| **Item 1.01** | **Entry into a Material Definitive Agreement.** |

---

On March 31, 2023, Metals Acquisition Corp (the "Company") issued an unsecured non-convertible promissory note (the "Note") to Green Mountain Metals LLC (the "Sponsor") pursuant to which the Company may borrow up to $339,876.65 from the Sponsor for transaction costs reasonably related to the consummation of the Business Combination (as defined below). As previously disclosed, Michael James McMullen, the Company's Chief Executive Officer, is the Manager of the Sponsor.

The Note bears no interest and all unpaid principal under the Note will be due and payable in full up the earlier of (i) August 2, 2023 and (ii) the acquisition of the Cornish, Scottish and Australian Mine ("CSA Mine") in the Company's business combination (the "Business Combination"). The issuance of the Note was made in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended.

The foregoing description of the Note does not purport to be complete and is qualified in its entirety by reference to the full text of the Note, a copy of which is filed herewith as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference herein.

| **Item 2.03** | **Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.** |

---

The information set forth above in Item 1.01 of this Current Report on Form 8-K is incorporated by reference herein.

**<u>IMPORTANT ADDITIONAL INFORMATION AND WHERE TO FIND IT</u>**

For additional information on the proposed Business Combination, see the relevant materials that MAC has filed with the Securities and Exchange Commission (the "SEC"), including a registration statement on Form F-4, which includes a proxy statement/prospectus of MAC. MAC's shareholders and other interested persons are advised to read the preliminary proxy statement/prospectus and the amendments thereto and, when available, the definitive proxy statement/prospectus and documents incorporated by reference therein filed or to be filed with the SEC in connection with the proposed Business Combination, as these materials will contain important information about the CSA Mine, MAC, New MAC and the proposed Business Combination. After the Form F-4 is declared effective by the SEC, MAC will mail the definitive proxy statement/prospectus and other relevant materials to shareholders of MAC as of a record date to be established for voting on, among other things, the proposed Business Combination. Shareholders will also be able to obtain copies of the preliminary proxy statement/prospectus, the definitive proxy statement/prospectus, and other documents filed with the SEC that will be incorporated by reference therein, without charge, once available, at the SEC's website at www.sec.gov. The information contained on, or that may be accessed through, the websites referenced in this communication is not incorporated by reference into, and is not a part of, this communication.

**<u>FORWARD-LOOKING STATEMENTS</u>**

This Current Report on Form 8-K includes "forward-looking statements." MAC's actual results may differ from expectations, estimates, and projections and, consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as "expect," "estimate," "project," "budget," "forecast," "anticipate," "intend," "plan," "may," "will," "could," "should," "believes," "predicts," "potential," "continue," and similar expressions (or the negative versions of such words or expressions) are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, MAC's expectations with respect to future performance of the CSA Mine and anticipated financial impacts and other effects of the proposed business combination, the satisfaction of the closing conditions to the proposed transaction and the timing of the completion of the proposed transaction. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from those discussed in the forward-looking statements. Most of these factors are outside MAC's control and are difficult to predict. Factors that may cause such differences include, but are not limited to: the occurrence of any event, change, or other circumstances that could give rise to the termination of the Share Sale Agreement; the outcome of any legal proceedings that may be instituted against MAC following the announcement of the Share Sale Agreement dated as of March 17, 2022 (as amended by the Deed of Consent and Covenant dated as of November 22, 2022 (the "Share Sale Agreement"); the inability to complete the proposed transaction, including due to failure to obtain financing, approval of the shareholders of MAC, certain regulatory approvals, or satisfy other conditions to closing in the Share Sale Agreement; the occurrence of any event, change, or other circumstance that could give rise to the termination of the Share Sale Agreement, or could otherwise cause the transaction to fail to close MAC's inability to secure the expecting financing for the consideration under the Share Sale Agreement; the inability to obtain or maintain the listing of MAC's shares following the proposed transaction; the risk that the proposed transaction disrupts current plans and operations as a result of the announcement and consummation of the proposed business combination; the ability to recognize the anticipated benefits of the proposed business combination, which may be affected by, among other things; the supply and demand for copper; the future price of copper; the timing and amount of estimated future production, costs of production, capital expenditures and requirements for additional capital; cash flow provided by operating activities; unanticipated reclamation expenses; claims and limitations on insurance coverage; the uncertainty in mineral resource estimates; the uncertainty in geological, metallurgical and geotechnical studies and opinions; infrastructure risks; and dependence on key management personnel and executive officers; and other risks and uncertainties indicated from time to time in the final prospectus of MAC for its initial public offering and the preliminary and definitive proxy statements relating to the proposed business combination that MAC intends to file with the SEC, including those under "Risk Factors" therein, and in MAC's other filings with the SEC. MAC cautions that the foregoing list of factors is not exclusive. MAC cautions readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. MAC does not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions, or circumstances on which any such statement is based.

More information on potential factors that could affect MAC's or CSA Mine's financial results is included from time to time in MAC's public reports filed with the SEC, including its Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K as well as the preliminary and the definitive proxy statements MAC intends to file with the SEC in connection with MAC's solicitation of proxies for the meeting of stockholders to be held to approve, among other things, the proposed business combination. If any of these risks materialize or MAC's assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that MAC does not presently know, or that MAC currently believes are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect MAC's expectations, plans or forecasts of future events and views as of the date of this communication. MAC anticipates that subsequent events and developments will cause its assessments to change. However, while MAC may elect to update these forward-looking statements at some point in the future, MAC specifically disclaims any obligation to do so, except as required by law. These forward-looking statements should not be relied upon as representing MAC's assessment as of any date subsequent to the date of this communication. Accordingly, undue reliance should not be placed upon the forward-looking statements.

