Forward - looking statements include, without limitation, Greenstone’s, SPAC’s, PubCo’s, or their respective management teams’ expectations concerning the outlook for their or PubCo’s business, productivity, plans, and goals for future operational improvements and capital investments, operational performance, future market conditions, or economic performance and developments in the capital and credit markets and expected future financial performance, including the restart of the Mazowe Mine and the Redwing Mine and related expansion plans, capital expenditure plans and timeline, the development and goals of the prospective exploration licenses in the Democratic Republic of the Congo (the “DRC”), 2024 estimates of financial and operational performance, economic outlook for the gold mining industry, mineral reserve and resource estimates, outlook for investing in Zimbabwe, expectations regarding gold prices and exchange rates, production, total cash costs, all - in costs, cost savings and other operating results, productivity improvements, expected net proceeds, expected additional funding, the percentage of redemption of SPAC’s public stockholders, growth prospects and outlook of ’s operations, individually or in the aggregate, including the achievement of project milestones, commencement and completion of commercial operations of certain of Greenstone exploration and production projects, as well as any information concerning possible or assumed future results of operations of PubCo . Forward - looking statements also include statements regarding the expected benefits of the Proposed Business Combination . The forward - looking statements are based on the current expectations of the respective management teams of Greenstone and SPAC, as applicable, and are inherently subject to uncertainties and changes in circumstance and their potential effects . There can be no assurance that future developments will be those that have been anticipated . These forward - looking statements involve a number of risks, uncertainties or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward - looking statements . These risks and uncertainties include, but are not limited to, ( i ) the risk that the Proposed Business Combination may not be completed in a timely manner or at all, which may adversely affect the price of SPAC’s securities ; (ii) the risk that the Proposed Business Combination may not be completed by SPAC’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by SPAC ; (iii) the failure to satisfy the conditions to the consummation of the Proposed Business Combination, including the adoption of the Business Combination Agreement by the stockholders of SPAC and Greenstone, the satisfaction of the $ 25 million minimum cash amount following redemptions by SPAC’s public stockholders and the receipt of certain regulatory approvals ; (iv) market risks, including the price of gold ; (v) the occurrence of any event, change or other circumstance that could give rise to the termination of the Business Combination Agreement ; (vi) the effect of the announcement or pendency of the Proposed Business Combination on Greenstone’s business relationships, performance, and business generally ; (vii) risks that the Proposed Business Combination disrupts current plans of Greenstone and potential difficulties in its employee retention as a result of the Proposed Business Combination ; (viii) the outcome of any legal proceedings that may be instituted against Greenstone or SPAC related to the Business Combination Agreement or the Proposed Business Combination ; (ix) failure to realize the anticipated benefits of the Proposed Business Combination ; (x) the inability to maintain the listing of SPAC’s securities or to meet listing requirements and maintain the listing of PubCo’s securities on the Nasdaq ; (xi) the risk that the price of PubCo’s securities may be volatile due to a variety of factors, including changes in the highly competitive industries in which Greenstone plans to operate, variations in performance across competitors, changes in laws, regulations, technologies, natural disasters or health epidemics/pandemics, national security tensions, and macro - economic and social environments affecting its business, and changes in the combined capital structure ; (xii) the inability to implement business plans, forecasts, and other expectations after the completion of the Proposed Business Combination, identify and realize additional opportunities, and manage its growth and expanding operations ; (xiii) the risk that Greenstone may not be able to successfully develop its assets, including expanding the How mine, restarting and expanding its other mines in Zimbabwe or developing its exploration permits in the DRC ; (xiv) the risk that Greenstone will be unable to raise additional capital to execute its business plan, which many not be available on acceptable terms or at all ; (xv) political and social risks of operating in Zimbabwe and the DRC ; (xvi) the operational hazards and risks that Greenstone faces ; and (xvii) the risk that additional financing in connection with the Proposed Business Combination may not be raised on favorable terms, in a sufficient amount to satisfy the $ 25 million (post - redemptions) minimum cash amount condition to the Business Combination Agreement, or at all . The foregoing list is not exhaustive, and there may be additional risks that neither SPAC nor Greenstone presently know or that SPAC and Greenstone believe are immaterial . You should carefully consider the foregoing factors, any other factors discussed in this Presentation and the other risks and uncertainties described in the “Risk Factors” section of SPAC’s Annual Report on Form 10 - K for the year ended December 31 , 2023 , which was filed with the SEC on March 29 , 2024 , the risks to be described in the Registration Statement, and those discussed and identified in filings made with the SEC by SPAC and PubCo from time to time . Greenstone and SPAC caution you against placing undue reliance on forward - looking statements, which reflect current beliefs and are based on information currently available as of the date a forward - looking statement is made . Forward - looking statements set forth in this Presentation speak only as of the date of this Presentation . None of Greenstone, SPAC, or PubCo undertakes any obligation to revise forward - looking statements to reflect future events, changes in circumstances, or changes in beliefs . In the event that any forward - looking statement is updated, no inference should be made that Greenstone, SPAC, or PubCo will make additional updates with respect to that statement, related matters, or any other forward - looking statements . Any corrections or revisions and other important assumptions and factors that could cause actual results to differ materially from forward - looking statements, including discussions of significant risk factors, may appear, up to the consummation of the Proposed Business Combination, in SPAC’s or PubCo’s public filings with the SEC, which are or will be (as appropriate) accessible at www . sec . gov, and which you are advised to review carefully .

