遠西黃金回收(專有)有限公司文件編號:PR/SMI/1330/23 117 22.解釋和結論項目22項目24提供了編制技術報告所使用的所有技術文件的完整清單。QP在編制礦產資源和礦產儲量估算的過程中詢問了所有這些信息,並對LOM規劃的技術經濟價值以及所執行的信息和研究工作的完整性感到滿意。QP認為,在當前方法和系統的背景下,FWGR的業務是相當穩健的。這些業務正在進行中,有一支經驗豐富的管理團隊、技術熟練的員工和一名採礦承包商,他們的記錄證明瞭所需的能力。除本文所指的風險可控的不確定性外,並無發現任何營運或地質冶金性質的因素會對最終經濟開採的前景或所述礦產儲量的有效性造成重大影響。QP對用於經濟評估的1,081,261茲羅提/公斤(即1,934美元/盎司,按17.39茲羅爾/美元計算)的金價感到滿意。此價格由DRDGold提供,與2023年6月30日的現貨價格1,173,183.94 ZAR1,173,183.94 ZAR1,173,183.94(即1,806.89美元/盎司,按ZAR18.78/U.S.計算)並無出入。Sound Mining已經審查了所提供的EIA和EMP。FWGR持有的資產是從Sibanye-Stillwater的子公司Sibanye Gold收購的,交易確立了對包含礦產資源和礦產儲量的各種尾礦壩的普通法所有權。礦業局除其他外,根據環境保護局和“礦山健康和安全條例”的規定開展活動。與Sibanye Gold簽訂的使用和訪問協議明確規定了Sibanye Gold持有的各種權利、許可和許可證,FWGR根據這些權利、許可和許可證進行運營,等待將可轉讓的權利、許可和許可證轉讓給FWGR。勘探計劃的鑽探、取樣、分析流程和管理是適當的,並符合行業最佳實踐。他們被認為是高度自信的。用於根據體積確定數量的密度是根據現場測量值和經驗數據確定的,被認為是可靠的。聲音挖掘得出的結論是,這些估計是基於一個合適的可靠信息數據庫。對LOM計劃的審查表明,回收率與冶金測試工作中實現的回收率一致,使用的數量和品位與礦產資源估計中估計的數量和品位一致。對DP2處理的回顧表明,該廠的表現符合預期,經過進一步的修改,將足以應對計劃中的第二階段產能增加到1.2Mtpm。擴建的設計基於具有代表性的和充分的冶金數據、知識和見解。工廠的質量平衡是適當的。DP2產生的尾礦材料將儲存在Driefontein 4 TSF,直到RTSF投產,沉積速率為2.4Mtpm,最終透視能力為800Mt。Sound Mining已經審查了FWGR專家為RTSF準備的設計,並得出結論,詳細的設計報告為未來安全RTSF的發展提供了堅實的基礎。已經審查了所有必要基礎設施所需的資本撥備,並認為這是適當的。已經進行了擴大DP2和區域業務框架的資本支出估計數,目前以PFS的準確度列報。業務支出是根據當前業務的實際數據估算的。這些估計被認為是適當的,符合行業標準。QP雖然認識到第12.1項確認的風險,但仍信納FWGR的礦產資源及礦產儲量不太可能因這些不確定因素而有重大變化。23.建議項目23 QPS建議FWGR繼續及時主動地為RTSF尋求必要的監管批准,以確保預測的生產能夠不間斷地繼續進行。

遠西黃金回收(專有)有限公司文件編號:PR/SMI/1330/23 120術語解釋白雲石碳酸鹽礦物,CaMG(CO3)2。白雲石一詞也用於描述沉積碳酸鹽巖,它主要由礦物白雲巖Doréan未精煉的、因此不純的金合金和不同數量的銀和少量賤金屬組成,在交付給精煉廠以升級到倫敦良好的交付標準之前,通常包括平均85%的金,為勘探和評估地下地質的目的而鑽探。在這種情況下,金礦脈的存在和分佈巖漿注入平面軟弱帶形成的垂直或近垂直的火成巖體,如與圍巖的層理或面理不一致的斷層或裂隙估計可變勘探、採樣、測繪、鑽探和其他工作的定量判斷參與尋找成礦相的沉積特徵的總和,其特徵為沉積在特定環境中沉積;一種被認為是在相似的温度和壓力條件下形成的變質巖組合斷層地球物質中的一種斷裂,沿着斷裂的兩邊平行於運動平面移動火焰法分析金屬礦石的方法需要利用採場或礦體底側的溪流或河流的作用產生的熔爐熱流作用產生的熔爐熱流金礦金礦牀定義在一個地理上不同的子盆地中的含金礦牀花崗巖一種侵入長英質巖石,其結構是粒狀的,熱液作用於熱水的循環。一般來説,這發生在火山活動附近,表明礦產資源是礦產資源的一部分,其數量和等級或質量是根據充分的地質證據和採樣來估計的。與指定礦產資源相關的地質確定性水平足以讓合資格的人士充分詳細地應用修正因素,以支持礦山規劃和對礦牀的經濟可行性進行評估。由於指示礦產資源的置信度低於測量礦產資源的置信度,因此指示礦產資源只能轉換為可能的礦產儲量。推斷礦產資源是礦產資源的一部分,其數量、品位或質量是根據有限的地質證據和採樣來估計的。與推斷的礦產資源有關的地質不確定性水平太高,無法應用可能影響經濟開採前景的相關技術和經濟因素,從而有助於評估經濟可行性。由於推斷礦產資源的地質置信度是所有礦產資源中最低的,因此無法以有助於評估經濟可行性的方式應用修正係數,因此在評估採礦項目的經濟可行性時,可能不考慮推斷礦產資源,也不能將其轉換為礦產儲量。卡魯:南非的一個大片半沙漠自然區,因其地質上的卡魯超羣而得名,常被用來描述145 Ma至360 Ma的年代,這是一種在確定礦產資源時使估計誤差最小化的插值法。與所測量礦產資源相關的地質確定性水平足以讓合資格人士應用足夠詳細的修正因素,以支持詳細的礦山規劃和對礦藏經濟可行性的最終評估。由於測量礦產資源的置信度高於指示礦產資源或推斷礦產資源的置信度,因此可將測量礦產資源轉換為已探明礦產儲量或可能礦產儲量。可開採礦產資源中在技術上和經濟上可行的那部分礦產資產(S)任何已被授予的勘探和/或採礦權利(“財產”),或持有該財產或該實體證券的任何其他權利,包括但不限於所有物質和無形財產、礦業權、採礦權、採礦租約、知識產權、個人財產(包括工廠設備和基礎設施)、採礦和勘探所有權及所有權或因發現和開採位於地殼內、之上或附近的礦物和石油而持有或獲得的任何其他權利。礦產資產可分為閒置礦產、勘探礦產、開發礦產、採礦礦產或廢棄礦產。礦產儲量是對已指示和已測量礦產資源的噸位和品位或質量的估計,在合格投資者看來,這些資源可以作為經濟上可行的項目的基礎。更具體地説,指已測量或指示的礦產資源中經濟上可開採的部分,包括稀釋材料和在開採或提取材料時可能發生的損失的補償。 確定測量或指示的礦產資源的一部分具有經濟可行性必須基於QP應用

