ST. AUGUSTINE ANNOUNCES EXECUTION OF US$30 MILLION CONVERTIBLE NOTE WITH TVI RESOURCE DEVELOPMENT PHILS., INC.

St. Augustine Gold and Copper Ltd. has entered into an unsecured convertible note in the principal amount of $30-million (U.S.) with TVI Resource Development Phils. Inc. (TVI).

The note matures nine months from the date the principal is advanced, unless extended by mutual agreement, and bears interest at term SOFR (secured overnight financing rate) plus 3.00 per cent per annum, payable quarterly. TVI may elect to convert all or part of the principal and any accrued and unpaid interest into common shares of the company at a conversion price of 17.5 Canadian cents per share, being the closing price of the company's shares on the Toronto Stock Exchange on June 26, 2026, the date of the company's annual general meeting at which shareholders approved the financing. For conversion, amounts outstanding under the note will be translated from United States dollars into Canadian dollars at the exchange rate on the conversion date.

The proceeds of the note will be used to advance the Kingking copper-gold project, including completion of the definitive feasibility study and related technical studies and permitting; for operating and corporate expenses and general working capital; and to repay approximately $10-million (U.S.) owing by the company to Metanoia South Pte. Ltd. Further details are set out in the company's management information circular dated May 18, 2026, available on SEDAR+.

Related party and approvals

TVI is a related party of the company because Manuel Paolo A. Villar, the president and chief executive officer of the company, is the controlling shareholder and an officer of TVI, and other officers and directors of the company hold similar positions with TVI. The company's entry into the convertible note financing with TVI was approved by the company's disinterested shareholders at the annual general meeting held on June 26, 2026, with approximately 99.63 per cent of the votes cast by disinterested shareholders in favour.

The TSX has conditionally approved this private placement, subject to the company fulfilling all of the requirements of the exchange. The note, and any common shares issued on conversion, are subject to a hold period expiring four months and one day after the date of issuance of the note, in accordance with applicable securities laws.