Disclaimer Continued 4 DISCLAIMER Use of Projections This Presentation contains projected financial information with respect to Greenstone . Such projected financial information constitutes forward - looking information, is for illustrative purposes only, and should not be relied upon as necessarily being indicative of future results . 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” above . 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 . None of the Company, SPAC or PubCo intends to or undertakes 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 proxy statement/prospectus or registration statement or other report or document to be filed or furnished by SPAC or PubCo with the SEC, including the Registration Statement . Furthermore, some of the financial information and data contained in this Presentation, such as all - in sustaining costs (“AISC”) per ounce, C 1 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 37 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 Greenstone’s performance . Greenstone, Namib Minerals and SPAC believe these non - IFRS measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Greenstone’s financial condition and results of operations . Greenstone’s management uses these non - IFRS measures for trend analyses and for budgeting and planning purposes . Greenstone, Namib Minerals and SPAC believe 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 Greenstone’s financial measures with other similar companies, many of which present similar non - IFRS financial measures to investors . Management of Greenstone 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 Greenstone’s 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 Greenstone’s business . A reconciliation of non - IFRS financial measures used in this Presentation to the most directly comparable IFRS financial measures is included on slide 37 with respect to historical financial information but is not included with respect to forecasted financial information, because, without unreasonable effort, Greenstone is unable to predict with reasonable certainty the amount or timing of non - IFRS adjustments that are used to calculate these Non - IFRS financial measures . 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 34 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 . Important Information for Investors and Shareholders In connection with the Proposed Business Combination, PubCo intends to file with the SEC the Registration Statement, which will include a prospectus with respect to PubCo’s securities to be issued in connection with the Proposed Business Combination and a proxy statement to be distributed to holders of SPAC’s common stock in connection with SPAC’s solicitation of proxies for the vote by SPAC’s stockholders with respect to the Proposed Business Combination and other matters to be described in the Registration Statement (the “Proxy Statement”) . After the SEC declares the Registration Statement effective, SPAC plans to file the definitive Proxy Statement with the SEC and to mail copies to stockholders of SPAC as of a record date to be established for voting on the Proposed Business Combination . This Presentation does not contain all the information that should be considered concerning the Proposed Business Combination and is not a substitute for the Registration Statement, Proxy Statement or for any other document that PubCo or SPAC may file with the SEC . Before making any investment or voting decision, investors and security holders of SPAC, PubCo and Greenstone are urged to read the Registration Statement and the Proxy Statement, and any amendments or supplements thereto, as well as all other relevant materials filed or that will be filed with the SEC in connection with the Proposed Business Combination as they become available because they will contain important information about, Greenstone, SPAC, PubCo and the Proposed Business Combination . Investors and security holders will be able to obtain free copies of the Registration Statement, the Proxy Statement and all other relevant documents filed or that will be filed with the SEC by PubCo and SPAC through the website maintained by the SEC at www . sec . gov .