Far West Gold Recoveries (Proprietary) Limited Document No: PR/SMI/1330/23 109 19. ECONOMIC ASSESSMENT Item 19 (i); (ii); (iii) and (iv) A Discounted Cashflow (DCF) modelling approach was adopted to assess the economic viability of the Mineral Reserves as stated. Considering the stage of development of the operation and the uncertainties of future global economics, as well as exchange rate, interest rate and gold price uncertainties, a real DCF model is deemed more appropriate than a nominal DCF model. The DCF model was generated in June 2023 South African Rand (ZAR) real terms and is based on the revenue forecast, associated capital and operating cost forecasts, and on appropriate and reasonable economic assumptions (Table 30). Table 30: Inputs to the DCF Model Description Quantum Unit Key Dates Money Terms 30 June 2023 Planned Capacity DP2 Expansion Mtpm 1.2 LoM LoM considering a 1.2Mpta Operation Years 18 Contingencies Contingency % 15% Gold Price ZAR/USD ZAR/USD 17.39 USD/oz Gold USD/oz 1,934 ZAR/kg Gold ZAR/kg 1,081,261 Source: Sound Mining, 2023; and FWGR, 2023 These assumptions are based on information received from FWGR and from the various consultants who contributed to the Mineral Resources, LoM planning and technical study-work that underpin the 30 June 2023 Mineral Reserve estimate. The economic assessment assumes a 100% equity-based business and ignores the effect of working capital changes. The QP is satisfied with the quality of this information, including the revenue and cost forecasts, and considers the inputs to the DCF model to constitute an overall PFS level of accuracy (i.e., +/-25%). 19.1. Revenue Forecast The revenue forecast is a function of gold sales and the pricing assumptions used for the economic assessment. The following processing recoveries, which are supported by test work and current plant performance data, were applied to the material from the respective TSFs to compute the amount of gold sold: • 49.5% for Driefontein 5 TSF material; • 56.6% for Driefontein 3 TSF material; • 50.5% for Kloof 1 TSF material; • 47.2% Libanon TSF material; • 62.5% for Venterspost South TSF material; and • 54.7% for Venterspost North TSF material. The expansion of DP2 facilitates an increase in gold sales over time (Graph 11 and Error! Reference source not found.).
