letšeng) and capital expenditure assumptions
were noted. There was no impairment charge necessary and Letšeng’s carrying value remained above its
recoverable value, albeit at a lower headroom than the previous year. The Committee further reviewed the
relevant disclosure in the Financial Statements to ensure compliance with reporting standards.
• The judgements applied by management in the accounting recognition of the insourcing of the mining
activities as an asset acquisition and not a Business Combination in terms of IFRS 3. The Committee
assessed the judgement applied by management, and was satisfied that the concentration test, being that
the majority of the fleet purchased was concentrated into one class of asset with similar risks and inputs into
the mining activities, had been met. It was further satisfied that the consideration paid was the fair value of
the assets acquired and that the total purchase price was allocated to all the identifiable IAS 16 Property,
plant and equipment asset categories.
• The assumptions relating to the classification of tax uncertainties and the treatment and disclosure thereof.
Future focus areas
Specific focus areas for 2024 are to:
• continue to assess and monitor principal and emerging risks and their impact on the business;
• oversee the process of the change of auditor;
• assess the quality and effectiveness of the new auditor and the procedures and controls to ensure auditor
independence; and
• ensure adequate reporting against the Group’s decarbonisation strategy and set targets.

ANNUAL STATEMENT
Dear Shareholders
On behalf of the Board, I am pleased to present the Remuneration Committee’s Directors’ Remuneration Report for 2023. The report is
presented in three sections: this Annual Statement, the Directors’ Remuneration Policy (page 97) and the Annual Report on
Remuneration (page 103).
Linking Executive Directors’ remuneration with our purpose and strategy
Executive remuneration is focused on the underlying health and performance of the Group and considers key drivers, including relevant
ESG factors. Performance metrics consist of both financial and non-financial KPIs linked to our strategy, which in turn support the
Group’s purpose to produce the best diamonds, in the best way, leaving a lasting legacy. This purpose is relevant for our employees,
the communities in which we operate and shareholders alike. Each strategic pillar is linked to an element of remuneration as set out on
pages 97 to 102 of the Directors’ Remuneration Policy.
Remuneration decisions taken during 2023
Context
2023 has undeniably been a challenging period for the Group. The past year has presented a multitude of challenges, ranging from
global economic uncertainties to grid electricity supply disruptions at the Letšeng operation, all of which have significantly impacted the
ability to operate effectively.
In this challenging environment, characterised by persistent high inflation rates and escalating cost pressures, the task of ensuring fair
and competitive remuneration for executives has been particularly demanding. The Committee understands the importance of
attracting and retaining top talent, especially in times of uncertainty, and has endeavoured to strike a balance between offering
competitive compensation while safeguarding the long-term sustainability of the business.
The Group ended the year with a cash balance of US$16.5 million and drawn down facilities of US$37.8 million, resulting in a net debt
position of US$21.3 million. Underlying EBITDA decreased 65% to US$15.2 million from US$43.7 million in 2022, mainly driven by a
downturn in the market resulting in reduced revenue. The Board is not proposing a dividend based on the 2023 financial results due to
the volatility in the current economic outlook and the need to preserve the Group’s available cash resources.
At Letšeng, the successful conclusion of the right-sizing programme to align the workforce with operational requirements, as well as the
insourcing of the mining activities, provides a platform to increase operational efficiencies and realise cost savings from 2024 onwards.
Letšeng’s safety performance in 2023 was excellent, with its best all injury frequency rate on record. The Group’s carbon emission
reduction initiatives progressed well and it is on track to achieve its commitment to a 30% reduction in Scope 1 and 2 emissions by 2030,
as set out in the Climate Change report on page 59.
Through its remuneration strategies, the Group has remained steadfast in its commitment to fairness, transparency, and alignment with
organisational goals. Market trends have been closely monitored and remuneration benchmarked to ensure it remains competitive
within the industry, while also taking into account the unique challenges posed by the current environment.
In this context, the Committee’s key decisions during the year related to the following areas:
Governance
Gem Diamonds Limited Annual Report and Accounts 2023

Remuneration Policy Review
The current remuneration policy was adopted at the AGM in 2021 and June 2024 will mark the third anniversary of its adoption. The
Company will be submitting a proposed 2024 Remuneration Policy to shareholders at the 2024 AGM. The updated policy will become
effective from that date, if approved.
During 2023 and early 2024 the Committee reviewed the effectiveness of the current policy to ensure it remains appropriate for the
Company over the coming years. The Committee concluded that the current policy remains fit for purpose and proposed one change to
the malus and clawback provisions. These have been expanded to include provision for serious wrongdoing, serious reputational
damage and corporate failure.
Gem Diamonds Incentive Plan (GDIP)
The GDIP is based on a range of financial, operational and personal objectives that support the delivery of the Group’s key strategic
priorities, with 85% linked to business performance and 15% to personal performance.
In 2023 the CEO and CFO were awarded 363 544 and 250 863 nil-cost share options respectively under the deferred portion of the 2022
GDIP, as reflected on page 111.
The resulting formulaic GDIP outcome for the 2023 business scorecard was 35.5% of maximum (which accounted for 85% of the GDIP);
the personal performance outcomes (accounting for 15% of the GDIP) averaged 11% across the Executive Directors. The Committee
concluded that the 2023 GDIP outcome would be 45.5% for the CEO and 47.5% for the CFO. The Committee noted management’s
proposal to forego the cash element of the GDIP and to restrict the deferred shares element to more closely align with the shareholder
experience over 2023. The Committee agreed that only the deferred shares element would be awarded. The share price to be used to
determine the number of shares to be granted in 2024 under the deferred GDIP award will be 25 GB pence, rather than the prevailing
share price of c.10 GB pence at the time of the meeting. This will have the effect of reducing the number of shares to be granted in 2024
by c.59%, which also implies a lower aggregate bonus for the Executive Directors compared to 2022, as reflected in the single figure
emoluments table on page 108.
CEO Pay Ratio
We have not included a CEO pay ratio in this report, as the Company has no employees based in the UK, and any resulting ratios would
not be meaningful.
Implementation of the Remuneration Policy in 2024
The Executive Directors’ salaries were reviewed in February 2024, considering relevant benchmarks and in-country inflation. The review
was in line with the general practice of considering the wider employee group when applying inflation as a base for salary increases
across the Group. The Committee considered management’s recommendation that zero increases were to be awarded in light of the
current challenging environment the Group finds itself in. Based on all considerations, including current market conditions, the
Remuneration Committee determined that base salaries would not be increased in 2024. The wider workforce had been granted a 6.5%
salary increase, which took into account the year-on-year increase in inflation.
The Committee is also aware of the role it can play in supporting our employees in the current economic environment. It does this by
offering a range of benefits and programmes across the Group to support employees’ health, well-being and work-life balance.
For 2024, the GDIP will remain unchanged with a maximum annual award opportunity of 180% of salary. Group performance will
continue to be measured with reference to a business scorecard linked to the Group’s three strategic focus areas: Extracting Maximum
Value from Our Operations; Working Responsibly and Maintaining Our Social Licence; and Preparing for Our Future. Group
performance will be weighted 85% of maximum, with the remaining 15% linked to personal performance.
The Committee is mindful of the impact our operations have on the environment, and a Working Responsibly and Maintaining Our
Social Licence element has been included in the GDIP since it was first implemented in 2021. For 2024, this will include reducing our
environmental impact, diversity initiatives and various health and safety metrics. The Committee reviews the metrics on an annual basis
and will consider the options to include other ESG metrics, provided they align with our strategy at the time.
The incentive will be paid 55% in cash and 45% will be awarded through the issue of nil-cost options vesting in one-third annual tranches
after one, two and three years, subject to continued employment and good/bad leaver provisions over this period. Vested awards will
also be subject to a two-year post-vesting holding period, during which time Executive Directors may not sell shares except to cover
taxes associated with the exercising of share options. Malus and clawback provisions will apply during the performance period and for a
period of two years following payment.
Engagement
As we look towards the future, the Remuneration Committee remains dedicated to its responsibility of overseeing the fair and equitable
compensation of employees. We will continue to adapt our strategies in response to evolving market conditions, while remaining
vigilant in our efforts to balance the needs of our employees with the long-term interests of our shareholders.
I look forward to receiving your support at our 2024 AGM. The Board considers it important that shareholders have the opportunity to
raise questions with the Board. Shareholders are invited to send any questions they may have on this report or in relation to any of the
Committee’s activities. Please feel free to contact me through Minelle Zech, the Group Human Resources Executive, at

REMUNERATION POLICY
The proposed remuneration policy as set out in this section of the report will be put to a binding shareholder vote at the 2024 AGM
and, subject to shareholder approval, will become effective from the date of the 2024 AGM. The Committee considered the relevance
of the policy over the course of 2023 and at its February 2024 meeting and concluded that it remains fit for purpose. The Policy is as
disclosed in the 2022 Directors’ Remuneration Report save for some non-significant changes as follows:
• references to financial years have been updated where appropriate;
• references to performance measures have been updated for the latest business strategy, as appropriate;
• pay-for-performance charts have been updated to reflect 2024 salaries; and
• malus and clawback triggers have been expanded to include serious wrongdoing, serious reputational damage and corporate failure.
The Remuneration Policy is designed to provide a level of remuneration that attracts, retains and motivates executives of a suitably high
calibre to manage the business, implement the Group’s strategy and maximise long-term shareholder value. It is intended that, as far as
possible, remuneration policies and practices will conform to best practice in the markets in which the Group operates, will be aligned
with shareholder interests and will promote effective management of business risk.
The Committee’s policy is to provide base salaries and benefits that are fair and to weight remuneration towards variable pay. Variable
pay incentives are linked to the achievement of realistic performance targets relative to the Group’s strategy and corporate objectives.
The Committee is satisfied that the proposed policy is clear, simple, and appropriately aligned with the Group’s strategy, risk appetite
and culture, and that the incentives are appropriately capped.
How good governance informs policy design
The table below sets out the application of the Principles of the Code relating to the design of remuneration policies and practices:
Clarity
Targets for annual cash incentives and share awards are aligned to the Group’s strategic priorities.
This provides clarity to shareholders and other stakeholders on the relationship between the successful
delivery of the Group’s strategy and remuneration paid.
Simplicity
The Remuneration Policy is designed to be simple and clear while complying with all relevant regulatory
requirements and meeting shareholder expectations. It simplifies remuneration elements further by
combining the cash and deferred shares components into a single GDIP.
Risk
The Committee is aware of the risks that can result from excessive rewards and believes that the robust
target-setting and long history of applying discretion to formulaic outcomes reflects this. Malus and
clawback provisions in the Remuneration Policy further mitigate this risk.
Proportionality
The Committee’s overriding discretion ensures that remuneration outcomes are aligned with Group
performance.
Predictability
The GDIP ensures a simpler but more predictable range of performance outcomes that align with the
business model, ensuring predictable pay outcomes that do not reward poor performance.
Culture
As reflected in the Chairperson’s statement on page 11, the Committee considers overall pay and
conditions for employees across the Group when determining Executive Director outcomes.
Personal and Group performance measures include non-financial metrics linked to the Group’s purpose
and culture.
Policy table for Executive Directors
Salary
Purpose and link to
strategy
To offer a market-competitive base salary to recruit and retain individuals of the high calibre necessary
to execute the Group’s business strategy.
Operation
Base salaries are reviewed annually with changes effective from 1 April.
Salaries are typically set after considering the salary levels in companies of a similar size, complexity and
risk profile, the responsibilities of each individual role, progression within the role, and individual
performance.
In setting salaries for Executive Directors, the Committee takes note of the overall approach to salary
reviews for the wider employee group.
Opportunity
There is no prescribed minimum or maximum annual increase.
It is expected that salary increases for Executive Directors will ordinarily be (in percentage of salary
terms) in line with those of the wider employee group in countries of a similar inflationary environment.
In certain circumstances (for example, where there is a change in responsibility, role size or complexity,
or progression in the role), the Committee has discretion to award higher increases to ensure salary
levels remain competitive.

Benefits
Purpose and link to
strategy
To provide competitive benefits considering the market value of the role and benefits offered to the
wider UK management population, in line with the Group’s strategy to keep remuneration simple and
consistent.
Operation
Executive Directors receive a cash allowance in lieu of non-cash benefits.
Opportunity
The benefit value may vary by role to reflect market practice. It is not anticipated that the current cost of
benefits (as set out in the Annual Report on Remuneration) will increase materially over the term of this
policy, though the Committee retains discretion to approve a higher cost in exceptional circumstances.
Performance measures
N/A
Pension
Purpose and link to
strategy
To provide retirement benefits that are appropriately competitive.
Operation
Executive Directors receive a cash allowance in lieu of pension.
Opportunity
Any current and/or new Executive Director will receive pension benefits aligned to that of the wider
employee group (currently 7.5% of salary).
Performance measures
N/A
GDIP
Purpose and link to
strategy
To drive and reward performance against financial and non-financial KPIs, as well as personal
objectives, all of which are directly linked to business strategy.
Operation
The GDIP is reviewed annually by the Committee at the start of the year to ensure the opportunity and
performance measures are appropriate and continue to support business strategy.
The Committee has discretion to adjust the formulaic outcome of the bonus to more accurately reflect
the underlying business and personal performance during the year.
Performance is measured over one year, and earned awards are delivered 55% in cash and 45% in nil-
cost share options vesting in one-third annual tranches after one, two and three years, subject to
continued employment and good/bad leaver provisions over this period. Vested awards are also
subject to a two-year post-vesting holding period.
Malus and clawback provisions may be applied for a period of two years following payment in
exceptional circumstances, including, but not limited to, misstatement, misconduct, error, serious
wrongdoing, serious reputational damage and corporate failure.
Opportunity
Participants can receive a maximum of up to 180% of their base salary.
For threshold-level and target-level performance, the award earned is up to 20% and 50% of maximum
opportunity, respectively.
Performance measures
Performance is determined by the Committee annually by reference to a scorecard of Group targets as
detailed in the Group’s business plan and encapsulated in specific KPIs, as well as a discretionary
assessment of personal performance.
Group scorecard targets may include one or more of the three key strategic priority areas of Extracting
Maximum Value from Our Operations, Working Responsibly and Maintaining Our Social Licence, and
Preparing for Our Future. The Group scorecard will typically account for 85% of performance bonus in
any one year.
Details of the measures and weightings for the current year are provided in the Annual Report on
Remuneration.
Notes to policy table
Legacy arrangements
In approving this Policy, authority is given to honour any previous commitments or arrangements entered into with current or former
Directors (such as the unwinding of legacy share schemes) at a time when a previous remuneration policy was in force. Authority is also
given to honour arrangements agreed with an employee prior to the individual becoming a Director, if in the opinion of the Committee
the payment was not in consideration for the individual becoming a Director. Details of any such awards or payments are disclosed in
the Annual Report on Remuneration.
Selection of performance measures (GDIP)
Performance measures used in the Group’s executive incentive scheme – the GDIP – are selected to ensure incentives reinforce the
Group strategy and align executive interests closely with those of shareholders. It is the Committee’s opinion that the financial and non-
financial measures used in the GDIP support the strategic priorities of Extracting Maximum Value from Our Operations, Working
Responsibly and Maintaining Our Social Licence, and Preparing for Our Future, and are well accepted measures for the mining sector.
Governance
Gem Diamonds Limited Annual Report and Accounts 2023
98
Performance targets are set to be stretched but achievable, considering a range of reference points including the Group’s business
plan, its strategic priorities and the economic environment in which the Group operates. The Committee believes it has a robust
approach to target setting and the maximum outcomes are achievable only for exceptional performance.
Remuneration policy for other employees
Salary reviews are implemented with a consistent approach across the Group and consider the level of responsibility, experience,
individual performance, market levels and the Group’s ability to pay.
Senior management (below Board level) remuneration is reviewed by the Remuneration Committee. Senior management and
management level employees participate in an annual bonus scheme on a similar basis as the Executive Directors, although the
weighting on Group performance measures increases with seniority and share awards vary appropriately according to organisational
level.
Other employees participate in an annual bonus linked to operational metrics.
Shareholding guidelines
The in-post guideline requires Executive Directors to hold 200% of their salary in beneficially owned shares. Until the guideline has been
met, Executive Directors will be required to retain 50% of vested awards under the GDIP or any other share-based incentive.
The post-termination shareholding for Executive Directors requires that the in-post shareholding requirement is maintained for a period
of a year following cessation of employment, to be achieved through the continued holding of vested share awards granted after the
introduction of the 2021 Remuneration Policy.
A formal policy has been implemented to ensure in- and post-termination shareholding requirements are managed appropriately.
Pay for performance: scenario analysis for 2024
The table and subsequent graph below illustrate an estimate of the potential future remuneration for the Executive Directors and the
potential split between the different elements of pay under four performance scenarios: fixed, at target, maximum, and maximum +50%
share price appreciation. Potential remuneration is calculated on the incentive opportunities set out in the 2024 Remuneration Policy
applied to the salaries effective 1 April 2024.
The maximum GDIP is 180% of the salary.
The fixed scenario includes base salary, pension and benefits only.
The at-target scenario includes fixed remuneration as above, plus target pay-out of the GDIP.
The maximum scenario includes fixed remuneration, plus full pay-out and vesting of all incentives.
The maximum +50% scenario is the same as the maximum scenario, as the deferred share element of the GDIP is not subject to
performance conditions over the deferral period.
The assumptions are summarised in the table below:

Approach to remuneration on executive recruitment
The Committee will follow the Remuneration Policy as set out in the policy table when recruiting new Executive Directors. Any
arrangement specifically established to recruit an external Executive Director will be capped at the limits described in the policy table
on appointment. Where an individual forfeits outstanding incentive payments and/or contractual rights at a previous employer because
of their appointment, the Committee may offer additional compensatory payments or awards (buy-out) in such form as it considers
appropriate. Any such buy-out compensation would be on a comparable basis to the forfeited benefit, considering factors including the
performance conditions attached to these awards, the likelihood of conditions being met, and the remaining vesting period of these
awards. The Committee would normally use the remuneration components under the regular policy to make such buy-out awards, but
may also exercise its discretion under Listings Rule 9.4.2 if an alternative incentive structure were required. Where an Executive Director
is required to relocate from their home location to take up their role, the Committee may provide reasonable, time-limited assistance
with relocation in line with local market norms.
In the case of internal promotions, any commitments made prior to promotion and the approval of the Remuneration Policy (except for
pension entitlements) will be honoured. Where the new appointee has an initial salary set below market, any shortfall will be managed
with phased increases over a period of several years, subject to the individual’s performance and development in the role.
Service contracts
The Company’s policy is to limit termination payments to pre-established contractual arrangements. If the employment of an Executive
Director is terminated, any compensation payable will be determined in accordance with the terms of the service contract between the
Company and the employee, as well as the rules of any incentive plans. Details of the Executive Directors’ service contracts are
summarised in the table below.
Director Contract date Unexpired Notice period Contractual termination payment
CT Elphick 13 February 2007
Rolling contract 12 months
Pay basic salary on summary termination. Benefits
are payable only at the Committee’s discretion.
M Michael 22 April 2013
Payments for loss of office under all service contracts
On termination of an Executive Director’s contract, payments equal to salary in lieu of notice may be made monthly during the notice
period. Benefits are payable only at the Committee’s discretion. Payment in lieu of unused annual leave entitlement can be made at the
effective salary rate at the point of termination.
Where employment is terminated by the Company and the departing Executive Director has a legal entitlement (under statute or
otherwise) to additional amounts, these would need to be met. Should the Company wish to enter into a settlement agreement and the
individual seeks independent legal advice, the Committee retains discretion to settle any claims by or on behalf of the Executive
Director in return for making an appropriate payment and contributing to the legal fees incurred by the Executive Director in connection
with the termination of employment.
In exceptional circumstances, the Committee may approve new contractual arrangements with departing Executive Directors including
(but not limited to) settlement, confidentiality, outplacement services, restrictive covenants and/or consultancy arrangements. These will
be used only in circumstances where the Committee believes it is in the best interests of the Company and its shareholders to do so.

other benefits or remuneration are provided to non-Executive Directors.
Opportunity
There is no prescribed maximum annual increase.
It is expected that fee increases will typically be in line with market levels of fee inflation.
In certain circumstances (for example, where there is a change in time commitment required
or a material misalignment with market), the Committee has the discretion to adjust fee
levels to ensure they remain competitive.
The maximum aggregate annual fee for all non-Executive Directors, including the
Chairperson, allowed by the Company’s Articles of Association, is £750 000.

Considerations of shareholder views
The Committee considers shareholder views and the guidelines of investor bodies when determining remuneration. The Committee
values feedback from shareholders on the Company’s Remuneration Policy and commits to consulting shareholders in advance of any
significant changes to the policy. Details on the votes received on the 2022 Annual Report on Remuneration (at the 2023 AGM) and the
2021 Remuneration Policy (at the 2021 AGM) are provided in the Annual Report on Remuneration.
External directorships
Executive Directors are permitted to accept external directorships with prior approval of the Chairperson. Approval will only be given
where the appointment does not present a conflict of interest with the Group’s activities and the experience gained will be beneficial to
the development of the individual. Where fees are payable in respect of such appointments, these would be retained by the Executive
Director. Refer to page 107 for further details.

Consideration of independence
Ellason LLP was appointed by the Committee in January 2021 to provide independent remuneration advice to the Committee and attend
Committee meetings. Ellason LLP provides remuneration advice to a large portfolio of clients, including many in the FTSE 350 and FTSE
Small Cap, reassuring the Committee that the advice provided is appropriate and relevant. Ellason LLP is a signatory to, and abides by, the
Remuneration Consultants Group Code of Conduct. Further details can be found at www.remunerationconsultantsgroup.com.
Ellason LLP does not provide non-remuneration services to the Group and is in no other way connected to the Group, and is therefore
considered to be independent. The fees payable to them in relation to work for the Committee in 2023 were US$46 500, excluding VAT.
Summary of shareholder voting
The table below shows the results of the advisory vote on the 2022 Annual Report on Remuneration at the 2023 AGM and the binding

The 2022 Directors' Remuneration Report described the implementation of the Remuneration Policy approved at the 2021 AGM. Prior to
finalising the 2021 Remuneration Policy, the Board consulted its largest shareholders, and adapted the Remuneration Policy to align with
shareholder feedback. One significant shareholder has a materially different view on how the Remuneration Policy should be implemented,
and this impacted the vote on the 2022 Directors' Remuneration Report at the 2023 AGM. The Board has engaged with this shareholder since
the 2023 AGM to help ensure any continuing concerns are understood. The Committee further consulted shareholders on the proposed 2024
Remuneration Policy which will be submitted for a vote at the 2024 AGM. Feedback from all shareholders was considered during the
Committee’s deliberations over the 2024 Remuneration Policy which will be presented to shareholders for approval at the 2024 AGM.
Wider employee considerations
The Committee considers Executive Director remuneration in the context of pay policies and practices across the wider employee group.
We value and appreciate the contribution made by our employees and aim to provide them with market-competitive remuneration and
benefit packages. Our approach to remuneration for our wider employee group is similar to that of Executive Directors and includes both
fixed and performance-based components.
Base salaries are reviewed annually, and any increases become effective from either 1 January or 1 March, dependent on operation-specific
remuneration policies. The Committee reviews salary increases for the wider employee group and significant changes in practice or policy.
The average salary increase awarded to the wider workforce was 7.8% for 2023, which took into account the year-on-year increase in
inflation. All employees participate in an annual discretionary bonus scheme that rewards both an employee’s contribution to the
performance of the Group and their individual performance.
The majority of our employees receive an employer pension contribution equal to 7.5% of salary per annum and may opt to join a medical
aid scheme to which the Company contributes 50% up to a capped amount. We also offer a wide range of benefits and programmes
throughout the Group to support employees’ health, well-being and work-life balance. Benefits and programmes vary from site to site, and
include employee wellness and/or access to a counsellor, an employee communications app, on-site gym and/or recreation centres, travel
subsidies, a flexible working environment and paying for professional subscriptions.
We have an open, collaborative and inclusive management structure and engage regularly with our employees on a range of issues. The
designated non-Executive Director, Mazvi Maharasoa, conducts formal engagement sessions with workforce committees across the Group.
During 2023 the Remuneration Committee Chairperson attended one engagement session per operational site. This afforded the
opportunity for engagement with the workforce as to how executive remuneration supports strategy and aligns with that of the employees.
Company culture is monitored and assessed by the Board on a quarterly basis against pre-determined metrics.
Gender pay considerations
We have not included a UK gender pay gap report, as the Company has no employees based in the UK, and any resulting ratios would
not be meaningful. The Committee reviewed gender pay across the various employee levels in the Group and is satisfied that no
material differences exist between genders.
Relative importance of spend on pay

buybacks and return of capital) from the financial year ended 31 December 2022 to the financial year ended 31 December 2023.

Share options under the deferred portion of the 2023 GDIP will be awarded in 2024 following the release of the 2023 annual results. The Committee applied its discretion in awarding
deferred share options at a price of 25 GB pence rather than the prevailing share price of c.10 GB pence. This will have the effect of reducing the number of shares granted by c.59%,
which also implies a lower aggregate bonus for the Executive Directors compared to 2022.
2
The waiver of the cash element of the annual bonus, together with the lower deferred shares as set out in the above note, results in an effective 9% annual bonus outcome against
the maximum achievement.

Following the implementation of the GDIP in 2021, no share options have been awarded subject to performance conditions and no vesting of awards were subject to 2023
performance conditions.

The percentage change in Director remuneration compared to other employee
pay
The table below shows a comparison of the annual change of each individual Director’s pay to the annual change in average employee
pay for the year ended 31 December 2023. Average employee pay is calculated using the approved basic salary increase for 2023. The
parent company consists of only Directors, and the Company therefore chose to voluntarily disclose the change in Directors’
remuneration compared to a wider employee comparator group, as this will provide a more representative comparison.

The comparator group is made up of Letšeng Diamond employees which in turn make up 87% of the Group’s employees.
Executive Directors’ external appointments
Apart from interests in private entities, only Clifford Elphick holds any significant executive directorship or appointments outside the
Group. He is appointed as the non-Executive Chairperson of Zanaga Iron Ore Co Limited, which listed on the AIM Market of the London
Stock Exchange in November 2010. Total fees paid to Clifford Elphick by Zanaga are £83 000. Any fees paid to Clifford Elphick in
fulfilling these external roles are retained by him.
Salary increases
The Committee approved a 4% salary increase for the Executive Directors in 2023, effective 1 April 2023:

Pension and other benefits
No formal pension provision is made by the Company, but Executive Directors receive a cash allowance in lieu of pension. On 1 January
2023 the pension allowance for both the CEO and CFO was reduced to 7.5% of salary to be fully aligned with pension contributions to
the wider employee group. Executive Directors received a cash allowance in lieu of other non-cash benefits, the values of which were
6.0% of salary respectively for the CEO and the CFO.

prevailing share price of c.10 GB pence. This will have the effect of reducing the number of shares granted by c.59%, and also implies a lower aggregate bonus for the Executive Directors than that paid in 2022.

GDIP in respect of 2023 performance
Executive Directors participated in the GDIP in 2023, a discretionary incentive arrangement focused on the strategic areas of Extracting
Maximum Value from Our Operations, Working Responsibly and Maintaining Our Social Licence, and Preparing for Our Future, all of
which are underpinned by specific KPIs and included in the business plan approved by the Board.
In 2023, the maximum award opportunity for the Executive Directors was 180% of base salary. The earned incentive is paid in cash (55%)
and a nil-cost share award (45%), with vesting subject to continued employment over three years. Pay-out is based 85% on a business
scorecard and 15% on personal objectives assessed on a discretionary basis by the Remuneration Committee. The business scorecard
performance measures, targets and actual results for 2023 are disclosed in full in the table below.

The Committee reviewed progress against the strategic focus elements of Long-term mine planning and optimisation, the ‘Assessment of external growth opportunities’ and the
‘Advancement of innovative technologies’. It was determined that a score of 7.7 out 10 is appropriate.
In assessing the discretionary element of Preparing for Our Future, the Committee considered the following three areas set out as the
strategic focus for the year:
Long-term mine planning and optimisation
• The successful insourcing of the mining activities has provided the platform to enhance operational efficiencies and decrease
operating costs in future.
• The right-sizing programme at Letšeng effectively aligned the workforce to future operational requirements.
• A study to introduce a steeper conventional concept in the basalt of SC6W has been commissioned; the initial slope design has been
approved and the requisite support design and costs are being analysed.
Assessment of external growth opportunities
During the year, numerous assets and projects were reviewed and a number of parties were engaged as part of the strategic focus on
growth and expansion.
Advancement of innovative technologies
Various new technologies were tested for their ability to reduce diamond breakage and detect diamonds in kimberlite.

Personal performance
15% of the GDIP is linked to personal performance, with objectives linked to each Executive Director’s individual areas of responsibility
and designed to collectively support the achievement of the Group’s strategic targets for the year. Individual targets comprise
contributions to the Group’s overall performance and the delivery of strategic projects and initiatives as set out by the Board, including
operational performance, strengthening of key stakeholder relationships, bank financing, treasury management, ESG objectives and
strategy development and implementation. Following the Committee's consideration of the Executive Directors' personal performance
as set out in the tables below, the Committee awarded scores of 10.0% and 12.0% (out of 15%) respectively for the CEO and CFO.

Preparing for Our Future
• During the year, numerous assets and projects were reviewed and a number of parties were engaged as
part of the strategic focus on growth and expansion.
Extracting Maximum
Value from Our
Operations
• In 2022, an agreement was entered into with two important diamond manufacturing customers who will
supply polished diamonds to some of the world’s most premium luxury jewellery brands. These diamonds
are polished to the clients’ specifications and additional value is realised for the Group as it shares in a
percentage of the polished sales price of these diamonds. Additional revenue earned from the sale of
these diamonds amounted to US$0.9 million in 2023.
Working Responsibly
and Maintaining Our
Social Licence
• Succession planning across the Group was progressed with an increased focus on diversity and inclusion.
Senior management diversity increased, although the rationalisation process at Letšeng impacted the
ability to increase the overall diversity of the Group.
• Decarbonisation initiatives progressed well during the year, keeping the Group on track to realise its
decarbonisation target of a 30% reduction in Scope 1 and 2 emissions by 2030 against a 2021 baseline. In
2023, a 26% reduction against this baseline was achieved.
• Excellent safety performance with the best all injury frequency rate on record.

Strategic focus area Performance
Preparing for Our Future
• The underground study was completed at a pre-feasibility level. Based on the current economic
environment and input, the underground mining project in the Satellite pit was found to be not
economically viable but will be reconsidered in case of a change in macro-economic conditions that has a
positive impact on the diamond market and prices.
• Successful conclusion of the mining activities insourcing has led to enhanced operational efficiencies and
cost reductions going forward. The transition to owner mining also provides a platform for further
enhancing operational efficiencies and reducing costs.
• A study to introduce a steeper conventional concept in the basalt of SC6W has been commissioned; the
initial slope design has been approved and the requisite support design and costs are being analysed.
Extracting Maximum
Value from Our
Operations
• Initiatives to reduce energy consumption include the replacement of existing lighting at Letšeng with
energy-efficient lighting and the implementation of a solar power solution at Ghaghoo to replace the
diesel-powered generator entirely.
• Initiatives to improve plant stability by decreasing the instantaneous feed rates to the treatment plants
resulted in an increase in overall plant utilisation, ore treated and grade recovered in H2 2023.
• The right-sizing programme at Letšeng effectively aligned the workforce to future operational
requirements.
Working Responsibly
and Maintaining Our
Social Licence
• The Group successfully completed the final phase of our three-year TCFD adoption journey. This
included the adoption of a decarbonisation target of 30% reduction in Scope 1 and 2 emissions by 2030
(against a 2021 baseline), and monitoring and measuring our progress against these targets.
• Extensive site clean-up and partial rehabilitation activities were performed at Ghaghoo for possible
closure or handover to government.
The formulaic outcome from the business scorecard for Group performance was 35.5% (out of the maximum 85%) which, combined with
the personal element, resulted in formulaic GDIP outcomes of 45.5% and 47.5% of maximum for the CEO and the CFO, respectively.
The Committee noted management’s proposal to forego the cash element of the GDIP and to restrict the deferred shares element to
align more closely with the shareholder experience over 2023. The Committee agreed that only the deferred shares element would be
awarded and that the share price to be used to determine the number of shares to be granted in 2024 under the deferred GDIP award
would be 25 GB pence, rather than the prevailing share price of c.10 GB pence at the meeting when the Committee reviewed the GDIP
outcome. This will have the effect of reducing the number of shares to be granted in 2024 by c.59%, which also implies a lower
aggregate bonus for the Executive Directors compared to 2022.

