COVID-19

One of the Group's priorities in 2021 was to safeguard its employees, contractors and surrounding communities from COVID-19 and, in doing so, it was able to operate uninterrupted throughout the year. Almost 100% of the Group's workforce has now been fully vaccinated against COVID-19.

TCFD and Climate

The Group adopted the recommendations of the Task Force on Climate-related Financial Disclosures during the year and concluded Phase 1 of its three-year TCFD roadmap. The Group took a measured and science-based approach to conclude its Group-wide climate change scenario analysis and to develop a climate change strategy, and will continue to do so while setting targets, metrics and setting its decarbonisation strategy.

Commenting on the results today, Clifford Elphick, Chief Executive Officer of Gem Diamonds, said:

"Gem Diamonds has delivered positive operational and financial results notwithstanding the continued challenges brought about by the COVID-19 pandemic on the availability of skills, equipment, spares and other aspects of the supply chain. One of our priorities remains the safety of our employees, contractors and surrounding communities and we are pleased that we were able to assist the Lesotho Government in its fight against COVID-19 with a donation of 20 000 vaccines and a new 4x4 ambulance capable of reaching remote communities. To date, nearly 100% of the Group's workforce has been vaccinated.

The Group has continued with its climate change journey and we're pleased with the progress made in 2021. Our science-based approach will stand us in good stead over the coming years in managing the physical and transition risks. We are also continuing to explore the opportunities that climate change might bring to our operations.

The continuing recovery of the diamond market in 2021 was evidenced by the robust prices achieved for Letšeng's large, high-value diamonds and there was also a significant improvement in the prices achieved for smaller diamonds. This resulted in positive cash flows and allowed Gem Diamonds to end the year in a strong financial position.

We are pleased to announce that based on the results achieved in 2021, the Board has proposed the payment of an ordinary dividend of 2.7 US cents per share."

The Company will host a live audio webcast presentation of the full year results today, 17 March 2022, at 9:30 GMT. This can be viewed on the Company's website: www.gemdiamonds.com

ABOUT GEM DIAMONDS:

Gem Diamonds is a leading global diamond producer of high value diamonds. The Company owns 70% of the Letšeng mine in Lesotho. The Letšeng mine is famous for the production of large, top colour, exceptional white diamonds, making it the highest dollar per carat kimberlite diamond mine in the world.

CHAIRPERSON'S STATEMENT

The Board took measures in 2021 to enhance risk management, improve stakeholder relations and meet the board independence requirements of the UK Governance Code.

Dear shareholders,

On behalf of your Board of Directors, I am pleased to share the Gem Diamonds Annual Report and Accounts for 2021, which describes both the Group's performance during the past year and the progress we have made against our longer-term strategic objectives.

2021 was certainly not without its challenges, with a combination of the impact of renewed COVID-19 waves and restrictions, planned periods of mining in lower grade areas of the resource and extreme weather conditions. Pleasingly, notwithstanding these challenges, operational stability improved significantly towards the end of the year. We also saw the positive effect of several important safety interventions (including a 24-hour 'Stop for Safety' campaign in June 2021) returning the operation to its usual strong level of safety performance following a number of disappointing safety incidents in the first half of the year. In parallel, robust global demand for our large high-value diamonds resulted in a solid financial performance of EBITDA of US$57.4 million, an increase of 8% on 2020, and revenue of US$201.9 million.

CONTINUOUSLY IMPROVING OUR GOVERNANCE APPROACH

As stewards of the interests of all stakeholders of the Group, the Directors strive to continuously improve governance and oversight. Good governance is the bedrock upon which the Group's reputation rests and it underpins operational efficiency, the relationships we have with employees, local communities and governments, and the respect we have for and in which we are held by our shareholders and the wider market. Ultimately, good governance is a crucial element in the sustainability of our business and the preservation of value for all stakeholders.

The Board's priorities in 2021:

   --      Ensuring safe and stable operations during the COVID-19 pandemic. 
   --      Enhancing risk management systems and processes. 
   --      Overseeing the adoption of the TCFD recommendations and Group climate change strategy. 
   --      Resolving certain shareholder concerns regarding the Board's independence. 
   --      Overseeing the renewal of the Group's funding arrangements. 
   --      Overseeing the pending sale of the Ghaghoo mine. 

"Good governance is a crucial element in the sustainability of our business and the preservation of value for all stakeholders"

- Harry Kenyon-Slaney -

During the past year, we worked hard to further refine our risk management systems and processes. This has enabled us to improve the identification, quantification and mitigation of operational and wider environmental and societal risks, and to assess their potential impact against the risk tolerance levels we judge appropriate for the Group. Practical examples include the restructuring of our insurance cover to mitigate the substantial recent increase in insurance cost and further refinement of our tailings management systems to align them fully with the ICMM's GISTM. Effective risk management and ongoing stakeholder engagement ensure that the Board is kept appraised of issues as they emerge and evolve, and that new opportunities are brought to the Board's attention.

As part of our governance process, we continually review our approaches to combatting systemic challenges. This year we have again reassessed and refreshed our positions on human rights, modern slavery, corruption and climate change. I am pleased that all employees and contractors have reaffirmed their commitment to these statements.

ADDRESSING SAFETY AND CLIMATE CHANGE

We regard the safety and health of our workforce as our highest priority and, while we are not complacent and can always do better, our track record over recent years has been solid. It was therefore a concern to the Board that our safety performance deteriorated during the first six months of 2021, but management took swift action to turn the situation around. The Letšeng mine was shut down for a full day in a 'Stop for Safety' campaign to allow the workforce to be addressed. A new safety culture programme was launched to reinforce the message that production must happen safely or not at all. Pleasingly the second half of the year showed a sharp recovery. The AIFR for the full year was 0.93.

Letšeng is located in a remote and pristine region of the world and the Board has always been sensitive to the need to operate in an environmentally responsible manner. In 2021, the existential threat of climate change moved to the centre of the public's consciousness and is top of mind for political and business leaders. As a mining company that is necessarily a sizeable consumer of energy, we have commenced the process of both understanding our contribution to greenhouse gas emissions and what we can do to limit it. Climate change is now a topic of discussion at every Board meeting and is a top priority in our risk management system.

Gem Diamonds has adopted six priority goals from the 17 UN SDGs and our ongoing inclusion in the FTSE4Good index is an external validation that our positive ESG practices align with global standards and expectations. There were no major or significant environmental incidents reported at any of our operations during the year.

VALUING DIVERSITY, SKILLS AND EXPERIENCE

While ours is a small Board, appropriate for the size of the Group, we are committed to aligning with the requirements of the UK Corporate Governance Code. In May, Johnny Velloza (previously deputy CEO) stepped down from the Board to ensure that the Board meets the independence requirements of the Code. We are grateful to Johnny for his significant contribution and commitment over the last five years and we continue to benefit from his technical expertise as a strategic adviser.

We welcomed Rosalind Kainyah MBE to the Board. Rosalind has decades of experience in corporate and environmental law, government relations, political risk management and sustainability. Her experience in diamond mining includes an Executive Director position at the De Beers Group and she adds valuable ESG and leadership skills to the Board.

The Nominations Committee oversees board and senior management succession planning, and this important work ensures that the Group's leadership is appropriately sized, regularly refreshed, diverse and equipped with the necessary skills. We believe that the Board, as currently constituted, contains the right balance of critical thinking capabilities, skills and experience and that the complementary perspectives included ensure appropriate independent oversight of the Group.

We are proud of our track record of local appointments and promotions with a representation of nearly 98% Lesotho nationals at Letšeng and steadily improving gender diversity throughout the Group.

LISTENING TO OUR STAKEHOLDERS

As the operator and 70% owner of the Letšeng mine, we regard ourselves as guests of the people of Lesotho. We endeavour to always maintain constructive, open and honest dialogue with local communities and government partners. We consider their priorities and ensure that they in turn understand the nature of our business and Letšeng's significant contribution to the national economy.

Since joining the Board in July 2019, Mazvi Maharasoa has been the designated non-Executive Director for workforce engagement. She engages directly with employee representatives and provides the Board with an unfiltered view on issues that people wish to raise. This engagement process has broadened our understanding of various concerns and has enhanced the channels via which employees can communicate with management and see their issues being resolved. The Board values this process as it gives us reassurance that employee voices are heard at the top of the organisation and has helped to strengthen our relationships with them. These interactions have been particularly important while access to the mine has been restricted during the COVID-19 pandemic.

ENTRENCHING AN ETHICAL CULTURE

Gem Diamonds has always maintained a strong set of ethical principles that remain the firm foundation of everything we do. We insist on transparency and have no tolerance for fraud, theft, modern slavery, child labour or any other wrongdoing. The culture espoused by the Board and senior management is one of transparency, openness, a willingness to challenge and to change, and these principles promote high standards of ethical behaviour throughout the Group. To support these principles we maintain a rigorous system of internal controls, a comprehensive internal audit programme and an anonymous whistleblowing facility.

SUSTAINABLE RETURNS FOR OUR SHAREHOLDERS

In line with our dividend policy to pay a dividend to shareholders when the financial strength of the Group allows, we are pleased to propose that a dividend of 2.7 US cents per share be declared for the 2021 financial year.

ACKNOWLEDGING OUR STAKEHOLDERS' CONTRIBUTIONS

Operating a large mine high in the Maluti Mountains of Lesotho under the constraints of COVID-19-related travel and access restrictions once again provided a considerable test for everyone at Gem Diamonds during 2021. Management's ability to oversee the operation remotely for extended periods is a testament first and foremost to the ability and fortitude of our workforce, to the quality of the systems and culture in place at the mine and the strength of our relationships with local community leaders and with the Government of the Kingdom of Lesotho.

On behalf of the Board, I therefore want to thank everyone who has contributed to the Group's success this past year despite considerable disruption to their lives and those of their families. We thank our employees, contractors, our community partners, the Government of the Kingdom of Lesotho and our shareholders for their ongoing support. Finally, I wish to thank my fellow Directors for the dedication and commitment they showed and the valuable contributions they made during the year.

BEING CONFIDENT ABOUT THE FUTURE

While there are some signs that the COVID-19 pandemic may be starting to wane, there remains a risk of further resurgences. The success of our efforts to largely shield our people over the past two years has given us confidence that we have the systems and processes in place to deal with this risk, to keep our people safe and maintain the supply chain that our operations depend on.

2021 marked the end of the four-year period over which we delivered in excess of the target of US$100 million by achieving US$110.0 million in revenue, productivity and cost savings generated through the Business Transformation programme launched in 2017. In 2022, our goal is to build on the success of this effort by further improvement of our operational consistency through the focused implementation of a rigorous continuous improvement culture. In addition, we vigorously continue to exploit opportunities to optimise the mine plan and to reduce our waste profile, investigate future options to explore underground mining at Letšeng and progress several technological innovations in our processing plants.

The climate change scenario analysis that the Group undertook in 2021 provides a strong foundation to incorporate climate change-related risks and opportunity considerations into future business plans, strategies and feasibility studies.

Diamond prices have recovered steadily since the second half of 2020 due to an improving market outlook and declining supply. Prices increased further in 2021 and it is pleasing to note that this trend has continued into 2022. While predicting the frequency of the recovery of large diamonds is impossible in the short term, consistent delivery of plant throughput volumes is the best way to yield results over time.

RISK MANAGEMENT

HOW WE APPROACH RISK

The Group's risk management framework, which is fully integrated within strategic and operational planning, aims to identify, manage and mitigate the risks and uncertainties to which the Group is exposed and combines top-down and bottom-up approaches with appropriate governance and oversight, as shown in the graphic below.

Risk management framework

The Board and its Committees oversee the most relevant and significant current and emerging risks facing the Group which include strategic, operational and external risks. These risks are actively monitored, managed and mitigated to the extent possible as their impact, individually or collectively, could affect the Group's ability to achieve its objectives.

While Gem Diamonds' risk management framework focuses on risk identification and mitigation, many factors that give rise to these risks also offer opportunities. The Group monitors existing and emerging opportunities and incorporates them into the strategy where they support the Group's vision.

The learnings from COVID-19 led to increased emphasis on identifying the possible implications of external macro risks and low-probability and high-consequence events to inform appropriate contingency plans. These risks are mitigated by building resilience and flexibility into our leadership and operational processes, and ensuring the Group is equipped to quickly quantify the size and scale of the emerging issue and adapt accordingly. Insurance cover plays an important role in risk mitigation, enabling the transfer of certain risk elements within the primary risk categories of the Group. While it does not eliminate the need for operational controls to manage and mitigate risk, it offsets the financial loss should the risk materialise.

Insurers have continued to decrease their exposure to the mining industry due to the risk perception created by the COVID-19 pandemic, as well as claims in the industry due to the looting experienced in South Africa in July 2021. As a result, the renewal of appropriate insurance has become challenging, leading to additional exclusions, reduced cover, increasing deductibles or excesses payable and increasing premiums. Reduced cover consequently directly impacts the Group's cash management risk. In response to these challenges, the Group has decided to adopt a new risk transfer strategy to address the substantial changes in the insurance market by developing a sustainable insurance solution for the Group in the medium to long term.

EMERGING RISKS

The Group risk framework includes an assessment of emerging risks which are indicators of future conditions from which new opportunities and threats can arise.

