Ladies and Gentlemen: 

We have acted as United States counsel to Metals Acquisition Corp, a Cayman Islands exempted company (the “Company”), in connection with the preparation and filing with the U.S. Securities and Exchange Commission (the “Commission”), pursuant to the Securities Act of 1933, as amended (the “Securities Act”), of the Registration Statement on Form S-1 of the Company (as amended through the date hereof, the “Registration Statement”), including a related prospectus filed with the Registration Statement (the “Prospectus”) relating to the proposed underwritten public offering of up to 28,750,000 units of the Company (the “Units”) (which includes up to 3,750,000 Units that may be issued and sold pursuant to the exercise of an over-allotment option described in the Registration Statement), with each Unit consisting of:

(i)       one Class A ordinary share of the Company, par value $0.0001 per share (“Ordinary Shares,” and the Ordinary Shares underlying the Units, the “Shares”); and

(ii)       one-third of one redeemable warrant of the Company (each whole warrant, a “Warrant”), with each Warrant entitling the holder to purchase one Ordinary Share, to be issued under a Warrant Agreement (the “Warrant Agreement”) to be entered into by the Company and Continental Stock Transfer & Trust Company, as warrant agent (in such capacity, the “Warrant Agent”);

pursuant to the terms of an underwriting agreement (the “Underwriting Agreement”) to be executed by the Company and Citigroup Global Markets Inc., as representative of the underwriters named therein (the “Underwriters”).

This opinion letter is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

In connection with this opinion letter, we have examined and relied upon the Registration Statement, the Prospectus, the form of Underwriting Agreement and the form of Warrant Agreement, and the originals or copies certified to our satisfaction of such records, documents, certificates, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinions expressed below. In addition to the foregoing, we have made such investigations of law as we have deemed necessary or appropriate as a basis for the opinions set forth herein.