The Committee deemed it appropriate to calculate the total shareholding as a % of salary based on the share price at the time of issue/purchase. This differs from previous reporting
where the 3-month average to the end of the financial year was used in the calculation. In applying the 3-month average calculation, the shareholding would be 237% and 21%
respectively for the CEO and CFO.
2
C Elphick is interested in these ordinary shares by virtue of his interest as a potential beneficiary in a discretionary trust which has an indirect interest in those ordinary shares.

In terms of the shareholding guidelines, M Michael is required to retain at least 50% of his vested awards until the guideline of 200% of basic salary has been met.

Implementation of remuneration policy for 2024
The Committee considered management’s recommendation that zero increases were to be awarded in light of the current challenging
environment the Group finds itself in. Based on all considerations, including current market conditions, the Committee determined that
base salaries would not be increased in 2024. The wider workforce had been granted a 6.5% salary increase, which took into account the
year-on-year increase in inflation.

Pension and benefits
The Executive Directors will continue to receive cash supplements in lieu of pension and benefits in 2024. Pension benefits are fully
aligned with that of the wider employee group at 7.5% of base salary. Pension contributions to any new Executive Director
appointments will be capped at the prevailing wider employee group pension rate at the time.
The allowance in lieu of non-cash benefits will be 6% of salary for both the CEO and CFO.
Gem Diamonds Incentive Plan
The Executive Directors will participate in the GDIP in line with the remuneration policy, with a maximum award opportunity of 180% of
salary, and with pay-out based on a scorecard of financial, operational and personal objectives measured over the financial year.
The performance measures will continue to support the delivery of the Group’s key strategic priorities as set out on page 18 of this
Annual Report and Accounts 2023, with 85% linked to business performance and 15% to personal performance. For the business
performance element, performance may continue to be linked to the Group’s three key strategic priorities of Extracting Maximum Value
from Our Operations, Working Responsibly and Maintaining Our Social Licence, and Preparing for Our Future. The weightings that
apply to the elements of the scorecard for 2024 are summarised in the table below.

This element of the bonus captures several key metrics around the Group’s environmental, safety and social performance. Consistent with
the other measures for the GDIP scorecard, the exact measures and targets will be disclosed in full in the 2024 remuneration report.
Targets are considered sensitive and will be disclosed in full on a retrospective basis in next year’s report. In approving these targets,
the Committee considered a range of perspectives on performance outcomes, including internal and external reference points. More
detail is given on the selection of GDIP performance measures on page 98 of this report.
Dilution
Employee share awards may be satisfied with newly issued shares subject to
aggregate dilution limits. The issue of shares to satisfy awards under the Company’s
share schemes will not exceed 10% of the Company’s issued ordinary share capital in
any rolling 10-year period. As of 31 December 2023, a total of 14 121 018 shares (10%
of issued share capital) may be issued pursuant to all current awards outstanding over
the last 10 years.

DIRECTORS’ REPORT
The Directors are pleased to submit the financial statements of the Group for the year ended 31 December 2023.
As a British Virgin Islands-registered company, Gem Diamonds Limited (company registration number: 669758) is not required to
conform with the Companies Act, 2006. However, the Directors have elected to conform to the requirements of the Companies Act,
2006.
Accordingly, Directors must present a Strategic Report and a Directors’ Report to inform shareholders of the Group’s performance and
prospects and help them evaluate whether the Directors performed their fiduciary duty. The 2023 Annual Report and Accounts discloses
how the Directors have performed their duty to ensure the Group’s continued success and sustainability, in line with the Companies Act,
2006.
In line with Disclosure Guidance and Transparency Rules (DTR 4.1.5R(3) and DTR 4.1.8R), the required content of the Management
Report can be found in the Strategic Report, the Performance Review and the Directors’ Report, the Governance section and other
sections of the 2023 Annual Report and Accounts, indicated by a reference.
The Strategic Report can be found on pages 2 to 62. This will provide the shareholders with a balanced assessment of the Group’s
business including a description of its principal risks and uncertainties. It may not be relied upon by anyone, including the Company’s
shareholders, for any other purpose.
Forward-looking statements
The Strategic Report and other sections of this report contain forward-looking statements. Forward-looking statements, by their nature,
involve several risks, uncertainties and future assumptions because they relate to events and/or depend on circumstances that may or
may not occur in the future. The actual results and outcomes may differ materially from those expressed or implied by the forward-
looking statements. No assurance can be given that the forward-looking statements in the Strategic Report will be realised. Statements
about the Directors’ expectations, beliefs, hopes, plans, intentions and strategies are subject to change and are based on expectations
and assumptions about future events, circumstances and other factors which are, in many instances, outside the Company’s control.
The information in the Strategic Report was prepared based on the knowledge and information available to the Directors at the time of
its preparation. The Company is under no obligation to update or revise the Strategic Report during 2024. The expectations set out in
the forward-looking statements are reasonable but may be influenced by several variables which could cause actual results or trends to
differ materially. Forward-looking statements need to be read in context with actual historic information provided. The Company’s
shareholders are cautioned not to place undue reliance on the forward-looking statements. Shareholders should note that the Strategic
Report has not been audited.
CORPORATE GOVERNANCE
DTR 7.2 requires certain information to be included in a corporate governance statement set out in the Directors’ Report. The Group
has an existing practice of issuing a separate Corporate Governance Code Compliance Report as part of its Annual Report and
Accounts. The information required by the Disclosure Guidance and Transparency Rules and the UK Financial Conduct Authority’s
Listing Rules (LR 9.8.6) is located on pages 2 to 113.
DIRECTORS
The Directors, as at the date of this report, are listed on pages 179 to 181 together with their biographical details. Details of the
Directors’ interests in shares and share options of the Company can be found on page 111.

Appointment and re-election of Directors
The Board’s formal Selection and Appointment Policy ensures that the procedure for appointing new Directors is formal, rigorous and
transparent, and appointments are made on merit, against objective criteria. The Nominations Committee makes appointments based
on merit while considering diversity (of gender, social and ethnic background), cognitive and personal strengths and specialist skill sets.
The Articles of Association (82) provide that a third of Directors retire annually by rotation and, if eligible, offer themselves for re-
election. However, in accordance with the Code, all the Directors retire at the AGM and, subject to being eligible, offer themselves for
re-election.
Payments for loss of office due to change of control
The basis for payments for loss of office to Executive Directors due to a change in control can be found on page 100.
PROTECTION AVAILABLE TO DIRECTORS
By law, the Directors are ultimately responsible for most aspects of the Group’s business dealings. This means they face potentially
significant personal liability under criminal or civil law, or the UK Listing, Prospectus and Disclosure and Transparency Rules, and face a
range of penalties including private or public censure, fines and/or imprisonment. In line with normal market practice, the Group
understands that it is in its best interests to protect its Board members from the consequences of innocent error or omission. This allows
the Group to attract prudent individuals to act as Directors.
The Group maintains, at its expense, a Director and Officer’s liability insurance policy to provide indemnity, in certain circumstances, for
the benefit of Directors and other Group employees.
Refer to the Corporate Governance statement on page 72 for further details.
DIRECTORS’ INTERESTS
No Director had, at any time during the year, a material interest in any contract of significance in relation to the Company’s business.
The interests of Directors in the shares of the Company are included on page 111.
SUPPLIERS AND CUSTOMERS
We engage extensively with suppliers and contractors to ensure alignment, mutual understanding and the sustainability of all parties.
The early termination (by mutual agreement) of the mining services contract and subsequent insourcing thereof was concluded in
December 2023.
We have sound relationships with our customers. We interact with customers regularly in the normal course of business and at tenders.
We continued to hold regular diamond tender viewings in Antwerp during the year. We were able to rely on the loyal customer base for
support during the year while the diamond market was under significant pressure. The agreement entered in 2022 with two diamond
manufacturing customers to supply polished diamonds to some of the world’s most premium luxury brands remained in effect in 2023.
Refer to our stakeholder relationships section on pages 14 to 17 for more details on our engagement with suppliers, contractors and
customers.
RESULTS AND DIVIDENDS
The Group’s attributable loss after taxation amounted to US$2.1 million (2022: profit of US$10.2 million).
The Group’s detailed financial results are set out in the financial statements on pages 118 to 173.
The Board is not proposing a dividend based on the 2023 financial results due to the volatility in the current economic outlook, the
Group’s available cash resources and the current business outlook.
The Group’s dividend policy sets the appropriate dividend each year, and considers:
• The Group’s cash resources.
• The level of free cash flow and earnings generated during the year.
• Expected funding commitments for future capital projects.
The Board will consider special dividends in the event of significant diamond recoveries and will consider further share buyback
programmes if appropriate.
GOING CONCERN
The Group business activities, together with the factors likely to affect its future development, performance and position, are set out in
the Strategic Report on pages 2 to 62. The financial position of the Group, its cash flows and liquidity position are described in the
Strategic Report on pages 34 to 40. In addition, Note 1.2.2, Note 25 and Note 27 to the financial statements include the Group’s going
concern policy and its objectives, policies and processes for managing its capital; its financial risk management objectives; details of its
financial instruments; and its exposures to credit and liquidity risk.
The Directors have a reasonable expectation that the Group has adequate financial resources to continue operations for the
foreseeable future. This follows a review of forecasts, budgets, timing of cash flows, the likely successful renewal of its debt facilities,
various cost-reduction initiatives, sensitivity analyses and the uncertainties disclosed in this report. For this reason, the Directors
continue to adopt the going concern basis in preparing the Annual Report and Accounts of the Group.

VIABILITY STATEMENT
In accordance with provision 30 of the 2018 UK Corporate Governance Code, the Directors have assessed the prospects of the Group
over a period longer than the 12 months required by the “going concern” provision. The viability statement, aligned with Provision 31 of
the UK Corporate Governance Code 2018, is included in the Strategic Report on page 27.
SUBSEQUENT EVENTS
Refer to Note 29 of the financial statements for details of events subsequent to the reporting date.
SHARE CAPITAL AND VOTING RIGHTS
Details of the authorised and issued share capital of the Company, including the rights pertaining to each share class, are set out in
Note 15 to the financial statements.
As at 13 March 2024, there were 139.7 million fully paid ordinary shares of US$0.01 each in issue and listed on the official list maintained
by the Financial Conduct Authority in its capacity as the UK Listing Authority. In addition, the Company holds 1.5 million shares as
treasury shares acquired during the share buyback programme that was launched in 2022. These treasury shares are not entitled to
dividends and have no voting rights.
The Company has one class of ordinary shares. Shareholders have the right to receive notice of and attend, speak and vote at any
general meeting of the Company. Shareholders may be present in person (or, being a corporation, by representative) or by proxy at a
general meeting. Every shareholder present in person (or, being a corporation, by representative) or by proxy will have one vote in
respect of every ordinary share they hold. The appointment of a proxy to vote at a general meeting must be received no less than 48
hours before the meeting’s appointed time.
Shareholders have the right to participate in dividends and other distributions according to their respective rights and interests in the
profit of the Company.
No shareholders have any special rights with regard to the control of the Company. The Company is not aware of any agreements
between shareholders which may result in restrictions on transfers or voting rights, save as mentioned below.
There are no restrictions on the transfer of ordinary shares other than:
• As set out in the Company’s Articles of Association.
• Certain restrictions may from time to time be imposed by laws and regulations.
• Pursuant to the Company’s share dealing code whereby the Directors and employees of the Company require approval to deal in the
Company’s ordinary shares.
At the AGM held in June 2023, the Board noted the proportion of the votes cast against the resolution referring to the authority of
Directors to allot shares (Resolution 12 passed with 69.5% of participating shareholders voting in favour). The CEO met the significant
shareholder who voted against Resolution 12 to discuss their voting policy, and although the shareholder has a standing position on
these resolutions, the Board will regularly consider its approach to this matter. The resolution reflected UK-listed company market
practice, and the Board considers the flexibility afforded by the authority to allot shares to be in the best interest of the Company.
At the same AGM, shareholders authorised the Company to make on-market purchases of up to 14 121 018 of its ordinary shares,
representing approximately 10% of the Company's issued share capital at that time. In 2022, the Company purchased 1 520 170 of its
ordinary shares, which are being held as treasury shares and may be used to settle ESOP and GDIP awards.
At the 2024 AGM, shareholders will be requested to renew this authority. The Directors continue to consider various options and keep
the authorisation under regular review. The 2024 Notice of AGM will set out the details regarding exercising voting rights and proxy
appointments.
MAJOR INTERESTS IN SHARES
Details of the major interests (at or above 3%) in the issued ordinary shares of the Company are set out in the Strategic Report on page
15.
ARTICLES OF ASSOCIATION
Any proposed amendments to the Articles of Association of the Company need to be approved by shareholders by special resolution.

RESPONSIBILITY STATEMENT OF THE
DIRECTORS IN RESPECT OF THE ANNUAL
REPORT AND FINANCIAL STATEMENTS
The Directors are responsible for preparing the Annual Report and the Group financial statements in accordance with International
Financial Reporting Standards (IFRS). Having taken advice from the Audit Committee, the Board considers that this report and financial
statements taken as a whole, are fair, balanced and understandable and that they provide the information necessary for shareholders to
assess the Group’s performance, business model and strategy.
The Strategic Report and Directors’ Report include a fair review of the development and performance of the business and the position
of the Group and the undertakings included in the consolidation taken as a whole, together with a description of the principal risks and
uncertainties that the Group faces.
PREPARATION OF THE FINANCIAL STATEMENTS
In preparing the Group financial statements, the Directors are required to:
• select suitable accounting policies and then apply them consistently;
• make judgements and estimates that are reasonable and prudent;
• state whether they have been prepared in accordance with IFRS;
• state whether applicable IFRS have been followed, subject to any material departures disclosed and explained in the Group financial
statements; and
• prepare the financial statements on the going concern basis unless it is inappropriate to presume that the Group will continue in
business.
The Directors are responsible for keeping adequate accounting records that are sufficient to show and explain the Group’s transactions
and disclose, with reasonable accuracy at any time, the financial performance, the financial position and cash flow of the Group. They
are also responsible for safeguarding the assets of the Group and hence for taking reasonable steps for the prevention and detection of
fraud and other irregularities.
The Directors confirm that the financial statements, prepared in accordance with IFRS, give a true and fair view of the assets, liabilities,
financial position at year end and profit or loss for the year then ended of the Group and the undertakings included in the consolidation
taken as a whole. In addition, suitable accounting policies have been selected and applied consistently.
Information, including accounting policies, has been presented in a manner that provides relevant, reliable, comparable and
understandable information, and additional disclosures have been provided when compliance with the specific requirements in IFRS
have been insufficient to enable users to understand the financial impact of particular transactions, other events and conditions on the
Group’s financial position, cash flow and financial performance. Where necessary, the Directors have made judgements and estimates
that are considered reasonable and prudent.
The Directors of the Company have elected to comply with the Companies Act, 2006, in particular the requirements of Schedule 8 to
The Large and Medium-sized Companies and Groups (Accounts and Reports) Regulations 2013 of the United Kingdom pertaining to
Directors’ remuneration which would otherwise only apply to companies incorporated in the UK.

INDEPENDENT AUDITOR’S REPORT
To the Shareholders of Gem Diamonds Limited
REPORT ON THE AUDIT OF THE CONSOLIDATED FINANCIAL
STATEMENTS
Opinion
We have audited the consolidated financial statements of Gem Diamonds Limited and its subsidiaries (‘the Group’) set out on pages
123 to 173, which comprise the consolidated statement of financial position as at 31 December 2023, and the consolidated statement of
profit or loss, the consolidated statement of comprehensive income, the consolidated statement of changes in equity and the
consolidated statement of cash flows for the year then ended, and notes to the consolidated financial statements, including material
accounting policy information.
In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the
Group as at 31 December 2023, and its consolidated financial performance and consolidated cash flows for the year then ended in
accordance with International Financial Reporting Standards (“IFRS”).
Basis for Opinion
We conducted our audit in accordance with International Standards on Auditing (“ISAs”). Our responsibilities under those standards are
further described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are
independent of the Group in accordance with the Independent Regulatory Board for Auditors’ Code of Professional Conduct for
Registered Auditors (“IRBA Code”) and other independence requirements applicable to performing audits of financial statements of
the Group and in South Africa. We have fulfilled our other ethical responsibilities in accordance with the IRBA Code and in accordance
with other ethical requirements applicable to performing audits of the Group and in South Africa. The IRBA Code is consistent with the
corresponding sections of the International Ethics Standards Board for Accountants’ International Code of Ethics for Professional
Accountants (including International Independence Standards). We believe that the audit evidence we have obtained is sufficient and
appropriate to provide a basis for our opinion.
Key Audit Matters
Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the consolidated
financial statements of the current period. These matters were addressed in the context of our audit of the consolidated financial
statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. For each
matter below, our description of how our audit addressed the matter is provided in that context.
We have fulfilled the responsibilities described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements
section of our report, including in relation to this matter. Accordingly, our audit included the performance of procedures designed to
respond to our assessment of the risks of material misstatement of the financial statements. The results of our audit procedures,
including the procedures performed to address the matter below, provide the basis for our audit opinion on the accompanying
consolidated financial statements.

