ST. AUGUSTINE ANNOUNCES THE APPOINTMENT OF BMO CAPITAL MARKETS AND MACQUARIE CAPITAL AS FINANCIAL ADVISORS FOR ADVANCEMENT OF THE KINGKING COPPER-GOLD PROJECT

St. Augustine Gold and Copper Ltd. has appointed BMO Capital Markets and Macquarie Capital as financial advisers in relation to financing and strategic alternatives for the advancement of the Kingking copper-gold project in the Philippines.

Following the release of the Kingking project National Instrument 43-101 prefeasibility study report on July 31, 2025, and the recent engagement of Stantec and IMC to complete a definitive feasibility study, the board of directors has approved the engagement of BMO Capital Markets and Macquarie Capital to support the company's objective to advance the Kingking project toward production.

As previously disclosed, the Kingking prefeasibility study demonstrates highly robust economics, including a $4.2-billion (U.S.) net present value (7 per cent), a 34.2-per-cent internal rate of return and a 1.9-year payback (at $2,150 (U.S.) per ounce gold and $4.30 (U.S.) per pound copper), supporting the board of directors' recommendation and actions to move toward project development.

The company will pursue a financing strategy to support the project development schedule targeting first production of concentrate in 2030, with the support of BMO Capital Markets and Macquarie Capital.

The engagement of the advisers marks a new milestone in the company's commitment to progress the Kingking project toward development in accordance with global industry standards and regulatory requirements.

"Appointing these experienced advisers and consultants reflects our board's commitment to advancing the Kingking project responsibly, transparently and in line with best practices," said Nicolaos Paraskevas, executive director. "We look forward to working with BMO Capital Markets, Macquarie Capital, Stantec and IMC to unlock the value of this strategic copper-gold asset for our stakeholders."

The Kingking copper-gold project is one of the largest undeveloped copper-gold deposits in Southeast Asia and has been declared a project of national significance under Executive Order No. 79 (Philippines). The project is being advanced in compliance with both Philippine mining regulations and international reporting standards.
