Cautionary Note Regarding Forward Looking Statements

This press release contains forward-looking information within the meaning of Canadian securities laws ("forward-looking statements"). Forward-looking statements are typically identified by words such as "believe," "expect," "anticipate," "intend," "estimate," "plans," "postulate," and similar expressions, or are those which, by their nature, refer to future events. All statements that are not statements of historical fact are forward-looking statements, including, but not limited to, statements regarding management's beliefs, plans, estimates, and intentions; the Transaction and the ability to complete it and other transactions contemplated by the arrangement agreement; the timing and satisfaction of conditions to consummation of the Transaction; the receipt of required regulatory approvals; the possibility of termination of the arrangement agreement; and the expected benefits to Alta Copper and its securityholders. These forward-looking statements are made as of the date of this press release and, although Alta Copper believes such statements are reasonable, there can be no assurance that expectations and assumptions will prove to be correct. Forward-looking statements are not guarantees of future results or performance and are subject to risks, uncertainties, assumptions, and other factors that could cause actual results or outcomes to differ materially from those expressed or implied, including, but not limited to: the possibility that the Transaction will not be completed on the terms or timing currently contemplated, or at all; failure to obtain or satisfy required regulatory approvals (including matters in relation to the Investment Canada Act) and other closing conditions; the negative impact of a failed Transaction on the price of Alta Copper shares or the Company's business; Nascent's failure to pay the consideration at closing; failure to realize expected benefits of the Transaction; restrictions imposed on Alta Copper while the Transaction is pending; significant transaction costs or unknown liabilities; diversion of management's attention from ongoing business operations; and other risks and uncertainties affecting Alta Copper, including those relating to permitting, capital expenditures, exploration and development activity, and the future price and demand for gold, copper, and other metals. Accordingly, readers should not place undue reliance on forward-looking statements. Alta Copper disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law.
