Together with the proceeds from the Bridge Financing, the total gross proceeds raised in connection with the Proposed Transaction (as defined below) is approximately $12,500,000. As a result of the closing of the second tranche of the Concurrent Financing, the Company has now satisfied the concurrent financing condition in connection with the Amalgamation (as defined below). Unless otherwise stated, all amounts referred to herein are in Canadian dollars.

Summary of the Concurrent Financing

Pursuant to the terms of an agency agreement between the Company, TCP1, Cormark Securities Inc. and Stifel Canada, as co-lead agents (the "Agents"), under the second tranche of the Concurrent Financing, the Company issued an aggregate of 30,782,634 Subscription Receipts at a price of $0.18 per Subscription Receipt. The second tranche of the Concurrent Financing was completed in connection with 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 ("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 herein) 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 Escrowed Funds (as defined below) 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.

In consideration of the Agents' services rendered in connection with the second tranche of the Concurrent Financing, the Agents shall be entitled to a cash commission of $176,455.09, being a cash commission equal to 6.0% of the aggregate gross proceeds from the sale of the Subscription Receipts (the "Agents' Commission"). Calculation of the Agents' Commission excludes (i) the sale of 7,250,000 Subscription Receipts to a certain purchaser, for which no cash commission was paid to the Agents; and (ii) sales to purchasers on a president's list, in respect of which a 3.0% cash commission was paid to the Agents (the "Excluded Sales"). As additional compensation, the Agents were issued 980,306 compensation warrants (the "Compensation Warrants") exercisable to acquire 980,306 Resulting Issuer Shares, being that number of Resulting Issuer Shares as is equal to 6.0% of the aggregate number of Subscription Receipts issued pursuant to the second tranche of the Concurrent Financing, other than the Excluded Sales. Each Compensation Warrant shall be exercisable at a price of $0.18 per Resulting Issuer Share (prior to giving effect to the Consolidation) for a period of 24 months following the completion of the Proposed Transaction. The gross proceeds of the second tranche of the Concurrent Financing (including, for certainty, the Agents' Commission) less certain expenses paid to the Agents (the "Escrowed Funds") have been placed into escrow and, upon completion or satisfaction of the Escrow Release Conditions in accordance with the Subscription Receipt Agreement, the Agents' Commission and the remaining Escrowed Funds, together with any earned interest, will be released to the Agents and the Company, respectively.

The Subscription Receipts sold under the Concurrent 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 Concurrent Financing remains subject to the approval of the TSXV.

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

The securities offered in the Concurrent 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. This news release shall not constitute an offer to sell or the solicitation of an offer to buy securities in the United States, nor shall there be any sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.
