Item 1.01 Entry into a Material Definitive Agreement.

On January 9, 2023, Metals Acquisition Corp (the “Company”) issued an unsecured promissory note (the “Sponsor Convertible Note”) to Green Mountain Metals LLC (the “Sponsor”) pursuant to which the Company borrowed $300,000 from the Sponsor for transaction costs reasonably related to the consummation of the Business Combination (as defined below). All unpaid principal under the Sponsor Convertible Note will be due and payable in full on the earlier of (i) August 2, 2023 and (ii) the acquisition of the Cornish, Scottish and Australian Mine in the Company’s business combination (the “Business Combination”) (such earlier date, the “Maturity Date”). As previously disclosed, Michael James McMullen, the Company’s Chief Executive Officer, is the Manager of the Sponsor.

Pursuant to the terms of the Sponsor Convertible Note, the Sponsor will have the option, at any time on or prior to the Maturity Date, to convert any amounts outstanding under the Sponsor Convertible Note, up to $300,000 in the aggregate, into warrants to purchase the Company’s Class A ordinary shares, par value $0.0001 per share (“Class A ordinary shares”), at a conversion price of $1.50 per warrant, with each warrant entitling the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to the same adjustments applicable to the private placement warrants sold concurrently with the Company’s initial public offering.

Concurrently upon the issuance of the Sponsor Convertible Note, on January 9, 2023, the Sponsor exercised its option to convert the issued and outstanding loan amount of $300,000 under the Sponsor Convertible Note, resulting in the issuance of 200,000 private placement warrants to the Sponsor.
