GR Silver Mining (GRSL.V) said resource expansion diamond drilling at the San Marcial area on the Plomosas Project in Mexico has confirmed high-grade silver mineralization on the southeast target extending for least an additional 150 meters.
Drillhole SMS26-07 intersected two distinct mineralized zones, with highlights including 21.9 m at 168 grams per tonne (g/t) silver, including 6.15 m at 447 g/t silver in the southeast area. the company said.
"The results from two new resource expansion areas at San Marcial demonstrate the continued effectiveness of our 20,000-meter drilling program and reinforce our confidence in the exploration potential of both the Southeastern Extension and the Parallel Breccia," said chief executive Eric Zaunscherb.
