VANCOUVER, BC, Sept. 8, 2021 /CNW/ – GR Silver Mining Ltd. (“GR Silver Mining” or the “Company”)(TSXV: GRSL) (OTCQB: GRSLF) (FRANKFURT: GPE) – announces that it has received high-grade results from the exploration sampling program of newly discovered Au-Ag rich epithermal veins in the GAP Area, located between the San Juan and San Marcial Areas in Sinaloa, Mexico.
Highlights
Channel sampling highlights include:
- 0.30 m @ 10.72 g/t Au and 251 g/t Ag
- 0.35 m @ 0.81 g/t Au and 1,450 g/t Ag
- 0.30 m @ 2.77 g/t Au and 363 g/t Ag
Rock chip sampling highlights include:
- 0.54 g/t Au with 3.5% Pb and 11.8% Zn
- 1.60 g/t Au with 440 g/t Ag
- Results to be followed up by recently announced surface core drill program
GAP Area Discovery
Since the acquisition of 100% of the concession containing the GAP Area in March 2021, GR Silver Mining’s team has advanced an exploration program that links the San Marcial, San Juan and Plomosas Areas. The Company now controls seven kilometres of structural trend between San Marcial and San Juan, which hosts the new GAP Area discovery (Figure 1).
Over the past months, the Company has completed geological mapping, reconnaissance of old workings, a ground geophysical survey and collected channel samples over an extensive epithermal vein system within the GAP Area. This key zone links two areas that now host NI 43-101 mineral resource estimates1,2, and has not previously been explored.
Initial reconnaissance and sampling indicate that the high-grade Au-Ag concentrations are associated with well zoned, low-temperature epithermal veins and include amethystine quartz, among other quartz types, and with low sulphide content. Locally, some of the veins exceed 10% combined lead and zinc (Table 1). Systematic sampling of the different veins led to the definition of a 2 km2 large prospective zone in the GAP area.
The mapped geology shows that the volcaniclastic-sedimentary and andesitic tuff units that host the veins in the GAP Area are likely to be underlain by several intrusive diorite plugs.
GR Silver Mining’s discovery of Au-Ag rich veins in the GAP Area supports the proposed model of a large district-scale vein and breccia system between the San Marcial and San Juan Areas. The GAP Area is one of five new areas in the Company’s current drill program, which is testing areas outside of the recently announced NI 43-101 mineral resource estimates2.

GR Silver Mining President and CEO, Marcio Fonseca commented “The progress of GR Silver Mining’s exploration program in new areas continues to deliver positive results. We are encouraged by the initial results from the GAP Area, as well as the magnitude of the epithermal system based on our first ever sampling program. Drilling is planned to further test the high-grade mineralization in the GAP Area. These first high-grade gold and silver values show that the GAP Area has significant potential to connect the seven kilometre long vein system from San Marcial to San Juan, as another step in consolidating the mineral potential of the entire Plomosas Project.”
