Proven Operational & Financial Performance Rational decision to halt production rather than to operate at a loss Namib Minerals has adopted significant strategic measures for risk mitigation MM and RM are strongly positioned to thrive in many go - forward operating and mining environments Redwing & Mazowe were placed on Care & Maintenance after 2018 Suboptimal Efficiency Concern • Smaller operating capacity results in reduced operating leverage. • Difficulty to sustain profits leading to financial loss. Capital Investment to Expand Capacity and Create Operating Leverage ■ Substantial CapEx investment can unlock significant cost reductions and create an efficient operating environment at scale. ■ Upon completion of successful financing, plans to purchase high - capacity machinery aimed to lower operational costs. (1) Namib Minerals does not possess a Special Mining Lease (“SML”). Monetary Policy • Change in monetary policy resulted in the effective gold price being reduced to 2/3rd of the spot price, making mining uneconomical. Zimbabwe Currency Crisis • The currency crisis further inhibited mining operations due to poor economic conditions, especially affecting precious metals mining. • Late payments for mined gold further impacted costs and operations. Special Mining Lease (SML) (1) ■ SML allows for the direct export of gold from Zimbabwe, denominated in USD. ■ The lease allows for significant monetary risk mitigation by enabling gold exports at spot rates.

Investor Presentation | 21 Non - IFRS Reconciliation Non - IFRS Measures Namib Minerals utilizes non - IFRS financial measures, including Adjusted EBITDA, C 1 cost per ounce, and AISC per ounce, to complement its IFRS reporting and provide stakeholders with a deeper understanding of its operational performance and financial health . These measures offer insights into trends and factors that IFRS metrics may not fully capture, and Namib Minerals believes they are essential for formulating strategic decisions and business plans . Non - IFRS financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with IFRS, and non - IFRS financial measures as used by Namib Minerals may not be comparable to similarly titled amounts used by other companies . While not a substitute for IFRS results, they exclude items not indicative of Namib Minerals’ core operations, enhancing comparability across periods . Adjusted EBITDA Namib Minerals defines Adjusted EBITDA as profit for the period before finance cost, (loss) gain on sale, related party credit loss, taxes, depreciation and amortization, impairment of long - lived assets, interest income and financial guarantee remeasurement. The table below presents Greenstone’s Adjusted EBITDA, reconciled to its Profit for the period, which is the most comparable IFRS measure, for the year ended December 31, 2023 and the year ended December 31, 2024: Greenstone Year ended December 31, 2024 Year ended December 31, 2023 (In thousands) 3,627 3,588 $ $ Profit for the period 2,415 1,522 Finance cost 41 - Disposal of investment 6,818 1,426 Related party credit loss 5,254 10,907 Income tax expense 2,705 4,141 Depreciation and amortization - 5,724 Impairment (114) (14) Interest income (486) (2,746) Financial guarantee remeasurement 20,260 24,548 $ $ Adjusted EBITDA How Mine C1 Cost Per Ounce Namib Minerals defines C1 cost as the sum of IFRS production costs and royalties expense. C1 cost per ounce is calculated as the C1 cost divided by the ounces of gold sold. Namib Minerals defines AISC as the sum of C1 cost, sustaining capital expenditure consisting of additions to property, plant and equipment, administrative expenditure, and silver by - product credit. AISC per ounce is calculated as the AISC divided by the ounces of gold sold. Namib Minerals uses this metric to measure the cost of extracting an ounce of gold and measure the efficiency of its mining operations. The table below presents How Mine’s AISC per ounce, reconciled to its Production cost, which is the most comparable IFRS measure, for the periods indicated. 36,501 38,648 $ $ Production cost (IFRS) 3,153 4,279 Royalties 39,654 42,927 $ C1 cost 33,585 37,239 Gold sales (oz) 1,181 1,153 $ C1 cost per ounce ($/oz) How Mine AISC Per Ounce How Mine Year ended December 31, 2024 Year ended December 31, 2023 ($ in thousands) 2023 How Mine Year ended December 31, 2024 Year ended December 31, ($ in thousands, unless otherwise indicated) 36,501 38,648 $ $ Production cost (IFRS) 3,153 4,279 Royalties 39,654 42,927 $ C1 cost 6,481 8,394 Sustaining capital expenditure 1,029 1,387 Administrative expenditures (32) (64) Silver by product credit 47,162 52,644 $ AISC 33,585 37,239 Gold sales (oz) 1,403 1,414 $ AISC per ounce ($/oz)

