EXPLANATORY NOTE



On June 15, 2023, Metals Acquisition Limited,
a private limited company incorporated under the laws of Jersey, Channel Islands (“New MAC,” “MAC Limited” or
the “Company”), consummated the previously announced Business Combination pursuant to 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, as supplemented by the CMPL Share
Sale Agreement Side Letter, dated as of April 21, 2023, as supplemented by the CMPL Share Sale Agreement Side Letter, dated May 31, 2023,
and as further supplemented by the CMPL Share Sale Agreement Side Letter, dated June 2, 2023 (as may be amended, supplemented, or otherwise
modified from time to time, the “Share Sale Agreement”) by and among the Company, Metals Acquisition Corp, a Cayman Island
exempted company (“MAC”), Metals Acquisition Corp. (Australia) Pty Ltd, an Australian private company and wholly-owned
subsidiary of MAC (“MAC-Sub”) and Glencore Operations Australia Pty Limited (“Glencore”). Capitalized
terms used and not otherwise defined in this Shell Company Report on Form 20-F (the “Report”) have the
respective meanings given to those terms in the Proxy Statement/Prospectus (the “Proxy Statement/Prospectus”), forming part
of the Registration Statement on Form F-4 of the Company, as amended (File No.333-269007) (the “Registration
Statement”).



Pursuant to the Share Sale Agreement, MAC-Sub
acquired from Glencore 100% of the issued share capital of Cobar Management Pty. Limited, an Australian private company (“CMPL”),
which owns and operates the Cornish, Scottish and Australian underground copper mine (the “CSA Mine”) near Cobar, New South
Wales, Australia. Immediately prior to the Business Combination, MAC merged with and into MAC Limited (the “Merger”), with
New MAC continuing as the surviving company (MAC Limited following the Merger is referred to as New MAC) and CMPL becoming an indirect
subsidiary of New MAC following the Business Combination.



As part of the Merger: (i) each issued and outstanding
MAC Class A Ordinary Share and MAC Class B Ordinary Share was converted into one ordinary share, par value $0.0001 per share, of New MAC
(“New MAC Ordinary Shares”) and (ii) each issued and outstanding whole warrant to purchase MAC Class A Ordinary Shares was
converted into one New MAC Warrant at an exercise price of $11.50 per share (“New MAC Warrants”), subject to the same terms
and conditions existing prior to such conversion.



In connection with the execution and delivery
of the Share Sale Agreement, MAC entered into Subscription Agreements (the “Subscription Agreements”) with certain investors
(the “PIPE Investors”), pursuant to which the PIPE Investors agreed to subscribe for and purchase, and MAC agreed to issue
and sell to the PIPE Investors an aggregate of 22,951,747 New MAC Ordinary Shares at a price of $10.00 per share, for aggregate gross
proceeds of $229,517,470 (the “PIPE Financing”). Four of the PIPE Investors are officers and directors of MAC and one of the
PIPE Investors is also an affiliate of Green Mountain Metals LLC (the “Sponsor”) and they have agreed to subscribe for 230,000
New MAC Ordinary Shares in the aggregate, at a purchase price of $10.00 per share, for aggregate gross proceeds of $2,300,000 all pursuant
to the Subscription Agreements on the same terms and conditions as all other PIPE Investors. Such subscribed shares were converted into
New MAC Ordinary Shares in connection with the Merger. New MAC has also agreed to grant certain customary registration rights to the PIPE
Investors in connection with the PIPE Financing.



In connection with the Subscription Agreements,
Green Mountain Metals, LLC, MAC’s sponsor, agreed to transfer an aggregate of 988,333 shares of Class B common stock of MAC that
it currently holds and agreed to sell 500,000 MAC Private Placement Warrants at a price of $1.50 for each MAC Private Placement Warrant
to certain investors who agreed to subscribe for a significant number of New MAC Ordinary Shares.



