Forward Looking Statements

This press release 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 “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions (or the negative versions of such words or expressions) are intended to identify such forward- looking statements. These forward-looking statements include, without limitation, MAC’s expectations with respect to future performance of the CSA Mine and anticipated financial impacts and other effects of the proposed business combination, the satisfaction of the closing conditions to the proposed transaction and the timing of the completion of the proposed transaction. 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 ability to recognize the anticipated benefits of the 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 definitive proxy statement/prospectus relating to the business combination that MAC filed with the SEC, 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 Mine’s financial results is included from time to time in MAC’s public reports filed with the SEC. 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.