Far West Gold Recoveries (Proprietary) Limited Document No: PR/SMI/1330/23 110 Graph 11: Gold Sales Forecast Source: Sound Mining, 2023 Processing throughput can continue after FY2041 when the available TSFs are likely to be incorporated into the operation. At this stage, the economic assessment has only considered the depletion of the TSFs that comprise the current Mineral Reserves. The gold sold from these TSFs equate to approximately 1.2Moz. The real revenue forecast relies on a gold price of ZAR1,081,261/kg (i.e., USD1,934/oz at ZAR17.39/USD). Taxes would be determined using the gold mining tax formula with all unredeemed capital taken into account. The assets are part of the ongoing business of FWGR, which fall outside the ambit of the provision of the MPRDA that would place an obligation to pay royalties on the proceeds of the operations. 19.2. Cashflows Graph 12 presents the post-tax cashflow for an operation that excludes the benefits that would eventually be derived from the Available TSFs (see Error! Reference source not found.).

Far West Gold Recoveries (Proprietary) Limited Document No: PR/SMI/1330/23 111 The cumulative post-tax cashflows over the LoM remain positive. When assuming a discount rate of 10.96% the unleveraged operation reflects a NPV of ZAR2.27 Billion. FWGR is an ongoing operation and thus the Internal Rate of Return (IRR) and a capital payback period are not applicable. 19.3. Sensitivities The achievability of the LoM plans, budgets and forecasts cannot be assured as they are based on economic assumptions, many of which are beyond the control of the company. Future cashflows and profits derived from such forecasts are inherently uncertain and actual results may be significantly more or less favorable. The technical risks as identified by Sound Mining are provided in Item 12.1. These and other environmental risks can impact the anticipated revenue and cost forecasts and accordingly have been assessed against upside or downside changes of between -20% and +20%. The consequential potential impacts are presented in Table 31 and is illustrated graphically in Graph 13.

Concluding Comments The QP is satisfied that the Mineral Reserves as stated are all economically viable. 20. ADJACENT PROPERTIES Item 20 (i); (ii); (iii) and (iv) A discussion of the characteristics of adjacent properties is usually relevant for in situ mineral deposits. The TSF assets are independent from adjacent properties with no correlation in mineralization.