Key Audit Matter How the matter was addressed in the audit
GOODWILL IMPAIRMENT
Management performs an annual impairment test on goodwill as
required by IAS 36 Impairment of Assets using discounted future
cash flows to determine the recoverable amount. Goodwill relates
to the Group’s investment in the Letšeng Diamond mine. The
carrying value of goodwill amounts to US$10.4 million (2022:US$11.2
million).
There is an inherent uncertainty in forecasting and discounting
future cash flows, which forms the basis of the Group’s recoverable
amount calculations. This was amplified by uncertainties in various
world economies which impacted the depressed diamond prices,
operating costs, exchange rates and discount rates resulting in
additional audit work in assessing the Group’s impairment model.
As disclosed in Note 11 Impairment testing and Note 1.2.26 Critical
accounting estimates and judgements, the Group uses discounted
cash flows to determine the recoverable amount for each cash
generating unit, based on the following key assumptions:
• Rough diamond prices;
• Inflation rates;
• Production costs and volumes; and
• Discount rates
The current year impairment model further includes certain
assumptions that materially impact the recoverable amount – this
include the re-optimisation of the pits which resulted in lower
reserves and ultimately reducing the life of mine from 2040 to 2038 -
this further impacted waste and ore volumes.
Given the above factors, the goodwill impairment, required
significant audit effort including the use of our valuation experts in
the audit of the recoverable amount.
Our audit procedures included amongst others the following:
• We involved our internal valuation specialists as part of our team
to assist in evaluating management’s impairment methodology
and key assumptions used in the impairment calculations;
• Our valuation specialists evaluated the valuation methodology
against acceptable industry methods and accounting standards;
• Our valuation specialists calculated two independent weighted
average cost of capital (WACC) rates (Revenue and costs) to
compare to management’s WACC’s. Our independent WACC
recalculations were based on publicly available market data for
comparable companies for the Letšeng Cash Generating Unit
(CGU);
• Our valuation specialists calculated an independent net present
value (NPV) to compare to management’s NPV;
• Our valuation specialists assessed the reasonability of the
significant inputs and assumptions used in the impairment
models, such as diamond prices and growth, by comparing them
to independent sources. Assumptions such as production costs
and volumes were considered for reasonability with reference to
history, the mine plan and reserves;
• We have performed sensitivity analyses around the key
assumptions used in the impairment model. We did this by
increasing and decreasing the following assumptions in the
model to determine the impact on the headroom (difference
between the carrying value of the CGU and the recoverable
amount). These included:
▪ WACC;
▪ Processing costs; and
▪ Diamond prices
• Our valuation specialists considered the re-optimisation and the
impact on the life of mine in the context of the reserves.
• We assessed the adequacy of the Group’s disclosures in terms of
IAS 36, in the notes to the consolidated financial statements.
Other Information
Management is responsible for the other information. The other information comprises the information included in the 183-page
document titled “Gem Diamonds Annual Report and Accounts 2023”. The other information does not include the consolidated financial
statements and our auditor’s reports thereon.
Our opinion on the consolidated financial statements does not cover the other information and we do not express an audit opinion or
any form of assurance conclusion thereon.
In connection with our audit of the consolidated financial statements, our responsibility is to read the other information and, in doing so,
consider whether the other information is materially inconsistent with the consolidated financial statements, or our knowledge obtained
in the audit, or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a
material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.
Responsibilities of Management for the Consolidated Financial Statements
Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with IFRS,
and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements
that are free from material misstatement, whether due to fraud or error.
In preparing the consolidated financial statements, management is responsible for assessing the Group’s ability to continue as a going
concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless
management either intends to liquidate the Group or to cease operations, or has no realistic alternative but to do so.

Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements
Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from
material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is
a high level of assurance but is not a guarantee that an audit conducted in accordance with ISAs will always detect a material
misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate,
they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial
statements.
As part of an audit in accordance with ISAs, we exercise professional judgement and maintain professional scepticism throughout the
audit. We also:
• Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design
and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a
basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error,
as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group’s internal control.
• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures
made by management.
• Conclude on the appropriateness of management’s use of the going concern basis of accounting and based on the audit evidence
obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group’s ability
to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s
report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion.
Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or
conditions may cause the Group to cease to continue as a going concern.
• Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and
whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair
presentation.
• Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the group
to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision, and performance of
the Group audit. We remain solely responsible for our audit opinion.
We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and
significant audit findings, including any significant deficiencies in internal control that we identify during our audit.
We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding
independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our
independence, and where applicable, actions taken to eliminate threats or safeguards applied.
From the matters communicated with those charged with governance, we determine those matters that were of most significance in the
audit of the consolidated financial statements of the current period and are therefore the key audit matters. We describe these matters
in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances,
we determine that a matter should not be communicated in our report because the adverse consequences of doing so would
reasonably be expected to outweigh the public interest benefits of such communication.

1. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)
1.1 Corporate information (continued)
1.1.3 Segment information
For management purposes, the Group is organised into geographical units as its risks and required rates of return are affected
predominantly by differences in the geographical regions of the mines and areas in which the Group operates or areas in which
operations are managed. The below measures of profit or loss, assets and liabilities are reviewed by the Chief Operating Decision-
Maker, ie Board of Directors. The main geographical regions and the type of products and services from which each reporting segment
derives its revenue from are:
• Lesotho (diamond mining activities);
• Belgium (sales, marketing and manufacturing of diamonds);
• BVI, RSA, UK and Cyprus (technical and administrative services); and
• Botswana (diamond mining activities, currently on care and maintenance)
Management monitors the operating results of the geographical units separately for the purpose of making decisions about resource
allocation and performance assessment.
Segment performance is evaluated based on operating profit or loss. Intersegment transactions are entered into under normal arm’s
length terms in a manner similar to transactions with third parties. Segment revenue, segment expenses and segment results include
transactions between segments. Those transactions are eliminated on consolidation.
Segment revenue is derived from mining activities, polished manufacturing margins, and diamond analysis and manufacturing services.
The following tables presents revenue from contracts with customers, profit/(loss) for the year, EBITDA and asset and liability
information from operations regarding the Group’s geographical segments:

1.2 Summary of material accounting policies
1.2.1 Basis of preparation
The financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (IFRS), as
issued by the International Accounting Standards Board (IASB). These financial statements have been prepared under the historical cost
basis except for assets and liabilities measured at fair value. The accounting policies have been consistently applied except for the
adoption of the new standards and interpretations detailed on the following pages.
The functional currency of the Company and certain of its subsidiaries is US dollar, which is the currency of the primary economic
environment in which the entities operate. All amounts are presented in US dollar and rounded to the nearest thousand. The financial
results of subsidiaries whose functional and reporting currency is in currencies other than US dollar have been converted into US dollar
on the basis as set out in Note 1.2.14, Foreign currency translations.
The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires
management to exercise its judgement in the process of applying the Group’s accounting policies. The areas involving a higher degree
of judgement or complexity, or areas where assumptions and estimates are significant to the financial statements, are disclosed in Note
1.2.26, Critical accounting estimates and judgements.
Changes in accounting policies and disclosures
New and amended standards and interpretations
The Group adopted certain standards and amendments for the first time, which became effective for the Group on 1 January 2023 and

1.2 Summary of material accounting policies (continued)
1.2.2 Going concern
The Group’s business activities, together with the factors likely to affect its future development, performance and position have been
assessed by management. The financial position of the Group, its cash flows and liquidity position are presented in the Annual Report
and Accounts. In addition, Note 25, Financial risk management, includes the Group’s objectives, policies and processes for managing its
capital; its financial risk management objectives; details of its financial instruments; and its exposures to market risk, credit risk and
liquidity risk.
The Group’s net debt at 31 December 2023 was US$21.3 million (31 December 2022: net cash US$3.3 million). The Group’s available
undrawn facilities at 31 December 2023 amounted to US$45.9 million (31 December 2022: US$82.6 million), resulting in liquidity (defined
as net debt/cash and available undrawn facilities) of US$24.6 million (31 December 2022: US$85.9 million). The gross liquidity position of
the Group (defined as gross cash and available undrawn facilities) as at 31 December 2023 is US$62.4 million (31 December 2022:
US$91.3 million). The Group’s Revolving Credit Facilities (RCF), which total US$71.0 million when fully unutilised, mature on 22
December 2024. In addition, there is a US$5.5 million general banking facility with no set expiry date, but is reviewed annually (Refer
Note 16, Interest-bearing loans and borrowings).The impacts on future cash flows of Eskom’s continued electricity outages, the current
diamond market conditions, the ongoing Russian invasion on Ukraine and the conflict in Gaza, were considered by performing
sensitivities on costs, diamond pricing and the unlikely weakening of the US dollar against the Lesotho loti.
The Group’s RCFs mature on 22 December 2024. The existing facility agreement includes an option to extend the facilities for a period
of 24 months (subject to lender approval). The Group may also decide to renew these facilities for a potentially longer period of 36
months. These facilities have been in place since 2011 and have been renewed on three previous occasions through expanding the
lender group and increasing the overall facility amount. The Directors believe that in considering the future cash flows, the long-
standing relationships with the wider lender group and the history of the successful renewals of the facilities, it is more than likely that
the facilities be extended or renewed during 2024. In the unlikely event that the RCFs are not renewed, the Directors believe that various
mitigation actions such as the deferment or further optimisation of waste stripping activities could be implemented in the short term.
After making enquiries which include reviews of forecasts and budgets, timing of cash flows and sensitivity analyses, the Group’s
operations and production levels, the various cost reduction initiatives and considering the likely successful renewal of the Group’s
RCFs, the Directors have a reasonable expectation that the Group has adequate financial resources without the use of mitigating
actions to continue in operational existence for the foreseeable future. For this reason, the Directors continue to adopt the going
concern basis in preparing the Group Financial Statements.
These financial statements have been prepared on a going concern basis which assumes that the Group will be able to meet its
liabilities as they fall due for the foreseeable future.
1.2.3 Basis of consolidation
The consolidated financial statements incorporate the financial statements of the Company and entities controlled by the Company as
at 31 December 2023.
Subsidiaries
Subsidiaries are consolidated from the date of their acquisition, being the date on which the Group obtains control, and continue to be
consolidated until the date that such control ceases. An investor controls an investee when it is exposed, or has rights, to variable
returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. To meet
the definition of control in IFRS 10, all three of the following criteria must be met: (a) an investor has power over an investee; (b) the
investor has exposure, or rights, to variable returns from its involvement with the investee; and (c) the investor has the ability to use its
power over the investee to affect the amount of the investor’s returns. The financial statements of subsidiaries used in the preparation of
the consolidated financial statements are prepared for the same reporting year as the parent company and are based on consistent
accounting policies. All intra-group balances and transactions, including unrealised gains and losses arising from them, are eliminated in
full.
Non-controlling interests
Non-controlling interests represent the equity in a subsidiary not attributable, directly or indirectly, to the parent company and is
presented separately within equity in the consolidated statement of financial position, separately from equity attributable to owners of
the parent. Losses within a subsidiary are attributed to the non-controlling interest even if that results in a deficit balance.
1.2.4 Exploration and evaluation expenditure
Exploration and evaluation activity involves the search for mineral resources, the determination of technical feasibility and the
assessment of commercial viability of an identified resource. Exploration and evaluation activity includes:
• acquisition of rights to explore;
• researching and analysing historical exploration data;
• gathering exploration data through topographical, geochemical and geophysical studies;
• exploratory drilling, trenching and sampling;
• determining and examining the volume and grade of the resource;
• surveying transportation and infrastructure requirements; and
• conducting market and finance studies.

1. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued)
1.2 Summary of material accounting policies (continued)
1.2.4 Exploration and evaluation expenditure (continued)
Administration costs that are not directly attributable to a specific exploration area are charged to the statement of profit or loss.
Licence costs paid in connection with a right to explore in an existing exploration area are capitalised, as mining assets within property,
plant and equipment, and amortised over the term of the permit.
Exploration and evaluation expenditure is capitalised as incurred. Capitalised exploration expenditure is recorded as a component of
property, plant and equipment, as an exploration and development asset, at cost less accumulated impairment charges. As the asset is
not available for use, it is not depreciated.
All capitalised exploration and evaluation expenditure is monitored for indications of impairment. Where a potential impairment is
indicated, assessments are performed for each area of interest in conjunction with the group of operating assets (representing a cash-
generating unit (CGU)) to which the exploration is attributed. To the extent that exploration expenditure is not expected to be
recovered, it is charged to the statement of profit or loss. Exploration areas where reserves have been discovered, but require major
capital expenditure before production can begin, are continually evaluated to ensure that commercial quantities of reserves exist or to
ensure that additional exploration work is under way as planned.
Management is required to make certain estimates and judgements when determining whether the commercial viability of an identified
resource has been met and when determining whether indicators of impairment exist.
1.2.5 Development expenditure
When proven and probable reserves are determined and development is sanctioned, capitalised exploration and evaluation
expenditure is reclassified from exploration phase to development phase. As the asset is not available for use, during the development
phase, it is not depreciated. On completion of the development phase, any capitalised exploration and evaluation expenditure already
capitalised to a development asset, together with the subsequent development expenditure, is reclassified within property, plant and
equipment to mining assets and depreciated on the basis as laid out in Note 1.2.6, Property, plant and equipment.
All development expenditure is monitored for indicators of impairment annually. Management is required to make certain estimates
and judgements when determining whether indicators of impairment exist.
1.2.6 Property, plant and equipment
Property, plant and equipment is recorded at cost less accumulated depreciation and accumulated impairment losses. Cost includes
expenditure that is directly attributable to the acquisition and construction of the items, to get the asset in its condition and location for
its intended use among others, professional fees, and for qualifying assets, borrowing costs capitalised in accordance with the Group’s
accounting policies.
Subsequent costs to replace a component of an item of property, plant and equipment that is accounted for separately, is capitalised
when the cost of the item can be measured reliably, with the carrying amount of the original component being written off. All repairs
Depreciation commences when an asset is available for use. Depreciation is charged so as to write off the depreciable amount of the
asset to its residual value over its estimated useful life, using a method that reflects the pattern in which the asset’s future economic
benefits are expected to be consumed by the Group.
Item Method Useful life
Mining assets Straight line Lesser of life of mine or period of mining lease
Decommissioning assets Straight line Lesser of life of mine or period of mining lease
Leasehold improvements Straight line Three years or lesser of life of mine or period of mining lease
Plant and equipment Straight line; units of production Three to 15 years; machine hours
Other assets Straight line Two to eight years
An item of property, plant and equipment and any significant part initially recognised is derecognised upon disposal (ie, at the date the
recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on
derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is
included in the statement of profit or loss when the asset is derecognised.
The asset’s residual values, useful lives and methods of depreciation are reviewed annually. Changes in the expected residual values,
expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are considered to
modify the depreciation period or method, as appropriate, and are treated as changes in accounting estimates, and adjusted for
prospectively, if appropriatee.

