Vancouver, British Columbia--(Newsfile Corp. - May 13, 2025) - 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."

Salvador Garcia, B. Eng., a director of the Company and Chief Operating Officer, is the Company's qualified person on the project as required under NI 43-101and has prepared the technical information contained in this press release.