The Group's consideration of emerging risk includes those risks that:

   --     are likely to materialise or impact over a longer time frame than existing risks. 
   --     do not have much reference from prior experience. 

-- are likely to be assessed and monitored against vulnerability, velocity and preparedness when determining likelihood and impact.

The current emerging risks and opportunities being monitored by the Group are:

-- although the invasion of Russia into the Ukraine and consequential sanctions applied is a current event; the social, political and economic effect of this on commodity prices, supply chains and market conditions is unknown..

   --     lab-grown diamonds. 
   --     generational shifts in consumer preferences - social influencers. 
   --     the rate of advancement of digital technologies such as blockchain. 
   --     future workforce (automation, skills for the future, etc). 
   --     uncertainty around carbon tax. 

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 approval of the financial statements to be the most relevant period for consideration for this assessment, given the Group's current position and the potential impact of the principal risks documented on pages 37 to 44 on the Group's viability.

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 involves all relevant functions including operations, technology and innovation, 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 and environment in which the Group operates, even though the life of mine, the mining lease tenure and available estimated reserves exceed three years.

The business and strategic plan reflects the Directors' best estimate of the Group's prospects. The Directors 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.

REFINANCING OF GROUP FACILITIES

The refinancing of the Group's facilities which was completed in December 2021, significantly increased the Group's available facilities from US$67.6 million immediately before the refinancing to US$83.3 million thereafter, when fully unutilised. US$77.0 million of these facilities mature in December 2024, with the balance of US$6.3 million being a general banking facility with no set expiry date, but which is reviewed annually.

COVID-19

While there are promising signs that the impact of the COVID-19 pandemic may be dissipating, there remains a potential risk of further resurgences. The Group is confident in its ability to manage through any such resurgence given its experience and success to date, especially following the successful roll-out of vaccinations at Letšeng. The Group predominantly holds viewings for its rough tender sales in Antwerp, although viewings have been held in Tel Aviv and more recently in Dubai. Although international travel has been subject to changing levels of restrictions, the main diamond sales market in Antwerp has remained open. Diamond sales are concluded on Gem Diamonds' electronic tender platform which can be accessed from anywhere in the world. The Group is confident that it will be able to continue to hold tender viewings in Antwerp despite any potential COVID-19 travel restrictions.

CLIMATE CHANGE

The Board is cognisant of the risks presented by climate change and conscious of the need to minimise emissions. A Group-specific climate change scenario analysis has been conducted whereby the short- to medium- and longer-term physical and transitional 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, is 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 combustion-related fossil fuel use. 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 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 viability assessment and scenario stress testing. Management and the Board will continue to assess these impacts as the information becomes more certain.

STRESS TESTS

The scenarios tested considered the Group's revenue, EBITDA(1) , cash flows and other key financial ratios over the three-year period. The scenarios tested included the compounding effect of the factors below and were applied independently of each other.

CONCLUSION

The Group's current net cash(1) position of US$20.9 million as at 31 December 2021 and available facilities of US$74.3 million would enable it to withstand the impact of these scenarios over the three-year period. The revolving credit facilities which expire on 22 December 2024, has a 24-month extension period and the Group will follow all necessary processes to extend the facilities for this available period, as it has in the past. This position is supported by the cash-generating nature of the Group's core asset, Letšeng, and its flexibility in adjusting its operating plans within the normal course of business. Based on the robust assessment of the principal risks, prospects and viability of the Group, 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 2024.

(1) Net cash is calculated as cash and short-term deposits less drawn down bank facilities (excluding asset-based finance facility and insurance premium financing).

CHIEF EXECUTIVE'S REVIEW

We performed strongly in 2021 and operated in a safe and responsible manner to protect the wellbeing of our workforce.

Letšeng has a unique ore body with diamonds that are of the highest value of any kimberlite mine, and the most beautiful found anywhere in the world. Despite the many COVID-19-related challenges encountered during the year, the Group ended the year in a strong cash position (net cash of US$20.9 million) with the average price of Letšeng goods exceeding US$2 000 per carat in Q4. This robust pricing for Letšeng's large, high-quality diamonds has continued into 2022.

We aim to extract maximum value for our stakeholders by operating safely, responsibly and efficiently and exploring new technologies to reduce diamond damage during the diamond liberation process. Achieving the highest average prices of any kimberlite mine in the world requires an effective, transparent and competitive tender sales process which we boast in Antwerp and, more recently, in Dubai. In addition, the Group adheres to internationally recognised systems and processes which provide our clients and their customers the assurance that our diamonds are ethically mined.

EXTRACTING MAXIMUM VALUE FROM OUR OPERATIONS

The strategy during the second year of COVID-19 impact on our operations focused on driving the extraction of greater value from our assets.

The Group's Letšeng operation delivered a solid operating performance, despite the significant challenges presented by travel restrictions, supply chain constraints, extreme weather conditions and intermittent external power outages on site.

Tonnes treated increased 15% year on year as operations returned to normal after the COVID-19 shutdowns in 2020. Carats recovered increased 14% to 115 335 (2020: 100 780).

Six diamonds greater than 100 carats were recovered during the year, which is comparable to the 13-year average of eight, albeit lower than the 16 such diamonds recovered in 2020. Exceptional recoveries during the year included the two large high-quality Type IIa white diamonds of 367 and 245 carats which sold for US$26 160 per carat and US$40 139 per carat, respectively. Letšeng's operational performance is discussed in more detail on page 60.

The diamond market has recovered to levels not seen in some time and demand for the high-quality white diamonds produced at Letšeng is particularly strong. 21 diamonds sold for more than US$1 million each, generating revenue of US$64.5 million (2020: 34 diamonds contributing US$72.6 million). The average price achieved during the year decreased 4% to US$1 835 per carat (2020: US$1 908 per carat) from the sale of 109 697 carats (2020: 99 172). The decrease in the prices achieved compared to 2020 relates mainly to fewer large and exceptional diamond recoveries, and the overall quality of the diamonds recovered as a result of the areas of the resource mined during the year. The Group successfully hosted its first trial tender viewing in Dubai in September, making it easily accessible for important clients from the UAE, India and Israel to participate in the tender. The viewings were well-attended and contributed to the robust prices achieved. The Group will hold its next Dubai viewing in March 2022.

"We are committed to operating in an environmentally responsible way."

- Clifford Elphick -

Group revenue increased 6% to US$201.9 million (2020: US$189.6 million), which translates to underlying EBITDA(1) of US$57.4 million and earnings per share of 10.5 US cents. Operational cash generated amounted to US$71.3 million resulting in a net cash(2) position of US$20.9 million at the end of 2021. The Group-wide debt refinancing was successfully concluded during the year. An additional funder joined the lender group, bringing the total number of lenders to three. The Group's revolving credit facilities were increased from US$61.3 million to US$77.0 million, in dollar equivalent, and renewed for a three-year period.

Based on the positive financial performance of the Group in 2021, we are pleased to announce that the Board has proposed a dividend of 2.7 US cents per share. More information regarding the Group's financial results is included in the CFO review on page 52.

WORKING RESPONSIBLY AND MAINTAINING OUR SOCIAL LICENCE

Gem Diamonds aims to sustain a workplace safety culture founded on mutual care and collaboration across the workforce. We continue to roll out programmes to drive a behavioural, organisational and culture ethos of safe conduct in the workplace.

In the past year, there were no fatalities (2020: none), six LTIs (2020: 1), and we achieved an overall AIFR of 0.93.

We are committed to operating in an environmentally responsible way. Our tailings storage facility management process aligns with the ICMM's GISTM which ensures the responsible management and monitoring of the tailings storage and freshwater facilities with regular inspections by external experts.

We invest in our surrounding communities through our well- established CSI programme to improve educational outcomes, develop infrastructure and stimulate local enterprises to create self-sustaining employment independent of the mine. Implementing these programmes was a significant highlight in 2021 as we were able to successfully implement a number of 2020 projects delayed by the COVID-19 lockdowns, while also commencing with those projects planned for 2021. In addition, we were active in repairing roads, footbridges and other PAC infrastructure damaged by the extraordinary flooding in the Patiseng valley in the first quarter of the year.

We are particularly proud of the pipeline of in-country mining skills we have developed that will serve Letšeng, and Lesotho as a country, well into the future. We started operations with 250 people in 2006, more than half of whom were expatriates. There are now 1 591 people working at Letšeng, of whom 98% are Basotho. This is due to our significant investment in transferring of skills, sponsoring the studies of students in mining and business-related disciplines, and in coaching initiatives specific to our needs.

Responsible social and environmentally sourced diamonds are a consumer priority. We have adopted six of the UN SDGs and continue to support the GIA's use of blockchain technology to assure consumers of our diamonds' ethical footprint.

There were no major or significant stakeholder incidents reported during the year.

OPERATING THROUGH COVID-19

The challenge for our business over the last two years has been to keep our workforce safe, find ways to run efficiently and uninterrupted during COVID-19 and generate a return for our shareholders. We demonstrated our care and agility at the start of the pandemic by quickly establishing a testing laboratory, strict controls and protocols, giving confidence to employees, contractors, communities and the Government of the Kingdom of Lesotho that we were serious about keeping our people safe. The Group has incurred significant expenditure in implementing its COVID-19 protocols with the majority being spent at Letšeng, where an estimated LSL26.4 million (LSL17 375 per employee) was spent on COVID-19 management and prevention to date.

When vaccinations started in Lesotho in the second half of 2021, we acquired and donated 20 000 vaccines to the Lesotho Department of Health. As part of the national vaccination programme, we worked with the Department of Health to allow our workforce the opportunity to be vaccinated on site. We are proud to report that 99% of our workforce is fully vaccinated to date.

As a result of our early and proactive interventions, the mine operated continuously throughout 2021. However, travel restrictions made it challenging for Group management, contractors and certain technical skills to access the mine, and ongoing supply chain disruptions affected the timeous replenishment of essential spares and equipment. We remain alert to the effects of the pandemic on mental health and in response targeted wellness initiatives have been rolled out at the Johannesburg office and a full-time psychologist was appointed at Letšeng to support the workforce at the mine.

Focusing on climate change

We are cognisant of the risks presented by climate change and conscious of the need to minimise emissions and our environmental impact more broadly. Letšeng's physical location exposes the operation to extreme weather conditions including drought, strong wind, heavy rain, extreme cold and snow. The operation is well set up to manage these conditions and is experienced in sheltering and supporting our PACs when necessary.

We held climate change workshops and completed a Group-specific climate change scenario analysis to deepen our understanding of climate-related risks and its likely impacts on the Group. The TCFD framework is proving to be a useful tool to identify and assess climate change- related issues.

As users of grid and fossil fuel energy, our short-term focus is on improving energy efficiencies in our operating processes and reducing combustion-related fossil fuel use. We are assessing our options in the context of the size, nature and location of our operations, the required investment and the expectations of our main stakeholders.

The Group has appointed independent external subject matter experts to provide input into the climate change considerations that will inform governance, risk management and strategy decisions as well as climate change-related targets for the Group. Our approach to climate change is included on page 26.

PREPARING FOR THE FUTURE

The four-year BT target of US$100 million was exceeded by the end of the year with the achievement of US$110.0 million, and many of the embedded initiatives will continue to create value for the Group. We continue to foster a culture of continuous improvement to identify and execute value driving initiatives and look forward to realising the benefits thereof in the near future.

Our capital plans include funding for projects that will sustain growth and value creation. Advancing technologies to reduce diamond damage during processing is a focus and while the potential is clear, the slow pace of progress during the year was disappointing.

The current open pit mine plan for both Main and Satellite pipes extends to 2036. In preparing for the future, we are exploring the trade-off between the next cutback in Satellite pipe versus an earlier underground access to this ore body in a safe and efficient manner. To inform our decision in this regard, we deepened our knowledge of the resource body in 2021 through an extensive resource drilling programme and will continue this process into 2022.

OUTLOOK

The current strong diamond demand and the ongoing decrease in the number of diamond producers, suggests that the fundamentals are supportive for achieving higher diamond prices in the future. We will prioritise stable and consistent production while driving efficiencies and managing costs to maximise cash flows, sustain an appropriate capital return to shareholders and maintain our status as a responsible, safe and low-cost operation.

Russia's recent invasion of the Ukraine has created political turmoil and the impact on the global economy, and the diamond market in particular, is uncertain at this stage.

Our future success depends on ensuring access to the requisite technical expertise, which will require further investments in skills development and retention initiatives, as well as effective succession planning. We remain focused on safeguarding the health of employees and contractors against COVID-19 for as long as it persists. We will continue to support our PACs and assist the Government of the Kingdom of Lesotho in its efforts to manage the impact of the pandemic.

APPRECIATION

In closing, I thank the Board and our Chairperson for their leadership during the year. The management teams once again demonstrated their commitment to the Group, and I thank them for their exceptional efforts during another difficult year.

We thank our customers for their continued trust and patronage, and our shareholders for their support. I would like to acknowledge the Government of the Kingdom of Lesotho for allowing us to continue to operate in a safe and responsible manner through three COVID-19 waves during the year.

CHIEF FINANCIAL OFFICER'S REVIEW

Gem Diamonds generated positive cash flow and ended the year in a strong financial position, proposing a shareholder dividend for the second consecutive year.

