Industry and Market Data Industry and market data used in this Presentation have been obtained from third - party industry publications and sources as well as from research reports prepared for other purposes. Although all such information has been obtained from sources believed to be reliable and are included in good faith, MAC has not independently verified the data obtained from these sources and cannot assure you of the data’s accuracy or completeness. Accordingly, no representation is made as to the reasonableness of the assumptions made within or the accuracy or completeness of such data. Recipients are cautioned not to place undue weight on such information. Forward Looking Statements This Presentation 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 words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “would,” and similar expressions (or the negative versions of such words or expressions) are intended to identify such forward - looking statements. These forward - looking statements may include, for example, statements about our ability to complete the Business Combination, or, if we do not consummate the Business Combination, any other initial business combination, amidst the uncertainty resulting from the ongoing COVID - 19 pandemic, and the effect of the ongoing pandemic on the economy and any business or businesses with which we consummate our initial business combination; the benefits of the Business Combination; the future financial performance of MAC Acquisition Limited (“New Mac”) following the Business Combination; expansion plans and opportunities; our public securities’ potential liquidity and trading; the lack of a market for our securities; the inability of the parties to successfully or timely consummate the Business Combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect New MAC or the expected benefits of the Business Combination; the Trust Account not being subject to claims of third parties; and our financial performance following the Business Combination. 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: satisfaction of conditions to the Business Combination; adverse variances in the actual resources, reserves and life of mine inventories at CMPL from those contained in the Technical Report; adverse operating conditions and geotechnical risks applicable to CMPL’s operations; CMPL’s substantial capital expenditure requirements; CMPL’s inability to effectively manage growth; the occurrence of any event, change or other circumstances that could give rise to the termination of the Share Sale Agreement; the ability to obtain and/or maintain the listing of the New MAC Ordinary Shares and public warrants on the NYSE following the Business Combination; our and CMPL’s success in retaining or recruiting, or changes required in, our officers, key employees or directors following the Business Combination; our officers and directors allocating their time to other businesses and potentially having conflicts of interest with our business or in approving the Business Combination; the risks associated with cyclical demand for CMPL’s products and vulnerability to industry downturns and regional, national or global downturns; fluctuations in CMPL’s revenue and operating results; fluctuations and volatility in commodity prices and foreign exchange rates; unfavorable conditions or further disruptions in the capital and credit markets and CMPL’s or New MAC’s ability to obtain additional capital on commercially reasonable terms; competition from existing and new competitors; CMPL’s ability to integrate any businesses it acquires; CMPL’s dependence on third - party contractors to provide various services; compliance with and liabilities related to environmental, health and safety laws, regulations and other regulations, including those related to climate change, including changes to such laws, regulations and other requirements; climate change; changes in U.S., Australian or other foreign tax laws; the amount of redemptions made by public shareholders; increases in costs, disruption of supply, or shortages of materials; general economic or political conditions; and other risks and uncertainties indicated from time to time in the proxy statement/prospectus of MAC for its initial public offering, 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’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 proxy statement/prospectus New MAC and MAC filed 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. 2 Disclaimer

Non - GAAP Financial Measures This Presentation includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, EBITDA, Free Cash Flow, C1 Cash Costs, All - in Sustaining Costs and certain ratios and other metrics derived therefrom. These non - GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing CSA’s financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that CSA’s presentation of these measures may not be comparable to similarly - titled measures used by other companies. MAC believes these non - GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to CSA’s financial condition and results of operations. MAC believes that the use of these non - GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing CSA’s financial measures with other similar companies, many of which present similar non - GAAP financial measures to investors. These non - GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non - GAAP financial measures. Please refer to footnotes where presented on each page of this Presentation or to the appendix found at the end of this Presentation for a reconciliation of these measures to what CSA believes are the most directly comparable measure evaluated in accordance with GAAP. This Presentation also includes certain projections of non - GAAP financial measures. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, MAC is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward - looking non - GAAP financial measures is included. For the same reasons, MAC is unable to address the probable significance of the unavailable information, which could be material to future results. Use of Projections This Presentation contains certain forecasts, including, without limitation, projected operational metrics. CSA’s independent auditors have not studied, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, no independent auditor has expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this Presentation. These projections are for illustrative purposes only and should not be relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the prospective financial and operational information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial and operational information. Projections are inherently uncertain due to a number of factors outside of MAC’s and CSA’s control. While all projections, estimates and targets are necessarily speculative, MAC believes that the preparation of prospective information involves increasingly higher levels of uncertainty the further out the projection, estimate or target extends from the date of preparation. Accordingly, there can be no assurance that the prospective results are indicative of future performance or that actual results will not differ materially from those presented in the prospective financial and operational information. Inclusion of the prospective financial and operational information in this Presentation should not be regarded as a representation by any person that the results contained in the prospective financial and operational information will be achieved.

