Starcore Reports Second Quarter Production Results

Vancouver, British Columbia--(Newsfile Corp. - November 19, 2025) - Starcore International Mines Ltd. (TSX: SAM) ("Starcore" or "the Company") announces production results for the first fiscal quarter ended October 2025 at its San Martin Mine ("San Martin") in Queretaro, Mexico. Our metal production was lower again this quarter due to two main issues. The first was the presence of clay in the ore, which caused what's known as a "preg-robbing" effect where the clay traps some of the gold, reducing recovery. The second issue was that fine particles of activated carbon (called carbon fines) mixed with the pulp sent to the desorption process (ADR). These carbon fines absorbed gold and silver from the ore, which further lowered overall recovery rates. To address the clay-related issue, we optimized the use of the CIL plant to improve gold recovery. For the carbon fines problem, we installed two filter presses — one at the discharge of the ADR process and another in the thickener tank where the solution is recycled for reuse. In addition, to prevent any contamination between the two processing circuits, we are fully separating them. We are also installing a cyanide destruction module, which will allow the carbonaceous ore process to use a cyanide-free solution during grinding. With these improvements and the construction of the cyanide destruction module, we expect to restart processing the stockpiled carbonaceous ore at the mine this month. "We will have multiple sources of ore requiring different processing methods so as to continue to produce profitable ounces," stated Salvador García, the Company's Chief Operating Officer.         6 Month YTD   San Martin Production Q2 2026  Q1 2026  Q/Q Change  2026 2025   Y/Y Change  Ore Milled (Tonnes) 51,960 54,247 -4% 106,207 97,752 9% Gold Equivalent Ounces 1,860 2,130 -13% 3,991 4,307 -7% Gold Grade (Grams/Ton) 1.33 1.47 -10% 1.40 1.52 -8% Silver Grade (Grams/Ton) 14.48 12.88 12% 13.66 14.99 -9% Gold Recovery (%) 77.17 77.42 0% 77.31 83.45 -7% Silver Recovery (%) 49.30 54.78 -10% 51.94 54.40 -5% Gold: Silver Ratio   85.20     94.50           89.69     81.24           Salvador Garcia, B.