-- Underlying EBITDA from continuing operations increased 8% to US$57.4 million from US$53.2 million in 2020

   --     Earnings per share from continuing operations: 13.2 US cents 
   --     Profit attributable to shareholders from continuing operations: US$18.5 million 
   --     Group's attributable profit: US$14.8 million 
   --     The Group ended the year in a net cash position of US$20.9 million (2020: US$34.6 million) 
   --     Unutilised available facilities of US$74.3 million 

"The successful refinancing of our facilities, which includes a sustainability-linked loan, further embeds our commitment to delivering the Group's ESG strategy."

- Michael Michael -

We generated another strong set of results and positive cash flows in 2021, against the backdrop of ongoing COVID-19 challenges. Our effective and early interventions in response to COVID-19 enabled operations to continuing uninterrupted throughout 2021, with an ongoing focus on protecting employees and contractors against infection whilst maximising production and continues to sell our diamonds at the highest obtainable market price.

Production throughput was constrained during the year with three waves of COVID-19 impacting the availability of equipment, spares, skills and supply chain management. This resulted in the Group resetting some of its full year production targets, although the strong performance in Q4 resulted in some of those metrics being exceeded. The diamond market showed significant recovery and we achieved US$1 835 per carat for the year.

We successfully concluded the Group-wide debt refinancing during the year by renewing our revolving credit facilities at an amount of US$77.0 million for a three-year period. US$32.3 million of this amount is a Sustainability Linked Loan (SLL) which links the margin and resultant interest rate on the loans to the Group's ESG performance, which is aligned to its sustainability strategy.

In further support of our commitment to sustainability and climate change-related matters, Phase 1 of our TCFD Adoption Strategy was concluded during the year by establishing the necessary foundations to support meaningful, science-based decision making. The TCFD-related workstreams completed during 2021 included:

   --        Establishing robust board and management governance structures; 

-- Strengthening the enterprise risk management processes to ensure the full ambit of climate risk are considered and managed;

   --        Concluding our climate change scenario analysis; and 

-- Identifying, assessing and plotting the impact of our physical and transition risks over the short-, medium- and long-term.

Underlying EBITDA(2) from continuing operations increased to US$57.4 million, from US$53.2 million in 2020. Profit attributable to shareholders from continuing operations for the year was US$18.5 million, equating to earnings per share from continuing operations of 13.2 US cents on a weighted average number of shares in issue of 140.3 million.

The Group ended the year with a cash balance of US$31.1 million and drawn down facilities of US$10.2 million, resulting in a net cash position of US$20.9 million (2020: net cash of US$34.6 million) and unutilised facilities of US$74.3 million.

Revenue

Rough diamond revenue of US$201.3 million was generated at Letšeng, achieving an average price of US$1 835 per carat (2020: US$1 908 per carat). The Group sold 21 diamonds for more than US$1.0 million each, contributing US$64.5 million to revenue.

The Group's increased revenue was mainly driven by higher volumes through normalised production (following the COVID-19-related disruptions in 2020) and improved market conditions. The overall dollar per carat achieved was negatively impacted by a decrease in large diamond recoveries during the year when compared to 2020.

Letšeng entered into partnership arrangements during the year that allows them to share in the margin uplift on the sale of the resultant polished diamonds. In 2021, additional revenue of US$0.3 million (2020: US$0.6 million) was generated from these partnership arrangements.

OPERATING EXPITURE

Group cost of sales increased by 8% to US$113.0 million from US$104.7 million in 2020. In 2021, the Group incurred US$0.7 million to manage and maintain protocols to contain the spread of COVID-19 at its operations (2020: US$1.0 million). In 2020, an additional US$2.9 million standing charges were incurred during the shutdown and ramp-up periods at Letšeng. Total waste-stripping costs amortised increased by 8% to US$46.8 million compared to US$43.4 million in 2020.

Total operating costs in local currency decreased by 4% to LSL1 677.4 million compared to LSL1 740.8 million in 2020 which includes the impact of non-cash accounting charges.

The unit cost per tonne treated decreased 15% to LSL271.75 (2020: LSL320.20 per tonne treated) due to more consistent operational throughputs and an increase in tonnes treated compared to 2020.

-- Direct cash costs (excluding waste) increased by 13% to LSL1 241.4 million in line with the increase of ore tonnes treated to 6.2 million, a 15% increase compared to 2020. Waste cash costs increased by 22% to LSL829.4 million which was also in line with the 20% increase in waste tonnes mined (18.7 million tonnes compared to 15.4 million tonnes in 2020). Direct cash costs per tonne treated of LSL185.59 which is similar to 2020. Waste cash cost per waste tonne mined increased marginally to LSL44.44 (2020: LSL43.70).

-- Third plant operator costs reflect payments to the contractor which are calculated from revenue generated by the sales from diamonds recovered through the contractor plant. In 2021, the total cash costs in local currency increased by 12% in line with the increase in carats recovered and sold.

-- Non-cash accounting charges: comprise waste amortisation, stockpile and diamond inventory movements and finance lease costs. The total impact of these charges in 2021 was LSL436.0 million compared to LSL645.6 million in 2020. The decrease is mainly driven by a build-up of ore stockpile to standard levels as mining activities normalised. An increase in diamond inventory on hand at year-end of about 3 500 carats driven by a higher grade mining mix post the last export of the year, also contributed to the decrease. Total waste amortisation charges decreased to LSL669.1 million (2020: LSL690.1 million), impacting the unit cost by LSL108.41 per tonne treated (2020: LSL131.56).

The diesel theft as discussed on page 115 had no material effect on operating costs or the unit cost per tonne treated.

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 stronger against the US dollar (compared to 2020), which increased the Group's US dollar-reported costs and decreased 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, Gem Diamonds pays royalties to the Government 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 increased by 11% to US$21.9 million (2020: US$19.8 million) in line with the increase in revenue.

CORPORATE EXPENSES

The technical and administrative offices 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.

Baseline corporate costs were US$8.2 million, a 4% increase compared to US$7.9 million in 2020. The benefits from the corporate cost initiatives implemented through BT continue to be realised. During the year, US$0.7 million in costs were incurred on ad hoc projects (2020: US$0.1 million), an increase of US$0.6 million compared to 2020, when all ad hoc projects were suspended due to COVID-19. Current year costs were impacted by the stronger South African Rand and British Pound against the US dollar.

Total expenditure for the year relating to the adoption of TCFD and CCSA amounted to US$0.2 million.

Underlying EBITDA(1) and attributable profit

Group underlying EBITDA(1) from continuing operations increased by 8% to US$57.4 million (2020: US$53.2 million) as a result of the increase in revenue. Profit attributable to shareholders was US$14.8 million, which translates to 10.5 US cents per share based on a weighted average number of shares in issue of 140.3 million.

CAPITAL EXPITURE

The Group's capital expenditure increased following the cash preservation focus in 2020. Letšeng's capital spend was incurred mainly on the completion of a single-occupancy accommodation block, the purchase and installation of an additional X-ray sorting machine, the replacement of an overland conveyor for one of the tailings storage facilities and expenditure on progressing the drilling work to develop our Resource and Reserve Statement. Total capital expenditure (excluding waste stripping) increased to US$4.0 million during the year (2020: US$1.6 million).

CASH AT HAND

Group cash generated from operating activities (before capital and waste investment of US$68.7 million) was US$71.3 million. At year end, cash on hand totalled US$31.1 million (2020: US$49.8 million), of which US$23.5 million is attributable to Gem Diamonds. All scheduled capital debt repayments during the year were made, totalling US$4.0 million. The overall result is a decrease in net cash of US$13.7 million year on year.

Letšeng declared and paid a dividend of LSL200.0 million (US$12.5 million) in 2021. Gem Diamonds paid a dividend to its shareholders of 2.5 US cents per share, totalling US$3.5 million after approval by the AGM in June 2021.

LOANS AND BORROWINGS

The Group-wide debt refinancing was successfully concluded on 23 December 2021. Letšeng's LSL500.0 million and Gem Diamonds' US$30.0 million revolving credit facilities (RCF), that were due to expire in December 2021, were refinanced for LSL750.0 million and US$30.0 million respectively, for an initial three-year period. The facilities were therefore increased from US$61.3 million to US$77.0 million, in dollar equivalent. Security for the facilities over Gem Diamonds' bank accounts and its shareholding in Letšeng was implemented after year-end.

The funding partners to the new facility agreement are Nedbank, Standard Bank and new to the Group, Firstrand Bank (through their respective operations). Nedbank's portion of the funding, totalling US$32.3 million, is a Sustainability-Linked Loan (SLL), which is 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.

The measurement dates for these KPIs are 31 December 2022 and 31 December 2023.

At year end, the Group had utilised facilities of US$10.2 million, resulting in a net cash position of US$20.9 million and available facilities of US$74.3 million, mainly comprising a net debt position of US$5.5 million (after US$9.0 million drawdown) at Gem Diamonds and a net cash position of US$24.2 million at Letšeng. Gem Diamonds ended the year with a US$9.0 million outstanding balance.

Letšeng made repayments of LSL56.9 million (US$3.8 million) on its project debt facility for the construction of the mining workshop complex. The outstanding balance of LSL19.0 million (US$1.2 million) will be repaid by September 2022.

The Group engages regularly with funders and credit providers to ensure continued access to funding and to manage cash flow requirements.

DISCONTINUED OPERATION

In line with the strategic objective to dispose of non-core assets, the Board and management remain committed to the sale of the Ghaghoo diamond mine in Botswana. Following the exclusivity agreement in the prior year, a binding share sale agreement was entered into for the sale of the mine in 2021. The agreement was subject to the fulfilment of certain suspensive conditions, including obtaining competition authority and regulatory approvals within Botswana. Prior to year end, the regulatory conditions were fulfilled and approvals were obtained from the Botswana Competition Authority. Although the transaction was not yet concluded by year end, management is pursuing to close it out as soon as possible.

The operation remains on care and maintenance and is classified as a discontinued operation and asset held for sale per IFRS 5 Non-current Assets Held for Sale and Discontinued Operations. Care and maintenance cash and non-cash costs amounted to US$3.7 million (2020: US$3.3 million) and have been recognised and disclosed separately in the Consolidated Statement of Profit or Loss. The increase in costs was mainly due to a non-cash impairment of redundant stock and spares during the year.

INSURANCE

Letšeng submitted a business interruption claim to its insurers for insured losses arising out of the 30-day COVID-19-related Government shutdown period in 2020 when the mine was required to be placed on care and maintenance. This claim has been rejected by the insurer and Letšeng has commenced the process to pursue it further.

Increased risk perception in the mining industry due to the COVID-19 pandemic and dam wall failures reported by other companies around the world have led to insurers decreasing their exposure to the industry. This has resulted in the renewal of appropriate insurance becoming challenging, leading to additional exclusions, reduced cover, increasing deductibles or excesses payable and increasing premiums. In response, the Group has implemented a new risk transfer strategy to address the substantial changes in the insurance market by developing a sustainable insurance solution for the Group in the medium to long term.

The Group assessed its potential maximum risk exposure and its history of insurance claims as a basis to transition its conventional approach to insurance cover to a more flexible model by retaining higher insurance excesses which resulted in an insurance premium saving. To mitigate the increased risk exposure of the higher deductibles in the unlikely event of an unexpected loss, the Group entered into a five-year Multi-aggregate Protection Insurance Policy.

SHARE-BASED PAYMENTS

The share-based payment charge for the year was US$0.4 million (2020: US$0.6 million). 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. No awards in line with the new GDIP or the existing Long-Term Incentive Plan (LTIP) were made in 2021.

Dividend

The Board is committed to sustaining shareholder value through the implementation of appropriate dividend policies and we aim to pay a dividend when the financial strength of the Group permits. The Board's proposed dividend in March 2021 of 2.5 US cents per share (US$3.5 million) was approved and paid to shareholders in June.

Based on the Group's financial performance during the year, the Board is proposing a dividend of 2.7 US cents per share (US$3.8 million). The dividend is subject to shareholder approval at the scheduled AGM on 8 June 2022.

TAXATION

The Group has applied all relevant principles in accordance with prevailing legislation in assessing its tax obligations. The Group's effective tax rate was 33.4%. 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 and permanent differences which are non-deductible for tax purposes.

As disclosed in the prior year, an amended tax assessment was issued to Letšeng by the Lesotho Revenue Authority (LRA) 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 LRA in March 2020, which was supported by the opinion of senior counsel. The LRA 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 and a court date is expected to be set in June 2022.

On 7 February 2022 Letšeng received an application from the LRA to amend its original grounds for the court application. Letšeng's counsel continues to review the LRA's proposed amendment of its case and has opposed the new application by the LRA. Senior counsel advice has been obtained for the new circumstances. This advice still reflects good prospects of success. There has therefore been no change in the judgement applied and the accounting treatment for this matter (refer Note 1.2.28, Critical accounting estimates and judgments for further detail).

SENSITIVITIES

A range of external factors outside of the Group's control have an impact on its ability to create financial value. The Group has the necessary resilience, balance sheet strength and access to funds to adjust for shifts in these factors. The graph below illustrates the sensitivity of 2021's EBITDA to various factors that have the most significant impact on our ability to create value.