Namib Minerals Risk Factors Investor Presentation | 22 Risks Related to Namib Minerals’ Business, Operations and Industry                  Greenstone entered into a share purchase agreement (the “SPA”) on June 17, 2024 pursuant to which it purchased the parent company (“BMC”) that holds the Mazowe, Redwing, and How Mines from Metallon Corporation Limited ("Metallon"), a U.K. company currently undergoing insolvency proceeding overseen by a U.K. administrator. Under the SPA, certain former Greenstone shareholders (the “Guarantors”) are obligated to pay certain cash sums to Metallon, which to date have not been paid, and are obligated to indemnify Metallon, the U.K. administrator, and Greenstone for any claims brought against them in connection with the SPA, including for failure to pay such cash sums. Notwithstanding the nonpayment of the cash payment, Greenstone is the registered owner of all of the shares of BMC. However, Greenstone’s purchase of the Mazowe Mine, the Redwing Mine, and the How Mine may be subject to potential claims that may have a material adverse effect on Namib Minerals’ assets and operations. We are subject to risks related to the development of existing and new mining projects that may adversely affect our results of operations and profitability. We require significant additional capital to fund our business, including to restart the Mazowe and Redwing Mines, and no assurance can be given that such capital will be available at all or available on terms acceptable to us. Our Mineral Resource and Mineral Reserve estimates may be materially different from mineral quantities we may ultimately recover, our life - of - mine estimates may prove inaccurate and changes in operating and capital costs may render mineral resources uneconomic to mine. Our ability to replenish Mineral Reserves is subject to uncertainty and risks inherent in exploration, pre - feasibility and feasibility studies, and other project evaluation activities as well as competition within the industry for exploration, development, and operational projects. Mining is inherently hazardous and the related risks of disruptions to our mining operations may adversely impact the environment, the health, safety or security of our workers or the local community, production, cash flows and overall profitability. Theft of the mineral concentrate, final metals and production inputs may occur. These activities are difficult to control, can disrupt our business and can expose us to liability. Our assets and operations are subject to political, economic and other uncertainties as a result of being located in Zimbabwe and the DRC. Investor perceptions of risks in developing countries or emerging markets, including in Zimbabwe and the DRC, could reduce investor appetite for investments in Namib Minerals’ securities. Fluctuating foreign currency and exchange rates as well as Zimbabwean exchange controls may negatively impact our business, results of operations, and financial position. We have identified material weaknesses in our internal control over financial reporting. If we are unable to remediate these material weaknesses, identify additional material weaknesses in the future, or otherwise fail to implement and maintain an effective system of internal controls, we may be unable to accurately or timely report our results of operations or prevent fraud, and investor confidence and the market price of our securities may be materially and adversely affected. The price of gold is subject to volatility and may have a significant effect on our future activities and profitability. We cannot guarantee that there will not be an increase in input costs affecting our results of operations and financial performance. Our operations are vulnerable to infrastructure constraints, including power and water supply. Mining operations and projects are vulnerable to supply chain disruptions such that operations and development projects could be adversely affected. We derive all of our revenues from the sale of gold to one company which is controlled by the Zimbabwean authorities. Our rights to mine in Zimbabwe are derived from three mining leases, and the loss of our rights under any of these mining               leases would have a material adverse effect on our financial condition and results of operations.  Acquisitions, strategic partnerships, joint ventures and other partnerships may not perform in accordance with expectations, may fail to receive required regulatory approvals or may disrupt our operations and adversely affect our credit ratings and profitability. We may be unable to identify acquisition opportunities and successfully execute and close acquisitions, which could limit our potential for growth. The mining industry is highly competitive and there is no guarantee we will always be able to compete effectively. We may not be able to comply with the financial covenants related to our current or future bank borrowings or arrangements. We depend on key personnel for the success of our business. Most of our employees are members of the Associated Mine Workers Union of Zimbabwe and any work stoppage or industrial action implemented by the union may affect our business, results of operations and financial performance. We were required to facilitate the economic participation of certain indigenous groups in our business and may be subject to outstanding and remaining liabilities and claims as a result. We are subject to labor and employment laws and regulations, which could increase our costs and restrict our operations in the future. Our business, financial condition, and results of operations may be adversely affected by the occurrence of an outbreak of infectious diseases, a pandemic or other public health threats, and natural disasters. Our management of workplace health and safety matters may expose our business to significant risk. Our operations are underpinned by numerous contractual arrangements with third parties and non - compliance with these arrangements may substantially affect our operations or profits. Our insurance coverage may not be sufficient in all possible contexts, and we may not be able to rely upon our insurance in certain circumstances. If our operations do not perform as expected, we may be required to write down the carrying value of our investments, which could affect any future profitability and our ability to pay dividends. Since operations at our Mazowe and Redwing mines were halted in 2018 and 2019, respectively, we have been subject to litigation regarding disputed debts and corporate rescue proceedings pursuant to Zimbabwean insolvency laws. Lawsuits may be filed against us and an adverse ruling in any such lawsuit could have a material adverse effect on our business, results of operations and financial performance.