Risk Factors 28 Risk Factors Summary Certain factors may have a material adverse effect on our business, financial condition, results of operations and reputation. You should carefully consider the following risk factors that apply to the business and operations of the CSA copper mine (“CSA Mine” or “CMPL”) and to the potential acquisition by Metals Acquisition Corp (the “Business Combination”). The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. If any of these risks actually occurs, alone or in combination with other events or circumstances, our business, financial condition, results of operations, future prospects and reputation, as well as our ability to realize the anticipated benefits of the Business Combination, could be materially and adversely affected. In that event, the trading price of our ordinary shares following the Business Combination could decline, and you could lose part or all of your investment. In this section, “Target” means the CSA copper mine, the “SPAC” means Metals Acquisition Corp, and the “Company,” “we,” “our” or “us” means Target (together with its consolidated subsidiaries) and MAC, collectively, for periods prior to the Business Combination and shall refer to New MAC (as defined below) and its consolidated subsidiaries for periods from and after the Business Combination. Immediately prior to the Business Combination, MAC will be merged with and into MAC Acquisition Limited (the “Merger”), with MAC Acquisition Limited continuing as the surviving company (MAC Acquisition Limited following the Merger is referred to as “New MAC”). The “Sponsor” means Green Mountain Metals LLC. These risk factors are provided to you in the context of your investment in the MAC’s ordinary shares, immediately prior to or concurrently with, and contingent upon, the consummation of the Business Combination of MAC and the Target, and are qualified in their entirety by the definitive documents and other disclosure documents. Risks Relating to CMPL’s Business and Industry • Estimates of reserves are uncertain and the volume and grade of ore actually recovered may vary from our estimates. • Our mining activities are subject to adverse operating conditions and geotechnical risks, which could adversely impact our ore recoveries and mining efficiencies. • To maintain our business, we will be required to make substantial capital expenditures. If we are unable to obtain needed capital or financing on satisfactory terms, it could have an adverse impact on our results of operations. • Our management of tailings are subject to significant environmental, health, safety and engineering challenges and risks, including the need to expand our tailings storage capacity that could adversely affect our business. • Interruption or other disruptions and delays to our operations could have a material adverse effect on our cash flow, results of operations and financial condition. • Our expected reduction in total direct site operating costs and increase in mined tonnages may not be realized in the short term or at all. • All production from the CSA Mine is sold to a single customer, GIAG, and such reliance on GIAG as a key customer may have significant consequences for CMPL’s cash flow and broader financial position. • Future project expansion and exploration success may not be achieved. • Maintenance of mining tenement title and approvals is essential to the ongoing conduct of our operations. • Land access to current or future mining tenements may not always be guaranteed. • The ongoing COVID - 19 pandemic could have an adverse effect on our business. • General labor market tightness in the mining sector may lead to higher costs than planned or the inability to secure the skilled workforce necessary to optimize the mine . • Severe weather events and natural disasters, such as storms and floods, may impact the ability of the CSA Mine to export its product in a timely manner and for us to otherwise conduct our operations. • Rehabilitation liabilities may increase or otherwise impact our operating margins. • Inability to access reliable transport and infrastructure could have an adverse impact on our revenue, productivity and reputation. • Equipment failure at the CSA Mine could have an adverse impact on our ability to continue operations.

