Pinnacle Silver and Gold Announces Underground Drilling Program at El Potrero Project

VANCOUVER, BRITISH COLUMBIA — December 15, 2025 — Leads & Copy — Pinnacle Silver and Gold Corp. (TSXV:PINN) will begin an underground drilling program at its El Potrero gold-silver project in Durango, Mexico. The program will include approximately 2,600 meters in 112 holes. The company's geological team, led by Jorge Ortega, QP, has prepared 3D models to test the Dos de Mayo vein structure every 12.5 meters. Underground channel sampling has identified high-grade gold-silver mineralization with grades up to 85.1 g/t Au and 520 g/t Ag. Development work is expected to begin early in the New Year and take about one month to complete before drilling begins.

Robert Archer, Pinnacle’s President & CEO, noted that it is not common that the first drill program on a new project is underground. He also stated that with the results of this program, the company will gain a very good understanding of the principal mineralized zones and can begin putting together a preliminary mine plan.
