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 Transaction Agreement; the outcome of any legal proceedings that may be instituted against MAC following the announcement of the Transaction Agreement; the inability to complete the proposed transaction, including due to failure to obtain approval of the shareholders of MAC, certain regulatory approvals, or satisfy other conditions to closing in the Transaction Agreement; the occurrence of any event, change, or other circumstance that could give rise to the termination of the Transaction Agreement or could otherwise cause the transaction to fail to close MAC�s inability to secure the expecting financing for the consideration under the Transaction 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 proxy statement/prospectus relating to the proposed business combination, including those under �Risk Factors� therein, and in MAC�s other filings with the SEC. MAC caution that the foregoing list of factors is not exclusive. MAC caution readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. MAC do 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.

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.