PERFORMANCE

Safety

The Group's safety approach is founded on our commitment to zero harm and belief that all injuries are preventable. Letšeng recorded zero fatalities but six LTIs during 2021, resulting in an LTIFR of 0.24 (2020: 0.04) and an AIFR of 0.93 (2020: 0.76). An organisational safety culture initiative was implemented to advance the maturity of our operational safety practices and reduce the frequency of safety incidents experienced in H1, through focused interventions including a 24-hour 'Stop for Safety' campaign and critical control management.

The safety case study below, outlines the key 2021 safety interventions implemented to mature our safety culture at Letšeng and improve safety performance.

MATURING OUR ORGANISATIONAL SAFETY CULTURE

Our safety journey in 2021 reflects the Group's deep commitment to zero harm and the belief that all injuries are preventable.

During the first half of 2021, Letšeng recorded a series of safety incidents that led the leadership team taking to shut down operations for 24 hours for safety-focused engagements with the entire workforce.

The site-wide 'Stop for Safety' campaign was the first of its kind for the Group and Letšeng and was aimed at understanding the root causes of increased safety incidents, reaffirm the commitment to zero harm and to design a targeted strategy to address the identified root causes and other concerns raised by the workforce during the intensive engagements.

This campaign took place on 8 June. Group Executive Management and Letšeng's leadership teams, accompanied by our contractors' executive and operational management, engaged extensively with the workforce. An additional session for employees not on duty on the day was held the following week.

A comprehensive list of actions was put together to immediately address matters raised during these sessions, which spanned a range of topics, including:

   --        The continuing impacts of the COVID-19 pandemic. 
   --        Fatigue management. 
   --        Health and safety. 
   --        Human resource management and leadership. 

As part of the discussions, the workforce requested more regular employee engagement forums to discuss safety and other matters, and as such, monthly employee engagement sessions were established.

Following the 'Stop for Safety', we appointed external safety specialists to review our safety practices and identify opportunities for improvement. In support of this process, a safety perception survey was conducted in October to map the Group's current safety maturity level. The findings of the safety perception survey informed a safety-focused response plan to implement strategic programmes that aim to develop and mature safety practices and organisational culture at Letšeng.

The strategic safety programmes initiated in 2021 include:

   --        Critical control management. 
   --        Incident investigation and management. 
   --        Safety-focused leadership coaching. 
   --        Just Culture Model development. 

In addition to the above programmes, we are maturing from reacting to lagging indicators, which measure failures post- incident to leading indicators that measure performance and indicate whether safety and health controls are effective at managing safety risk, thus being more proactive in our safety strategy. This approach will be monitored and measured through a leading indicator safety committee that will meet monthly to conduct retrospective analysis of all the leading indicators to identify trends or potential red flags to allow a proactive response.

We recognise that with one operating mine, there is limited opportunity for cross-operational knowledge sharing and we have identified a need for external assistance to transfer knowledge, experience and expertise on safety-related matters. We have constituted a committee of experienced individuals, our 'Grey Hair Council', from a broad industry base with deep insight into industry leading safety practices. In 2021, this council provided valuable guidance and insights into actual safety incidents, which have been integrated into our safety response and management plans.

We remain committed to zero harm and continue to look for innovative ways to deepen our understanding of how we can keep ourselves and our teams safe.

The Group's Letšeng operation continued operating safely and responsibly throughout the year notwithstanding the ongoing impact of COVID-19 on the availability of spares and equipment, limited access to skills and services due to travel restrictions and supply chain disruptions, and lost shifts due to required quarantining. Fatigue and mental health challenges placed significant strain on the management and the workforce.

Waste tonnes mined increased 20% to 18.7 million tonnes from 15.6 million tonnes in 2020 (2020 being impacted by the 30-day COVID-19 shutdown).

The trial to further steepen the west side of the Satellite pipe was safely and successfully managed during the year, with blasting and berm retention controls well entrenched. A similar slope steepening programme is planned for the final cutbacks in the Main pit. This will significantly reduce waste volumes and related costs, and expose more ore over the life of the Main pipe open pit.

Ore mined in 2021 of 6.3 million tonnes (2020: 5.6 million tonnes) was in line with the requirements of the plants and stockpile management.

Although a successful year overall, the Letšeng operations experienced many challenges during the year, including:

-- intermittent Main pit closures due largely to extreme weather conditions and spillage caused by the split-shell mining method as one cutback is completed while the next starts.

   --        regional power grid instability and unplanned power cuts. 
   --        a breakdown of the primary jaw crusher at the end of the third quarter. 
   --        unscheduled and extended maintenance of critical plant equipment. 

Ore treated during 2021 of 6.2 million tonnes (2020: 5.4 million tonnes) comprised 5.2 million tonnes treated by Letšeng's plants (2020: 4.5 million) and 1.0 million tonnes treated by Alluvial Ventures, the third-party processing contractor (2020: 0.9 million).

Of the total ore treated, 2.7 million was sourced from the Main pipe, 3.3 million from the Satellite pipe with 0.2 million tonnes treated from the Main pipe stockpiles.

During the year we reduced the PCA throughput to ensure the longevity of our current PCA while the construction of the replacement PCA commences in 2022 and for commissioning in 2023. The new PCA comprises a twin module design with a combined throughput of c.1 000 tonnes/hour.

Total carats recovered in 2021 increased 14% to 115 335 carats (2020: 100 780 carats). Carats recovered increased by 1% when compared to 2019, which was a more comparable year not impacted by COVID-19. The BT initiative to re-treat historic and current recovery tailings through the mobile X-ray transmission sorting machine recovered 1 098 carats in 2021 (2020:1 341 carats). An additional 213 carats were recovered by the new fines X-ray sorting machine that was installed and commissioned in H2 with expected full production in H1 2022.

Overall grade for 2021 was 1.85cpht which is aligned with 2020 and in line with the expected reserve grade. The contribution from Satellite pipe material accounted for 54% of all material treated during the year (2020: 52%).

Revised Mine Plan

Following the change in design of the Satellite pit, resulting in the successful implementation of steeper slopes in 2019, and further steepening and pit design optimisation over the last three years, more ore has been exposed. This has resulted in the availability of ore from the Satellite pipe extending late into 2025, compared to the 2019 plan where it was depleted in mid- 2023. This has allowed the commencement of the waste stripping related to the next cutback (Cut 6 West / C6W) of the Satellite pit to be delayed to 2024.

In 2021, a preliminary conceptual study of an early-access underground in the Satellite pit was completed. An underground feasibility study will be commissioned in 2022 to assess the viability of an earlier shift to underground mining of the Satellite pipe and to evaluate the trade-off between this and C6W. The trade-off analysis between C6W and underground mining of the Satellite pit will be completed in 2023.

Our long-term mine plan has been revised accordingly to commence waste stripping related to C6W in 2024, previously 2022. At this rate of waste stripping, Satellite ore from C6W will be available from 2029. Pending the outcome of the proposed underground feasibility study, Satellite C6W cutback may be replaced by the early commencement of underground mining with the intention of bringing forward access to Satellite ore post the completion of Satellite Cut 5 West in 2025.

The waste mining profile for the next two years has therefore been reduced to an estimated 11.0 million and 11.6 million tonnes respectively. At this rate of waste stripping, Satellite ore from C6W will be available from 2029.

Large diamond recoveries

In 2021 Letšeng recovered six diamonds greater than 100 carats and total diamonds recovered greater than 10 carats increased by 4% year on year, mostly in the 10 to 20 carat size category. Although recoveries throughout the categories are mostly in line with the 13-year averages, the lower number of diamonds in the large categories (60 to 100 carats and greater than 100 carats) can be primarily attributed to the areas of the resource that were mined in 2021 versus what was mined in 2020. 2020 was a record year for these two categories of larger diamonds. A total of 122 greater than 100 carat diamonds have been recovered at Letšeng since 2006.

Mineral resources and reserves

A primary focus in 2021 was advancing the resource core drilling programme in the Main and Satellite pipes, using the new drill rig purchased at the end of 2020. As the new drilling crews and management systems were embedded, the number of shifts increased, and the drilling process accelerated. The main challenge facing demarcated drilling programme remains the competition with production activities for access to the drilling sites, which were all positioned in the pits. Although completion of the core drilling programme was a high priority, continued production activities remained paramount.

Resource drilling in the Satellite pipe progressed well and nine delineation drillholes were completed. The kimberlite contact of the Satellite pipe along the western wall deviated out slightly from the expected position at the current mining elevation and posed certain geotechnical risks. A series of 19 additional holes were drilled for geotechnical purposes at intervals along the length of the western wall to resolve the immediate risk to the mine design and pit wall stability. These drillholes detected an increase in the pipe margin, adding further ore to the resource base of Satellite pipe. Detailed petrography of the core is in progress and updated geological models are expected by mid-2022.

Resource drilling in the Main pipe proved more difficult, with ground conditions hampering drilling progress and resulting in several holes having to be abandoned and redrilled. Delays experienced related to excessive rainfall and the commencement of mining activities on the upper benches in the new cutback (Cut 4 East), creating unsafe working conditions for the drilling crews below and periodically restricting access to the drilling sites.

Two additional contractor drill rigs were brought to site to reduce the impact on the timeline for completion of the drilling programme and updating of the Resource and Reserve Statement. By year end, the objectives of the drilling programme in Satellite pipe had been met and only four of the 14 planned drillholes in Main pipe remained to be completed.

Diamond sales

Six rough diamond tender viewings were held in Antwerp and a first trial tender viewing was held in Dubai in September. Travel and other COVID-19-related restrictions had little impact on attendance at the tender viewings and demand remained strong throughout the year.

A total of 109 697 carats were sold in 2021 (2020: 99 172) and Letšeng generated rough diamond revenue of US$201.3 million (2020: US$189.2 million), at an average price of US$1 835 per carat (2020: US$1 908).

The Group supports the GIA's blockchain technology to inform and assure consumers about the ethical and socially supportive footprint of the diamonds being purchased. Blockchain technology can link the source of rough diamonds to the final polished diamonds, proving their authenticity, provenance and traceability, and supporting ethical sourcing and processing in the diamond value chain.

Capital projects

Although limited, capital was appropriately spent during 2021 in line with operational requirements. Certain capital was deferred into 2022 without putting the continuation of operations at risk. A number of key capital projects are planned for 2022, including the replacement of the PCA, the completion of the resource core drilling programme to inform Lesteng's Resource and Reserve Statement, the construction of the bioremediation plant, further evaluation of the underground development opportunities and expansion of the Patiseng coarse tailings storage facility. Details of overall costs and capital expenditure incurred at Letšeng during the year are included in the CFO review on pages 52 to 59.

Business Transformation

The Group's BT programme concluded at the end of 2021, exceeding the targeted US$100 million(1) in revenue, productivity and cost savings (against the 2017 base) by achieving a total of US$110.0 million, as set out below. The programme identified 325 initiatives to create a step change in efficiency, productivity and cost management, and to position Gem Diamonds favourably in its peer group.

(1) The target is stated net of implementation costs, consultant fees and an employee incentive plan that rewarded the successful delivery of initiatives contributing to the overall target.

The targeted US$100 million comprised US$7.1 million in once-off savings and US$103.0 million in cumulative recurring annualised benefits over four primary workstreams - mining, processing, working capital and overheads, and corporate activities. The implemented initiatives are sustainably embedded in the operation and continue to deliver benefits in reduced costs and improved efficiencies that have been critical in maximising operational cash flows, which was crucial in the Group's ability to successfully absorb the external shock of the COVID-19 pandemic.

Continuous Improvement

The CI programme aims to implement behavioural strategies and meaningful KPIs to create effective visual management tools and problem solving at all levels. The CI methodology, supported by training and coaching, enables the Group to continuously improve efficiencies by unlocking the inherent capabilities of employees at all levels to implement best practices, build effective teams and drive incremental improvements. Although severely hampered by COVID-19 restrictions and constraints, CI was successfully implemented in Mining at Letšeng in 2020, with the roll-out to the Treatment and Services areas commencing in 2021. In 2022, the programme will focus on training and focused coaching to improve skills and experience at the supervisory level.

A key strategic objective for the Group is to continuously identify opportunities to unlock value within our business. During 2021, we focused on continuous improvement opportunities to reduce mining-related costs and improve resource use efficiencies. At Letšeng, waste hauling distance is a major driver of both current and future mining costs and fossil fuel combustion-related greenhouse gas emissions.

We identified an opportunity to reduce both mining costs and greenhouse gas emissions through shorter mining waste haulage distances of our waste from the Main pit. Following extensive collaboration between our environmental and mining teams, a new mine waste dumping plan was designed and implemented. The revised plan has reduced the haulage distance of waste from the Main pit by 30%, resulting in a significant long- term reduction of the associated operational costs and diesel consumption, and advancing our sustainability objectives to lower carbon emissions.

By working together to design innovative solutions, we are able to unlock shared value and drive Group goals with regards to maximising value, managing costs and reducing our environmental footprint.

Dam safety and integrity

Letšeng has three dams on site - (i) the Patiseng tailings storage facility, which is currently in use for the deposition of coarse tailings and fine tailings, (ii) the Old Tailings Storage Facility, which is sporadically used for fine tailings deposition, and (iii) the Mothusi Dam, which is the mine's freshwater supply resource. Letšeng's dams were constructed using the 'centre line and downstream tipping' method(1) , which is a safer method of construction than the 'upstream' construction methods used in most recent dam failures reported in the mining industry.

