Mr. Pierre Lassonde, an investor, reports

PIERRE LASSONDE FILES EARLY WARNING REPORT

This press release is being disseminated as required by securities legislation in connection with the filing of an early warning report regarding the common shares of Atacama Copper Corp. (the issuer) held by Firelight Holdings Ltd. (the company), a company wholly owned by Pierre Lassonde.

The requirement to file the early warning report was triggered on Feb. 9, 2024, as a result of the closing of the business combination of the issuer with TCP1 Corp. Pursuant to the terms of the business combination, TCP1 became a wholly owned subsidiary of the issuer, and each former shareholder of TCP1 received 64.815 common shares in the capital of the issuer in exchange for each common share of TCP1 that they held at a deemed price of $70 per TCP1 common share. Following the completion of the transaction, the 103,100 common shares in the capital of TCP1 that were previously held by the company were exchanged for 6,682,426 common shares in the capital of the issuer, along with the six-for-one share consolidation of 2,777,800 subscription receipts into 462,966 common shares in the capital of the issuer, representing an aggregate of 7,145,392 shares, or approximately 11.66 per cent of the common shares of the issuer on a non-diluted basis and approximately 10.53 per cent of the common shares of the issuer on a fully diluted basis.

The common shares received by the company pursuant to the transaction will continue to be held by the company for investment purposes. The company does not currently intend to acquire or dispose of any additional securities of the issuer. Nonetheless, the company may, depending on price, market conditions, or other conditions or factors it considers relevant from time to time, increase or decrease its beneficial ownership, control or direction over common shares or other securities of the issuer through market transactions, private agreements or otherwise.

An early warning report in connection with this press release is being filed by the company in accordance with applicable Canadian securities laws and will be available on SEDAR+.