Far West Gold Recoveries (Proprietary) Limited Document No: PR/SMI/1330/23 113 21. OTHER RELEVANT DATA AND INFORMATION Item 21 Information relevant to the Mineral Resource and Mineral Reserve statements will certainly include the prevailing legislative framework in South Africa. 21.1. South African Minerals Policy and Legislative Framework The South African Government has an extensive legal framework within which mining, environmental and social aspects are managed. Inclusive within the framework are international treaties and protocols, and national acts, regulations, standards, and guidelines which address international, national, provincial and local management areas. The role of the Government and the relevant regulatory authorities can be summarized as follows: • the custodian of environmental and mining legislation as a Constitutional imperative; • a conduit between the public and mining companies to ensure that mineral rights holders satisfy the objectives of transforming the mining industry by, inter alia, increasing the number of black people in the industry to reflect the country’s population demographics, to empower and enable them to meaningfully participate in and sustain the growth of the economy; thereby ensuring transparency to achieve accelerated and shared economic growth; • advocate of sustainable development, from a socio-economic and environmental management perspective; and • ultimate custodian of historical mining legacies, inclusive of abandoned mines. The Government has significantly reformed its environmental legislation. The driving force behind this is the need to support the overall national objective of sustainable development. Most recently, in 2015, the government published the National Environmental Management Laws Amendment Bill for public comment and the Draft Revised Financial Provision Regulations were published in General Notice No.: R1228 of 10 November 2017 in Government Gazette No.: 41236 in respect of prospecting, exploration and mining or production operations. The applicable laws are listed below: • The Constitution of South Africa (Act No. 108 of 1996); • Mines and Works Act, 1956 (Act No. 27 of 1956); • the Mine Health and Safety Act, 1996 (Act No. 29 of 1996); • the National Environmental Management Act, 1998 (Act No. 107 of 1998) (NEMA); • National Water Act, 1998 (Act No. 36 of 1998) (NWA); • National Nuclear Regulator Act, 1999 (Act No. 47 of 1999) (NNRA); • National Environmental Management: Biodiversity Act, 2004 (Act No. 10 of 2004); • National Environmental Management: Air Quality Act, 2004 (Act No. 39 of 2004); • National Environmental Management: Waste Act, 2008 (Act No. 59 of 2008) (NEM:WA); • the Competition Act, 1998 (Act No. 89 of 1998); • the Companies Act, 2008 (Act No. 71 of 2008); • Mineral and Petroleum Resources Development Act, 2002 (Act No. 28 of 2002) (MPRDA); • Mineral and Petroleum Resources Royalty Act, 2008 (Act No. 28 of 2008) (MPRRA); • Mining Titles Registration Act, 1967 (Act No. 16 of 1967); • Mining Titles Registration Amendment Act, 2003 (Act No. 24 of 2003); • Broad-Based Socio-Economic Charter (and associated amendments, 2010), also known as the Mining Charter; • National Heritage Resources Act, 1999 (Act No. 25 of 1999) (NHRA); • National Environmental Management: Protected Areas Act, 2003 (Act No. 57 of 2003) (NEM:PAA); • National Environmental Management: Biodiversity Act, 2004 (Act No. 10 of 2004) (NEM:BA); • National Forests Act, 1998 (Act No. 30 of 1998) (NFA);

South African Legislative Framework South African legislation applicable to mining related activities and specifically with regard to environmental, social and community impact issues are: • The Constitution of South Africa Act, 1996 (Act No. 108 of 1996); • Mineral and Petroleum Resources Development Act, 2008 (Act No. 28 of 2002) (MPRDA); • National Environmental Management Act, 1998 (Act No. 107 of 1998) (NEMA); • National Water Act, 1998 (Act No. 36 of 1998) (NWA); • National Environmental Management: Waste Act, 2008 (Act No. 59 of 2008) (NEM:WA); • National Environmental Management: Air Quality Act, 2004 (Act No. 39 of 2004) (NEM:AQA); • Hazardous Substances Act, 1973 (Act No. 15 of 1973) (HSA); • National Heritage Resources Act, 1999 (Act No. 25 of 1999) (NHRA); • National Environmental Management: Protected Areas Act, 2003 (Act No. 57 of 2003) (NEM:PAA); • National Environmental Management: Biodiversity Act, 2004 (Act No. 10 of 2004); and • National Forests Act, 1998 (Act No. 30 of 1998) (NFA). A brief description of the above Acts is summarized below: The Constitution of South Africa Act, 1996 (Act No. 108 of 1996): Mines must comply with South African constitutional and common law by conducting their operational and closure activities with due diligence and care for the rights of others. Section 24(a) of the Constitution states that everyone has the right to (a) an environment which is not harmful to their health or well-being; and (b) to have the environment protected, for the benefit of present and future generations, through reasonable legislative and other measures that: • prevent pollution and ecological degradation; • promote conservation; and • secure ecologically sustainable development and use of natural resources. Mineral and Petroleum Resources Development Act, 2002 (Act No. 28 of 2002) (MPRDA): The MPRDA provides a holistic cradle-to-grave approach to prospecting and mining by fully considering economic, social and environmental costs to achieve sustainable development of South African Mineral Resources. National Environmental Management Act, 1998 (Act No. 107 of 1998) (NEMA): NEMA was promulgated in 1998 to replace the Environmental Conservation Act, 1989 (Act No. 73 of 1989) (ECA) as the overarching national environmental legislative framework. NEMA was promulgated to give effect to the Environmental Management Policy (published in 2007), and has been subsequently amended, including the National Environmental Management Amendment Act of 2003, and the National Environmental Management Second Amendment Act, 2004 (Act No. 8 of 2004).