We have aligned our tailings dam failures in the mining industry have shown the severe adverse impact these can have on human lives and the natural environment. Tailings dam integrity is consequently an ongoing area of significant focus for mining companies and investors.

The Group has aligned its tailings storage facility management code of practice to that of the ICMM's GISTM and established appropriate governance structures at both operational and Group levels to provide oversight and assurance of continued safe and responsible management of our tailings storage facilities. The relevant details of Letšeng's tailings storage facilities are available in our voluntary disclosure as part of the Investor Mining and Tailings Safety initiative set up by the Church of England, which can be found under the Company's name at http://tailing.grida.no/. Further information is available on page 78.

(1) A discussion of the construction and applicability of the various types of tailings facilities is available on the International Council of Mining and Metals website at www.icmm.com/en-gb/environment/tailings.

Preventing diamond damage

The large high-value Type II diamonds in Letšeng's orebody are more susceptible to damage through the mining and treatment processes. Diamond damage negatively impacts the value and in turn the sales prices realised for these diamonds. Reducing damage to these diamonds provides an important opportunity to significantly enhance revenue.

Our main focus in this regard has been on identifying, validating and testing technologies from various industries that show potential to identify diamonds within kimberlite at an early stage and liberate these using non-mechanical means. In 2019, the Group's wholly owned subsidiary, Gem Diamonds Innovation Solutions, constructed and commissioned a pilot plant at Letšeng to test this technology under operating conditions. Progress on the detection components of this pilot plant has been limited to the development of the detection and ejection algorithms and further development is required to enhance this technology. The materials handling component of the pilot plant now forms part of Letšeng's new fines XRT system that was commissioned in H2 of 2021.

Sale of Ghaghoo

A binding share sale agreement was entered into for the sale of the Ghaghoo diamond mine in Botswana to Okwa Diamonds Pty Ltd, an entity owned by Vast Resources PLC (Vast) and Botswana Diamonds PLC (BOD). The agreement is subject to the fulfilment of certain suspensive conditions including obtaining the competition authority and regulatory approvals within Botswana. Regulatory conditions have been fulfilled and written approvals have been obtained from the Botswana Competition Authority and, in December 2021, the Ministry of Mineral Resources, Green Technology and Energy Security of Botswana. However, the completion date for the transaction has been extended by two months to 31 March 2022 to allow BOD to secure an alternative financing partner to replace Vast.

OUR PLANS FOR 2022

A pre-evaluation of the feasibility of an earlier shift to underground operation will start early in 2022 and the replacement of the PCA will commence in the first half of the year. The contract with Alluvial Ventures, which runs the third processing plant, expired at the end of 2021 and has been extended to 30 June 2022. We are currently evaluating several options for a replacement 1.0 to 1.2 million tonne per annum XRT plant. Work continues to steepen slopes to optimise the mining plan for Main pipe and we will begin planning for the tailings extension at Patiseng. A number of other projects are planned to optimise mining efficiencies, improve production, decrease costs and reduce emissions in line with our commitment to decarbonisation.

     including the use of our valuation experts.

Other Information

Management is responsible for the other information. The other information comprises the information included in the 224-page document titled 'Gem Diamonds Annual Report and Accounts 2021'. The other information does not include the consolidated financial statements and our auditor's report thereon.

Our opinion on the consolidated financial statements does not cover the other information and we do not express 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 IFRSs, 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 judgment 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 identity 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.

            3 Gem Diamonds Botswana (Proprietary) Limited (Ghaghoo Diamond Mine), which is in the process 
            of being sold, has been classified as a discontinued operation held for sale since 30 June 
            2019 and disclosed separately (refer Note 15, Asset held for sale). 
 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, i.e. 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), classified as 
                 discontinued operation held for sale since 30 June 
                 2019. 
 
 
 
           Management monitors the operating results of the geographical units separately for the purpose 
           of making decisions about resource allocation and performance assessment. 
 
           Gem Diamonds Botswana (Proprietary) Limited (Ghaghoo Diamond Mine), which was classified as 
           a discontinued operation held for sale and disclosed separately from 2019, continues to be 
           classified as such at year end as management remain committed to the sales process. Refer 
           Note 15, Asset held for sale. 
 
           During the prior year Gem Equity Group, a dormant investment holding company registered in 
           the BVI, was abandoned. Following the sale of its investments within the prior year the Board 
           of Directors of Gem Equity Group resolved to voluntarily liquidate the company. The company 
           no longer exists as the liquidation was finalised on 2 July 2021 at a minimal liquidation 
           professional fee paid by Gem Diamonds Limited. There was no further impact on the Group's 
           results in the current year from the company. GEG was classified as part of the BVI, RSA, 
           UK and Cyprus segment. Calibrated Diamonds Investment Holdings (Proprietary) Limited (CDIH), 
           a 100% held subsidiary of Gem Diamonds Investments Limited was deregistered during the year 
           after being dormant for several years. There was no impact on the Group's results in the current 
           year from this company. CDIH was classified as part of the BVI, RSA, UK and Cyprus segment. 
 
           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.

 1.2      Summary of significant 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 1.2.16, 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 1.2.28, Critical accounting estimates and judgements. 
 
           Changes in accounting policies and disclosures 
 
           New and amended standards and interpretations 
           The Group applied for the first-time certain standards and amendments, which are effective 
           for annual periods beginning on or after 1 January 2021 (unless otherwise stated). The Group 
           has not early adopted any other standard, interpretation or amendment that has been issued 
           but is not yet effective. 
 
           The nature and effect of these changes as a result of the adoption of these new pronouncements 
           are described below. Other than the changes described below, the accounting policies adopted 
           are consistent with those of the previous financial year. 
 
           Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 - Interest rate benchmark reform 
           Phase 2 
           The amendment addresses issues that might affect financial reporting when an existing interest 
           rate benchmark is replaced with an alternative benchmark interest rate. In the prior year, 
           the Group and its funders commenced a comprehensive debt refinancing programme of the Group's 
           facilities. The refinancing programme incorporates the consideration of any risk posed to 
           the Group by phase two of the IBOR reform, which was effective from 1 January 2021. The IBOR 
           reform may potentially have an impact on the South African JIBAR, and LIBOR linked interest-bearing 
           loans and borrowings The interest-bearing loans and borrowings subject to the South African 
           JIBAR rate include the LSL215.0 million unsecured project debt facility between Letšeng 
           Diamonds, Nedbank Limited and the Export Credit Insurance Corporation (ECIC) and the ZAR300.0 
           million revolving credit facility between Letšeng Diamonds and Nedbank Limited. The interest-bearing 
           loans and borrowings subject to the US$ three-month LIBOR rate include the US$30.0 million 
           revolving credit facility between Gem Diamonds Limited, Nedbank Limited, Standard Bank of 
           South Africa Limited and Firstrand Bank Limited. Both the South African JIBAR and the LIBOR 
           rates are yet to transition to alternative benchmark rates at the reporting period end. Refer 
           to Note 17, Interest- bearing loans and borrowings for more information regarding the maturities 
           and the related benchmark rates subject to the IBOR reform on these loans and/or borrowing 
           facilities. At year end, it is not possible to estimate the potential impact of the amendment 
           as no alternative rates have been published by the regulatory bodies or negotiated with the 
           funders, however, in terms of the agreement, the LIBOR rate on the US$30.0 million revolving 
           credit facility of Gem Diamonds Limited will be replaced by 30 June 2022. The Group will continue 
           to assess the impact of the interest rate benchmark reform as the revised benchmark rates 
           are published or negotiated with the funders. This assessment will include considerations 
           on how the practical expedients available within the amendments will impact the Group's interest 
           rate benchmarking. 
 
           New standards issued but not yet effective 
           The new standards, amendments and improvements that are issued, but not yet effective, up 
           to the date of issuance of the Group's consolidated financial statements are listed in the 
           table below. These standards, amendments and improvements have not been early adopted and 
           it is expected that, where applicable, these standards, amendments and improvements will be 
           adopted on each respective effective date. The impact of the adoption of these standards cannot 
           be reasonably assessed at this stage.

           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. 
 1.2.2     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 26, 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 cash at 31 December 2021 was US$20.9 million (31 December 2020: net cash US$34.6 
            million). Following the successful refinancing of the Group's facilities for a three-year 
            period from 23 December 2021, the Group's undrawn facilities at 31 December 2021 amounted 
            to US$74.3 million, resulting in strong liquidity (defined as net cash and undrawn facilities) 
            of US$95.2 million (31 December 2020: US$95.4 million). The Group's Revolving Credit facilities, 
            which total US$77.0 million when fully unutilised, mature on 22 December 2024. The balance 
            of US$6.3 million is a general banking facility with no set expiry date , but is reviewed 
            annually (Refer Note 17, Interest-bearing loans and borrowings). The uncertainty that exists 
            around the ongoing impact of COVID-19 on future cashflows was considered by performing sensitivities 
            on diamond pricing and diamond production volumes and continued strengthening of the US$ against 
            the Lesotho Loti. 
 
            After making enquiries which include reviews of forecasts and budgets, timing of cash flows, 
            borrowing facilities and sensitivity analyses and considering the uncertainties described 
            in this report either directly or by cross-reference, the Directors have a reasonable expectation 
            that the Group has adequate financial resources to continue in operational existence for the 
            foreseeable future. For this reason, they 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 2021. 
 
            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 intragroup 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. 
 
 
 
            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 a component of 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 proved 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 are 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 and maintenance 
             are charged to the statement of profit or loss during the financial period in which they are 
             incurred. 
 
             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.

              1 Certain asset classes are depreciated over the lesser of life of mine, or period of mining 
              lease. Prior to 1 January 2020, the period of mining lease was shorter than the life of mine. 
              On 1 January 2020 a reassessment of assets' useful lives was performed at Letšeng which 
              resulted in a revision of assets' useful lives being made from a remaining useful life of 
              five years (original period of mining lease) to 15 years (life of mine) due to the extension 
              of the Letšeng mining lease. Furthermore, also within the prior year the useful life 
              of plant and equipment was reassessed from a useful life of 10 years to the remaining life 
              of mine (15 years); and the useful life of vehicles, categorised within the "Other assets 
              category", were reassessed from five years to eight years. 
            An item of property, plant and equipment and any significant part initially recognised is 
             derecognised upon disposal (i.e., 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 appropriate. 
 
             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 1.2.28, 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      Non-current assets held for sale and discontinued operations 
             The Group classifies non-current assets and disposal groups as held for sale if their carrying 
             amounts will be recovered principally through a sale transaction rather than through continuing 
             use. Such non-current assets and disposal groups classified as held for sale are measured 
             at the lower of their carrying amount and fair value less costs to sell. Costs to sell are 
             the incremental costs directly attributable to the sale, excluding the finance costs and income 
             tax expense. 
 
             The criteria for held-for-sale classification is regarded as met only when the sale is highly 
             probable, and the asset or disposal group is available for immediate sale in its present condition. 
             Actions required to complete the sale should indicate that it is unlikely that significant 
             changes to the sale will be made or that it will be withdrawn. Management must be committed 
             to the sale expected within one year from the date of the classification. 
 
             Property, plant and equipment and intangible assets are not depreciated or amortised once 
             classified as held for sale. 
 
             Assets and liabilities classified as held for sale are presented separately as current items 
             in the statement of financial position. 
 
             A disposal group qualifies as a discontinued operation if it is a component of an entity that 
             either has been disposed of, or is classified as held for sale, and: 
             (a) represents a separate major line of business or geographical area of operations; 
             (b) is part of a single co-ordinated plan to dispose of a separate major line of business 
             or geographical area of operations; or 
             (c) is a subsidiary acquired exclusively with a view to re-sale. 
 
             Discontinued operations are excluded from the results of continuing operations and are presented 
             as a single amount as profit or loss after tax from discontinued operations in the statement 
             of profit or loss. 
 
             Additional disclosures are provided in Note 15, Assets held for sale. All other notes to the 
             financial statements include amounts for continuing operations, unless indicated otherwise. 
 1.2.9      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. 
 1.2.10     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 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 time frame established by regulation or convention in the market place 
             (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 
             The Groups 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 1.2.7, Borrowing 
             costs, 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. 
 1.2.11     Fair value measurement 
             The Group's financial instruments or transactions that are classified to be measured at fair 
             value on a recurring basis are measured at fair value at each reporting date and financial 
             instruments and transactions that are measured at fair value on a non-recurring basis are 
             measured at fair value at the reporting date for which fair value measurement is relevant. 
 
             Fair value is the price that would be received to sell an asset or paid to transfer a liability 
             in an orderly transaction between market participants at the measurement date. The fair value 
             measurement is based on the presumption that the transaction to sell the asset or transfer 
             the liability takes place either: 
              *    in the principal market for the asset or liability; 
                   or 
 
 
              *    in the absence of a principal market, in the most 
                   advantageous market for the asset or liability. 
 
 
 
             The principal or the most advantageous market must be accessible by the Group. 
 
             The fair value of an asset or a liability is measured using the assumptions that market participants 
             would use when pricing the asset or liability, assuming that market participants act in their 
             economic best interest. 
 
