Vancouver, British Columbia--(Newsfile Corp. - February 1, 2024) - Atacama Copper Corporation (TSXV: ACOP) ("Atacama Copper" or the "Company") is pleased to announce that the Company has closed the third and final tranche of its previously announced brokered private placement (the "Financing") for an additional 1,666,667 subscription receipts of the Company ("Subscription Receipts") at a price of $0.18 per Subscription Receipt for gross proceeds under the third tranche of $300,000 and aggregate gross proceeds under the Financing of approximately $12,800,000. Together with the gross proceeds of $100,000 from the Company's previously announced non-brokered private placement of common shares, the total gross proceeds raised in connection with the Proposed Transaction (as defined below) is approximately $12,900,000. Unless otherwise stated, all amounts referred to herein are in Canadian dollars.

The Subscription Receipts issued pursuant to the third tranche of the Financing were issued to a strategic investor (the "Strategic Investor"). In connection with the subscription, the Company and the Strategic Investor entered into an investor rights agreement that will become effective upon completion of the Proposed Transaction, pursuant to which the Strategic Investor is entitled to certain rights provided that it maintains certain ownership thresholds in the Resulting Issuer (as defined below), including: (a) the right to participate in equity financings of the Resulting Issuer to maintain its pro rata ownership at the time of such financing or to acquire up to a 9.99% ownership interest, on a partially diluted basis, in the Resulting Issuer; and (b) the right (which the Strategic Investor has indicated it has no present intention of exercising) to nominate one person (and in the case of an increase in the size of the board of directors of the Resulting Issuer to eight or more directors, two persons) for election or appointment to the Resulting Issuer's board of directors.

Summary of the Financing

Pursuant to the terms of an agency agreement among the Company, TCP1 Corporation ("TCP1"), Cormark Securities Inc. and Stifel Canada, as co-lead agents (the "Agents"), under the third tranche of the Financing, the Company issued an aggregate of 1,666,667 Subscription Receipts at a price of $0.18 per Subscription Receipt. The third tranche of the Financing was completed in connection with the previously announced business combination and reverse takeover transaction of the Company, pursuant to which the Company will acquire all of the issued and outstanding shares of TCP1 in exchange for common shares of the Company (the "Proposed Transaction"). The Company, upon completion of the Proposed Transaction (referred to herein as the "Resulting Issuer"), is expected to continue trading on the TSX Venture Exchange (the "TSXV") as a tier 1 mining issuer under its current symbol "ACOP".

In accordance with the terms and conditions of the subscription receipt agreement entered into among the Company, the Agents and TSX Trust Company, as escrow agent (the "Subscription Receipt Agreement"), each Subscription Receipt will automatically convert into one pre-Consolidation (as defined below) common share of the Resulting Issuer ("Resulting Issuer Shares") upon the completion or satisfaction of certain escrow release conditions, including, among other things, the receipt of all necessary corporate, regulatory, shareholder and other approvals or consents necessary in connection with the Proposed Transaction and the completion or satisfaction of all of the conditions precedent to the Proposed Transaction, substantially in accordance with the definitive agreement entered into in connection therewith, other than the Consolidation and the amalgamation of TCP1 and 1000723052 Ontario Corporation (the "Amalgamation"), to the satisfaction of the Agents (collectively, the "Escrow Release Conditions"), provided that the Escrow Release Conditions are satisfied or waived prior to 5:00 p.m. (Toronto time) on March 31, 2024 (the "Escrow Release Deadline"). Immediately following the release of the gross proceeds of the third tranche of the Financing from escrow upon satisfaction of the Escrow Release Conditions and the conversion of the Subscription Receipts into Resulting Issuer Shares, the Company intends to complete a consolidation of the issued and outstanding Resulting Issuer Shares on the basis of one post-Consolidation common share for each six (6) pre-Consolidation common shares (the "Consolidation") and complete the Amalgamation, all in accordance with the terms of the Proposed Transaction.

In the event that the Escrow Release Conditions have not been satisfied or waived (to the extent such waiver is permitted) prior to the Escrow Release Deadline or if the Company announces to the public that it does not intend to satisfy the Escrow Release Conditions, or that the Proposed Transaction has been terminated, the aggregate issue price of the Subscription Receipts together with any earned interest shall be returned to the applicable holders of the Subscription Receipts (net of any applicable withholding taxes), and such Subscription Receipts shall be automatically cancelled and be of no further force and effect.

The Subscription Receipts sold under the Financing will be subject to a restricted hold period under applicable Canadian securities laws. The Resulting Issuer Shares issuable on conversion of the Subscription Receipts in connection with the Proposed Transaction will not be subject to a restricted hold period under applicable Canadian securities laws. The Financing remains subject to the approval of the TSXV. The Company did not pay any cash commissions or issue any compensation warrants in connection with the third tranche of the Financing.

The net proceeds of the Financing will be used to advance exploration programs across the Resulting Issuer's combined portfolio, with particular focus on Cristina and Yecora, and for general corporate purposes.

The securities offered in the Financing have not been, and will not be, registered under the U.S. Securities Act of 1933, as amended (the "U.S. Securities Act") or any U.S. state securities laws, and may not be offered or sold in the United States or to, or for the account or benefit of, United States persons absent registration or any applicable exemption from the registration requirements of the U.S. Securities Act and applicable U.S. state securities laws.
