1246773 B.C. Ltd. and 2311548 Alberta Ltd. Announce Closing of $4.1 Million Concurrent Private Placement

In Connection with the Proposed Business Combination to Form [b]Atacama Copper Corporation[/b]

Toronto, May 11, 2021 - 1246773 B.C. Ltd. ("773") and 2311548 Alberta Ltd. ("TargetCo") are pleased to announce that further to the companies' news releases dated March 12, 2021, and March 29, 2021, TargetCo has successfully closed the previously-announced non-brokered private placement (the "Private Placement") of 8,223,156 subscription receipts (the "Subscription Receipts") at a price of $0.50 per Subscription Receipt for gross proceeds of $4,111,578. Each Subscription Receipt will entitle the holder thereof to receive, subject to adjustment in certain circumstances, one common share of TargetCo (a "TargetCo Share") in accordance with the terms and conditions of the Subscription Receipts.

As further described in the news releases dated March 12, 2021 and March 29, 2021, 773 and TargetCo have entered into an amalgamation agreement whereby TargetCo shall amalgamate with a wholly-owned subsidiary of 773 (the "Amalgamation"). Immediately prior to the Amalgamation, the Subscription Receipts are expected to convert into TargetCo Shares which will subsequently be exchanged pursuant to the Amalgamation for shares of 773. The gross proceeds of the Private Placement have been deposited into escrow pending the satisfaction of certain escrow release conditions, including the completion of the Amalgamation. The escrow release conditions are in accordance with the subscription receipt agreement dated May 10, 2021, entered into among 773, TargetCo, and TSX Trust Company. For further details concerning the Amalgamation, please see the news release dated March 12, 2021.

The Private Placement has been completed in connection with the previously-announced series of transactions (collectively, the "Transactions") between 773 and TargetCo that will, among other things, result in 773 indirectly acquiring the rights to the El Cofre Project, the Los Naranjos Project, the Caballo Muerto Project and the Placeton Project located in Chile (the "Chile Properties"). The Transactions are conditional on the TSX Venture Exchange ("TSXV") approving the listing of the common shares of 773 (the "Resulting Issuer Shares"), and other customary conditions.

The net proceeds of the Private Placement will be used by TargetCo to advance exploration on the Placeton and El Cofre projects and for general corporate purposes following completion of the Amalgamation.

For further details relating to the Transactions and the Private Placement, please refer to 773's news releases dated March 12, 2021, and March 29, 2021.