             A fair value measurement of a non-financial asset takes into account a market participant's 
             ability to generate economic benefits by using the asset in its highest and best use or by 
             selling it to another market participant that would use the asset in its highest and best 
             use. 
 
             The Group uses valuation techniques that are appropriate in the circumstances and for which 
             sufficient data is available to measure fair value, maximising the use of relevant observable 
             inputs and minimising the use of unobservable inputs. All assets and liabilities for which 
             fair value is measured or disclosed in the financial statements are categorised within the 
             fair value hierarchy, described as follows, based on the lowest level input that is significant 
             to the fair value measurement as a whole: 
             Level 1: Quoted (unadjusted) market prices in active markets for identical assets or liabilities. 
             Level 2: Valuation techniques for which the lowest level input that is significant to the 
             fair value measurement is directly or indirectly observable. 
             Level 3: Valuation techniques for which the lowest level input that is significant to the 
             fair value measurement is unobservable. 
 
             For assets and liabilities that are recognised in the financial statements that are measured 
             at fair value on a recurring and non- recurring basis, the Group determines whether transfers 
             have occurred between levels in the fair value hierarchy by reassessing categorisation (based 
             on the lowest level input that is significant to the fair value measurement as a whole) at 
             the end of each reporting period. 
 1.2.12     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. 
 
             Financial assets 
             Financial assets carried at amortised cost 
             The Group recognises an allowance for expected credit losses (ECLs) for all financial assets 
             at amortised costs in the statement of profit or loss. ECLs are based on the difference between 
             the contractual cash flows due in accordance with the contract and all the cash flows that 
             the Group expects to receive, discounted at an approximation of the original effective interest 
             rate. The expected cash flows will include cash flows from the sale of collateral held or 
             other credit enhancements that are integral to the contractual terms. 
 
             For credit exposures for which there has not been a significant increase in credit risk since 
             initial recognition, ECLs are provided for credit losses that result from default events that 
             are possible within the next 12-months (a 12-month ECL). For those credit exposures for which 
             there has been a significant increase in credit risk since initial recognition, a loss allowance 
             is required for credit losses expected over the remaining life of the exposure, irrespective 
             of the timing of the default (a lifetime ECL). 
 1.2.13     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. 
 1.2.14     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. 
 
             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. 
 1.2.15     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. 
 1.2.16     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 16, Issued 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. 
 1.2.17     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). In situations where some or all of the goods or services received 
             by the entity as consideration for equity instruments cannot be specifically identified, they 
             are measured as the difference between the fair value of the share-based payment and the fair 
             value of any identifiable goods or services received at the grant date. 
 
             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. 
 
             Where the terms of an equity-settled award are modified, or a new award is designated as replacing 
             a cancelled or settled award, the cost based on the original award terms continues to be recognised 
             over the original vesting period. In addition, an expense is recognised over the remainder 
             of the new vesting period for the incremental fair value of any modification, based on the 
             difference between the fair value of the original award and the fair value of the modified 
             award, both as measured on the date of the modification. No reduction is recognised if this 
             difference is negative, due to the fact that it would not be beneficial to the employees. 
 
             Where an equity-settled award is cancelled, it is treated as if it had vested on the date 
             of cancellation, and any cost not yet recognised in the statement of profit or loss for the 
             award is expensed immediately. Where an equity-settled award is forfeited, it is treated as 
             if vesting conditions had not been met and all costs previously recognised are reversed and 
             recognised in income immediately within the year of forfeiture. 
 
             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 Note 1.2.28, Critical accounting estimates and judgements. 
 
             The Group periodically releases the share-based equity reserve to retained earnings in relation 
             to lapsed, forfeited and exercised options. 
 1.2.18     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. 
 1.2.19     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 1.2.28, Critical 
             accounting estimates and judgements. 
 1.2.20     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. 
 1.2.21     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. 
 1.2.22     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 1.2.12, 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. 
 1.2.23     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 joint operation arrangements is recognised for the sale of the rough diamond 
            according to each party's percentage entitlement as per the joint operation arrangement. Contractual 
            agreements are entered into between the Group and the joint operation partner whereby both 
            parties control jointly the cutting and polishing activities relating to the diamond. All 
            decisions pertaining to the cutting and polishing of the diamonds require unanimous consent 
            from both parties. Once these activities are complete, the polished diamond is sold, after 
            which the revenue on the remaining percentage of the rough diamond is recognised, together 
            with additional uplift on the joint operation arrangement. The Group portion of inventories 
            related to these transactions is included in the total inventories balance. 
 
            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 service 
            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. 
 
            Contract assets 
            A contract asset is the right to consideration in exchange for goods or services transferred 
            to the customer. If the Group transfers goods or services to a customer before the customer 
            pays consideration or before payment is due, a contract asset is recognised for the earned 
            consideration that is conditional. The Group does not have any contract assets as performance 
            and a right to consideration occurs within a short period of time and all rights to consideration 
            are unconditional. 
 
            Contract liabilities 
            A contract liability is the obligation to transfer goods or services to a customer for which 
            the Group has received consideration (or an amount of consideration is due) from the customer. 
            If a customer pays consideration before the Group transfers goods or services to the customer, 
            a contract liability is recognised when the payment is made or the payment is due (whichever 
            is earlier). Contract liabilities are recognised as revenue when the Group performs under 
            the contract. The Group does not have any contract liabilities as the transfer of goods or 
            services occurs within a short period of time of receiving the consideration. 
 1.2.24     Interest income 
             Interest income is recognised on a time proportion basis using the effective interest rate 
             method. 
 1.2.25     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. 
 1.2.26     Finance costs 
             Finance costs are recognised on a time proportion basis using the effective interest rate 
             method. 
 1.2.27     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. 
 1.2.28     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. 
 
             COVID-19 
             The Group has considered the impact of COVID-19 on its significant accounting judgements and 
             estimates. The Group's main source of estimation uncertainty is in relation to assumptions 
             used for the assessment of impairment and impairment reversal of assets. No further significant 
             estimates have been identified as a result of COVID-19, although the pandemic has increased 
             the level of uncertainty inherent in all future cash flow forecasts. 
 
             Task Force on Climate-related Financial Disclosures (TCFD) 
             In preparing the Consolidated Financial Statements management has considered the impact of 
             climate change, particularly in the context of the disclosures included in the Strategic Report 
             this year detailing the phased approach strategy which the Group has adopted in implementing 
             the 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 2023 nor viability over the next three 
             years. These considerations also had no material impact on any Property, Plant and Equipment 
             or Commitments. For Letšeng, the physical risks identified of extreme weather conditions, 
             are similar to its current operating conditions of drought, high wind, extreme precipitation 
             and cold events. 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 to reducing combustion related 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. 
 
             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 21, 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 21, 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, 
             exchange rates, 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. The results of the impairment 
             testing performed did not indicate any impairments in the current year. 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 2037 (2020: 2034). 
 
             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 
             and processing costs in the short to medium term have been based on the agreements with the 
             relevant contractors. In the longer term, management has applied local inflation rates of 
             5.0% (2020: 4.0% to 5.3%) for operating costs in addition to a depth escalation factor for 
             mining costs as a result of mining in deeper areas within both pits. 
 
             Capital costs in the short-term has been based on management's capital program after which 
             a fixed percentage of operating costs have been applied to determine the capital costs necessary 
             to maintain current levels of operations. 
 
             Exchange rates 
             Exchange rates are estimated based on an assessment at current market fundamentals and long-term 
             expectations. The US dollar/Lesotho loti (LSL) exchange rate used was determined with reference 
             to the closing rate at 31 December 2021 of LSL15.96 (31 December 2020: LSL14.69). 
 
             Diamond prices 
             The medium-term diamond prices used in the impairment test have been set with reference to 
             recent prices achieved, recent market trends 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 11.5% for revenue (2020: 10.8%) and 13.4% for costs (2020: 14.3%) 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; 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. 
 
 
 
             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. 
 
             Capitalised stripping costs (deferred waste) 
             Waste removal costs (stripping costs) are incurred during the development and production phases 
             at surface mining operations. Furthermore, during the production phase, stripping costs are 
             incurred in i) the production of inventory and ii) in the creation of future benefits by improving 
             access and mining flexibility in respect of the ore to be mined, (the 'stripping activity 
             asset'). Judgement is required to distinguish between these two activities at Letšeng. 
             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. 
 
             Judgement is also required to identify a suitable production measure that can be applied in 
             the calculation and allocation of production stripping costs between inventory and the stripping 
             activity asset. The ratio of expected volume (tonnes) of waste to be stripped for an expected 
             volume (tonnes) of ore to be mined for a specific component of the orebody, compared to the 
             current period ratio of actual volume (tonnes) of waste stripped to the volume (tonnes) of 
             ore mined is considered to determine the most suitable production measure. 
 
             These judgements and estimates are used to calculate and allocate the production stripping 
             costs to inventory and/or the stripping activity asset(s). Furthermore, judgements and estimates 
             are also used to apply the stripping ratio calculation in determining the amortisation of 
             the stripping activity asset. Refer Note 8, Property, plant and equipment and Note 13, Inventories. 
 
             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 27, Share-based payments, for further 
             detail. 
 
             Identifying uncertainties over tax treatments 
             As disclosed in the prior year, an amended tax assessment was issued to Letšeng by the 
             Lesotho Revenue Authority (LRA) 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 LRA in March 2020, which was supported by the opinion of senior 
             counsel. The LRA 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 and a court date is expected to be set in June 2022. 
 
             On 7 February 2022, Letšeng received an application from the LRA to amend its original 
             grounds for the court application. Letšeng's counsel continues to review the LRA's proposed 
             amendment and has opposed the new application by the LRA. 
 
             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, 
             is required to be raised in the 2021 Annual Financial Statements. 
 
             Equipment and service lease 
             The major components of Letšeng's ore-extraction mining activities are outsourced to 
             a mining contractor. The mining contractor performs these functions using their own equipment. 
             Management applied judgement when evaluating whether the contract between Letšeng and 
             the mining contractor contained a lease. While it was concluded there was a lease, lease payments 
             are variable in nature as the lease payment vary based on the tonnes of ore and waste mined 
             and hence no right of use asset or liability could be measured. A portion of the lease payment 
             is expensed in the consolidated statement of profit or loss and the portion relating to waste 
             removal/stripping costs is 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 24, Commitments and contingencies.

  The revenue from the sale of goods mainly 
   represents the sale of rough diamonds, for which 
   revenue is recognised at the point in time at 
   which control transfers. 
 
   The revenue from partnership arrangements of 
   US$0.2 million represents the additional uplift 
   from partnership arrangements for which revenue is 
   recognised when the significant constraints 
   are lifted or resolved and the amount of revenue 
   is guaranteed (2020: US$0.6 million). At 
   year end 894 carats (2020: 485 carats) have 
   significant constraints in recognising revenue 
   relating to the additional uplift. 
 
   The revenue from the rendering of services mainly 
   represents the sales of rough diamonds on 
   behalf of third parties, for which revenue is 
   recognised at the time when performance 
   obligations 
   are met, and services rendered on third-party 
   diamond analysis and manufacturing, for which 
   the revenue is recognised over time as the 
   services are rendered. 
 
   No revenue was generated from joint operation 
   arrangements during the current or prior year 
   (2021: Nil) (2020: Nil).

  COVID-19 standing costs 
   During the prior year, COVID-19 standing costs consisted of US$2.9 million which related to 
   certain standing fixed mining contract and ore stockpile movement costs which were incurred 
   during the brief period that the mine suspended operations in compliance with the Lesotho 
   lockdown order and was placed on care and maintenance, and were recognised as abnormal costs 
   and expensed immediately in the Consolidated Statement of Profit or Loss. The remaining 
   US$1.0 
   million related to costs incurred to implement protocols throughout the Group to address the 
   risk and curb the spread of COVID-19. In the current year, there were no abnormal standing 
   costs incurred. Costs of US$0.7 million were incurred relating to continued protocols for 
   curbing the spread of the virus.                                                                   (591)    (3 911)

          1 Other assets comprise motor vehicles, computer equipment, furniture and fittings, and office 
          equipment. 
          2 Certain assets at Letšeng that were no longer in use were scrapped. 
          3 The 2020 reassessment of assets' useful lives undertaken at Letšeng resulted in certain 
          assets' useful lives being realigned from the period of mining lease to the life of mine. 
          This resulted in a reduction in depreciation charge which will continue into the future. Refer 
          Note 1.2.6, Property, plant and equipment.

         At year end, plant and equipment mainly comprise printing equipment utilised at Gem Diamond 
          Technical Services. Motor vehicles mainly comprise vehicles utilised by contractors at Letšeng. 
          Buildings comprise office buildings in Maseru, Antwerp, London 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, the lease contract for back-up power generating equipment and the lease for 
          certain vehicles used on the mine at Letšeng came to an end. The assets and liabilities 
          associated with these leases have been derecognised. A new lease for back-up power generating 
          equipment is in the process of being negotiated. In the interim, Letšeng is renting existing 
          back-up power generating equipment on a month-to-month basis. Furthermore, Gem Diamonds Limited 
          and Gem Diamonds Technical Services entered into new contracts for the rental of office space 
          in London and Johannesburg respectively. The new contracts were assessed as containing leases, 
          which resulted in the recognition of the new associated right-of-use assets and lease liabilities. 
          The original contracts were both cancelled and all associated assets and liabilities were 
          derecognised. 
 