Risk Factors 29

Namib Minerals Risk Factors 30 Risks Related to Greenstone  Greenstone entered into a share purchase agreement (the “SPA”) on June 17, 2024 pursuant to which it purchased the parent com pan y 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 Greens ton e 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 failur e t o pay such cash sums. Although the SPA has been consummated and is not conditioned on such payment or the satisfaction of such indemnification obli gat ions, Greenstone's purchase of the Mazowe Mine, the Redwing Mine, and the How Mine may be subject to potential claims if the Guarantors' fail to satisfy their indemnification obligations.  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 will require significant additional capital to fund our business, including to restart the Mazowe and Redwing Mines, and n o a ssurance 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 reco ver , 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 feasi bility studies, and other project evaluation activities as well as competition.  Mining is inherently hazardous and the related risks of disruptions to our mining operations may adversely impact our workers or the local community and our business.  Theft of the mineral concentrate, final metals and production inputs may occur. These activities are difficult to control, ca n d isrupt our business and can expose us to liability.  The assets and operations of Greenstone are subject to political, economic and other uncertainties as a result of being locat ed in Zimbabwe and the DRC.  Investor perceptions of risks in developing countries or emerging markets, including in Zimbabwe and the DRC, could reduce in ves tor appetite for investments Greenstone’s securities.  Fluctuating foreign currency and exchange rates as well as Zimbabwean exchange controls may negatively impact our business, r esu lts of operations, and financial position.  We have identified material weaknesses in our internal control over financial reporting. If we are unable to remediate these mat erial 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.  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 perfo rma nce.  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 lea ses 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 po tential 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 im plemented by the union may affect our business, results of operations and financial performance.  We are subject to labor and employment laws and regulations, which could increase our costs and restrict our operations in th e f uture.  Our business, financial condition, and results of operations may be adversely affected by the occurrence of an outbreak of in fec tious 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 arrangement s 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 c ert ain circumstances.  If our operations do not perform as expected, we may be required to write down the carrying value of our investments, which c oul d 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 litigati on 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 busine ss, 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 prev ent 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 informati on, 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  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 act ivities 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 pen alties, 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 re sul ts.  Existing and future laws and regulations governing issues involving climate change, and public sentiment regarding climate ch ang e, could result in increased operating costs or otherwise impact our operations.  PubCo and Greenstone may be subject to Zimbabwean capital gains tax as a result of the Business Combination and Greenstone’s acquis it ion of the holding company of our mining assets.  There is general market uncertainty as a result of the conflicts in Ukraine and Israel - Gaza.