1.2.6 Property, plant and equipment (continued)
Pre-production and in production stripping costs
Costs associated with removal of waste overburden are classified as stripping costs.
Stripping activities that are undertaken during the production phase of a surface mine may create two benefits, being either the
production of inventory or improved access to the ore to be mined in the future. Where the benefits are realised in the form of inventory
produced in the period, the production stripping costs are accounted for as part of the cost of producing those inventories. Where
production stripping costs are incurred and where the benefit is the creation of mining flexibility and improved access to ore to be
mined in the future, the costs are recognised as a non-current asset if:
(a) future economic benefits (being improved access to the orebody) are probable;
(b) the component of the orebody for which access will be improved can be accurately identified; and
(c) the costs associated with the improved access can be reliably measured.
The non-current asset recognised is referred to as a “stripping activity asset” and is separately disclosed in Note 8, Property, plant and
equipment. If all the criteria are not met, the production stripping costs are charged to the statement of profit or loss as operating costs.
The stripping activity asset is initially measured at cost, which is the accumulation of costs directly incurred to perform the stripping
activity that improves access to the identified component of ore, plus an allocation of directly attributable overhead costs.
If incidental operations are occurring at the same time as the production stripping activity, but are not necessary for the production
stripping activity to continue as planned, these costs are not included in the cost of the stripping activity asset. Given the deep vertical
nature of the pit, all stripping costs are capitalised on a cut/component basis for each cut in the mine planning process.
The stripping activity asset is subsequently amortised over the expected useful life of the identified component of the orebody that
became more accessible as a result of the stripping activity. The net book value of the stripping asset and future expected stripping
costs to be incurred for that component is depreciated using the units of production over the proven and probable reserves, in order to
match the total stripping costs of the cut to the economic benefits created by the cut. As a result, the stripping activity asset is carried at
cost less amortisation and any impairment losses. The future stripping costs of the cut/component and the expected ore to be mined of
that cut/component are recalculated annually in light of additional knowledge and changes in estimates. Changes in the stripping ratio
are accounted for prospectively as a change in estimate.
Management applies judgement to calculate and allocate the production stripping costs to inventory and/or the stripping activity
asset(s) as referred under Note 1.2.26, Critical accounting estimates and judgements.
1.2.7 Borrowing costs
Borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset that necessarily takes a
substantial period of time to get ready for its intended use or sale are capitalised as part of the cost of the asset. All other borrowing
costs are expensed in the period in which they occur. Borrowing costs consist of interest and other costs that an entity incurs in
connection with the borrowing of funds.
1.2.8 Goodwill
Goodwill is initially measured at cost, being the excess of the aggregate of the acquisition date fair value of the consideration
transferred and the amount recognised for the non-controlling interest (and where the business combination is achieved in stages, the
acquisition date fair value of the acquirer’s previously held equity interest in the acquiree) over the fair value of the net identifiable
amounts of the assets acquired and the liabilities assumed in the business combination.
Assets acquired and liabilities assumed in transactions separate to the business combinations, such as the settlement of pre-existing
relationships or post-acquisition remuneration arrangements, are accounted for separately from the business combination in
accordance with their nature and applicable IFRS.
Identifiable intangible assets, meeting either the contractual legal or separability criterion are recognised separately from goodwill.
Contingent liabilities representing a present obligation are recognised if the acquisition date fair value can be measured reliably.
If the aggregate of the acquisition date fair value of the consideration transferred and the amount recognised for the non-controlling
interest (and where the business combination is achieved in stages, the acquisition date fair value of the acquirer’s previously held
equity interest in the acquiree) is lower than the fair value of the net identifiable amounts of the assets acquired and the liabilities
assumed in the business combination, the difference is recognised in profit and loss.
After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing,
goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group’s CGUs (or groups of CGUs)
that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to
those units. Each unit or group of units to which goodwill is allocated shall represent the lowest level within the entity at which the
goodwill is monitored for internal management purposes, and shall not be larger than an operating segment before aggregation.
Where goodwill forms part of a CGU and part of the operation within that unit is disposed of, the goodwill associated with the
operation disposed of is included in the carrying amount of the operation when determining the gain or loss on disposal of the
operation. Goodwill disposed of in this circumstance is measured based on the relative values of the operation disposed of and the
portion of the CGU retained.

1.2 Summary of material accounting policies (continued)
1.2.9 Financial instruments
The Group shall only recognise a financial instrument when the Group becomes a party to the contractual provisions of the instrument.
A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of
another entity.
Financial assets
Management determines the classification of its financial assets at initial recognition and re-evaluates this designation at every reporting
date based on the business model for managing these financial assets and the contractual cash flow characteristics. Currently the Group
only has financial assets at amortised cost which consist of receivables and other assets, and cash and short-term deposits which is held
within a business model to collect contractual cash flows and for which the contractual cash flow characteristics are solely payments of
principal and interest. When financial assets are recognised initially, they are measured at fair value plus (in the case of financial assets
not at fair value through profit or loss) directly attributable transaction costs. Purchases or sales of financial assets that require delivery of
assets within a timeframe established by regulation or convention in the marketplace (regular way trades) are recognised on the trade
date.
Financial assets at amortised cost
Financial assets at amortised cost are non-derivative financial assets with fixed or determinable payments that are not quoted in an
active market. They are included in current assets, except those with maturities greater than 12 months after the reporting date. These
are classified as non-current assets. Such assets are carried at amortised cost using the effective interest rate method, if the time value
of money is significant, less any allowance for impairment. Gains and losses are recognised in the statement of profit or loss when the
financial assets at amortised cost are derecognised or impaired, as well as through the amortisation process.
Derecognition
A financial asset is primarily derecognised when the rights to receive cash flows from the asset have expired or the Group has
transferred its rights to receive cash flows from the asset. Gains or losses from derecognition of financial assets are recognised in the
statement of profit or loss.
Financial liabilities
Financial liabilities are initially measured at fair value net of (in the case of financial liabilities not at fair value through profit or loss)
directly attributable transaction costs. The Group’s Interest-bearing loans and borrowings and trade and other payables financial
liabilities are subsequently stated at amortised cost using the effective interest rate method, with any difference between proceeds (net
of transaction costs) and the redemption value being recognised in the statement of profit or loss, unless capitalised in accordance with
Note 1.2.6, Property, plant and equipment, over the contractual period of the financial liability.
Derecognition
A financial liability is derecognised when the obligation under the liability is discharged or cancelled or expires. Gains or losses from
derecognition of financial liabilities are recognised in the statement of profit or loss.
1.2.10 Impairments
Non-financial assets
The Group assesses, at each reporting date, whether there is an indication that an asset (or CGU) may be impaired in accordance with
IAS 36. Goodwill is assessed for impairment on an annual basis and when circumstances indicate that the carrying value may be
impaired. An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount. The
recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. In assessing value in use, the estimated future
cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value
of money and the risks specific to the asset.
Non-financial assets that were previously impaired are reviewed for possible reversal of the impairment at each reporting date. A
previously recognised impairment loss is reversed only if there has been a change in the estimates used to determine the asset’s
recoverable amount since the last impairment loss was recognised. If that is the case, the carrying amount of the asset is increased to its
recoverable amount. That increased amount cannot exceed the carrying amount that would have been determined, net of depreciation,
had no impairment loss been recognised for the asset in prior years. Such a reversal is recognised in the statement of profit or loss. After
such a reversal the depreciation charge is adjusted in future periods to allocate the asset’s revised carrying amount, less any residual
value, on a systematic basis over its remaining useful life. Impairment losses relating to goodwill cannot be reversed in future periods.

1.2 Summary of material accounting policies (continued)
1.2.11 Inventories
Inventories, which include rough diamonds, ore stockpiles and consumables, are measured at the lower of cost and net realisable value.
The amount of any write-down of inventories to net realisable value and all losses, is recognised in the period the write-down or loss
occurs. Cost is determined as the average cost of production, using the weighted average method. Cost includes directly attributable
mining overheads, but excludes borrowing costs.
Net realisable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and the
estimated costs to be incurred in marketing, selling and distribution.
The Group maintains strategic stockpiles in line with operational and insurance requirements. In normal mining activities, lower grade
(highly diluted) ore is consequentially mined and maintained in a separate stockpile. Although this lower grade (highly diluted) stockpile
could be processed as emergency plant feed, it is likely that it will be processed at the end of life of mine. As a result, the associated
mining costs for this stockpile are allocated at the net realisable value and the balance of the costs are allocated to the Main pipe
strategic stockpiles.
1.2.12 Cash and cash equivalents
Cash and cash equivalents are carried in the statement of financial position at amortised cost. Cash and cash equivalents comprise cash
on hand, deposits held at call with banks, and other short-term, highly liquid investments with original maturities of three months or less
that are held to meet the Group's short-term cash commitments.
For the purpose of the consolidated statement of cash flows, cash and cash equivalents consist of cash and cash equivalents as defined
above, net of outstanding bank overdrafts which are repayable on demand and form an integral part of the Group's cash management.
1.2.13 Issued share capital
Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or options are shown in equity
as a deduction from the proceeds.
Treasury shares
Own equity instruments that are reacquired are recognised at cost, including transaction costs, and deducted from equity. These are
disclosed as treasury shares. No gain or loss is recognised in profit or loss in the purchase, sale, issue or cancellation of the Group’s own
equity instruments. Any difference between the carrying amount and the consideration, if reissued, is recognised in equity.
1.2.14 Foreign currency translations
Presentation currency
The results and financial position of the Group’s subsidiaries which have a functional currency different from the Group’s presentation
currency are translated into the Group’s presentation currency as follows:
• statement of financial position items are translated at the closing rate at the reporting date;
• income and expenses for each statement of profit or loss are translated at average exchange rates (unless this average is not a
reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and
expenses are translated at the dates of the transactions); and
• resulting exchange differences are recognised as a separate component of equity.
Details of the rates applied at the respective reporting dates and for the statement of profit or loss transactions are detailed in Note 15,
Issued share capital and reserves.
Transactions and balances
Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the
transactions. Foreign exchange gains or losses resulting from the settlement of such transactions and from the translation at the period-
end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the statement of profit or
loss. Non-monetary items that are measured in terms of cost in a foreign currency are translated using the exchange rates as at the
dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates
at the date when the fair value was determined. Monetary items for each statement of financial position presented are translated at the
closing rate at the reporting date.

1.2.15 Share-based payments
Employees (including senior executives) of the Group receive remuneration in the form of share-based payment transactions, whereby
employees render services as consideration for equity instruments (equity-settled transactions).
Equity-settled transactions
The cost of equity-settled transactions with employees are measured by reference to the fair value of the equity instruments at the date
at which they are granted and is recognised as an expense over the vesting period, which ends on the date on which the relevant
employees become fully entitled to the award. Fair value is determined using an appropriate pricing model. In valuing equity-settled
transactions, no account is taken of any vesting conditions, other than conditions linked to the price of the shares of the Company
(market conditions).
On a cumulative basis, over the vesting period of an award, no expense is recognised for awards that do not ultimately vest, except for
awards where vesting is conditional upon a market condition, which are treated as vesting irrespective of whether or not the market
condition is satisfied, provided that all other performance conditions are satisfied.
At each reporting date before vesting, the cumulative expense is calculated, representing the extent to which the vesting period has
expired and management’s best estimate of the achievement of the vesting conditions or otherwise of the non-market vesting
conditions and of the number of equity instruments that is expected to ultimately vest or, in the case of an instrument subject to a
market condition, be treated as vesting as described above. The movement in cumulative expense since the previous reporting date is
recognised in the statement of profit or loss, with a corresponding entry in equity.
Management applies judgement when determining whether share options relating to employees who resigned before the end of the
service condition period are cancelled or forfeited as referred under Note1.2.26, Critical accounting estimates and judgements.
The Group periodically releases the share-based equity reserve to retained earnings in relation to lapsed and forfeited options
subsequent to vesting dates.
1.2.16 Provisions
Provisions are recognised when:
• the Group has a present legal or constructive obligation as a result of a past event; and
• a reliable estimate can be made of the obligation.
Provisions are measured at the present value of the expenditures expected to be required to settle the obligation, using a pre-tax
discount rate that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in
the provision due to the passage of time is recognised as a finance cost.
1.2.17 Restoration and rehabilitation provision
The mining, extraction and processing activities of the Group normally give rise to obligations for site restoration and rehabilitation.
Rehabilitation works can include facility decommissioning and dismantling, removal and treatment of waste materials, land
rehabilitation, and site restoration. The extent of the work required and the estimated cost of final rehabilitation, comprising liabilities
for decommissioning and restoration, are based on current legal requirements, existing technology and the Group’s environmental
policies, and is reassessed annually. Cost estimates are not reduced by the potential proceeds from the sale of property, plant and
equipment.
Provisions for the cost of each restoration and rehabilitation programme are recognised at the time the environmental disturbance
occurs. When the extent of the disturbance increases over the life of the operation, the provision and associated asset is increased
accordingly. Costs included in the provision encompass all restoration and rehabilitation activity expected to occur. The restoration and
rehabilitation provisions are measured at the expected value of future cash flows, discounted to their present value, using a pre-tax
discount rate. Discount rates used are specific to the country in which the operation is located or reasonable alternatives if in-country
information is not available. The value of the provision is progressively increased over time as the effect of the discounting unwinds,
which is recognised in finance charges. Restoration and rehabilitation provisions are also adjusted for changes in estimates.
When provisions for restoration and rehabilitation are initially recognised, the corresponding cost is capitalised as a decommissioning
asset where it gives rise to a future benefit and depreciated over future production from the operation to which it relates.
Management is required to make significant estimates and assumptions when determining the amount of the restoration and
rehabilitation provisions as referred under Note 1.2.26, Critical accounting estimates and judgements.

1.2.18 Taxation
Income tax for the period comprises current and deferred tax. Income tax is recognised in the statement of profit or loss except to the
extent that it relates to items charged or credited directly to equity or to other comprehensive income, in which case the tax
consequences are recognised directly in equity and other comprehensive income respectively. Current tax expense is the expected tax
payable on the taxable income for the period, using tax rates enacted or substantively enacted at the reporting date, and any
adjustment to tax payable in respect of previous years.
Deferred tax is provided using the statement of financial position liability method, providing for temporary differences between the
carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes.
Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realised or the
liability is settled based on the tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.
A deferred tax asset is recognised only to the extent that it is probable that future taxable profits will be available against which the
asset can be utilised. Deferred tax assets are reduced to the extent that it is no longer probable that the related tax benefit will be
realised.
The Group offsets deferred income tax assets and deferred income tax liabilities if, and only if, it has a legally enforceable right to set off
current tax assets and current tax liabilities and the deferred income tax assets and deferred income tax liabilities relate to income taxes
levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current
tax liabilities and assets on a net basis, or to realise the assets and settle the liabilities simultaneously, in each future period in which
significant amounts of deferred tax liabilities or assets are expected to be settled or recovered.
In respect of taxable temporary differences associated with investments in subsidiaries, associates and jointly controlled entities,
deferred tax is provided except where the timing of the reversal of the temporary differences can be controlled by the Group and it is
probable that the temporary differences will not reverse in the foreseeable future.
In respect of deductible temporary differences associated with investments in subsidiaries, associates and jointly controlled entities,
deferred tax assets are only recognised to the extent that it is probable that the temporary differences will reverse in the foreseeable
future and taxable profit will be available against which the temporary differences can be utilised. Withholding tax is recognised in the
statement of profit or loss when dividends or other services which give rise to that withholding tax are declared or accrued respectively.
Withholding tax is disclosed as part of current tax.
Royalties
Royalties incurred by the Group comprise mineral extraction costs based on a percentage of sales paid to the local revenue authorities.
These obligations arising from royalty arrangements are recognised as current payables and disclosed as part of royalty and selling
costs in the statement of profit or loss.
Royalties and revenue-based taxes are accounted for under IAS 12 when they have the characteristics of an income tax. This is
considered to be the case when they are imposed under government authority and the amount payable is based on taxable income –
rather than based on quantity produced or as a percentage of revenue. For such arrangements, current and deferred tax is provided on
the same basis as described above for other forms of taxation. The royalties incurred by the Group are considered not to meet the
criteria to be treated as part of income tax.
1.2.19 Employee benefits
Provision is made in the financial statements for all short-term employee benefits. Liabilities for wages and salaries, including non-
monetary benefits, benefits required by legislation, annual leave, retirement benefits and accumulating sick leave obliged to be settled
within 12 months of the reporting date, are recognised in trade and other payables and are measured at the amounts expected to be
paid when the liabilities are settled. Benefits falling due more than 12 months after the reporting date are measured at the amount the
obligation is expected to be settled or discounted to present value using a pre-tax discount rate where relevant or where time value of
money is expected to be significant. The Group recognises an expense for contributions to the defined contribution pension fund in the
period in which the employees render the related service.
Bonus plans
The Group recognises a liability and an expense for bonuses. The Group recognises a liability where contractually obliged or where
there is a past practice that has created a constructive obligation. These liabilities are recognised in trade and other payables and are
measured at the amounts expected to be paid when the liabilities are settled.

