About Plomosas Project
GR Silver Mining’s Plomosas Project is located on the southwestern edge of the Sierra Madre Occidental, a world renowned region for discovery, development and operation of silver mines in Mexico. The Project is in the historic Rosario Mining District, Sinaloa, Mexico and covers 78 km² of 100%-owned concessions and permitted historic underground mines. The Plomosas Project integrates the past producing Plomosas Mine and San Juan-La Colorada Areas, and the recently discovered extensive wide and shallow silver mineralization at the San Marcial Area. The existing infrastructure, combined with available permits, offers significant opportunities for future mine and operational developments, resource growth, and supports the Company’s growth in one of Mexico’s richest silver-gold-lead-zinc mining districts.
