STARCORE ANNOUNCES

Fourth Quarter Production Results

Vancouver, B.C. – Starcore International Mines Ltd . (TSX: SAM) (“ Starcore” or the “ Company”)

announces production results for the fourth fiscal quarter ended April 2025, at its San Martin Mine (“San

Martin”) in Queretaro, Mexico.

This quarter, Starcore achieved a significant milestone in commissioning the new processing circuit, including

the ADR plant, for carbonaceous ore treatment. To date, the plant has milled 5,000 tonnes of stockpiled ore

grading 2.1 g/t of gold and 26 g/t of silver in the start-up phase. Recoveries were 80% for gold and 76% for

silver, as expected based on metallurgical investigations, with a Doré production of 180 gold equivalent

ounces. The mine has ramped up development and mining activity as planned, producing 140 tonnes per day

of carbonaceous ore, and we have engaged a contractor for the necessary additional works.

Other operations continue as normal, exploring and developing a new area in the southern part of the mine,

where the San Martín mine began 30 years ago as an open-pit operation and are now focused on the depths of

that area called the San José mine.

“We are very excited about the success of the new carbonaceous ore process, as it represents an extension of

the mine life,” stated Salvador García, the Company’s Chief Operating Officer. “This paves the way for

continuing to explore the great potential we have at San Martín, in oxides and carbonaceous ore.”