1.2 Summary of material accounting policies (continued)
1.2.20 Leases
At inception, the Group assesses whether a contract is or contains a lease. This assessment involves the exercise of judgement whether
it depends on a specified asset, whether the Group obtains substantially all the economic benefits from the use of that asset, and
whether the Group has the right to direct the use of the asset. For leases that contain one lease component and one or more additional
lease or non-lease components, the Group allocates the consideration in the contract to each lease and non-lease component on the
basis of the individual relative stand-alone price of all lease and non-lease components and the aggregate stand-alone price of all lease
and non-lease components. The lease component is accounted for under the requirements of IFRS 16 and the non-lease component is
accounted for using the relevant IFRS standard based on the nature of the non-lease component.
Right-of-use assets
The Group recognises right-of-use assets at the commencement date of the lease (ie, the date the underlying asset is available for use).
Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any
remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognised, initial direct costs
incurred, costs to dismantle, restore and remove the right-of-use asset, and lease payments made at or before the commencement date
less any lease incentives received. After the commencement date, the right-of-use assets are measured using a cost model. Right-of-use
assets are depreciated on a straight-line basis over the shorter of the lease term and the estimated useful lives of the assets. If
ownership of the leased asset transfers to the Group at the end of the lease term or the cost reflects the exercise of a purchase option,
depreciation is calculated using the estimated useful life of the asset. Right-of-use assets are subject to impairment. Refer Note 1.2.10,
Impairments.
Lease liabilities
At the commencement date of the lease, the Group recognises lease liabilities measured at the present value of lease payments to be
made over the lease term. The lease payments include fixed payments (including in-substance fixed payments) less any lease incentives
receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value
guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group
and payments of penalties for terminating a lease, if the lease term reflects the Group exercising the option to terminate. The variable
lease payments that do not depend on an index or a rate are recognised as an expense in the period on which the event or condition
that triggers the payment occurs.
In calculating the present value of lease payments, the Group uses the incremental borrowing rate at the lease commencement date if
the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is
increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease
liabilities is remeasured if there is a modification to the terms and conditions of the lease or if there is a lease reassessment.
Short-term leases and leases of low-value assets
The Group applies the short-term lease recognition exemption to its short-term leases (ie, those leases that have a lease term of
12 months or less from the commencement date and do not contain a purchase option). It also applies the lease of low-value assets
recognition exemption to leases of office equipment that are considered to be qualitatively and quantitatively of low value. Lease
payments on short-term leases and leases of low-value assets are recognised as expense on a straight-line basis over the lease term.
Group as a lessor
Where the Group is a lessor, it determines at inception whether the lease is a finance or operating lease. When a lease transfers
substantially all the risks and rewards of ownership of the underlying asset then the lease is a finance lease; otherwise the lease is an
operating lease.
Where the Group is an intermediate lessor, the interest in the head lease and the sub-lease is accounted for separately and the lease
classification of a sub-lease is determined by reference to the Right-of-use-asset arising from the head lease. Income from operating
leases is recognised on a straight-line basis over the lease term.

1.2 Summary of material accounting policies (continued)
1.2.21 Revenue from contracts with customers
Revenue comprises net invoiced diamond sales to customers excluding VAT. Diamond sales are made through a competitive tender
process and recognised when the Group’s performance obligations have been satisfied at the time the buyer obtains control of the
diamond(s), at an amount that the Group expects to be entitled in exchange for the diamond(s). Where the Group makes rough
diamond sales to customers and retains a right to an interest in their future sale as polished diamonds, the Group records the sale of the
rough diamonds but such contingent revenue on the onward sale is only recognised at the date when the polished diamonds are sold
or when polished sales prices are mutually agreed between the customer and the Group.
The following revenue streams are recognised:
• rough diamonds which are sold through a competitive tender process, partnership agreements and joint operation arrangements;
• polished diamonds and other products which are sold through direct sales channels;
• additional uplift (on the value from rough to polished) on partnership arrangements; and
• additional uplift (on the value from rough to polished) on joint operation arrangements.
The sale of rough diamonds is the core business of the Group, with other revenue streams contributing marginally to total revenue.
Revenue through partnership arrangements is recognised for the sale of the rough diamond, with an additional uplift based on the
polished margin achieved. Management recognises the revenue on the sale of the rough diamond when it is sold to a third party, as
there is no continuing involvement by management in the cutting and polishing process and control has passed to the third party.
Revenue from additional uplift is considered to be a variable consideration. This variable consideration will generally be significantly
constrained. This is on the basis that the ultimate additional uplift received will depend on a range of factors that are highly susceptible
to factors outside the Group’s influence. Management recognises revenue on the additional uplift when the polished diamond is sold
by the third party or the polished sales prices are mutually agreed between the third party and the Group and the additional uplift is
guaranteed, as this is the point in time at which the significant constraints are lifted or resolved from the Polished Margin revenue.
Rendering of services
Revenue from services relating to third-party diamond manufacturing is recognised in the accounting period in which the services are
rendered, when the Group’s performance obligations have been satisfied, at an amount that the Group expects to be entitled to in
exchange for the services.
1.2.22 Interest income
Interest income is recognised on a time proportion basis using the effective interest rate method.
1.2.23 Dividend income
Dividend income is recognised when the amount of the dividend can be reliably measured and the Group’s right to receive payment is
established.
1.2.24 Finance costs
Finance costs are recognised on a time proportion basis using the effective interest rate method.
1.2.25 Dividend distribution
Dividend distributions to the Group’s shareholders are recognised as a liability in the Group’s financial statements in the period in which
the dividends are approved by the Group’s shareholders.
1.2.26 Critical accounting estimates and judgements
The preparation of the consolidated financial statements requires management to make estimates and judgements and form
assumptions that affect the reported amounts of the assets and liabilities, the reported income and expenses during the periods
presented therein, and the disclosure of contingent liabilities at the date of the financial statements. Estimates and judgements are
continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed
to be reasonable under the circumstances.
The Group makes estimates and assumptions concerning the future and the resulting accounting estimates will, by definition, seldom
equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the
financial results or the financial position reported in future periods are discussed below.
Business environment and country risk
The Group’s operations are subject to country risk being the economic, political and social risks inherent in doing business in certain
areas of Africa, Europe and the United Kingdom. These risks include matters arising out of the policies of the government, economic
conditions, imposition of or changes to taxes and regulations, foreign exchange rate fluctuations and the enforceability of contract
rights.
The consolidated financial information reflects management’s assessment of the impact of these business environments and country
risks on the operations and the financial position of the Group. The future business environment may differ from management’s
assessment.

1.2.26 Critical accounting estimates and judgements (continued)
Task Force on Climate-related Financial Disclosures (TCFD)
In preparing the Consolidated Financial Statements management continues to consider the impact of climate change, particularly in the
context of the disclosures included in the Strategic Report detailing the now implemented TCFD requirements and the high level
overview of some climate-related risks and opportunities. These considerations did not have a material impact on the financial reporting
estimates and judgements, consistent with the assessment that climate change is not expected to have a significant impact on the
Group’s going concern assessment to March 2025, after which management will assess the impact on the Group’s going concern. These
considerations also had no material impact on any Property, Plant and Equipment or Commitments. For Letšeng, the physical risks
identified of severe weather conditions, are similar to its current operating conditions of drought, high wind, snow and rainfall. The
operation is therefore well set up to manage these conditions within its current reporting and accounting framework. As users of grid-
supplied and fossil fuel energy, our short-term focus is on improving energy efficiencies in our operational processes and on reducing
fossil fuel use. Due to the uncertainty of the cost and timing of implementation of carbon-related taxes, the impact of such taxes on the
Group’s operations and cash flows has been excluded from the going concern, viability assessment and impairment review.
The ongoing Russian invasion of Ukraine and the conflict in Gaza
The supply chain challenges caused by the ongoing Russian invasion of Ukraine has significantly increased the price of consumables,
especially diesel and explosive costs used in the mining activities, and inflation rates across the jurisdictions where the Group operates.
The slowdown of global economic growth in 2023 was further impacted by the conflict in Gaza that began in October 2023 and the
subsequent attacks launched by Yemen’s Houthi rebels on cargo vessels in the Red Sea at the start of 2024. The diamond industry has
suffered in the face of these challenges. Management has incorporated the impact of the current and historical diamond prices,
increased costs and current inflation when assessing its future cash flows.
Insourcing of the mining activities
Matekane Mining Investment Company (Proprietary) Limited (MMIC) has been the provider of mining services to Letšeng since 2005.
Following the election of Mr Sam Matekane (the ultimate owner of MMIC) as Prime Minister of Lesotho in October 2022, Letšeng
carefully considered its options to resolve the potential conflict of interest created by being in a business relationship with a politically
exposed person. This transition to owner mining further creates an opportunity for Letšeng to maximise mining efficiencies, reduce
costs through eliminating contractor margins, manage mining procurement directly and enables further flexibility in the planning and
execution of its mining activities. All these factors will contribute to a more efficient and cost effective operation. Effective 1 December
2023, Letšeng reached agreement with MMIC to early terminate the mining equipment and service lease contract, eleven months ahead
of its scheduled contractual end date (31 October 2024) without any termination penalties and insourced these activities. Letšeng
acquired the mining fleet and support equipment that was used exclusively for Letšeng, and offered employment to those MMIC
employees working exclusively for Letšeng, in line with operational requirements, effective 1 February 2024. The MMIC employees
remained as contract workers from 1 December 2023.
The total purchase price, which was determined with the assistance of external third-party valuators,was US$22.7 million. A payment
mechanism was agreed whereby US$13.0 million was paid on 1 December 2023, the effective date, US$9.3 million was paid in January
2024, and a retainer of US$0.4 million, withheld for equipment under repair was paid in early March 2024. The US$9.7 million portion of
the purchase price not settled in cash on the effective date of the acquisition has been presented as part of current trade and other
payables in the consolidated statement of financial position.
In assessing whether this transaction met the criteria of an asset acquisition or a business combination, the criteria set out in IFRS 3
Business Combinations was considered. Management opted to apply the optional test, being a concentration test, which permits a
simplified quantitative assessment of whether an acquired set of activities and assets is not a business. Based on the results from the
concentration test, the Group concluded that the acquisition is not a business combination but rather an asset acquisition due to
substantially all the fair value of the gross assets acquired being concentrated into a group of similar identifiable assets which are the
same in nature and exposed to the same risk in terms of managing and creating outputs from the mining activities at Letšeng. The total
purchase price was allocated to all the identifiable IAS 16 Property, plant and equipment assets acquired on the basis of their relative
fair values at the effective date of the acquisition. The capitalised total purchase price has been disclosed as additions within Note 8,
Property, plant and equipment mainly within the plant and equipment category amounting to US$22.7 million. Directly attributable
transaction costs of US$0.1 million were allocated to all of the individual identifiable IAS 16 Property, plant and equipment assets
acquired on the basis of their relative fair values at the effective date of the acquisition. These assets will be depreciated over the useful
life of each asset based on the available production hours. The financial results for 31 December 2023 includes one month of
depreciation. The US$13.0 million portion of the purchase price and the directly attributable transaction costs of US$0.1 million that
were settled in cash during the current financial reporting period have been presented in the purchase of property, plant and
equipment line item within cash flows used in investing activities.

1.2 Summary of material accounting policies (continued)
1.2.26 Critical accounting estimates and judgements (continued)
Estimates
Ore reserves and associated life of mine (LoM)
There are numerous uncertainties inherent in estimating ore reserves and the associated LoM. Therefore, the Group must make a
number of assumptions in making those estimations, including assumptions as to the prices of diamonds, exchange rates, production
costs and recovery rates. Assumptions that are valid at the time of estimation may change significantly when new information becomes
available. Changes in the forecast prices of diamonds, exchange rates, production costs or recovery rates may change the economic
status of ore reserves and may, ultimately, result in the ore reserves being restated. Where assumptions change the LoM estimates, the
associated depreciation rates, residual values, waste stripping and amortisation ratios, and environmental provisions are reassessed to
take into account the revised LoM estimate. Refer Note 8, Property, plant and equipment, Note 10, Intangible assets and Note 20,
Provisions.
Provision for restoration and rehabilitation
Significant estimates and assumptions are made in determining the amount of the restoration and rehabilitation provisions. These deal
with uncertainties such as changes to the legal and regulatory framework, magnitude of possible contamination, and the timing, extent
and costs of required restoration and rehabilitation activity. Refer Note 20, Provisions, for further detail.
Judgement
Impairment reviews
The Group determines if goodwill is impaired at least on an annual basis, while all other significant operations are tested for impairment
when there are potential indicators which may require impairment review. This requires an estimation of the recoverable amount of the
relevant CGU under review. Recoverable amount is the higher of fair value less costs to sell and value in use. While conducting an
impairment review of its assets using value-in-use impairment models, the Group exercises judgement in making assumptions about
future rough diamond prices, volumes of production, ore reserves and resources included in the current LoM plans, production costs
and macro-economic factors such as inflation and discount rates. Changes in estimates used can result in significant changes to the
consolidated statement of profit or loss and consolidated statement of financial position. Refer Note 11, Impairment testing, for further
estimates and judgements applied.
The key assumptions used in the recoverable amount calculations, determined on a value-in-use basis, are listed below:
Valuation basis
Discounted present value of future cash flows.
LoM and recoverable value of reserves and resources
Economically recoverable reserves and resources, carats recoverable and grades achievable are based on management’s expectations
of the availability of reserves and resources at mine sites and technical studies undertaken by in-house and third-party specialists.
Reserves remaining after the current LoM plan have not been included in determining the value in use of the operations. The LoM of
Letšeng is to 2038 (2022: 2040). The earlier life was mainly as a result of a redesign of the Main pit.
Cost and inflation rate
Operating costs for Letšeng are determined based on management’s experience and the use of contractors over a period of time
whose costs are fairly reasonably determinable. Mining costs have been based on owner-mining assumptions and estimates, following
the insourcing of the mining activities, and are lower than in the past due to an immediate saving of contractor margin costs. Processing
costs in the short term have been based on historical trends and agreements with relevant contractors. More recently there has been a
significant focus on cost efficiencies in the processing plants, which have yielded positive results consistently for two months. These
costs have been reduced to recently achieved levels from 2025. In the longer term, management has applied local inflation rates of 5.0%
(2022: 5.0%) for operating costs beyond 2026. Up to 2026, inflation rates applied ranged between 5.4% – 8.9% (2022: 5.5% - 8.9%).
Capital costs for the first five years have been based on management’s capital programme after which a fixed percentage of operating
costs has been applied to determine the capital costs necessary to maintain current levels of operations.
Exchange rates
Exchange rates are applied in line with IAS 36, Impairment of Assets. The US dollar/Lesotho loti (LSL) exchange rate used was
determined with reference to the closing rate at 31 December 2023 of LSL18.29 (31 December 2022: LSL17.02).
Diamond prices
The short and medium-term diamond prices used in the impairment test have been set with reference to historical and recent prices
achieved, recent market trends and anticipated market supply and the Group’s medium-term forecast. Long-term diamond price
escalation reflects the Group’s assessment of market supply/demand fundamentals.
Discount rate
The discount rate of 10.4% for revenue (2022: 12.5%) and 12.4% for costs (2022: 15.4%) used for Letšeng represents the before-tax risk-
free rate adjusted for market risk, volatility and risks specific to the asset and its operating jurisdiction.

Market capitalisation
In the instance where the Group’s asset carrying values exceed market capitalisation, this results in an indicator of impairment. The
Group believes that this position does not represent an impairment as all significant operations were assessed for impairment during
the year and no impairments were recognised.
Sensitivity
The value in use for Letšeng indicated sufficient headroom, and the further changes to key assumptions which could result in
impairment are disclosed in Note 11, Impairment testing.
Provision for restoration and rehabilitation and deferred tax thereon
Judgement is applied when calculating the closure costs associated with the restoration of the Letšeng mine site. These include the
following:
• there are no costs associated with the backfill of the open pits due to no in-country legislation requirements;
• concurrent rehabilitation of the waste rock dump and residue storage facilities will take place during the operational phase; and
• there are no costs associated with dismantling permanent buildings as these will be handed over to various parties in consultation
with the Lesotho Government when the end of life is reached.
At the Ghaghoo mine site, the following judgements were applied:
• the mine site will be left in a state which could enable a future operator to operate on the site, and therefore certain infrastructure,
such as access roads to the mine, paving and walkways, a new solar solution installation, borehole pump and water treatment plant,
will remain intact and, after obtaining the necessary approvals, it will be handed over to the Government of Botswana through the
Ministry of Minerals and Energy. Therefore, no costs associated with the rehabilitation of certain roads or rehabilitation and
dismantling of certain infrastructures; and
• the timing of the rehabilitation cost cash flows has been estimated to be five years.
At Letšeng, deferred tax assets are recognised on provisions for rehabilitation as management will ensure appropriate tax planning to
ensure sufficient taxable income is available to utilise all deductions in the future. At Ghaghoo, no deferred tax assets have been
recognised on the provision for rehabilitation as management does not foresee any taxable profits or taxable temporary differences
against which the deferred tax asset can be utilised due to the operation being under care and maintenance.
Capitalised stripping costs (deferred waste)
Waste removal costs (stripping costs) are incurred during the development and production phases at surface mining operations. The
orebody needs to be identified in its various separately identifiable components. An identifiable component is a specific volume of the
orebody that is made more accessible by the stripping activity. Judgement is required to identify and define these components
(referred to as “cuts”), and also to determine the expected volumes (tonnes) of waste to be stripped and ore to be mined in each of
these components. These assessments are based on a combination of information available in the mine plans, specific characteristics of
the orebody and the milestones relating to major capital investment decisions.
Judgements and estimates are also used to apply the amortisation rate, future stripping costs of the cut/component and the expected
ore to be mined of that cut/component. Refer Note 8, Property, plant and equipment.
Share-based payments
Judgement is applied by management in determining whether the share options relating to employees who resigned before the end of
the service condition period have been cancelled or forfeited in light of their leaving status. Where employees do not meet the
requirements of a good leaver as per the rules of the long-term incentive plan (LTIP), no award will vest and this will be treated as
cancellation by forfeiture. The expenses relating to these charges previously recognised are then reversed. Where employees do meet
the requirements of a good leaver as per the rules of the LTIP, some or all of an award will vest and this will be treated as a modification
to the original award. The future expenses relating to these awards are accelerated and recognised as an expense immediately. Refer
Note 26, Share-based payments, for further detail.

