Introductory Note

As previously disclosed, on June 17, 2024, Red Rock Acquisition Corporation, a Delaware corporation formerly known as Hennessy Capital Investment Corp. VI (the “Company”), Namib Minerals, an exempted company limited by shares incorporated under the laws of the Cayman Islands (“PubCo”), Midas SPAC Merger Sub Inc., a Delaware corporation and a direct wholly-owned subsidiary of PubCo (“SPAC Merger Sub”), Cayman Merger Sub Ltd., an exempted company limited by shares incorporated under the laws of the Cayman Islands and a direct wholly-owned subsidiary of PubCo (“Company Merger Sub”), and Greenstone Corporation, an exempted company limited by shares incorporated under the laws of the Cayman Islands (“Greenstone”), entered into a business combination agreement (as amended on December 6, 2024 and April 14, 2025, the “Business Combination Agreement”). Capitalized terms not otherwise defined herein have the same meanings ascribed to them in the Business Combination Agreement.

On May 6, 2025, the Company held a special meeting of its stockholders (the “Special Meeting”) during which the Company’s stockholders approved the proposal to approve the Business Combination (as defined below) and the other proposals related thereto. In connection with the Business Combination, holders of 3,168,984 shares of Class A common stock of the Company, par value $0.0001 per share (“SPAC Class A Common Stock”), exercised their right to redeem their shares for cash at a redemption price of approximately $10.89 per share, for an aggregate redemption amount of approximately $34.5 million.

On June 5, 2025 (the “Closing Date”), the parties to the Business Combination Agreement consummated (the “Closing”) the transactions contemplated by the Business Combination Agreement (the “Business Combination”), which resulted in, among other things: (i) Company Merger Sub merging with and into Greenstone (the “Company Merger”), with Greenstone being the surviving entity of the Company Merger and becoming a wholly-owned subsidiary of PubCo; (ii) immediately following the Company Merger, SPAC Merger Sub merging with and into the Company (the “SPAC Merger” and, together with the Company Merger, the “Mergers”), with the Company being the surviving entity of the SPAC Merger and becoming a wholly-owned subsidiary of PubCo; and (iii) at the effective time of the Mergers (a) each unit of the Company issued and outstanding immediately prior to the effective time of the SPAC Merger automatically was detached and the holder thereof was issued one share of SPAC Class A Common Stock and one-third of a warrant of the Company exercisable for one share of SPAC Class A Common Stock (each, a “SPAC Warrant”) in accordance with the terms of the Company’s unit, (b) each issued and outstanding share of common stock of the Company, par value $0.0001 per share, was cancelled in exchange for the right to receive one ordinary share of PubCo, par value $0.0001 per share (each, a “PubCo Ordinary Share”), (c) each outstanding SPAC Warrant became exercisable for one PubCo Ordinary Share on the same terms and conditions (each, a “PubCo Warrant”), and (d) the ordinary shares in the capital of Greenstone, par value $1.00 per share, that were issued and outstanding before Closing were exchanged for an aggregate of 48,869,960 newly issued PubCo Ordinary Shares and the right to receive up to 30.0 million PubCo Ordinary Shares upon the satisfaction of certain milestones.

The PubCo Ordinary Shares and PubCo Warrants are expected to commence trading on the Nasdaq Global Market and the Nasdaq Capital Market, respectively, under the symbols “NAMM” and “NAMMW,” respectively, on June 6, 2025.

The foregoing description of the Business Combination Agreement and Business Combination does not purport to be complete and is qualified in its entirety by reference to the full text of the Business Combination Agreement, which is filed as Exhibits 2.1, 2.2 and 2.3 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 1.01. Entry into a Material Definitive Agreement.

Registration Rights and Lock-up Agreement

On the Closing Date, PubCo, certain former stockholders of the Company (including the Sponsor) and certain former shareholders of Greenstone (such applicable former Company stockholders and Greenstone shareholders, collectively, the “Holders”) entered into a Registration Rights and Lock-up Agreement (the “Registration Rights and Lock-up Agreement”) pursuant to which, among other things, PubCo granted the Holders customary demand and piggyback registration rights. In addition, the Holders, other than one former shareholder of Greenstone, agreed not to transfer for a period of 12 months after the Closing Date any equity in PubCo acquired by such person in connection with the Business Combination (such equity, “Lock-up Shares”), subject to exceptions, provided that (x) 50% of the Lock-up Shares will be released on such date on which the last reported sale price of the PubCo Ordinary Shares equals or exceeds $12.50 per PubCo Ordinary Share (as adjusted for share splits, share combinations, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period commencing at least 150 days after the Closing Date; and (y) the other 50% of the Lock-up Shares will be released on the date on which the last reported sale price of the PubCo Ordinary Shares equals or exceeds $15.00 per PubCo Ordinary Share (as adjusted for share splits, share combinations, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period commencing at least 150 days after the Closing Date.

Pursuant to the Registration Rights and Lock-up Agreement, PubCo agreed to, within 15 business days after the Closing Date, file with the SEC (at PubCo’s sole cost and expense) a registration statement registering the resale of the registrable securities held by the Holders and to use its reasonable best efforts to have the registration statement declared effective as soon as practicable after the initial filing thereof, but in no event later than 10 calendar days after the SEC notifies PubCo that the SEC will not review the registration statement or that the registration statement will not be subject to further review and comment.

The foregoing description of the Registration Rights and Lock-Up Agreement and the rights and restrictions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the full text of the Registration Rights and Lock-Up Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The foregoing description of the Warrant Assumption Agreement and the rights and restrictions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the full text of the Warrant Assumption Agreement, a copy of which is filed as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 1.02. Termination of a Material Definitive Agreement.

On June 5, 2025, in connection with the Closing, the Company notified the Nasdaq Stock Market LLC (“Nasdaq”) that the Business Combination had become effective and requested that Nasdaq file a Notification of Removal from Listing and/or Registration under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on Form 25 to notify the SEC that the SPAC Class A Common Stock, SPAC Public Warrants and SPAC Units (collectively, the “SPAC Securities”) were to be delisted and deregistered under Section 12(b) of the Exchange Act. The deregistration will become effective 10 days from the filing of the Form 25. The Company intends to file with the SEC a Certification and Notice of Termination of Registration on Form 15 requesting the termination of registration of the SPAC Securities under Section 12(g) of the Exchange Act and the suspension of the Company’s reporting obligations under Sections 13 and 15(d) of the Exchange Act with respect to the SPAC Securities.
