GR Silver Mining Ltd reports high-grade silver results from San Marcial resource expansion drilling program in Mexico

GR Silver Mining (TSX-V:GRSL) Ltd revealed impressive first assay results from its 2022 resource expansion drill program at the San Marcial area in Sinaloa, Mexico.

The Vancouver-based, Mexico-focused junior mineral exploration company said the high-grade silver (Ag) results demonstrate the potential for resource expansion both near-surface and at depth in the San Marcial Area. The 23 released drill holes targeted delineation of near-surface high-grade zones, as well as the lateral continuation of mineralization along the prospective contact between the upper andesitic “block and ash” unit and lower volcano-sedimentary units. This contact commonly hosts the San Marcial Area Ag mineralization.

The company also reported results from the remaining drill hole of the 2021 program, which targeted the NW strike extensions of the mineralized hydrothermal breccia.

The success of the 2022 drilling has led GR Silver to extend its program further to the SE of the southern limit of the current NI 43-101 San Marcial Resource Area. Additional drilling will continue to target new discoveries along strike, following the key geological contact zone.

In a statement, GR Silver Mining (TSX-V:GRSL) Chairman and CEO Eric Zaunscherb, said: “It is very exciting to see exploration concepts, like the potential for additional high-grade precious metal mineralization extending to the SE of San Marcial, come to fruition.”

He added: “Recent results not only demonstrate this potential but also the potential for targeted infill drilling to capture the presence of near-surface, high-grade Ag and Au zones in the upcoming NI 43-101 update. Ongoing drilling is certainly proving the importance of understanding the structural controls on high-grade mineralization, with mounting anticipation of new discoveries as the geological onion is peeled.”

The company highlighted the results from the 23 holes as follows:

  • Attractive high-grade Ag results at shallow depth with the potential to increase Ag grades in the updated resource estimation scheduled for the first quarter of 2023 including:
  • SMSP22-003: Intersected 15.4 meters (m) at 547 grams per ton (g/t) Ag, including 2m at 1,179 g/t Ag
  • SMSP22-012: Intersected 15m at 324 g/t Ag, including 1m at 1,541 g/t Ag
  • SMS22-02: Intersected 2.8m at 455 g/t Ag, including 0.3m at 3,854 g/t Ag
  • SMSP22-010: Intersected 16.7m at 193 g/t Ag, including 2m at 921 g/t Ag
  • Near-surface Ag resource (0-20 m depth) within the NI 43-101 had limited previous drilling. This is now addressed with shallow, high-grade Ag intercepts from the current program;
  • The San Marcial mineralization is hosted by breccias along the contact between two different volcanic units: an upper unit represented by andesitic “block and ash”, and a lower unit represented by lapilli-ash tuffs. Recent mapping and geochemical sampling have confirmed the presence of Ag anomalies immediately SE of the NI 43-101;
  • An initial drill program is in progress to the SE of the NI 43-101 in some of these Ag anomalies, testing extensions along the key mineralized contact zone, where high-grade Ag hydrothermal breccias and related Ag-Au mineralization are present.
