Pinnacle Silver and Gold Corp. has intersected 6.19 g/t gold and 90 g/t silver over a core length of 10.89 metres in underground drilling at the historic Pinos Cuates mine within the El Potrero project in Durango, Mexico.

Hole EPUG26068 was drilled up-dip from the Main Level and targeted the Dos de Mayo vein. The intercept included a higher-grade section yielding 58.2 g/t gold and 631 g/t silver over 0.41 metres, featuring visible gold and silver sulphides. The new intersection lies approximately 15 metres down-dip from hole EPUG26035, which previously intersected 13.18 metres grading 9.69 g/t gold and 143 g/t silver.

Pinnacle has drilled 76 holes to date at Pinos Cuates, with assays reported for the first 53 holes. Earlier underground channel sampling across rehabilitated workings identified grades up to 26.1 g/t gold and 511 g/t silver over 0.5 metres.

“We are very pleased to see the continuity of grade in this area of the Pinos Cuates mine,” stated Robert Archer, President and CEO of Pinnacle. “Hole EPUG26068 was assayed on a ‘rush’ basis due to the visibly apparent high-grade mineralization and to allow time for follow-up drilling before the drill was moved to the Dos de Mayo mine.” — Robert Archer, President and CEO

Underground drilling is ongoing at the Pinos Cuates mine before the rig moves to test the Dos de Mayo mine, starting with hole EPUG26084. Assays are pending for additional completed holes.

In the surrounding district, Luca Mining Corp. intersected 9.9 metres grading 5.39 g/t gold equivalent at the Catorce Zone of its Tahuehueto mine.

Surface drilling at El Potrero is anticipated to commence in October 2026 to fill gaps between historic workings and test parallel structures. Pinnacle will use the combined drill results to generate an internal resource estimate and develop a preliminary mine plan.

Surface exploration and upcoming resource estimation work will help establish the project's maiden development parameters as the company advances El Potrero toward potential near-term production.
