Highlights
Indicated Resources: 10.3 Moz AgEq* - 3.4 Moz Ag, 53 koz Au, 73 Mlbs Zn, and 48 Mlbs Pb
Inferred Resources: 21.0 Moz AgEq* - 8.6 Moz Ag, 85 koz Au, 149 Mlbs Zn, and 116 Mlbs Pb
The incorporation of extensive historical data and completion of the initial resource estimates at the Plomosas Project ("Plomosas") incremental to the nearby San Marcial NI 43-101 mineral resource estimate of 36.0 Moz AgEq# Indicated resources and 11.9 Moz AgEq# Inferred resources (see News Release dated June 12, 2020), represents a major milestone for GR Silver Mining
Estimates include 80 new drill holes and 476 historic drill holes representing a total of 100,672 m of drilling covering two areas, the former Plomosas Mine and the San Juan area (Figure 1)
The present resource included a sampling of historical drill holes completed by previous companies that was frequently selective, resulting in a large amount of drill core unsampled; this core is no longer available. Unsampled intervals within mineralized zones were assigned zero values for the resource estimation, including in areas with evidence of precious and base metals mineralization. Further drilling will address these blank spots to potentially continue resource growth at the Plomosas Mine and San Juan areas
A 14,000m drill program employing seven rigs is in progress on newly identified, high priority Au–Ag targets outside the current resource areas (Figure 1)
