Overview of the Plomosas Project
The Plomosas Project is GR Silver Mining’s flagship asset in the historic Rosario Mining District, Sinaloa, Mexico. Covering 78 km² of highly prospective concessions, the project integrates the Plomosas Mine Area, San Marcial Area, and La Trinidad Area, along with an additional 270 km² of adjacent non-core concessions. This extensive land package provides significant opportunities for resource growth, future development, and business partnerships across one of Mexico’s most productive silver-gold-lead-zinc belts.
Mineral Resource Update
In May 2023, GR Silver Mining published an updated NI 43-101 Technical Report and mineral resource estimate for the Plomosas Project, consolidating data from all major areas.
San Marcial Area
A near-surface, silver-dominant property with strong expansion potential, including a 2022 high-grade discovery within a multimillion-ounce mining district.
Plomosas Mine Area
A development-stage property with high-grade silver-gold-lead-zinc mineralization, 7.4 km of underground workings, and valid operating permits. The area hosts multiple drilled exploration targets and low-sulfidation epithermal vein discoveries, positioning it for near-term development and continued exploration upside.
