GR Silver Mining Ltd. Announces Temporary Pause in Field Work at Plomosas Silver Project

VANCOUVER, BC, April 29, 2025 — GR Silver Mining Ltd. (“GR Silver Mining” or the “Company”) (TSXV: GRSL) (OTCQB: GRSLF) (FRANKFURT: GPE) has announced a temporary pause in field work at its Plomosas Silver Project located in Sinaloa, Mexico. This decision comes despite the absence of any incidents of violence on the Company’s properties or threats to its employees and consultants.

The pause is a precautionary measure to allow time for the Government of Mexico to enhance security and stability in the region. This decision follows the Company’s announcement on March 3, 2025, regarding the commencement of a step-out drilling program. The program aims to expand the San Marcial mineralization footprint by approximately 350 meters northwest from the current NI 43-101 resource area and to test potential new parallel zones.

As part of the initial drilling program, the Company has already drilled and sampled the first hole in the NW Extension zone. The temporary halt in field work is intended to ensure the safety of the Company’s operations and personnel while the government’s efforts to improve regional security are underway.