On June 12, 2023, MAC Limited and BEP Special
Situations VI LLC (“Bluescape”) entered into a director nomination side letter (the “Director Nomination Agreement”),
which provides that, for so long as Bluescape (together with its affiliates) holds at least 1.25 million of New MAC Ordinary Shares, Bluescape
will at its sole discretion be entitled to (but not obliged to) designate one (1) director to be nominated for appointment to the board
of directors of New MAC (such appointment to be in accordance with its articles of association). In the event Bluescape and its affiliates,
together, cease to hold at least 1.25 million of New MAC Ordinary Shares, Bluescape shall promptly cause the resignation of such director
and New MAC may promptly remove such director at its sole discretion. Any person appointed as a director in accordance with the Director
Nomination Agreement must not be prohibited from acting as a director of New MAC under any applicable law or the rules of any relevant
stock exchange and must be “independent” in accordance with the rules of any relevant stock exchange.

MAC-Sub (as borrower), MAC and MAC Limited (as
guarantors) and Sprott (as lender) entered into a Mezzanine Loan Note Facility Agreement dated March 10, 2023 pursuant to which Sprott
made available a US$135 million loan facility agreement available to MAC-Sub, for funding purposes in connection with the Business Combination
(the “Mezz Facility”). MAC-Sub is subject to standard and customary mandatory prepayment terms for a facility of this nature,
and the Mezz Facility is subject to substantially similar terms relating to conditions, representations and warranties, customary terms,
covenants, conditions precedent, events of default and other provisions as the syndicated facilities agreement (the “SFA”)
by and between MAC-Sub and several lenders. In connection with the Mezz Facility, New MAC, MAC, Sprott Private Resource Lending II (Collector),
LP (the “Equity Subscriber”) and Sprott Private Resource Lending II (Collector-2), LP, (the “Warrant Subscriber”),
entered into a subscription agreement (the “Sprott Subscription Agreement”) pursuant to which the Equity Subscriber committed
to purchase 1,500,000 New MAC Ordinary Shares (the “Subscribed Shares”) at a purchase price of $10.00 per share and an aggregate
purchase price of $15,000,000. In addition, in accordance with the terms of the Mezz Facility, the Warrant Subscriber received 3,187,500
warrants to purchase New MAC Ordinary Shares (the “New MAC Financing Warrants”) once the Mezz Facility began. Each New MAC
Financing Warrant entitles the holder to purchase one New MAC Ordinary Share. The New MAC Financing Warrant documentation contains customary
anti-dilution clauses.



Moreover, certain other related agreements have
been entered into in connection with the Business Combination, including the Royalty Deed, Offtake Agreement, Amended and Restated Registration
Rights Agreement, Senior Loan Facility Agreement, Mezzanine Debt Facility Agreements, Silver Purchase Agreement, Osisko Redemptions Backstop
Facility and Copper Stream, each as described in the Proxy Statement/Prospectus under the
headings “Summary of the Proxy Statement/Prospectus— Certain Agreements Related to the Business Combination”
and “Certain Agreements Related to the Business Combination,” which are incorporated herein by reference.



The Business Combination was consummated on June
15, 2023. The transaction was unanimously approved by MAC’s Board of Directors and was approved at the extraordinary general meeting
of MAC’s shareholders held on June 5, 2023. MAC’s shareholders also voted to approve all other proposals presented at the
extraordinary general meeting. On June 16, 2023, New MAC Ordinary Shares and New MAC Warrants commenced trading on the New York Stock
Exchange (the “NYSE”), under the symbols “MTAL” and “MTAL.WS,” respectively.



Certain amounts that appear in this Report may
not sum due to rounding.



Except as otherwise indicated or required by context,
references in this Report to “we,” “us,” “our,” “Company” or “New MAC” refer
to Metals Acquisition Limited, a private limited company incorporated under the laws of Jersey, Channel Islands.

| | ------- | -------------------------------------------------



| | A. | Major Shareholders
| | -- | ------------------



The following table sets forth information regarding
the beneficial ownership of New MAC Ordinary Shares as of the date hereof by:



| | · | each person known by us to be the beneficial owner of more than 5% of New MAC Ordinary Shares;
| | - | ----------------------------------------------------------------------------------------------



| | · | each of our directors and executive officers; and
| | - | -------------------------------------------------



| | · | all of our directors and executive officers as a group.
| | - | -------------------------------------------------------



Beneficial ownership is determined according to
the rules of the SEC, which generally provide that a person has beneficial ownership of a security if that person possesses sole or shared
voting or investment power over that security. A person is also deemed to be a beneficial owner of securities that person has a right
to acquire within 60 days including, without limitation, through the exercise of any option, warrant or other right or the conversion
of any other security. Such securities, however, are deemed to be outstanding only for the purpose of computing the percentage beneficial
ownership of that person but are not deemed to be outstanding for the purpose of computing the percentage beneficial ownership of any
other person. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities.



