About GR Silver Mining Ltd.

GR Silver Mining is a Canadian-based, Mexico-focused mineral exploration company engaged in cost-effective silver-gold resource expansion on its 100-per-cent-owned assets, located on the eastern edge of the Rosario mining district, in the southeast of Sinaloa state, Mexico. GR Silver Mining controls 100 per cent of the Plomosas project, including both the high-grade silver discovery at the San Marcial area and the former Plomosas underground mine. Recent discoveries in the 78 square kilometres of highly prospective, advanced-stage exploration concessions position the company well for resource expansion at the Plomosas project.