Risk Factors (cont.) 29 Risks Relating to the CMPL's Business and Industry (cont.) • General cost inflation across Australia, including, but not limited to, energy prices may increase the costs of production more than anticipated. • Any new native title claims recognized over the mine site may impact the ability to operate or result in higher than planned costs. • Existing and future environmental laws and may increase our costs of doing business, result in significant liabilities, fines or penalties, and may restrict our operations. • We are subject to complex laws and regulations, which could have a material adverse effect on our operations and financial results. • Violations of anti - money laundering, sanctions and compliance laws may subject us to regulatory sanctions or other claims and could materially and adversely affect our business, financial condition and reputation. • The cost, outcome or impact of existing or future litigation could materially and adversely affect our business, financial condition and reputation. • Laws and regulations governing issues involving climate change, public sentiment regarding climate change, and the physical impacts of climate change could result in increased operating costs or otherwise impact our operations or products, which could have a material adverse effect on our business. • Our current and future operations require permits and licenses, and failure to comply with or obtain such permits and licenses could have a material impact on our business. • Any new tax legislation introduced by governments may change the current tax treatment, which could adversely impact our cash flow from the mine. • Premature mine closure or placement into care and maintenance could subject us to significant additional costs and could have a detrimental effect on our financial condition. • We may be subject to community opposition or negative publicity in connection with our activities as a major mining company. • We may be adversely affected by fluctuations in demand for, and prices of, copper. • Our operations are underpinned by numerous contractual arrangements with third parties and non - compliance with these arrangements may substantially affect our operations or profits. • Appreciation of the Australian dollar against the U.S. dollar could have the effect of increasing our mine’s cost of production, thus reducing our margins. • We depend on key personnel for the success of our business. • Our management of workplace health and safety matters may expose the company to significant risk. • Our insurance coverage may not be sufficient in all possible contexts and we may not be able to rely upon our insurance in certain circumstances. • Risks regarding international conflict and related market pressures may impact our business operations. • Information technology security breaches could harm our business activities and reputation. • Market risks and competition in the copper and battery metals industry in Australia may impact our business operations. • Sovereign risk and changes in law may impact our operations in unforeseen ways. • The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain executive management and qualified board members. Financial, Tax and Accounting - Related Risks • New MAC will be an “emerging growth company” and it cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make the post - combination company’s ordinary shares less attractive to investors and may make it more difficult to compare performance with other public companies. • Changes in accounting standards may have an adverse effect on the reported financial performance of our business. • Our balance sheet includes a number of assets that may be subject to impairment risk. • Application of existing tax laws, rules or regulations are subject to interpretation by taxing authorities. • Any new tax legislation introduced by governments may change the current tax treatment, which could adversely impact our cash flow from the mine.