Far West Gold Recoveries (Proprietary) Limited Document No: PR/SMI/1330/23 115 The requirements for financial provisions for rehabilitation and closure are evolving. Historically, closure and rehabilitation liability calculations and financial provisions had to be determined and provided for in accordance with Regulations 53 and 54 under the MPRDA (GN 527, April 2004), a guideline document for the evaluation of the quantum of closure-related financial provisions issued by the DMRE in 2004/5, and a set of master rates updated from time to time by the DMRE based on inflation. Financial provision regulations (GNR 1147) were published on November 2015 (as amended January 2020) to replace Regulations 53 and 54 under the MPRDA. The new regulations require the following: • annual rehabilitation, as reflected in an annual rehabilitation plan; • final rehabilitation, decommissioning and closure of the prospecting, exploration, mining or production operations at the end of the life of operations, as reflected in a final rehabilitation, decommissioning and mine closure plan; and • remediation of latent or residual environmental impacts which may become known in the future, including the pumping and treatment of polluted or extraneous water; as reflected in an environmental risk assessment report; and • the applicant or holder of a right or permit must ensure that the financial provision is, at any given time, equal to the sum of the actual costs of implementing the plans and report contemplated in regulation 6 and regulation 11 (1) for a period of at least 10 years forthwith. The NEMA Section 24P (as amended in April 2014) also applies. It requires: • financial provisions to be made in the prescribed manner before an environmental authorization is issued by the DMRE; • annual assessment of environmental liabilities; and • annual “increase” of available financial provisions to the satisfaction of the Minister of Mineral Resources. National Water Act, 1998 (Act No. 36 of 1998) (NWA): The NWA stipulates that a WUL is required for the abstraction, storage, use, diversion, flow reduction and disposal of water and effluent in terms of Section 21 of the Act. Use of water for mining and related activities is also regulated through regulations that were updated after the promulgation of the NWA in 1999 - GN 704. GN 704 addresses the regulations on use of water for mining and related activities aimed at the protection of water resources. Inclusive within GNR 704 are the control measures for activities and its regulation of the sizing, control and monitoring of water management measures. National Environmental Management: Waste Act, 2008 (Act No. 59 of 2008) (NEM:WA): Waste management activities listed in terms of the NEM:WA (GN 921, 29 November 2013) include: storage of waste; the reuse, recycling and recovery of waste; treatment of waste; and disposal of waste at specified thresholds. Historically, mine residues were managed in accordance with the MPRDA and the NEMA. This situation changed in 2014 with the promulgation of the National Environmental Management: Waste Amendment Act of 2014 and its inclusion of mine residue as a Category A (hazardous) waste, as well as the addition of mine residue stockpiles and residue deposits to the list of waste management activities requiring a WML. In 2008, the Ministers of Mineral Resources and Environmental Affairs concluded an agreement on the “One Environmental System” for the country with respect to mining. Ministers adopted an integrated mine environmental management system and sought to align the MPRDA, NEMA, NEM:WA, NEM:AQA and NWA. In short, the agreement implied that environmental issues resulting from mining, prospecting, production and related activities will be regulated in terms of the NEMA, whilst the Minister of Mineral Resources will become a competent authority in terms of NEMA. Following the acceptance of the above-mentioned agreement various amendments were made to environmental legislation, inter alia, the NEMA, MPRDA and NEM:WA. Significant to these amendments were the inclusion of residue stockpiles under the NEM:WA listed activities as well as the publication of regulations regarding the planning and management of residue stockpiles and residue deposits from the prospecting, mining, exploration or production operation in GNR 632 of 2015 and GN 921 July 2015.
