GR Silver Mining hails drill results from first underground program at San Marcial, which extend mineralization below resource

GR Silver Mining (TSX-V:GRSL) Ltd has reported positive drill results from the Plomosas project in Mexico, which have extended mineralization below the San Marcial resource.

The assays come from three holes of an eight-hole program, the first underground drilling undertaken at San Marcial, and confirmed extensions of high-grade silver at “attractive widths and grades” along strike and up to 170 metres (m) down-dip.

Highlight drill results from the San Marcial Breccia included 1,792 grams per ton (g/t) silver over 5.6m from 184.5 m downhole in one hole and 773 g/t of silver over a width 18.5m from 179.4m depth.

“The first drill results from our resource expansion program at San Marcial have proven the consistency and continuity of the Ag-rich San Marcial Breccia mineralization, along strike and down dip,” said GR Silver Mining (TSX-V:GRSL)‘s CEO Marcio Fonseca in a statement.

“Based on such encouraging initial assay results we are anticipating continued positive results for the remainder of the drill core currently at the laboratory. The introduction of a modern exploration approach by the GR Silver Team is delineating an extensive hydrothermal system with presence of high-grade silver mineralization, proving continuity of the San Marcial Breccia down dip to support resource expansion. It is also delineating wide Au mineralized zones, which will be the subject of additional drilling in 2022,” Fonseca added.

The 1,250 hectare (Ha) property sits 5 kilometres (km) south of the Plomosas project. An NI 43-101 resource for San Marcial showed 36 million indicated ounces (Moz) of silver-equivalent.

GR said it anticipates assay results from the remaining five drill holes in coming months. Once received, the 3-dimensional geological model will be updated and further surface and/or underground drilling will be delineated, it added.

The company is focused on cost-effective silver-gold resource expansion at its 100%-owned assets, which are on the eastern edge of the Rosario Mining District, in the southeast of Sinaloa State, Mexico.