Risk Factors (cont.) 30 Risks Relating to the SPAC and the Business Combination • There can be no assurance that the SPAC will be able to raise sufficient capital to consummate the Business Combination. • The SPAC's Sponsor, certain members of the SPAC's board of directors and its officers have interests in the Business Combination that may conflict with those of other shareholders in recommending that shareholders vote in favor of approval of the Business Combination and other proposals. • The SPAC’s Sponsor and certain of its directors and its officers hold all of the SPAC’s founder shares and private placement warrants. They will lose their entire investment with respect to such securities if we do not complete an initial business combination. • The Merger may be a taxable event for U.S. Holders of the SPAC’s securities. • New MAC may be or become a passive foreign investment company (or “PFIC”), which could result in adverse U.S. federal income tax consequences to U.S. Holders. • The U.S. federal income tax treatment of the redemption of the SPAC’s Class A Ordinary Shares depends on a shareholder’s specific facts. • Subsequent to the consummation of the Business Combination, New MAC may be required to take write - downs or write - offs, restructuring and impairment or other charges that could have a significant negative effect on its financial condition, results of operations and share price, which could cause you to lose some or all of your investment. • Existing shareholders will experience significant dilution as a result of the Business Combination, the PIPE financing and related transactions, and the market price of the SPAC’s Class A Ordinary Shares may be adversely affected. Future transactions contemplated by the definitive documentation for the Business Combination may also have a dilutive effect. • Beginning in January 2022, there has been a precipitous drop in the market values of growth - oriented companies. Accordingly, securities of growth companies such as ours may be more volatile than other securities and may involve special risks. • Securities of companies formed through SPAC mergers such as ours may experience a material decline in price relative to the share price of the SPAC prior to the merger. • If the SPAC’s shareholders fail to comply with the redemption requirements specified in the proxy statement/prospectus, they will not be entitled to redeem their Class A Ordinary Shares for a pro rata portion of the Trust Account. • New MAC may redeem your unexpired warrants prior to their exercise at a time that is disadvantageous to you, thereby making your warrants worthless. • Following the consummation of the Business Combination, New MAC will have no direct operations and no significant assets other than the ownership of CMPL. • New MAC will incur a significant amount of debt in connection with the Business Combination that is secured by substantially all of New MAC’s assets, and may in the future incur additional indebtedness, including in connection with the closing of the Business Combination. New MAC’s payment obligations under such indebtedness may limit the funds available to New MAC, and the terms of New MAC’s debt agreements may restrict its flexibility in operating its business. • Our warrant agreement designates the courts of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by holders of our warrants, which could limit the ability of warrant holders to obtain a favorable judicial forum for disputes with us. • We may amend the terms of the warrants in a manner that may be adverse to holders of public warrants with the approval by the holders of at least a majority of the then outstanding public warrants. In addition, we may amend the terms of our warrant agreement to allow for our warrants to be classified as equity in our financial statements with the approval by the holders of at least a majority of the public warrants and the private placement warrants, voting together as a single class. As a result, the exercise price of your warrants could be increased, the exercise period could be shortened and the number of our Class A Ordinary Shares purchasable upon exercise of a warrant could be decreased, all without your approval. • If you exercise your public warrants on a “cashless basis,” you will receive fewer of New MAC Ordinary Shares from such exercise than if you were to exercise such warrants for cash. • If the benefits of the Business Combination do not meet the expectations of investors or securities analysts, the market price of New MAC securities may decline. • The SPAC’s Sponsor and the SPAC’s directors, officers, advisors and their affiliates may elect to purchase public shares or public warrants from public shareholders, which may influence a vote on the proposed Business Combination and reduce the public “float” of its Class A Ordinary Shares. • The SPAC’s initial shareholders have agreed to vote in favor of the Business Combination, regardless of how the public shareholders vote.