Identifying uncertainties over tax treatments
As previously disclosed, an amended tax assessment was issued to Letšeng by the Revenue Services Lesotho (RSL), in December 2019,
contradicting the application of certain tax treatments in the current Lesotho Income Tax Act 1993. An objection to the amended tax
assessment was lodged with the RSL in March 2020, which was supported by the opinion of senior counsel. The RSL subsequently
lodged a court application for the review and setting aside of the applicable regulations to the Lesotho High Court pertaining to this
matter, which Letšeng is opposing. The amended court application process will continue during 2024, with support from senior legal
counsel.
Management do not believe an uncertain tax position exists as:
• there is no ambiguity in the application of the published Lesotho Income Tax Act;
• there has been no change in the application of the Income Tax Act and resulting tax; and
• senior counsel advice, which is legally privileged, has been obtained for the new circumstances. This advice still reflects good
prospects of success.
No provision or contingent liability, relating to
• the amended tax assessment in question; or,
• any potential legal costs that could be incurred should the matter be found in favour of the RSL has been raised in the 2023 Annual
Financial Statements.
Offsetting of deferred tax assets and deferred tax liabilities of the Group’s subsidiary, Letšeng Diamonds
The Group’s subsidiary, Letšeng Diamonds, is subject to the tax laws and regulations enacted within Lesotho. The corporate tax laws
and regulations currently enacted by the RSL requires a taxpayer to file a claim for offsetting current tax asset and current tax liabilities,
and offsetting deferred tax assets and deferred tax liabilities with the Commissioner within four years after service of the notice of
assessment for the year of assessment to which the claim relates.
The Group, after applying significant judgement, is of the view that Letšeng Diamonds does not have a legal enforceable right to offset
current tax assets against current tax liabilities, and deferred tax assets against deferred tax liabilities within the Lesotho corporate tax
jurisdiction as it is subject to the Commissioner’s approval of the claim submitted for which the outcome is highly uncertain as the
approval is purely subject to the discretion of the Commissioner. On this basis, the Group does not offset Letšeng Diamonds deferred
tax assets and deferred tax liabilities, but rather presents them on a gross basis in the consolidated statement of financial position. Refer
Note 1.2.18, Taxation.
Equipment and service lease
Prior to the insourcing of Letšeng’s mining activities on 1 December 2023, these activities were outsourced to a mining contractor,
MMIC, that performed these functions using their own equipment. Management applied judgement when evaluating whether the
contract between Letšeng and MMIC contained a lease. While it was concluded there was a lease, lease payments were variable in
nature as the lease payments varied based on the tonnes of ore and waste mined and hence no right of use asset or liability could be
measured. From the beginning of the current year until 1 December 2023, a portion of the lease payment was expensed in the
consolidated statement of profit or loss, and the portion relating to waste removal/stripping costs was capitalised to the waste stripping
asset in the proportions referred to under the estimate and judgements applied to the capitalised stripping costs (deferred waste)
above. Refer Note 1.2.26, Critical accounting estimates and judgements, Capitalised stripping costs (deferred waste) and Note 23,
Commitments and contingencies.

Plant and equipment mainly comprise back-up power generating equipment utilised at Letšeng. Motor vehicles mainly comprise
vehicles utilised by contractors at Letšeng. Buildings comprise office buildings in Maseru, Antwerp, London, Gaborone and
Johannesburg.
Right-of-use assets are depreciated on a straight-line basis over the shorter of its estimated useful life and the lease term.
During the year, Gem Diamonds Limited entered into a new contract for the rental of its London office space as the original lease came
to an end. At Letšeng, the lease contract for certain assets relating to blasting services was renegotiated resulting in the recognition of
associated right-of-use assets and lease liabilities. The original contract was cancelled and all associated assets and liabilities were
derecognised. Furthermore, two new contracts were entered into for the rental of earth-moving equipment and certain assets relating
to catering, housekeeping and laundry services. Both contracts were assessed as containing a lease resulting in the recognition of the
new associated right-of-use assets and lease liabilities. Refer Note 17, Lease liabilities.
During the prior year, a new lease contract for back-up power generating equipment at Letšeng was entered into resulting in the
recognition of right-of-use assets and lease liabilities associated with the new lease. Furthermore, Gem Diamonds Marketing Services
and Baobab Technologies entered into new contracts for the rental of office space in Antwerp as the original contracts both came to an
end. The new contracts were assessed as containing leases, which resulted in the recognition of the new associated right-of-use assets
and lease liabilities. Refer Note 17, Lease liabilities and Note 22.1, Cash generated by operations.
Total gains of US$30 thousand (2022: nil) have been recognised in the consolidated statement of profit or loss relating to the
derecognition of leases in the Group during the year. Refer Note 17, Lease liabilities and Note 22.1, Cash generated by operations.
During the year the Group recognised income of US$0.3 million (2022: US$0.3 million) from the sub-leasing of office buildings in Maseru.
The Group expects to receive the following lease payments from the operating sub-leasing in future years in line with current lease
terms:

11. IMPAIRMENT TESTING
Goodwill impairment testing is undertaken on Letšeng Diamonds annually and when there
are indications of impairment. The most recent test was undertaken at 31 December 2023. In
assessing whether goodwill has been impaired, the carrying amount of Letšeng Diamonds is
compared with its recoverable amount. For the purpose of goodwill impairment testing in
2023, the recoverable amount for Letšeng Diamonds has been determined based on a value
in use model, similar to that adopted in the past.

Value in use
The mining lease period at Letšeng extends to 2029 with an exclusive option to renew for a further 10 years to 2039. The latest open pit
mine plan which has been used to project the cash flows, reflects that the open pit mining (including inferred resources) is expected to
cease in 2038 (31 December 2022: 2040). In terms of IAS 36, cash flows are projected for a period up to the date of the life of mine plan
period, ie 2038, as it is earlier than the ceasing of the current mining lease period of 2039. During the prior period the IAS 36 cash flows
were projected for a period up to the end of the mining lease period of 2039 as it was earlier than the life of mine plan period which was
up to 2040. The mine plan takes into account the available reserves and other relevant inputs such as diamond pricing, costs and
geotechnical parameters. It includes the next open pit cutback in the Satellite pipe (C6W) and steeper slope angles implemented in the
Main pit Cut 4 East and Cut 4 West cutbacks. The cost savings associated with the recently concluded owner-mining initiative have been
included in the value-in-use model. Refer Note1.2.26, Critical accounting estimates and judgements.
Sensitivity to changes in assumptions
The Group will continue to test its assets for impairment where indications are identified.
Refer Note 1.2.26, Critical accounting estimates and judgements, for further details on impairment testing policies.
The short and medium-term diamond prices used in the impairment test have been set with reference to historical and recent prices
achieved, recent market trends and anticipated market supply and the Group’s medium-term forecast. Long-term diamond price
escalation reflects the Group’s assessment of market supply/demand fundamentals. The valuation of Letšeng at 31 December 2023
exceeded the carrying value by US$63.3 million (31 December 2022: US$92.2 million). The valuation is sensitive to input assumptions
particularly in relation to the foreign exchange assumption of the US dollar (US$) to the Lesotho loti (LSL) at year end, future price
growth for diamonds and increase in operating costs. The Group has assumed an appropriate price increase for its diamonds following
the significant pressure experienced in the diamond market during the year.
A range of alternative scenarios have been considered in determining whether there is a reasonable possible change in the foreign
exchange rates, operating costs and diamond prices, which would result in the recoverable amount equating to the carrying amount. A
7% strengthening of the LSL to the US$ to US$1:LSL17.00 (31 December 2022: 8% to US$1:LSL15.60) or a reduction of 5.0% (31
December 2022: 6.5%) to the starting diamond prices (at year end exchange rate) would result in the recoverable amount equating to
the current carrying value, with other valuation assumptions remaining the same. As a result of the variability in consumable prices such
as diesel and explosive costs, a third sensitivity on changes in costs was performed. An 8% (31 December 2022: 8%) increase in current
estimated operating costs of US$1.7 billion (31 December 2022: US$2.5 billion) over the life of mine would result in the recoverable
amount equating to the current carrying amount, with other valuation assumptions remaining the same.
As a result, no impairment charge was recognised for the Letšeng Diamonds CGU during the year.

This non-current asset relates to Letšeng’s Multi-aggregate Protection Insurance Policy with The Lesotho National Insurance Group (LNIGC) of M140.0 million (US$7.7
million) (31 December 2022: LSL140.0 million) entered into in October 2021. This policy has a remaining tenure of two-and-a-half years at year end (31 December 2022:
three-and-a-half-years). Premium payments of LSL30.0 million (US$1.6 million) (31 December 2022: LSL30.0 million (US$1.8 million)) for the policy are payable annually in
advance. Refer Note 23, Commitments and contingencies. The policy gives Letšeng the right to claim up to LSL75.0 million (31 December 2022: LSL75.0 million) for each-and-
every-loss and LSL150.0 million (31 December 2022: LSL150.0 million) in the aggregate (subject to terms and conditions contained in the policy). On expiry of the policy in
June 2026, all unutilised funds within the policy are due and payable to Letšeng. A non-current financial asset has been recognised for the unutilised premium paid to date,
net of underwriting service fee of LSL 2.1 million (US$0.1 million) (31 December 2022: LSL2.1 million (U$0.1 million)) as expensed as part of operating expenses within the
Statement of Profit or Loss. The non-current financial asset is measured at amortised cost in line with IFRS 9 Financial Instruments. Interest is earned on the unrealised
premium and recognised as finance income. The third premium payment of LSL 30.0 million (US$1.6 million) (31 December 2022: LSL30.0 million (US$1.8 million) was
financed through a 10-month loan through Premium Finance Partners (Proprietary) Limited. This non-current financial asset is ceded in favour of Premium Finance Partners
(Proprietary) Limited. Refer Note 16, Interest-bearing loans and borrowings.
2
Prepayments include insurance premiums prepaid at Letšeng of US$0.4 million (31 December 2022: US$0.4 million) which were also funded through Premium Finance
Partners (Proprietary) Limited. This prepayment is ceded in favour of Premium Finance Partners (Proprietary) Limited. Refer Note 16, Interest-bearing loans and borrowings.
Based on the nature of the Group’s customer base and the negligible exposure to credit risk through its customer base, insurance asset
and other financial assets, the expected credit loss is insignificant and has no impact on the Group.

Inventory is carried at the lower of cost or net realisable value.
There were no write-downs to net realisable value recorded in the current year. In the prior year, lower grade (highly diluted) ore
stockpile inventory at Letšeng was written down by US$1.5 million to net realisable value.
Part of the ore stockpile was historically treated by Alluvial Ventures, the third-party plant contractor. This contract expired during the
previous year and the plant was dismantled, resulting in the stockpiles being treated at a slower rate, causing the overall increase in the
balance. Refer Note 1.2.11, Inventories.

Treasury shares
During the previous year, the Board of Directors approved a share buyback programme to purchase up to US$2.0 million of the
Company’s ordinary shares. The sole purpose of the programme was to reduce the capital of the Company and the Company intends to
hold those ordinary shares purchased under the programme in treasury. Such treasury shares are not entitled to dividends and have no
voting rights. The share buyback programme was initiated on 12 April 2022. At 31 December 2022, 1 520 170 shares had been bought
back at the market value on the date of each buyback, equating to a weighted average price of 60.05 GB pence (78.07 US cents) per
share, totalling US$1.2 million (including transaction costs). This reduction in shares issued has been taken into account in calculating the
earnings per share. No further share buybacks have taken place since the prior year.

Gem Diamonds Limited provides security for both the Letšeng Diamonds and Gem Diamonds Limited RCF facilities over its bank
accounts domiciled in the United Kingdom (US$1.4 million) (31 December 2022: US$4.6 million) and over its 70% shareholding in
Letšeng Diamonds, refer Note 30. Material partly owned subsidiary.
The interest-bearing loans and borrowings subject to the US$ three-month LIBOR rate transitioned to a Secured Overnight Financing
Rate (SOFR) effective from 1 January 2023, in line with the IBOR phase 2 Amendments which became effective in 2021. The South
African JIBAR rates are yet to transition to alternative benchmark rates at the reporting period end. The interest-bearing loans and
borrowings that remain subject to the South African JIBAR rate include the LSL132.0 million unsecured project debt facility and the
ZAR300.0 million revolving credit facility.
The Group will continue to assess the impact of the interest rate benchmark reform on the Group's JIBAR interest-bearing loans and
borrowings as the revised benchmark rates are published or negotiated with the funders. The developments on these facilities from 1
January 2023 and their carrying amounts and maturities as at 31 December 2023 are disclosed in the note below.

Bank Limited (acting through its Rand Merchant Bank division) and Nedbank Limited (acting through its Nedbank Corporate and
Investment Banking division).
The facility is secured and expires on 22 December 2024, and has therefore been recorded as a current liability. The facility has a 24-

the facility.
The US$-based interest rate for this facility at 31 December 2023 was 10.65% (31 December 2022: 8.67%) which comprises term SOFR

Rehabilitation provisions
The provisions have been recognised as the Group has an obligation for rehabilitation of the mining areas. The provisions have been
calculated based on total estimated rehabilitation costs, discounted back to their present values over the estimated rehabilitation
period at the mining operations. The pre-tax discount rates are adjusted annually and reflect current market assessments.
In determining the amounts attributable to the rehabilitation provision at Letšeng, management used a discount rate of 11.4% (31
December 2022: 11.5%), estimated rehabilitation timing of 16 years (31 December 2022: 13 years) and an inflation rate of 7.2% (31
December 2022: 7.0%). Although the Letšeng rehabilitation quantum increased from the prior year mainly driven by the completion of
the PCA and annual reassessment of the estimated closure costs performed at the operation, the effect of the revised timing of the
rehabilitation, discount rate and interest rate used to present value the provision, together with a weakening exchange rate, had an
overall impact of reducing the provision.
At Ghaghoo, which continued its care and maintenance state, an independent rehabilitation assessment was performed during the year
based on the rehabilitation costs of certain areas of the mine which are expected to be rehabilitated. Following discussions with the
Ministry of Minerals and Energy and the Department of Mines of Botswana, it is anticipated that the mine site will be left in a state which
could enable a future operator to operate on the site, and therefore certain infrastructure, such as access roads to the mine, paving and
walkways, a new solar solution installation, borehole pump and water treatment plant, will remain intact and handed over to the
Government of Botswana through the Ministry of Minerals and Energy.
In determining the amounts attributable to the rehabilitation provision at Ghaghoo, management used a discount rate of 6.0% (31
December 2022: 6.0%), estimated rehabilitation timing of 5 years (31 December 2022: 5 years) and an inflation rate of 4.8% (31
December 2022: 4.8%). The decrease in the provision at Ghaghoo is mainly attributable to cost saving measures implemented by
management since the previous reporting date and the removal of certain camp site costs from the prior year cost estimate following
discussions with the Ministry of Minerals and Energy and the Department of Mines of Botswana as mentioned above.