Risks Related to Cybersecurity  Security breaches, loss of data and other disruptions could compromise sensitive information related to our business and prevent us from accessing critical information or expose us to liability.  Cybersecurity breaches and other disruptions or failures in our information technology systems could compromise our information, result in the unauthorized disclosure of confidential supplier, employee, and company information, damage our reputation, and expose us to liability. Risks Related to Laws and Regulations Investor Presentation | 23        Our operations are subject to various government approvals, permits, licenses and legal regulation for which no assurance can be provided that such approvals, permits or licenses will be obtained or if obtained will not be revoked or suspended. Failure to comply with the U.S. Foreign Corrupt Practices Act and similar laws in Zimbabwe and elsewhere associated with our activities could subject us to penalties and other adverse consequences. Existing and future environmental laws may increase our costs of doing business, result in significant liabilities, fines or penalties, and may restrict our operations. We are subject to complex laws and regulations, which could have a material adverse effect on our operations and financial results. Existing and future laws and regulations governing issues involving climate change, and public sentiment regarding climate change, could result in increased operating costs or otherwise impact our operations. Namib Minerals may be subject to Zimbabwean capital gains tax as a result of its recently completed business combination and Greenstone’s acquisition of the holding company of our mining assets. There is general market uncertainty as a result of the conflicts in Ukraine and Israel - Gaza. Risks Related to the Ownership of Namib Minerals’ Securities and Other General Matters        Future sales and issuances of our ordinary shares (“Ordinary Shares”) could result in additional dilution of the percentage ownership of our shareholder and could cause our share price to fall. Future sales of a substantial number of shares of our Ordinary Shares, or the perception in the market that the holders of a large number of Ordinary Shares intend to sell shares, could reduce the market price of our Ordinary Shares. We will incur increased costs as a result of operating as a public company, and our management will devote substantial time to new compliance initiatives. Our management has limited experience in operating a Nasdaq - listed public company. There can be no assurance that we will be able to comply with the continued listing standards of Nasdaq. One shareholder owns the majority of our issued and outstanding Ordinary Shares and has the right to appoint a majority of the members of our board of directors and its interests may conflict with those of our other shareholders, which may have the effect of delaying or preventing a change in control. We are a “controlled company” under Nasdaq rules and able to rely on exemptions from certain corporate governance requirements that could adversely affect our shareholders.               We may redeem our unexpired warrants (“Warrants”) prior to their exercise at a time that is disadvantageous to you, thereby making your warrants worthless. The Warrant Agreement relating to our Warrants designates the courts of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by holders of our Warrants, which could limit the ability of warrant holders to obtain a favorable judicial forum for disputes with our company. We do not intend to pay cash dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of our Ordinary Shares. We are a holding company. Our only significant asset is our ownership of 100% of the securities of Greenstone, and we will accordingly be dependent on distributions from Greenstone and its subsidiaries to meet our financial obligations and to pay dividends, if any. Our Second Amended and Restated Memorandum and Articles of Association contain certain provisions, including anti - takeover provisions, that limit the ability of shareholders to take certain actions and could delay or discourage takeover attempts that shareholders may consider favorable. Our limited history makes it difficult to evaluate our business and prospects and may increase the risks associated with your investment. If an active market for our securities develops and continues, the trading price of our securities could be volatile and subject to wide fluctuations in response to various factors, some of which are beyond our control. If securities or industry analysts do not publish or cease publishing research or reports about us, our business, or our market, or if they change their recommendations regarding our Ordinary Shares adversely, then the price and trading volume of our Ordinary Shares could decline. We may not be able to timely and