Risk Factors (cont.) 31 Risks Relating to the SPAC and the Business Combination (cont.) • If the SPAC is unable to complete the Business Combination or any other business combination by August 2, 2023 (or such later date as the SPAC’s shareholders may approve), the SPAC will cease all operations except for the purpose of winding up, liquidating and dissolving. In such event, third parties may bring claims against the SPAC and, as a result, the proceeds held in the Trust Account could be reduced and the per share liquidation price received by shareholders could be less than $10.00 per share and the SPAC’s warrants will expire worthless. • The SPAC’s directors may decide not to enforce the indemnification obligations of the SPAC’s Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to its public shareholders. • If, before distributing the proceeds in the Trust Account to the SPAC’s public shareholders, the SPAC files a bankruptcy petition or an involuntary insolvency petition is filed against the SPAC that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of the SPAC’s shareholders and the per share amount that would otherwise be received by the SPAC’s shareholders in connection with its liquidation may be reduced . • If, after the SPAC distributes the proceeds in the Trust Account to its public shareholders, the SPAC files a bankruptcy petition or an involuntary insolvency petition is filed against the SPAC that is not dismissed, a bankruptcy or insolvency court may seek to recover such proceeds, and the SPAC and the SPAC’s Board may be exposed to claims of punitive damages. • The ability of shareholders to exercise redemption rights with respect to a large number of shares could increase the probability that the Business Combination would be unsuccessful and that shareholders would have to wait for liquidation to redeem their stock. • The unaudited pro forma condensed combined financial information included in the proxy statement/prospectus for the Business Combination may not be indicative of what the SPAC’s actual financial position or results of operations would have been. • The Business Combination is subject to conditions, including certain conditions that may not be satisfied on a timely basis, if at all. • There can be no assurance that the New MAC Ordinary Shares and warrants will be approved for listing on the NYSE following the Closing, or that New MAC will be able to comply with the listing standards of the NYSE. • Provisions in the Proposed Governing Documents may inhibit a takeover of New MAC, which could limit the price investors might be willing to pay in the future for New MAC Ordinary Shares and could entrench management. • You may not have the same benefits as an investor in an underwritten public offering. • Following the consummation of the Business Combination, New MAC will incur significant increased expenses and administrative burdens as a public company, which could have an adverse effect on its business, financial condition and results of operations. • The SPAC has identified a material weakness in its internal control over financial reporting. This material weakness could continue to adversely affect the SPAC’s ability to report its results of operations and financial condition accurately and in a timely manner. • New MAC’s failure to timely and effectively implement controls and procedures required by Section 404(a) of the SOX that will be applicable to it after the Business Combination is consummated could have a material adverse effect on its business. • Unlike many blank check companies, the SPAC does not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it easier for the SPAC to consummate the Business Combination even if a substantial majority of the SPAC’s shareholders do not agree. • If a shareholder or a “group” of shareholders are deemed to hold in excess of 15% of the issued and outstanding MAC Class A Ordinary Shares, such shareholder or group will lose the ability to redeem all such shares in excess of 15% of the issued and outstanding MAC Class A Ordinary Shares. • If, following the Business Combination, securities or industry analysts do not publish or cease publishing research or reports about New MAC, its business, or its market, or if they change their recommendations regarding New MAC’s securities adversely, the price and trading volume of New MAC’s securities could decline.

Risk Factors (cont.) 32 Risks Relating to New MAC’s Shares • There is no guarantee of a positive return on our New MAC’s shares. • There is no certainty that New MAC will pay dividends. • Because New MAC has no current plans to pay cash dividends on New MAC Ordinary Shares for the foreseeable future, you may not receive any return on investment unless you sell New MAC Ordinary Shares for a price greater than that which you paid for them. Risks Relating to Acquiring and Operating a Business in Non - U.S. Countries • Because CMPL’s operations are located outside of the Unites States, the SPAC may face additional burdens in connection with investigating, agreeing to and completing the Business Combination, and, if the Business Combination is consummated, New MAC may be subject to a variety of additional risks that may negatively impact its operations. • Existing and future government laws, regulations and other legal requirements that govern our business may increase our costs of doing business and may restrict our operations. • Any new tax legislation introduced by governments may change the current tax treatment, which could adversely impact our cash flow from the CSA Mine. Risks Relating to our Foreign Private Issuer Status • As a foreign private issuer, we are exempt from a number of rules under the U.S. securities laws and are permitted to file less information with the SEC than a U.S. company. This may limit the information available to holders of our Ordinary Shares. • We are a “foreign private issuer” within the meaning of the rules of the NYSE on which we intend to list our Ordinary Shares and, as a result, expect to qualify for, and intend to rely on, exemptions from certain corporate governance requirements. You will not have the same protections afforded to shareholders of companies that are subject to such requirements. • We may lose our foreign private issuer status in the future, which could result in significant additional cost and expense. • You may face difficulties in protecting your interests as a shareholder, as Jersey law provides substantially less protection when compared to the laws of the United States. • It may be difficult to enforce a U.S. judgment against us or our directors and officers outside the United States, or to assert U.S. securities law claims outside of the United States.
