GR Silver Mining Releases High-grade Silver Results from San Marcial Resource Expansion Drilling Program – 15.4 m at 547 g/t Ag, including 2.0 m at 1,179 g/t Ag
GR Silver Mining Ltd. (“GR Silver Mining” or the “Company”) (TSXV: GRSL) (OTCQB: GRSLF) (FRANKFURT: GPE) – announces first assay results from the 2022 resource expansion drill program at the San Marcial Area in Sinaloa, Mexico. The high-grade silver (“Ag”) results demonstrate the potential for resource expansion both near-surface and at depth at 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 (Figure 1). Results from the remaining drill hole of the 2021 program, which targeted NW strike extensions of the mineralized hydrothermal breccia, are also reported in this news release.