Far West Gold Recoveries (Proprietary) Limited Document No: PR/SMI/1330/23 116 Transitional provisions specifically include the following: • any activity in terms of regulation 73 of the MPRDA relating to the management of residue stockpiles and residues deposits, that can be done in terms of a provision of GNR 632 of 2015, must be regarded as having been done in terms thereof; • management measures of residue stockpiles and residue deposits approved in terms of the MPRDA, at the time of the coming into operation of GNR 632 of 2015, must be regarded as having been approved in terms thereof; • a holder of a right or permit in terms of the MPRDA must continue the management of the residue stockpiles and residue deposits in accordance with the approved management measures; and • a person who lawfully conducts a waste management activity listed in the NEM:WA Schedule on the date of the coming into effect of this Notice may continue with the waste management activity until such time that the Minister by notice in a Gazette calls upon such a person to apply for a WML. National Environmental Management: Air Quality Act, 2004 (Act No. 39 of 2004) (NEM:AQA): In terms of Section 21 of the NEM:AQA, an Atmospheric Emissions License (AEL) is required for listed processes that may result in atmospheric emissions, which may have a significant detrimental effect on the environment, health, social and economic conditions. These requirements apply to smelters, refineries and certain processing plants. NEM:AQA GN 283 April 2015 requires mines to register with the Department and submit results in-line with the National Atmospheric Emission Inventory System (NAEIS) requirements. The National Dust Control Regulations (GNR 827, 1 November 2013) provides standards for dust-fall in residential and non-residential areas, and the requirements of monitoring and reporting to the air quality officer. Mining operations have the responsibility to comply with the standards. Hazardous Substances Act, 1973 (Act No. 15 of 1973) (HSA): The regulations relating to Group IV Hazardous Substances (GNR 247 of 26 February 1993) in terms of the HSA apply to the use and transportation of radioactive nuclides used in metallurgical processing plants. National Heritage Resources Act, 1999 (Act No. 25 of 1999) (NHRA): The NHRA requires that a heritage assessment be undertaken for developments listed in the Act. The Act prohibits the following: the alteration, disturbance, damage or demolishment of buildings and structures older than 60 years; archaeological and paleontological artefacts; cultural significant graves and burial sites; and public monuments, except for where a permit was issued by the relevant Provincial Heritage Resources Authority. National Environmental Management: Protected Areas Act, 2003 (Act No. 57 of 2003) (NEM:PAA): The NEM:PAA regulates the system of protected areas in South Africa and their management. It distinguishes between the following types of protected areas: national parks; nature reserves; special nature reserves; and ‘protected environments. Mining is prohibited in national parks, nature reserves and special nature reserves, but mining in ‘protected environments’ may be allowed with the necessary permission from the Minister of Environmental Affairs as well as the Minister of Mineral Resources. National Environmental Management: Biodiversity Act, 2004 (Act No. 10 of 2004) (NEM:BA): Holders of a mining right need to comply with the alien and invasive species regulations (GNR 598 of 1 August 2014) in terms of NEM:BA for species listed in GN 864, of 29 July 2016, which deal with different categories of alien and invasive plant and animal species that are prohibited, must be combatted or eradicated, controlled, require a permit or are subject to certain exemptions and prohibitions. National Forest Act, 1998 (Act No. 84 of 1998) (NFA): The NFA prohibits the cutting, disturbance, damage or destruction of trees in natural forests and trees included in the lists of protected tree species published in terms of the NFA, except where a license was issued by the Department of Agriculture Forestry and Fisheries (DAFF).