Namib Minerals Risk Factors 31 Risks Related HCVI and the Business Combination  Hennessy Capital Investments Corp. VI (“HCVI” or “SPAC”) may not be able to consummate an initial business combination by Sep tem ber 30, 2024 (or as extended by amending its organizational documents), in which case it would cease all operations.  Hennessy Capital Partners VI LLC (the “Sponsor”), officers and directors of HCVI (the “SPAC Board”) have agreed to vote in fa vor of the Potential Business Combination, regardless of how SPAC’s public stockholders vote.  The Sponsor, certain members of the board of directors of the SPAC (the “SPAC Board”), certain officers of the SPAC, and cert ain anchor investors of the SPAC have interests in the Potential Business Combination that are different from or are in addition to public stockholders, which may include direct or indirect ownership of SPAC’s founder shares and/o r p rivate placement warrants, each of which will lose their value if a business combination is not consummated.  The Sponsor, officers and the SPAC Board has potential conflicts of interest in recommending that stockholders vote in favor of approval of the Potential Business Combination proposal and approval of the other proposals in connection therewith.  SPAC’s and Greenstone’s stockholders will experience dilution as a consequence of the Potential Business Combination.  Sponsor, the SPAC Board, officers, advisors and their affiliates may elect to purchase shares or warrants from public stockho lde rs of HCVI, which may influence the vote on the Potential Business Combination and reduce the public “float” of SPAC Class A Common Stock.  HCVI may waive one or more of the conditions to the Potential Business Combination.  There can be no assurance that the SPAC will be able to comply with the continued listing standards of Nasdaq. Risks Related to PubCo  PubCo will incur increased costs as a result of operating as a public company, and its management will devote substantial tim e t o new compliance initiatives.  PubCo’s management has limited experience in operating a Nasdaq - listed public company.  Uncertainties about the potential Business Combination prior to Closing may cause a loss of key personnel or cause key suppli ers or customers or other partners to delay or defer decisions concerning Greenstone or seek to change existing arrangements.  Following the Potential Business Combination, PubCo may be unable to obtain additional financing to fund its operations or gr owt h.  There can be no assurance that the PubCo Ordinary Shares that will be issued in connection with the potential Business Combin ati on or the PubCo Warrants will be approved for listing on the Nasdaq or, if approved, will continue to be so listed, or that PubCo will be able to comply with the continued listing standards.  PubCo will be a “controlled company” under the rules of Nasdaq and can rely on exemptions from certain corporate governance r equ irements that could adversely affect PubCo’s public shareholders.  Concentration of ownership after the potential Business Combination may have the effect of delaying or preventing a change in co ntrol.  PubCo may redeem unexpired warrants prior to their exercise at a time that is disadvantageous to holders, thereby making hold ers ’ warrants worthless.  The PubCo Warrant Agreement designates the courts of the State of New York or the United States District Court for the Southe rn 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 judi cia l forum for disputes with our company.  It is not expected that PubCo will pay dividends in the foreseeable future after the Business Combination.  Following the potential Business Combination, the only significant assets of PubCo will be ownership of the securities of Gre ens tone and HCVI, and PubCo does not currently intend to pay dividends and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of PubCo’s ordinary shares.  PubCo’s organizational documents to be adopted in connection with the Business Combination contain certain provisions, includ ing anti - takeover provisions, that limit the ability of shareholders to take certain actions and could delay or discourage takeover attempts.  PubCo has no operating or financial history and its results of operations may differ significantly from the unaudited pro for ma financial data included in this proxy statement.  PubCo may not be able to complete financing in connection with the Business Combination.  If the Business Combination’s benefits do not meet the expectations of investors or securities analysts, the market price of HCV I’s securities or, following the Closing, PubCo’s securities, may decline. A market for PubCo’s securities may not continue.  If, following the Business Combination, securities or industry analysts do not publish or cease publishing research or report s a bout PubCo, its business, or its market, or if they change their recommendations regarding the PubCo Ordinary Shares adversely, then the price and trading volume of the PubCo Ordinary Shares could decline.  If we fail to implement and maintain an effective system of internal controls, we may be unable to accurately or timely repor t o ur results of operations or prevent fraud, and investor confidence and the market price of our PubCo Ordinary Shares may be materially and adversely affected.  PubCo could be subject to securities class action litigation.  Subsequent to the Business Combination, PubCo may be required to take write - downs or write - offs, or PubCo may be subject to rest ructuring, impairment or other charges that could have a significant negative effect on PubCo’s financial condition, results of operations or the price of PubCo Ordinary Shares.  PubCo will qualify as an “emerging growth company” within the meaning of the Securities Act and the Exchange Act, and if it t ake s advantage of certain exemptions from disclosure requirements available to emerging growth companies, it could make PubCo’s securities less attractive to investors and may make it more difficult to compare PubCo’s pe rfo rmance to the performance of other public companies.

Appendix 32

RM & MM Care and Maintenance 33 Redwing & Mazowe were placed on Care & Maintenance after 2018 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 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 (please refer to slide 19) • Substantial CapEx investment can unlock significant cost reductions and create an efficient operating environment at scale. • Upon completion of successful financing, p lans to purchase high - capacity machinery aimed to lower operational costs. (1) Namib Minerals does not currently hold any 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.

Definitions 34 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 .

Non - IFRS Reconciliation 37 Non - IFRS Measures Greenstone 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 Greenstone 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 substitut e for, financial information presented in compliance with IFRS, and non - IFRS financial measures as used by Greenstone 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 Greenstone’s core operations, enhancing comparability across periods . Adjusted EBITDA Greenstone defines Adjusted EBITDA as profit for the year before finance cost, (loss) gain on sale, related party credit loss , t axes, depreciation, 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 year, which is the most comparable IF RS measure, for 2023: How Mine C1 Cost Per Ounce Greenstone 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. How Mine AISC Per Ounce Greenstone defines AISC as the sum of C 1 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 . Greenstone 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 .