          In the prior year, Letšeng entered into a new contract with its existing ore processing 
          contractor. The new contract was assessed as not containing a lease as Letšeng no longer 
          retained the right to control the use of the assets associated with the contract. The original 
          contract, which was assessed as containing a lease on adoption on 1 January 2019, was cancelled 
          and all associated assets and liabilities were derecognised. Furthermore, in the prior year, 
          Gem Diamonds Limited entered into a new contract for the rental of its office space in London. 
          The new contract was assessed as containing a lease resulting in the recognition of the associated 
          assets and liabilities. The original contract was cancelled, and the associated assets and 
          liabilities were derecognised. 
 
          Total gains of US$0.1 million (2020: US$0.2 million) relating to the derecognition of leases 
          in the Group have been recognised in the Consolidated Statement of Profit or Loss. Refer Note 
          18, Lease Liabilities and Note 23.1, Cash generated by operations. During the year the Group 
          recognised income of US$0.3 million (2020: 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 the following years:

 11.    IMPAIRMENT TESTING 
        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 2021. 
        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 
        2021, 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 
   Cash flows are projected for a period up to the date that the open pit mining is expected 
   to cease in 2037 (in terms of IAS 36). This is based on the latest available mine plan and 
   is shorter than the mining lease period which extends to 2029 with an exclusive option to 
   renew for a further 10 years to 2039. This mine plan takes into account the available reserves 
   and other relevant inputs such as diamond pricing, costs and geotechnical parameters. 
 
   Sensitivity to changes in assumptions 
   The Group will continue to test its assets for impairment where indications are identified. 
 
   Refer Note 1.2.28, 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 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 2021 exceeded 
   the carrying value at an attributable level by US$35.1 million (31 December 2020: US$83.0 
   million). The valuation is sensitive to input assumptions particularly in relation to the 
   foreign exchange assumption of the US dollar (US$) to the Lesotho loti (LSL) and the future 
   price growth for diamonds. The Group has assumed an appropriate price increase for its diamonds 
   following the market improvement noted in the diamond prices during the year. 
 
   A range of alternative scenarios have been considered in determining whether there is a reasonably 
   possible change in the foreign exchange rates in conjunction with a reasonably possible change 
   in the diamond price recovery, which would result in the recoverable amount equating to the 
   carrying amount. A 5% strengthening of the LSL to the US$ to US$1:LSL15.15 or a further reduction 
   of 4% to the starting diamond prices would result in the recoverable amount equating to the 
   current carrying value (at year end exchange rate), with other valuation assumptions remaining 
   the same. 
 
   As a result, no impairment charge was recognised during the year.

    1 During the year, the Group, through its subsidiary Letšeng, transitioned its conventional 
    approach to insurance cover towards a more flexible approach, through retaining higher insurance 
    excesses, thereby obtaining an insurance premium saving and ultimately preserving cashflow. 
    To mitigate the increased risk exposure of the higher deductible in the unlikely event of 
    an unexpected loss, Letšeng entered into a LSL100.0 million (US$6.2 million) Multi-aggregate 
    Protection Insurance Policy with The Lesotho National Insurance Group (LNIGC) on 1 October 
    2021. This policy has a tenure of 4 years and 9 months, consisting of five premium payments 
    of LSL20.0 million (US$1.3 million), each payable annually in advance (refer Note 24, Commitments 
    and contingencies). This policy gives Letšeng the right to claim up to LSL50.0 million 
    for each-and-every- loss and LSL100.0 million in the aggregate (subject to terms and conditions 
    contained in the policy), from inception of 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 
    and fronting fees as expensed within other operating expenses. The non-current financial asset 
    is measured at amortised cost in line with IFRS 9. Interest is earned on the unrealised premium 
    and recognised as finance income. The first premium payment 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 17, Interest 
    Bearing Loans and Borrowings. 
    2 Prepayments include insurance premiums prepaid at Letšeng Diamonds of US$0.3 million 
    (31 December 2020: US$0.6 million) and Gem Diamonds Technical Services of US$0.2 million (31 
    December 2020: US$0.1 million) which were funded through Premium Finance Partners (Proprietary) 
    Limited. This prepayment is ceded in favour of Premium Finance Partners (Proprietary) Limited. 
    Refer Note 17, Interest Bearing Loans and Borrowings. 
 
    Based on the nature of the Group's client base and the negligible exposure to credit risk 
    through its client base, insurance asset and other financial assets, the expected credit loss 
    is insignificant and has no impact on the Group.

 15.   ASSETS HELD FOR SALE 
        Since 2019, in line with the strategic objective to dispose of non-core assets, the Board 
        and Management have remained committed to the sale of Gem Diamonds Botswana (Pty) Ltd (GDB), 
        which owns the Ghaghoo diamond mine. Notwithstanding the lapsing in the prior year during 
        January 2020 of the initial sales agreement which was entered into in June 2019, management 
        remained committed and again opened the process to other prospective buyers and on 23 August 
        2021 entered into a binding share sale agreement with Okwa Diamonds (Pty) Ltd (Okwa Diamonds), 
        the entity with which an exclusivity agreement had been entered into in November 2020. Okwa 
        Diamonds, an SPV company registered in Botswana, which is owned by Vast Resources PLC (Vast), 
        a mining and resource development company listed on AIM (a sub-market of the London Stock 
        Exchange), and by Botswana Diamonds PLC (BOD), a diamond exploration and project development 
        company listed on AIM and the Botswana Stock Exchange. Vast and BOD are both parties to the 
        share sale agreement and guarantee the obligations of Okwa Diamonds. Under the share sale 
        agreement, the purchaser would pay a total consideration of US$4.0 million, payable in two 
        instalments of US$2.0 million each, the first of which would be payable five days after the 
        date on which the last suspensive condition is fulfilled or waived. 
 
        The suspensive conditions included obtaining the competition authority and regulatory approvals 
        within Botswana. The competition authority and regulatory conditions were fulfilled prior 
        to year end and written approvals were obtained from the Botswana Competition Authority and 
        the Ministry of Mineral Resources, Green Technology and Energy Security of Botswana. The agreement 
        had an initial longstop date of 31 January 2022. 
 
        In January 2022, after the reporting period, Vast informed Gem Diamonds and BOD that it did 
        not intend to continue with the transaction due to its inability to meet the funding suspensive 
        condition. BOD confirmed its commitment to conclude the transaction as originally envisaged 
        as soon as possible and has informed Gem Diamonds Limited that it has identified an alternative 
        financing partner which will, subject to any approvals that are required, replace Vast as 
        the initial financing partner. Gem Diamonds Limited and BOD remain committed to the sale of 
        GDB and are working together towards a mutually beneficial outcome and have agreed to extend 
        the longstop date from 31 January 2022 to 31 March 2022. 
 
        As the transaction was not successfully concluded by year end, GDB continued to be disclosed 
        as a discontinued operation held for sale at year end based on the circumstances detailed 
        above. 
 
        During the year, certain consumable inventory items which were not being used in the mine's 
        care and maintenance operations were written off relating to expired explosives and plant 
        consumables; underground mining consumables and spares and accessories for automotives no 
        longer on site. The asset held for sale is carried at carrying value which is lower than fair 
        value less costs to sell. The fair value is based on the unobservable market offer from the 
        potential buyer for the disposal group, accordingly the non-recurring fair value measurement 
        is included in level 3 of the fair value hierarchy. 
 
        The trading results of the operation continue to be classified as a discontinued operation 
        held for sale and are presented as follows:

 17.    INTEREST-BEARING LOANS AND BORROWINGS 
         A consolidated Group-wide refinancing of revolving credit facilities (RCF) took place during 
         the year with Nedbank Limited (acting through its Nedbank Corporate and Investment Banking 
         Division) (Nedbank) appointed as sole mandated lead arranger. Financial close of the three-year 
         RCF took place on 23 December 2021. The salient features of the new consolidated RCF are as 
         follows: 
          *    Three funders are participating in the RCF, namely 
               Nedbank (US$34.7 million), Standard Bank of South 
               Africa Limited (US$23.1 million) and Firstrand Bank 
               Limited (through their various operations) (US$19.2 
               million). All draw downs will be made in this same 
               ratio; 
 
 
          *    The RCF of Gem Diamonds Limited remains unchanged at 
               US$30.0 million and the Letšeng Diamonds RCF has 
               increased from LSL500.0 million (31 December 2020: 
               US$34.0 million) to US$47.0 million, made up of two 
               facilities of LSL450.0 million and ZAR300.0 million; 
 
 
          *    As at 31 December 2021, the RCF is unsecured; 
 
 
          *    On 28 February 2022, subsequent to year end, Gem 
               Diamonds Limited provided security for the RCF over 
               its bank accounts domiciled in the United Kingdom and 
               on 15 March 2022 the security over its 70% 
               shareholding in Letšeng Diamonds (carrying 
               value: US$256.2 million, which includes net cash and 
               short-term deposits of US$24.2 million) was 
               implemented. This security has the impact of 
               decreasing the interest rate margin on all facilities 
               by 1.5% from 15 March 2022 and converting the 
               facilities into secured facilities; 
 
 
          *    The Nedbank Limited portions of the RCF, being 
               US$13.5 million for Gem Diamonds Limited and ZAR300.0 
               million for Letšeng Diamonds are 
               Sustainability-linked loans, whereby the interest 
               rate can be reduced if certain sustainability 
               performance targets to be measured on 31 December 
               2022 and 31 December 2023 are achieved. This has had 
               no impact on the classification or measurement of 
               these facilities as at 31 December 2021; 
 
 
          *    The facilities also include an additional US$20.0 
               million accordion option for Gem Diamonds, the 
               utilisation of which is subject to all necessary 
               internal credit and other approvals from all funders. 
               There was no utilisation of this facility during the 
               current year. 
                                                                                                       2021       2020

  LSL215.0 million (US$13.5 million) bank loan facility at Letšeng Diamonds 
   This loan comprises two tranches of debt as follows: 
    *    Tranche A: Lesotho loti denominated LSL35.0 million 
         (US$2.2 million) term loan facility without Export 
         Credit Insurance Corporation (ECIC) support (five 
         years and six months tenure); and 
 
 
    *    Tranche B: South African rand denominated ZAR180.0 
         million (US$11.3 million) debt facility supported by 
         the ECIC (five years tenure). 
 
 
 
   The loan is an unsecured project debt facility which was signed jointly with Nedbank and the 
   ECIC on 22 March 2017 to fund the construction of the Letšeng mining support services 
   complex. The loan is repayable in equal quarterly payments which commenced in September 2018. 
   At year end LSL19.0million (US$1.2 million) (31 December 2020: LSL76.3 million (US$5.2 million)) 
   remains outstanding. 
 
   The South African rand-based interest rates for the facility at 31 December 2021 are: 
    *    Tranche A: 10.63% (31 December 2020: 10.10%); and 
 
 
    *    Tranche B: 7.03% (31 December 2020: 6.50%). 
 
 
 
   Total interest for the year on this interest-bearing loan was US$0.4 million (31 December 
   2020: US$0.6 million). 
 
   LSL450.0 million and ZAR 300.0 million (US$47.0 million) bank loan facility at Letšeng 
   Diamonds 
   Following the consolidated refinancing on 23 December 2021, the Group, through its subsidiary 
   Letšeng Diamonds, has a LSL450.0 million and ZAR300.0 million (US$47.0 million) three-year 
   revolving credit facility jointly with Nedbank Lesotho Limited, Standard Lesotho Bank Limited, 
   First National Bank of Lesotho Limited, Firstrand Bank Limited (acting through its Rand Merchant 
   Bank division) and Nedbank Limited (acting through its Nedbank Corporate and Investment Banking 
   division). 
 
   The facility expires on 22 December 2024 and has a 24-month renewal option. The LSL450.0 million 
   facility is subject to interest at the Central Bank of Lesotho rate plus 4.75% and the ZAR300.0 
   million facility is subject to South African JIBAR plus 4.55%. 
 
   The facility was unsecured as at 31 December 2021, however, following the implementation of 
   the security, subsequent to period end, on 15 March 2022, the interest rate will decrease 
   to Central Bank of Lesotho rate plus 3.25% and the ZAR300.0 million facility is subject to 
   South African JIBAR plus 3.05% respectively. There was no draw down on this facility at year 
   end. 
 
   Credit underwriting fees of US$0.5 million (31 December 2020: US$ nil) which were incurred 
   as part of the refinancing were capitalised to the Group's consolidated interest-bearing loans 
   and borrowings, albeit that Letšeng did not have any draw downs on its RCF at year end. 
   The capitalised fees will be amortised and accounted for as finance costs within profit or 
   loss over the period of the facility. Arranging fees of US$0.2 million which were incurred 
   as part of the refinancing were expensed to profit or loss for the year. 
 
   US$30.0 million bank loan facility at Gem Diamonds Limited 
   This new facility is a three-year RCF with Nedbank Limited (acting through its London branch), 
   Standard Bank of South Africa Limited (acting through its Isle of Man branch) and Firstrand 
   Bank Limited (acting through its Rand Merchant Bank division) for US$13.5 million, US$9.0 
   million and US$7.5 million, respectively. All draw downs will be made in these ratios. 
 