Deferred tax assets were recognised on tax losses incurred by Letšeng during the current year as management believe Letšeng will generate future taxable income against
which the losses can be utilised.
The Group has not recognised a deferred tax liability for all taxable temporary differences associated with investments in subsidiaries
because it is able to control the timing of dividends and only part of the temporary difference is expected to reverse in the foreseeable
future. The gross temporary difference in respect of the undistributed reserves of the Group’s subsidiaries for which a deferred tax
liability has not been recognised is US$110.5 million (31 December 2022: US$134.3 million).
The deferred tax liability on unremitted earnings is based on the timing of expected dividends from the Group’s subsidiaries over the
next three years. There are no income tax consequences attached to the payment of dividends by Gem Diamonds Limited to its
shareholders.
The Group has estimated tax losses of US$208.5 million (of which US$155.7 million relates to Gem Diamonds Botswana) (31 December
2022: US$223.4 million, of which US$175.8 million related to Gem Diamonds Botswana) for which no deferred tax assets have been
recognised as management does not foresee any taxable profits or taxable temporary differences against which to utilise these. Letšeng
has no unrecognised deferred tax losses (31 December 2022: nil). The net decrease from the prior period is as a result of a total
estimated tax loss for which no deferred tax assets have been recognised of US$8.2 million, offset by tax assessment updates and forex
movements.
The majority of tax losses are generated in jurisdictions where tax losses do not expire, except for tax losses incurred by Gem Diamonds
Innovation Solutions CY Limited, within the Cyprus jurisdiction, which has unrecognised tax losses of US$2.0 million ((31 December 2022:
US$1.8 million) and if not utilised, will expire as indicated in the table below:

COMMITMENTS AND CONTINGENCIES
Commitments
Mining leases
Mining lease commitments represent the Group’s future obligation arising from agreements
entered into with local authorities in the mining areas that the Group operates.
The period of these commitments is determined as the lesser of the term of the agreement,
including renewable periods, or the LoM. The estimated lease obligation regarding the future
lease period, accepting stable inflation and exchange rates, is as follows:
– Within one year 218 187
– After one year but not more than five years 1 000 847
– More than five years 628 809
1 846 1 843
Equipment and service lease
Until 1 December 2023, the Group had entered into lease arrangements for the provision of
loading, hauling and other transportation services payable at a fixed rate per tonne of ore and
waste mined; power generator equipment payable based on a consumption basis; and rental
agreements for various mining equipment based on the fleet utilised. All lease payments relating
to this lease were variable in nature. A portion of the lease payment was expensed in the
consolidated statement of profit or loss and the portion relating to waste removal/stripping
costs was capitalised to the waste stripping asset in the proportions referred to under the
estimate and judgements applied to the Capitalised stripping costs (deferred waste). Refer Note
1.2.26, Critical accounting estimates and judgements.
This lease was early terminated, effective 1 December 2023 in terms of the transition to
insourced mining and therefore there are no commitments associated with this lease as at 31
December 2023. During the year, variable lease payments of US$31.6 million (31 December 2022:
US$39.5 million) relating to this lease, were paid. Refer Note 1.2.26, Critical accounting estimates
and judgements, and Note 17., Lease liabilities.
– Within one year – 32 645
– After one year but not more than five years – 32 514
– 65 159
Multi-aggregate protection policy
The Group, through its subsidiary Letšeng entered into a LSL140.0 million (US$7.7 million) Multi-
aggregate Protection Insurance Policy with the Lesotho National Insurance Group (LNIGC) in
October 2021. The policy has a tenure of 4 years and 9 months and consists of five premium
payments each payable annually in advance.
As at 31 December 2023 the Group has committed to settle the two remaining premium
payments, as well as the annual insurance risk finance service fee of 7% of the annual premium
and the surplus reserve finance cost fee of 1.5% on the cumulative net premiums surplus balance
carried over each year. These fees are either deductible from premium or payable upfront at the
option of Letšeng. The Group has elected to deduct the fees from the annual premiums,
therefore there is no additional cash commitment relating to these fees and the future cash flow
commitments are stated at the future premiums payable over the remaining insurance period.
Refer Note 12, Receivables and other assets for further detail on the policy.

Letšeng Diamonds Educational Fund

Kingdom of Lesotho, the Group has an obligation to provide funding for education and training
scholarships. The quantum of such funding is at the discretion of the Letšeng Diamonds
Education Fund Committee.

23. COMMITMENTS AND CONTINGENCIES (continued)
The main capital expenditure approved relates to the replacement of screens in Plant 1 and Plant 2 and the scrubber in Plant 1 at a
combined cost of US$1.5 million; and investment in continued residue storage extension of US$0.8 million. Other smaller capital
expenditure, all at Letšeng, relates to the continued construction of the bioremediation plant of US$0.3 million, the balance of the
investment in the new PCA of US$0.2 million and new investment in energy saving projects of US$0.3 million. The expenditure is
expected to be incurred over the next 12 months.
In the prior year, the main capital expenditure approved consisted mainly of the investment in the new PCA at Letšeng of US$2.6 million
and the Underground Feasibility Study of US$4.5 million. During the current year, the new PCA was successfully commissioned in
November 2023. Part of the Underground Feasibility Study was completed at a total cost of U$1.8 million.
Contingencies
The Group has conducted its operations in the ordinary course of business in accordance with its understanding and interpretation of
commercial arrangements and applicable legislation in the countries where the Group has operations. In certain specific transactions,
however, the relevant third party or authorities could have a different interpretation of those laws and regulations that could lead to
contingencies or additional liabilities for the Group. Having consulted professional advisers, the Group has identified possible disputes
approximating US$0.5 million (December 2022: US$0.3 million) relating mainly to labour matters.
The Group monitors possible tax claims within the various jurisdictions in which the Group operates. It is noted that tax legislation is
highly complex and subject to interpretation of the application of the law. It is common for tax authorities to review tax returns, and in
some instances, disputes may arise over the interpretation and application of the prevailing tax legislation. Due to the complexity of the
legislation, significant judgment is required to determine any effects of uncertainties in accounting for and disclosure of income taxes.
Uncertain tax positions that have been determined as being probable within the Group have been provided for and are disclosed to
such an extent that such disclosure does not prejudice the Group. Refer Note 1.2.26, Critical accounting estimates and judgements and
Note 6., Income tax expense. While it is difficult to predict the ultimate outcome in some cases, the Group does not anticipate that
there will be any material impact on the Group’s results, financial position or liquidity.

25. FINANCIAL RISK MANAGEMENT
Financial risk factors
The Group’s activities expose it to a variety of financial risks:
• market risk (including commodity price risk, foreign exchange risk and interest rate risk);
• credit risk; and
• liquidity risk.
The Group’s overall risk management programme focuses on the unpredictability of financial markets and seeks to minimise potential
adverse effects on the Group’s financial performance.
Risk management is carried out under policies approved by the Board of Directors. The Board provides principles for overall risk
management, as well as policies covering specific areas, such as foreign exchange risk, interest rate risk, credit risk, use of derivative
financial instruments and non-derivative financial instruments, and investing excess liquidity.
There have been no changes to the financial risk management policy since the prior year.
Capital management
For the purpose of the Group’s capital management, capital includes the issued share capital, share premium and liabilities on the
Group’s statement of financial position. The primary objective of the Group’s capital management is to ensure that it maintains a strong
credit rating and healthy capital ratios in order to support its business and maximise shareholder value. The Group manages its capital
structure and makes adjustments to it, in light of changes in economic conditions. To maintain or adjust the capital structure, the Group
may issue new shares, buy back its shares, or restructure its debt facilities. The management of the Group’s capital is performed by the
Board.
The Group’s capital management, among other things, aims to ensure that it meets financial covenants attached to its interest-bearing
loans and borrowings. Breaches in meeting the financial covenants would permit the bank to immediately call loans and borrowings.
There have been no breaches of the financial covenants in the current year.
At 31 December 2023, the Group had US$45.9 million (31 December 2022: US$82.6 million) of undrawn debt facilities and continues to
have the flexibility to manage the capital structure more efficiently by the use of these debt facilities, thus ensuring that an appropriate
gearing ratio is achieved.
Refer Note 16, Interest-bearing loans and borrowings for detail on the debt facilities within the Group.
a) Market risk
(i) Commodity price risk
The Group is subject to diamond price risk. Diamonds are not homogeneous products and the price of rough diamonds is not
monitored on a public index system. The fluctuation of prices is related to certain features of diamonds such as quality and size,
together with diamond market fundamentals. Diamond prices are marketed in US dollar and long-term US dollar per carat prices are
based on external market consensus forecasts. The Group does not have any financial instruments that may fluctuate as a result of
commodity price movements.
(ii) Foreign exchange rate risk
The Group operates internationally and is exposed to foreign exchange risk arising from various currency exposures, primarily with
respect to the Lesotho loti, South African rand and Botswana pula. Foreign exchange risk arises when future commercial transactions,
recognised assets and liabilities are denominated in a currency that is not the entity’s functional currency.
The Group’s sales are denominated in US dollar which is the functional currency of the Company, but not the functional currency of all
its operations.
The currency sensitivity analysis below is based on the following assumptions:
• Differences resulting from the translation of the financial statements of the subsidiaries into the Group’s presentation currency of US
dollar, are not taken into consideration;
• The major currency exposures for the Group relate to the US dollar and local currencies of subsidiaries. Foreign currency exposures
between two currencies where one is not the US dollar are deemed insignificant to the Group and have therefore been excluded
from the sensitivity analysis; and
• The analysis of the currency risk arises because of financial instruments which are denominated in a currency that is not the functional
currency of the relevant Group entity. The sensitivity has been based on financial assets and liabilities at 31 December 2023 and 31
December 2022.
There has been no change in the assumptions or method applied from the prior year.
Sensitivity analysis
At year-end, Letšeng had US$2.5 million (2022: US$40.4 thousand) cash on hand held in US$. If the US dollar had appreciated/
(depreciated) by 10% against the LSL, the Group’s profit before tax and equity at 31 December 2023 would have been US$0.3 million
higher/(lower) (31 December 2022: US$3.4 thousand).

25. FINANCIAL RISK MANAGEMENT (continued)
Capital management (continued)
a) Market risk (continued)
(iii) Forward exchange contracts
From time to time, the Group enters into forward exchange contracts to hedge the exposure to changes in foreign currency of future
sales of diamonds at Letšeng Diamonds. The Group performs no hedge accounting. At 31 December 2023, the Group had no forward
exchange contracts outstanding (31 December 2022: nil).
(iv) Interest rate risk
The Group’s income and operating cash flows are substantially independent of changes in market interest rates. The Group’s cash flow
interest rate risk arises from borrowings. Borrowings issued at variable rates expose the Group to cash flow interest rate risk. At the time
of taking new loans or borrowings, management uses its judgement to decide whether it believes that a fixed or variable rate borrowing
would be more favourable to the Group over the expected period until maturity.
Sensitivity analysis
If the interest rates on the interest-bearing loans and borrowings (increased)/decreased by 100 basis points (2022: 100 basis points)
during the year, profit before tax and equity would have been US$0.2 million (lower)/higher 31 December 2022: US$0.1 million).
(b) Credit risk
The Group’s potential concentration of credit risk consists mainly of cash deposits with banks, trade receivables, insurance asset and
other receivables. The Group’s short-term cash surpluses are placed with banks that have investment grade ratings, to minimise the
exposure to credit risk to the lowest level possible from the perspective of the Group’s cash and cash equivalents. The maximum credit
risk exposure relating to financial assets is represented by their carrying values as at the reporting dates.
The Group considers the credit standing of counterparties when making deposits to manage the credit risk.
Considering the nature of the Group’s ultimate customers and the relevant terms and conditions entered into with such customers, the
Group believes that credit risk is limited as the customers pay and settle their accounts on the date of receipt of goods.
The Group’s insurance premiums are placed with insurers and underwriters that have high-quality credit standings, to minimise the
exposure to credit risk to the lowest level possible from the perspective of the Group’s insurance asset.
No material other financial assets are impaired or past due and accordingly, no additional ECL or credit risk analysis has been provided.
The Group did not hold any form of collateral or credit enhancements for its credit exposures during the 31 December 2023 and 31
December 2022 financial reporting periods.
(c) Liquidity risk
Liquidity risk arises from the Group’s inability to obtain the funds it requires to comply with its commitments including the inability to
realise a financial asset in a short period of time at a price close to its fair value. Management manages the risk by maintaining sufficient
cash and marketable securities and ensuring access to financial institutions and shareholding funding. This ensures flexibility in
maintaining business operations and maximises opportunities. The Group has available undrawn debt facilities of US$45.9 million at
year end (2022: US$82.6 million). The Group’s facilities expire in December 2024. The current facility agreements have a two-year
renewal option subject to lender approval. Management will commence the process of renewal or extension in the second quarter of
2024.

The long-term incentive plans are described below:
Long-term incentive plan (LTIP)
Certain key employees are entitled to a grant of options, under the LTIP of the Company. The vesting of the options is dependent on
employees remaining in service for a prescribed period (normally three years) from the date of grant. Prior to the April 2022 award, the
fair value of share options granted was estimated at the date of the grant using an appropriate simulation model, taking into account
the terms and conditions upon which the options were granted. It took into account projected dividends and share price fluctuation co-
variances of the Company. Since 2022, the fair value of the share options granted have been based on the observable Gem Diamonds
Limited share price on the date of the award with no adjustments made to the price.
There is a nil exercise price for the options granted. The contractual life of the options is 10 years and there are no cash settlement
alternatives. The Company has no past practice of cash settlement.
The Company's LTIP policy is reviewed every 10 years.

LTIP 2007 Award
Under the 2007 LTIP rules, there is one award where options are still outstanding.
This award was awarded on the following basis:
To key employees (excluding Executive Directors):
• the award vests over a three-year period in tranches of a third of the award each year;
• the vesting of the award is dependent on service conditions and certain performance targets being met for the same three-year
period (classified as non-market conditions). These non-market condition awards are referred to as Nil Value options in the tables
below;
• if the performance or service conditions are not met, the options lapse;
• the performance conditions relating to the non-market conditions are not reflected in the fair value of the award at grant date;
• once the award vests, it is exercisable for seven years (ie contractual term is 10 years); and
• the vested award is equity settled.
To Executive Directors:
• the award vests over a three-year period;
• the vesting of the award is dependent on service conditions and both market and non-market performance conditions;
• 75% of the award granted is subject to non-market conditions (referred to as Nil Value options in tables below) and 25% to market
conditions (referred to as Market Value options in tables below) by reference to the Company’s total shareholder return (TSR) as
compared to a group of principal competitors;
• if the performance or service conditions are not met, the options lapse;
• the performance conditions relating to the non-market conditions are not reflected in the fair value of the award at grant date;
• once the award vests, it is exercisable for seven years (ie contractual term is 10 years); and
• the vested award is equity settled.
The fair value of the Nil value award is based on the observable Gem Diamonds Limited share price on the date of award with no
adjustments to the price made.
The following table reflects details of the award within the 2007 LTIP that remains outstanding:

LTIP 2017 Award
Under the 2017 LTIP rules, there are six awards where options are still outstanding.
All the awards were issued on the same basis as the 2007 LTIP.
LTIP 2017 Award – April 2023 award
On 21 April 2023, 250 860 nil-cost options were granted to certain key employees of the Company. In addition, 809 195 nil-cost options
were granted to certain Executive employees and the Executive Directors on a similar basis as the 2007 LTIP. These options were
granted in line with the introduction of the Gem Diamonds Incentive Plan (GDIP) in 2021, which integrates annual bonus awards with
awards under the LTIP. The options which vest in tranches of one-third per annum commencing on 21 April 2024, are exercisable
between the respective vesting dates and 21 April 2033. The fair value of the award is based on the observable Gem Diamonds Limited
share price on the date of the award with no adjustments to the price made.
This new award was made under predominantly the same basis as the 2007 LTIP, with the following differences:
To key employees (excluding Executive Directors):
• the number of awards granted are determined on the Group’s performance in the preceding financial year in terms of the Gem
Diamonds Incentive Plan (GDIP) introduced in 2021;
• the vesting of the award is dependent only on service conditions. There are no future performance conditions attached to the award;
• if the service conditions are not met, the options lapse;
• the fair value of the awards is based on the observable Gem Diamonds Limited share price on the date of award with no adjustments
to the price made; and
• the awards are subject to malus and clawback.
To Executive Directors as a bonus share award:
• the number of awards granted are determined on the Group’s performance in the preceding financial year in terms of the Gem
Diamonds Incentive Plan (GDIP) introduced in 2021;
• the vesting of the award is dependent only on service conditions. There are no future performance conditions attached to the award;
• if the service conditions are not met, the options lapse;
• the fair value of the awards is based on the observable Gem Diamonds Limited share price on the date of award with no adjustments
to the price made;
• the awards have a two-year holding period from the respective vesting dates and are exercisable for 10 years from the award date;
and
• the awards are subject to malus and clawback.