Far West Gold Recoveries (Proprietary) Limited Document No: PR/SMI/1330/23 117 22. INTERPRETATIONS AND CONCLUSIONS Item 22 A full list of all technical documents used in the compilation of the TRS is provided in Item 24. The QP has interrogated all of this information in the process of generating the Mineral Resource and Mineral Reserve estimates and remains satisfied with the technoeconomic merits of the LoM planning and of the integrity of the information and study-work performed. The QPs are of the opinion that the operations of FWGR are reasonably robust in the context of the current methodologies and systems. These operations are ongoing with an experienced management team, skilled employees and a mining contractor whose track record demonstrates the required competence. Apart from the uncertainties identified herein, which risks are manageable, no factors of an operational or geo-metallurgical nature have been identified that could significantly impact the prospects for eventual economic extraction, or the validity of the Mineral Reserves as stated. The QP is comfortable with the gold price of ZAR1,081,261/kg (i.e., USD1,934/oz at ZAR17.39/USD) used for the economic assessment. This price was provided by DRDGOLD and is not inconsistent with the spot price as at 30 June 2023 of ZAR1,173,183.94/kg (i.e., USD1,806.89/oz at ZAR18.78/USD). Sound Mining has reviewed the EIA and EMP that were provided. The assets held by FWGR were acquired from Sibanye Gold, a subsidiary of Sibanye-Stillwater, in a transaction in which common law ownership was established over the various tailings dams containing the Mineral Resources and Mineral Reserves. FWGR conducts its activities inter alia in accordance with EAs and the provisions of the Mine Health and Safety regulations. A Use and Access Agreement with Sibanye Gold articulates the various rights, permits and licenses held by Sibanye Gold in terms of which FWGR operates, pending the transfer to FWGR of those that are transferable. The drilling, sampling, analytical processes and governance of the exploration programs are appropriate and in-line with industry best practice. They are considered to be of high confidence. The density used to determine quantities from volumes has been determined from both in situ measured values and empirical data and is considered reliable. Sound Mining concludes that the estimations are based on a suitable database of reliable information. Scrutiny of the LoM plan has shown that the recoveries coincide with the recoveries achieved in the metallurgical test work and the quantities and grades used are consistent with those estimated in the Mineral Resource estimation. A review of the processing at DP2 reveals that the plant has performed in-line with expectations, and with further modifications, will adequately handle the planned increase in throughput to 1.2Mtpm for Phase 2. The design for the expansion is based on representative and adequate metallurgical data, knowledge and insights. The mass balance for the plant is appropriate. The tailings material arising from DP2 will be stored at the Driefontein 4 TSF until the RTSF is commissioned with a depositional rate of 2.4Mtpm and final perspective capacity of 800Mt. Sound Mining has reviewed the design for the RTSF prepared by FWGR’s specialists and has concluded that the detailed design report provides a solid basis for the future development of a safe RTSF. The capital provision for all of the necessary infrastructure requirements has been reviewed and is considered appropriate. The capital expenditure estimates for the expansion of DP2 and the RTSF were undertaken and are currently presented at a PFS level of accuracy. The operational expenditure has been estimated from actual data at the current operations. These estimates are considered appropriate and in-line with industry standards. The QP, while cognizant of the risks identified in Item 12.1, remains satisfied that Mineral Resources and Mineral Reserves of FWGR are not likely to change materially as a consequence of these uncertainties. 23. RECOMMENDATIONS Item 23 The QPs recommend that FWGR continues to proactively seek the necessary regulatory approvals for the RTSF timeously to ensure that forecast production can continue uninterrupted.

Table 35: Glossary and Abbreviations Term Explanation Archaean Geological eon from 2,500Ma - 4,000Ma Assay The chemical analysis of ore samples to determine their metal content Auriferous Containing, or producing, gold Basin A geological basin is a large low-lying area, often below sea level Clastic A rock or sediment composed principally of transported broken fragments derived from pre-existing rocks or minerals Conformable A sequence of beds is said to be conformable when they represent an unbroken period of deposition Conglomerate A coarse-grained clastic sedimentary rock composed of rounded to subangular fragments set in a fine-grained matrix Craton An old and stable section of the continental lithosphere which has survived cycles of merging and rifting continents. Cratons are today generally found in the interior of tectonic plates Cut-off grade The lowest grade of mineralized rock that determines as to whether or not it is economic to recover its gold content by further concentration Density Measure of the relative “heaviness” of objects with a constant volume, density = mass/volume Deposit Any sort of earth material that has accumulated through the action of wind, water, ice or other agents De-survey Mathematical reconstruction in 3D space of a borehole trace using azimuth and dip survey data Detrital Formed from eroded loose rock and mineral material Dilution Waste or material below the cut-off grade that contaminates the ore during the course of mining operations and thereby reduces the average grade mined Definitive Feasibility Study (DFS) A definitive engineering estimate of all costs, revenues, equipment requirements and production at a -5% to +10% level of accuracy.