As of the date hereof, there are 48,409,448 New
MAC Ordinary Shares issued and outstanding.



Unless otherwise indicated, we believe that all
persons named in the table below have sole voting and investment power with respect to all New MAC Ordinary Shares beneficially owned
by them.

| | (7) | Reflects (i) 5,640,362 New MAC Ordinary Shares and (ii) 6,128,695
New MAC Ordinary Shares underlying Private Placement Warrants exercisable within 60 days. The shares reported herein are beneficially
owned in the name of the Sponsor. There are three managers of the Sponsor’s board of managers, Michael (Mick) James McMullen, John
Rhett Miles Bennett, and Ashley Elizabeth Zumwalt-Forbes. Each manager has one vote, and the approval of two of the three members of
the board of managers is required to approve an action of the Sponsor. Under the so-called “rule of three,” if voting and
dispositive decisions regarding an entity’s securities are made by two or more individuals, and a voting and dispositive decision
requires the approval of a majority of those individuals, then none of the individuals is deemed a beneficial owner of the entity’s
securities. This is the situation with regard to the Sponsor. Based upon the foregoing analysis, no individual manager of the Sponsor
exercises voting or dispositive control over any of the securities beneficially owned by the Sponsor, even those in which he directly
holds a pecuniary interest. Accordingly, none of them will be deemed to have or share beneficial ownership of such shares.

| | ITEM 12. | DESCRIPTION OF SECURITIES OTHER THAN EQUITY SECURITIES
| | -------- | ------------------------------------------------------



Warrants



Public Warrants



Upon the completion of the Merger, there were
8,838,260 New MAC Warrants outstanding. The New MAC public warrants, which entitle the holder to purchase one New MAC Ordinary Share at
an exercise price of $11.50 per share, will become exercisable on July 15, 2023, which is 30 days after the completion of the Business
Combination. The New MAC public warrants will expire on June 15, 2028 (i.e., five years after the completion of the Business Combination)
or earlier upon redemption or liquidation in accordance with their terms.



Private Warrants



Following the completion of the Merger and upon
consummation of the Business Combination, there were also 6,128,695 New MAC private placement warrants held by the Sponsor and 63,550
private placement warrants held by Fourth Sail Discovery LLC and 436,450 warrants held by Fourth Sail Long Short LLC. The New MAC private
placement warrants are identical to the New MAC public warrants except that, so long as they are held by the Sponsor or its permitted
transferees, (i) they will not be redeemable by New MAC, (ii) they (including the New MAC Ordinary Shares issuable upon exercise
of these warrants) may not, subject to certain limited exceptions, be transferred, assigned or sold by the Sponsor until July 15, 2023,
which is 30 days after the completion of the Business Combination, and (iii) they may be exercised by the holders on a cashless
basis.



New MAC Financing Warrants



Under the Mezz Facility, Sprott received a pro
rata allocation of 3,187,500 warrants to purchase New MAC Ordinary Shares (the “New MAC Financing Warrants”). Each New MAC
Financing Warrant entitles the holder to purchase one New MAC Ordinary Share. The New MAC Financing Warrant documentation will contain
customary anti-dilution clauses. The New MAC Financing Warrants will be fully transferrable and will last for the full five-year term
of the Mezz Facility with an exercise price of US$12.50 per share. Upon exercise, New MAC may either (i) cash-settle the New MAC
Warrants, or (ii) direct the holder to off-set the exercise price against the outstanding principal amount of the facility. New MAC
may elect to accelerate the exercise date for the New MAC Financing Warrants if New MAC Ordinary Shares are quoted on a recognized stock
exchange as over two (2) times the exercise price for twenty (20) consecutive trading days.
