07:18 AM EST, 11/19/2025 (MT Newswires) -- GR Silver Mining ( GRSLF ) reported Wednesday high-grade intercepts from the San Marcial resource area within the Plomosas project in Mexico.

The company said its step-out drilling intersected two silver mineralized zones with multiple intervals of high-grade silver. Highlights include 5 meters at 232 grams per tonne silver, including 0.9 meters at 956 g/t silver.

"The recent success of step-out drilling at the San Marcial Area in 2025 further strengthens our confidence in a large, continuous silver-mineralized system at San Marcial," President and Chief Executive Officer Marcio Fonseca said.

GR said it plans to conduct a significant step-out drilling program in the first half of 2026, aiming to double the existing silver mineralization footprint to support resource growth at San Marcial.

GR's share price gained 3.1% on Tuesday to C$0.25 on the TSX Venture Exchange.