Far West Gold Recoveries (Proprietary) Limited Document No: PR/SMI/1330/23 120 Term Explanation Dolomite Carbonate mineral, CaMg(CO3)2. The word dolomite is also used to describe the sedimentary carbonate rock, which is composed predominantly of the mineral dolomite Doré An unrefined, therefore impure, alloy of gold with variable quantities of silver and smaller quantities of base metals, which is produced at a mine before passing on to a refinery for upgrading to London Good Delivery standard, which usually consists of 85% gold on average Drillhole Exploration hole drilled for the purposes of exploring for and evaluating sub-surface geology, in this instance the presence and distribution of gold Dyke A tabular vertical or near-vertical body of igneous rock formed by magmatic injection into planar zones of weakness such as faults or fractures that is discordant to the bedding or foliation of the country rock Estimation The quantitative judgement of a variable Exploration Prospecting, sampling, mapping, drilling and other work involved in the search for mineralization Facies The sum total of sedimentary features that characterize a sediment as having been deposited in a given environment; an assemblage of metamorphic rocks which are considered to have formed under similar conditions of temperature and pressure Fault A fracture in earth materials, along which the opposite sides have been displaced parallel to then plane of the movement Fire Assay The assaying of metallic ores by methods requiring the use of furnace heat Fluvial Produced by the action of a stream or river Footwall The underlying side of a stope or ore body Goldfield An auriferous deposit defined in a geographically distinct sub-basin Granite An intrusive felsic rock which is granular in texture Hydrothermal The circulation of hot water. Hydrothermal circulation occurs most often in the vicinity of sources of heat within the Earth's crust. In general, this occurs near volcanic activity Indicated Mineral Resource Is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated Mineral Resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated Mineral Resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated Mineral Resource may only be converted to a probable Mineral Reserve. Inferred Mineral Resource Is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred Mineral Resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred Mineral Resource has the lowest level of geological confidence of all Mineral Resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred Mineral Resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a Mineral Reserve. Karoo A large semi-desert natural region of South Africa which lends its name to the geological Karoo Supergroup which is often used as an age description for the eon from 145Ma - 360Ma Kriging An interpolation method that minimizes the estimation error in the determination of a mineral resource. Kriging is a method of interpolation for which the interpolated values are modelled by a Gaussian process governed by prior covariances License, Permit, Lease or other similar entitlement Any form of license, permit, lease or other entitlement granted by the relevant Government department in accordance with its mining legislation that confers on the holder certain rights to explore for and/or extract minerals that might be contained in the land, or ownership title that may prove ownership of the minerals Life-of-Mine (LoM) Number of years in the current mine plan that an operation will extract and treat ore Measured Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured Mineral Resource is sufficient to allow a qualified person to apply modifying factors, in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a measured Mineral Resource has a higher level of confidence than the level of confidence of either an indicated Mineral Resource or an inferred Mineral Resource, a measured Mineral Resource may be converted to a proven Mineral Reserve or to a probable Mineral Reserve. Mineable That portion of a mineral resource for which extraction is technically and economically feasible Mineral Asset(s) Any right to explore and/or mine which has been granted (“property”), or entity holding such property or the securities of such an entity, including but not limited to all corporeal and incorporeal property, mineral rights, mining titles, mining leases, intellectual property, personal property (including plant equipment and infrastructure), mining and exploration tenures and titles or any other right held or acquired in connection with the finding and removing of minerals and petroleum located in, on or near the Earth’s crust. Mineral Assets can be classified as Dormant Properties, Exploration Properties, Development Properties, Mining Properties or Defunct Properties Mineral Reserve Is an estimate of tonnage and grade or quality of indicated and measured Mineral Resources that, in the opinion of the QP, can be the basis of an economically viable project. More specifically, the economically mineable part of a measured or indicated Mineral Resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. The determination that part of a measured or indicated Mineral Resource is economically mineable must be based on a preliminary feasibility or feasibility study conducted by a QP applying the
Far West Gold Recoveries (Proprietary) Limited Document No: PR/SMI/1330/23 121 Term Explanation modifying factors to indicated or measured Mineral Resources. The study must demonstrate that, at the time of the reporting, extraction of the Mineral Reserve is economically viable under reasonable investment and market assumptions. The study must establish a life of mine plan that is technically achievable and economically viable, which will be the basis of determining the Mineral Reserve. And the term “economically viable” means that the QP has determined, using a discounted cashflow analysis, or has otherwise analytically determined that the extraction of the mineral reserve is economically viable under reasonable investment and market assumptions. Mineral Resource Is a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A Mineral Resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled. Modifying Factors Are the factors that a qualified person must apply to indicated and measured Mineral Resources and then evaluate in order to establish the economic viability of Mineral Reserves.