effectively implement internal controls and procedures required by Section 404 of the Sarbanes - Oxley Act. We are an “emerging growth company” within the meaning of the Securities Act and the Exchange Act, and as we may take advantage of certain exemptions from disclosure requirements available to emerging growth companies, our securities may be less attractive to investors and more difficult to compare our performance to the performance of other public companies. As a foreign private issuer, we are exempt from a number of U.S. securities laws and rules promulgated thereunder and will be permitted to publicly disclose less information than U.S. public companies must. This may limit the information available to holders of our Ordinary Shares. We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses. This would subject us to U.S. GAAP reporting requirements which may be difficult to comply with. Your ability to protect your rights through U.S. courts may be limited as we are incorporated under the law of the Cayman Islands. We conduct substantially all of our operations, and half of our directors and executive officers reside, outside of the United States. You may face difficulties in protecting your interests because we are incorporated under Cayman Islands law. Namib Minerals Risk Factors

The assumptions and estimates underlying such financial forecast information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties. See also “Forward - Looking Statements” on Slide 2. Actual results may differ materially from the results contemplated by the financial forecast information contained in this Presentation and the inclusion of such information in this Presentation should not be regarded as a representation by any person that the results reflected in such forecasts will be achieved. Namib Minerals does not intend to or undertake any obligation to update or otherwise revise the projected financial information to reflect circumstances existing after the date when made or to reflect the occurrence of future events in the event that any or all of the assumptions underlying the projected financial information are no longer valid. Accordingly, they should not be viewed as "guidance" of any sort. Financial Information; Non - IFRS Financial Terms Certain company financial information and data contained this Presentation is unaudited and does not conform to requirements promulgated by the SEC (including Regulation S - X). Accordingly, such information and data may not be included in, may be adjusted in, or maybe presented differently in, any report or document to be filed or furnished by Namib Minerals with the SEC. Furthermore, some of the financial information and data contained in this Presentation, such as all - in sustaining costs (“AISC”) per ounce, C1 Cost per ounce, and Adjusted EBITDA, have not been prepared in accordance with International Financial Reporting Standards (“IFRS”). Definitions of such non - IFRS measures are included on Slide 26 of this Presentation. An investor should not consider these items in isolation or as alternatives to cost of sales, production cost, or any other measure of financial performance presented in accordance with IFRS or as an indicator of Namib Minerals’ performance. Namib Minerals believe these non - IFRS measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to its financial condition and results of operations. Namib Minerals’ management uses these non - IFRS measures for trend analyses and for budgeting and planning purposes. Namib Minerals believes that the use of these non - IFRS financial measures provides an additional tool for investors to use in evaluating projected operating results and trends in and in comparing Namib Minerals’ financial measures with other similar companies, many of which present similar non - IFRS financial measures to investors. Management of Namib Minerals does not consider these non - IFRS measures in isolation or as an alternative to financial measures determined in accordance with IFRS. The principal limitation of these non - IFRS financial measures is that they exclude significant expenses and income that are required by IFRS to be recorded in Namib Minerals’ financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management about which expense and income are excluded or included in determining these non - IFRS financial measures. You should not rely on any single financial measure to evaluate Namib Minerals’ business. A reconciliation of non - IFRS financial measures used in this Presentation to the most directly comparable IFRS financial measures is included on slide 21 with respect to historical financial information. Cautionary Note Regarding Mineral Resources and Mineral Reserves Estimates of "measured", "indicated" and "inferred" mineral resources as well as "proven" and "probable" mineral reserves shown in this Presentation are defined in Subpart 1300 of Regulation S - K promulgated by the SEC ("S - K 1300"). Please see Slide 31 for more information. The estimation of measured resources and indicated resources involves greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable mineral reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. Investors are cautioned not to assume that any or all of the mineral resources are economically or legally mineable or that these mineral resources will ever be converted into mineral reserves. You are cautioned that mineral resources do not have demonstrated economic viability.