**<u>NO OFFER OR SOLICITATION</u>**

This Current Report on Form 8-K shall not constitute a solicitation of a proxy, consent or authorization with respect to any securities or in respect of the proposed business combination. This Current Report on Form 8-K shall also not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any states or jurisdictions in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended, or an exemption therefrom.

Any outstanding principal amount to date under this Note may be prepaid at any time by the Maker, at its election and without penalty; *provided*, *however*, that Payee shall have a right to first convert such principal balance pursuant to <u>Section 6</u> below upon notice of such prepayment. Under no circumstances shall any individual, including but not limited to any officer, director, employee or shareholder of the Maker, be obligated personally for any obligations or liabilities of the Maker hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. **Interest**. No interest shall accrue on the unpaid principal balance of this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Involuntary Bankruptcy, Etc</u>. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of Maker or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. **Remedies**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Upon the occurrence of an Event of Default specified in Section 5(a) hereof, Payee may, by written notice to Maker, declare this Note to be due immediately and payable, whereupon the unpaid principal amount of this Note, and all other amounts payable thereunder, shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived, anything contained herein or in the documents evidencing the same to the contrary notwithstanding.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Upon the occurrence of an Event of Default specified in Sections 5(b) and 5(c), the unpaid principal balance of this Note, and all other sums payable with regard to this Note, shall automatically and immediately become due and payable, in all cases without any action on the part of Payee.

Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand, notice of dishonor, protest, and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by Payee under the terms of this Note, and all benefits that might accrue to Maker by virtue of any present or future laws exempting any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing for any stay of execution, exemption from civil process, or extension of time for payment; and Maker agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order desired by Payee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. **Unconditional Liability**. Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by Payee, and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted by Payee with respect to the payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to Maker or affecting Maker's liability hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. **Notices**. All notices, statements or other documents which are required or contemplated by this Agreement shall be: (i) in writing and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing, (ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party and (iii) by electronic mail, to the electronic mail address most recently provided to such party or such other electronic mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if delivered personally, on the business day following receipt of written confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after mailing if sent by mail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. **Construction**. THIS NOTE SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS THEREOF.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. **Severability**. Any provision contained in this Note which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. **Trust Waiver**. Reference is made to the final prospectus of the Maker, dated as of July 28, 2021 and filed with the U.S. Securities and Exchange Commission ("***SEC***") (File No. 333-257854) on July 30, 2021 (the "***Prospectus***"). Payee represents and warrants that it has received the Prospectus and understands that the Maker has established a trust account (the "***Trust Account***") containing the proceeds of its initial public offering (the "**IPO**") and the over-allotment shares acquired by its underwriters and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of the Maker's public shareholders (including over-allotment shares acquired by the Maker's underwriters, the "***Public Shareholders***"), and that, except as otherwise described in the Prospectus, the Maker may disburse monies from the Trust Account only: (a) to the Public Shareholders in the event they elect to redeem their shares of the Maker in connection with the consummation of the Maker's initial Business Combination (as such term is used in the Prospectus) or in connection with an extension of its deadline to consummate a Business Combination, (b) to the Public Shareholders if the Maker fails to consummate a Business Combination within twenty-four (24) months after the closing of the IPO, subject to extension by amendment to the Maker's organizational documents, (c) with respect to any interest earned on the amounts held in the Trust Account, as necessary to pay any taxes or (d) to the Maker after or concurrently with the consummation of a Business Combination. For and in consideration of the Maker entering into this agreement and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Payee hereby agrees on behalf of itself and its affiliates that, notwithstanding anything to the contrary in this agreement, that neither Payee nor any of its affiliates do now or shall at any time hereafter have any right, title, interest or claim of any kind in or to any monies in the Trust Account or distributions therefrom, or make any claim against the Trust Account (including any distributions therefrom), regardless of whether such claim arises as a result of, in connection with or relating in any way to, this agreement or any proposed or actual business relationship between the Maker or its Representatives, on the one hand, and Payee or its Representatives, on the other hand, or any other matter, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (collectively, the "***Released Claims***"). Payee on behalf of itself and its affiliates hereby irrevocably waive any Released Claims that it or any of its affiliates may have against the Trust Account (including any distributions therefrom) now or in the future as a result of, or arising out of, any negotiations, contracts or agreements with the Maker or its Representatives and will not seek recourse against the Trust Account (including any distributions therefrom) for any reason whatsoever (including for an alleged breach of any agreement with the Maker or its affiliates). Payee agrees and acknowledges that such irrevocable waiver is material to this agreement and specifically relied upon by the Maker and its affiliates to induce the Maker to enter into this agreement, and Payee further intends and understands such waiver to be valid, binding and enforceable against Payee and each of its affiliates under applicable law. To the extent Payee or any of its affiliates commence any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to the Maker or its Representatives, which proceeding seeks, in whole or in part, monetary relief against the Maker or its Representatives, Payee hereby acknowledges and agrees that Payee and its affiliates' sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit Payee or its affiliates (or any person claiming on any of their behalves or in lieu of any of them) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. **Amendment; Waiver**. Any amendment hereto or waiver of any provision hereof may be made with, and only with, the written consent of the Maker and the Payee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. **Assignment**. No assignment or transfer of this Note or any rights or obligations hereunder may be made by any party hereto (by operation of law or otherwise) without the prior written consent of the other party hereto and any attempted assignment without the required consent shall be void.
