Not for distribution to United States newswire services or for dissemination in the United States.

Vancouver, British Columbia, March 20, 2026, Drummond Ventures Corp. (TSXV: DVX.P) ("Drummond") and Toro Silver Corp. ("Toro"), a corporation incorporated under the laws of the Province of British Columbia, announce further details regarding the proposed business combination of Drummond and Toro (the "Proposed Transaction"), as previously announced in the press release of Drummond dated December 31, 2025. The Proposed Transaction will constitute Drummond's Qualifying Transaction, as such term is defined in Policy 2.4 Capital Pool Companies ("Policy 2.4") of the TSX Venture Exchange (the "Exchange"). Drummond and Toro are also pleased to announce that they have received the conditional approval of the Exchange to the Proposed Transaction.

Prior to the completion of the Proposed Transaction, Toro and Drummond intend to complete a non- brokered private placement (the "Concurrent Financing") of up to 42,857,142 subscription receipts (each, a "Subscription Receipt") at a purchase price of US$1.40 per Subscription Receipt for gross proceeds of up to US$60,000,000. Toro and Drummond reserve the right to increase or decrease the size of the Concurrent Financing. The Concurrent Financing will consist of the issuance of Subscription Receipts of Toro (each, a "Toro Subscription Receipt") and Subscription Receipts of Drummond (each, a "Drummond Subscription Receipt"), at the same issue price. Each Toro Subscription Receipt will, upon satisfaction of certain escrow release conditions, be converted into one common share of Toro, which will immediately be exchanged for one post-consolidation common share of Drummond (a "Resulting Issuer Share") on completion of the Proposed Transaction. Each Drummond Subscription Receipt will, upon satisfaction of certain escrow release conditions, be converted into one Resulting Issuer Share.

Upon completion of the Proposed Transaction, Drummond will be renamed "Mackay Gold & Silver Corp." (the "Resulting Issuer") and will commence trading on the Exchange under the symbol "MACK".

On closing of the Concurrent Financing, the gross proceeds will be held in escrow by a subscription receipt agent. The escrowed funds shall be released to Toro and Drummond upon the completion of certain escrow release conditions in connection with the Proposed Transaction. In the event that the escrow release conditions are not satisfied or waived by 90 days following the completion of the Concurrent Financing or such later date as determined in accordance with the terms of the subscription receipt agreements or, if prior to such time, the amalgamation agreement between Toro and Drummond is terminated, or either Toro or Drummond advise the subscription receipt agent that it does not intend to, or that it cannot, satisfy the escrow release conditions, then the outstanding Subscription Receipts shall be cancelled and terminated and the escrowed funds shall be returned to the applicable subscribers of the Subscription Receipts.

Toro and Drummond intend to use the proceeds of the Concurrent Financing towards mineral exploration expenditures on Toro's Comstock mining property in Nevada, exploration salaries and consulting fees, mineral property holding costs and for general working capital purposes. Toro and Drummond may pay finder's fees in cash or securities in connection with the Concurrent Financing.

The Drummond Subscription Receipts, and the Resulting Issuer Shares issued on conversion thereof, will be subject to a four-month hold period from the date of issuance of the Drummond Subscription Receipts in accordance with applicable securities laws. The Private Placement is subject to the approval of the Exchange.