   The facility expires on 22 December 2024 and has a 24-month renewal option. 
 
   The previous RCF of US$30.0 million with Nedbank Limited which was due to expire on 31 December 
   2021, was replaced with the new RCF on 23 December 2021. On this date, the outstanding balance 
   on the previous RCF was US$15.0 million and after a capital repayment of US$6.0 million, the 
   new RCF was recognised at US$9.0 million. 
 
   At year end US$9.0 million (31 December 2020: US$10.0 million) had been drawn down resulting 
   in US$21.0 million (31 December 2020: US$20.0 million) remaining undrawn. Credit underwriting 
   fees of US$0.3 million (31 December 2020: US$0.3 million facility rolling fees) were capitalised 
   to the loan balance, resulting in the disclosure of a net US$8.7 million (31 December 2020: 
   US$9.7 million) loan balance. The capitalised fees will be amortised and accounted for as 
   finance costs within profit or loss over the period of the facility. Arranging fees of US$0.1 
   million which were incurred as part of the refinancing were expensed to profit or loss for 
   the year. 
 
   The US$-based interest rate for this facility at 31 December 2021 was 6.72% (31 December 2020: 
   5.22%) which comprises London US$ three-month LIBOR plus 6.50%. 
 
   The facility was unsecured as at 31 December 2021, however, following the implementation of 
   the security, subsequent to period end, on 15 March 2022, the interest rate will decrease 
   to London US$ three-month LIBOR plus 5.00%. 
 
   Total interest for the year on this interest-bearing RCF was US$1.0 million (31 December 2020: 
   US$1.2 million). 
 
   ZAR12.8 million (US$0.9 million) Asset-Based Finance facility 
   In January 2019, the Group, through its subsidiary, Gem Diamond Technical Services, entered 
   into a ZAR12.8 million (US$0.9 million) Asset Based Finance (ABF) facility with Nedbank Limited 
   for the purchase of a mobile X-Ray transmission machine (the asset). The asset serves as security 
   for the facility and has a carrying value of ZAR2.5 million (US$0.2 million) as at 31 December 
   2021 (31 December 2020: ZAR4.9 million (US$0.3 million)). At year end ZAR6.0 million (US$0.4 
   million) remains outstanding (31 December 2020: ZAR8.6 million (US$0.6 million)). The facility 
   is repayable over five years and bears interest at the South African Prime Lending rate, which 
   was 7.25% at 31 December 2021 (31 December 2020: 7.0%).

    Lease payments comprise payments in principle of US$1.7 million (31 December 2020: US$1.9 
    million) and repayments of interest US$0.5 million (31 December 2020: US$0.6 million). 
 
    The Group recognised variable lease payments of US$50.0 million (31 December 2020: US$41.4 
    million) for the year ended 31 December 2021 which consist of mining activities outsourced 
    to a mining contractor. Total costs incurred for the year amount to US$50.0 million (31 December 
    2020: US$41.4 million) of which US$41.5 million (31 December 2020: US$34.1 million) has been 
    capitalised to the Stripping Asset. Refer Note 1.2.6, Property Plant and equipment, Note 1.2.28, 
    Critical accounting estimates and judgements, Equipment and service lease, Note 4, Operating 
    profit. 
 
    During the year, the lease relating to backup power generating equipment at Letšeng expired 
    and was therefore derecognised. A new lease for back-up power generating equipment is in the 
    process of being negotiated. In the interim, Letšeng is renting existing backup power 
    generator equipment on a month-to-month basis, which amounted to US$0.4 million for the year 
    which has been included in profit or loss.

    1 The severance pay benefits arise due to legislation within the Lesotho jurisdiction, requiring 
    that two weeks of severance pay be provided for every completed year of service, payable on 
    retirement. 
    2 These amounts are mainly non-interest bearing and are settled in accordance with terms agreed 
    between the parties. 
    3 These amounts were presented on a net basis in the prior year and have been disaggregated 
    and presented separately in the current year. 
 
    Royalties consist of a levy paid to the Government of the Kingdom of Lesotho on the value 
    of diamonds sold by Letšeng. Withholding taxes consist of taxes paid on dividends and 
    other services to the Lesotho Revenue Authorities. 
 
    The carrying amounts above approximate fair value.

  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 LoM 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 9.8% (31 December 2020: 9.7%), estimated rehabilitation timing of 
   14 years (31 December 2020: 15 years) and an inflation rate of 5.3% (31 December 2020: 5.3%). 
   At Ghaghoo (Refer Note 15, Asset held for sale), management used the available estimated costs 
   to rehabilitate, considering its care and maintenance state. The decrease in the provision 
   at Letšeng is mainly attributable to the annual reassessment of the estimated closure 
   costs performed at the operations together with the ongoing rehabilitation spend during the 
   year at Letšeng.

    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$99.5 million (31 December 
    2020: US$97.1 million). There are no income tax consequences attached to the payment of dividends 
    by Gem Diamonds Limited to its shareholders. 
 
    The Group, excluding Ghaghoo, has estimated tax losses of US$40.3 million (31 December 2020: 
    US$34.0 million). All tax losses are generated in jurisdictions where tax losses do not expire. 
    No deferred tax assets were recognised on these losses as management do not foresee any taxable 
    profits or taxable temporary differences against which to utilise these.

 24.    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                                                                                     145        162 
  - After one year but not more than five years                                                         760        695 
  - More than five years                                                                                784        993

        Equipment and service lease 
        The Group has 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 are variable in 
        nature. 
        A portion of the lease payment is therefore expensed in the Consolidated statement of 
        profit 
        or loss and the portion relating to waste removal/stripping costs is 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 1.2.28, Critical accounting 
        estimates. 
        The terms of this lease are negotiated during the extension option periods catered for 
        in 
        the agreements or at any time sooner if agreed by both parties.

        Multi-aggregate protection policy 
        The Group, through its subsidiary Letšeng entered into a LSL100.0 million (US$6.2 
        million) 
        Multi-aggregate Protection Insurance Policy with the Lesotho National Insurance Group 
        (LNIGC) 
        on 1 October 2021. This policy has a tenure of 4 years and 9 months, consisting of five 
        premium 
        payments of LSL20.0 million (US$1.3 million), each payable annually in advance. As at 31 
        December 
        2021 the Group has committed to making the four remaining premium payments, as well as 
        the 
        annual insurance risk finance service fee of 7% on an annual premium of LSL1.4 million 
        (US$0.1 
        million) 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 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 
        In terms of the mining agreement entered into between the Group and the Government of 
        the 
        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.

  The main capital expenditure approved relates to the investment in the new primary crushing 
   area at Letšeng of US$15.0 million. Other smaller capital expenditure, all at Letšeng, 
   relates to investment in continued tailings storage extension of US$1.3 million (31 December 
   2020: US$1.0 million), the construction of an employee centre of US$0.8 million linked to 
   the successful completion of the Business Transformation target, further mineral resource 
   and reserve studies of US$0.5 million and detailed engineering designs relating to the new 
   primary crushing area of US$0.5 million. The expenditure is expected to be incurred over the 
   next 12 months. 
 
   Contingent rentals - Alluvial Ventures 
   The contingent rentals represent the Group's obligation to a third party (Alluvial Ventures) 
   for operating a third plant on the Group's mining property at Letšeng Diamonds. The rental 
   is determined when the actual diamonds mined by Alluvial Ventures are sold. The agreement 
   is based on 39.5% to 60% (2020: 39.5% to 60%) of the value (after costs) of the diamonds recovered 
   by Alluvial Ventures and is limited to US$1.4 million (2020: US$1.4 million) per individual 
   diamond. As at the reporting date, such future sales cannot be estimated reliably due to the 
   variability within these estimations. 
 
   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$0.2 million (December 2020: US$0.2 million). 
 
   The Group monitors possible tax claims within the various jurisdictions in which the Group 
   operates. Management applies judgement in identifying uncertainties over tax treatments and 
   concluded that there were no uncertain tax treatments relating to the current year. Refer 
   Note 1.2.28, Critical accounting estimates and judgements. There remains a risk that further 
   tax liabilities may potentially arise. 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.

 ----------------------------------------------------------------------------        ------------------  ------------- 
 
        Jemax Management (Proprietary) Limited provided administrative services with regards to the 
         mining activities undertaken by the Group. A controlling interest is held by an Executive 
         Director of the Company. 
 
         The transaction relating to the non-executive director was for the sale of a polished diamond. 
         All proceeds were received prior to year end. 
 
         The above transactions were made on terms agreed between the parties and were made on terms 
         that prevail in arm's length transactions. 
 
 26.    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 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 2021, the Group had US$74.3 million (31 December 2020: US$60.8 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 17, Interest bearing loans and borrowings for detail on the debt facilities in 
         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. 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 the 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 
                                      2021 and 31 December 2020. 
 
 
 
                                There has been no change in the assumptions or method applied from the prior year. 
 
                                Sensitivity analysis 
                                At year-end, Letšeng had US$22.1 million (2020: US$31.1 million) cash on hand 
                                held in 
                                US$. If the US dollar had appreciated/ (depreciated) by 10% against the LSL, the 
                                Group's profit 
                                before tax and equity at 31 December 2021 would have been US$2.4 million 
                                higher/(lower) (31 
                                December 2020: US$2.8 million). 
                 (iii)          Forward exchange contracts 
                                From time to time, the Group enters into forward exchange contracts to hedge the 
                                exposure 
                                to changes in foreign currency of future sales of diamonds at Letšeng Diamonds. 
                                The Group 
                                performs no hedge accounting. At 31 December 2021, the Group had no forward exchange 
                                contracts 
                                outstanding (31 December 2020: US$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 
                                80 basis points (2020: 80 basis points) during the year, profit before tax and equity 
                                would 
                                have been US$0.1 million (lower)/higher (31 December 2020: US$0.1 million). The 
                                assumed movement 
                                in basis points is based on the currently observable market environment, which 
                                remained consistent 
                                with the prior year and assumed a continued impact of the COVID-19 pandemic for the 
                                year. 
        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 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 2021 and 31 December 2020 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, 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 debt facilities of US$74.3 million at year end (2020: US$60.8 million). 
 
                  The table below summarises the maturity profile of the Group's financial liabilities at 31 
                  December based on contractual undiscounted payments, excluding discontinued operation:

   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. The fair value of share options granted is 
    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 takes into account projected 
    dividends and share price fluctuation co-variances of the Company. 
 
    There is a nil or nominal 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 are three awards where options are still outstanding. 
 
    All four awards were awarded on the following basis: 
 
    To key employees (excluding Executive Directors): 
     *    the awards vest 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 awards vest, they are exercisable for seven 
          years (i.e. contractual term is 10 years); and 
 
 
     *    the vested awards are equity settled. 
 
 
 
    To Executive Directors: 
     *    the awards vest 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 awards granted are 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 awards vest, they are exercisable for seven 
          years (i.e. contractual term is 10 years); and 
 
 
     *    the vested awards are equity settled. 
 
 
 
    The fair value of the Nil value awards is based on the observable Gem Diamonds Limited share 
    price on the date of award with no adjustments to the price made.

       ---------------------------------------------------------------------------------------  ----------  ---------- 
 
          The 2020 proposed dividend was approved on 2 June 2021 and a final cash dividend of 2.5 US 
          cents per share was paid to shareholders on 15 June 2021. 
 
          A proposed ordinary cash dividend of 2.7 US cents per ordinary share for 2021 is subject to 
          approval at the AGM to be held on 8 June 2022 and is not recognised as a liability as at 31 
          December. 
 30.    EVENTS AFTER THE REPORTING PERIOD 
         Events which occurred after the reporting period relating to the discontinued operation and 
         the status of the sales process have been disclosed in Note 15 Assets held for sale. These 
         events did not require any adjustments to the financial statements. 
 
         Events which occurred after the reporting period relating to the successful implementation 
         of the security on certain revolving credit facilities within the Group have been disclosed 
         in Note 17 Interest-bearing loans and borrowings. These events did not require any adjustments 
         to the financial statements. 
 
         On 23 February 2022, the South African corporate income tax rate was reduced from 28% to 27% 
         for companies with years of assessment ending on or after 31 March 2023. The change in tax 
         rate will affect recorded deferred tax assets and liabilities and effective tax rate in the 
         future. The new corporate tax rate of 27% is considered to be substantively enacted on 23 
         February 2022 and is expected to not have a material impact on the Group. This event did not 
         require any adjustment to the financial statements and will be applicable to Gem Diamonds 
         Technical Services, the Group's South African subsidiary. 
 
         Progress relating to the amended tax assessment issued to Letšeng by the LRA has been 
         disclosed in Note 1.2.28 Critical accounting estimates and judgements. 
 
         An ordinary cash dividend of 2.7 US cents for the 2021 financial year has been proposed. This 
         is subject to approval at the AGM to be held on 8 June 2022. 
 
         No other fact or circumstance has taken place between the end of the reporting period and 
         the approval of the financial statements which, in our opinion, is of significance in assessing 
         the state of the Group's affairs or requires adjustments or disclosures.

         Financial information of Letšeng Diamonds, a 70% held subsidiary which has a material
