Forward Looking Statements

This Current Report includes, or incorporates by reference, forward-looking statements. All statements other than statements of historical facts contained in this Current Report are forward-looking statements. Any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are also forward-looking statements. In some cases, you can identify forward-looking statements by words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “expect,” “anticipate,” “believe,” “seek,” “strategy,” “future,” “opportunity,” “may,” “target,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” “preliminary,” or similar expressions that predict or indicate future events or trends or that are not statements of historical matters, but the absence of these words does not mean that a statement is not forward-looking. 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, growth and capital investments, operational and cost performance, future market conditions, or economic performance and developments in the capital and credit markets and expected future financial performance, the restart of Greenstone’s Mazowe mine and 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 Congo (the “DRC”), mineral reserve and resource estimates, production, and other operating results, productivity improvements, expected net proceeds, including from any PIPE investment, expected additional funding, the percentage of redemptions of SPAC’s public stockholders, growth prospects and outlook of PubCo’s operations, individually or in the aggregate, including the achievement of project milestones, commencement and completion of commercial operations of certain of Greenstone’s 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 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 and speak only as of the date of such statement. 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 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 SPAC will not seek, or otherwise fails, to extend its business combination deadline as necessary for the Business Combination to be completed; (iii) the failure to satisfy the conditions to the consummation of the Business Combination, including the adoption of the Business Combination Agreement by the stockholders of SPAC and Greenstone 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 Business Combination on Greenstone’s business relationships, performance, and business generally; (vii) the outcome of any legal proceedings that may be instituted against Greenstone, PubCo or SPAC related to the Business Combination Agreement or the Business Combination; (viii) failure to realize the anticipated benefits of the Business Combination; (ix) the inability to meet listing requirements and maintain the listing of PubCo’s securities on the Nasdaq; (x) the inability to remediate the identified material weaknesses in Greenstone’s internal control over financial reporting, which, if not corrected, could adversely affect the reliability of Greenstone’s and PubCo’s financial reporting; (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 PubCo 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 Business Combination, identify and realize additional opportunities, and manage 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 PubCo will be unable to raise additional capital to execute its business plan, which may 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; (xvii) the risk that any additional financing in connection with the Business Combination may not be raised on favorable terms or at all; (xviii) potential volatile and sporadic trading of SPAC’s securities; and (xix) the continuation of trading of SPAC’s units, shares of Class A common stock and warrants on the OTC Markets, including whether an active public market for SPAC’s units, shares of Class A common stock and warrants will be sustained on this market in the future. The foregoing list is not exhaustive, and there may be additional risks that neither SPAC nor Greenstone presently know or that SPAC and Greenstone currently believe are immaterial. You should carefully consider the foregoing factors, any other factors discussed in this Current Report 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, 2024, which was filed with the SEC on March 31, 2025, the risks described in the Registration Statement, which includes the Proxy Statement, and those discussed and identified in filings made with the SEC by SPAC and PubCo, from time to time. PubCo, 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 Current Report speak only as of the date of this Current Report. None of SPAC, Greenstone 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 SPAC, Greenstone 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 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.

No Offer or Solicitation

This Current Report shall not constitute an offer to sell or exchange, the solicitation of an offer to buy or a recommendation to purchase, any securities, or a solicitation of any vote, consent or approval, nor shall there be any sale, issuance or transfer of securities in any jurisdiction in which such offer, solicitation or sale may be unlawful under the laws of such jurisdiction. No offering of securities in the Business Combination shall be made except by means of a prospectus meeting the requirements of the Securities Act or an exemption therefrom.