Definitions Investor Presentation | 25 Mineral Resources • A Mineral Resource is a concentration or occurrence of solid 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 eventual economic extraction. The location, quantity, grade, continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling. • An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated based on limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An Inferred Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of an Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration. • An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation. • A Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of modifying factors to support detailed mine planning and final evaluation of the economic viability of the deposit. Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation. A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated or an Inferred Mineral Resource. It may be converted to either a Proven Mineral Reserve or a Probable Mineral Reserve. Mineral Reserves • A Mineral Reserve is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at prefeasibility or feasibility level as appropriate that include application of modifying factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified. The reference point at which Mineral Reserves are defined, usually the point where the ore is delivered to the processing plant, must be stated. It is important that in all situations where the reference point is different, such as for a saleable product, a clarifying statement is included to ensure that the reader is fully informed as to what is being reported. • A Probable Mineral Reserve is the economically mineable part of an Indicated, and in some circumstances, a Measured Mineral Resource. The confidence in the modifying factors applying to a Probable Mineral Reserve is lower than that applying to a Proven Mineral Reserve. • A Proven Mineral Reserve is the economically mineable part of a Measured Mineral Resource. A Proven Mineral Reserve implies a high degree of confidence in the modifying factors. Feasibility Studies • A prefeasibility study is a comprehensive study of a range of options for the technical and economic viability of a mineral project that has advanced to a stage where a preferred mining method, in the case of underground mining, or the pit configuration, in the case of an open - pit, is established and an effective method of mineral processing is determined. It includes a financial analysis based on reasonable assumptions on the modifying factors and the evaluation of any other relevant factors which are sufficient for a competent person, acting reasonably, to determine if all or part of the Mineral Resource may be converted to a Mineral Reserve at the time of reporting. A prefeasibility study is at a lower confidence level than a feasibility study. • A feasibility study is a comprehensive technical and economic study of the selected development option for a mineral project that includes appropriately detailed assessments of applicable modifying factors together with any other relevant operational factors and detailed financial analysis that are necessary to demonstrate at the time of reporting that extraction is reasonably justified (economically mineable). The results of the study may reasonably serve as the basis for a final decision by a proponent or financial institution to proceed with, or finance, the development of the project. The confidence level of the study will be higher than that of a prefeasibility study.

Cautionary Note Regarding Mineral Resources

Estimates of “measured”, “indicated” and “inferred” mineral resources as well as “proven” and “probable” mineral reserves shown in this communication are defined in Subpart 1300 of Regulation S-K promulgated by the SEC (“S-K 1300”). The estimation of measured resources and indicated resources involves greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable mineral reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. Investors are cautioned not to assume that any or all of the mineral resources are economically or legally mineable or that these mineral resources will ever be converted into mineral reserves. You are cautioned that mineral resources do not have demonstrated economic viability.
