GR Silver Mining Ltd. (GRSL.V) is a Mexico-focused company engaged in cost-effective resource expansion and controlling the key assets on the eastern edge of the Rosario Mining District. GR Silver Mining owns the Plomosas Silver Project located near the historic mining village of La Rastra, within the Rosario Mining District. The silver and gold mineralization display the alteration, textures, mineralogy and deposit geometry characteristics of a low sulphidation epithermal silver-gold-base metal vein/breccia mineralized system. Previous exploration focused on Pb-Zn-Ag-Au polymetallic shallow mineralization, hosted in NW-SE structures in the vicinity of the Plomosas mine. The E-W portion of the mineralization remains under-explored. The Company is engaged in underground development and additional drilling at the San Marcial Project, which is a near-surface, high-grade silver, lead, and zinc open pit amenable project. GR Silver Mining is currently expanding its NI 43-101 resource estimate at the San Marcial project, which contains 36 Moz AgEq (indicated) + 11 Moz AgEq (Inferred), by defining new high-grade gold and silver targets along the project’s 6 km mineralized trend. Other GR Silver Mining projects are situated in areas attractive for future development in the vicinity of Plomosas and San Marcial within the Rosario Mining District. Our experienced exploration team has over 10 years of experience in the Rosario District with a record of successful discoveries, including the extension of La Trinidad mine, one of Mexico’s highest grade, open pit gold mines.
