GR Silver drills 112 g/t silver over 123.1 metres at Plomosas, Mexico

GR Silver Mining Ltd. [GRSL-TSXV; GRSLF-OTCQB; GPE-FSE] has completed follow up drilling lateral to the new high-grade Southeast area (SE area) silver (Ag) discovery, at the wholly owned Plomosas project, Sinaloa, Mexico.

Surface drill hole SMS22-16 intersected mineralization similar to the previously announced SMS22-10 discovery in the SE area, on a 90-metre step-out drilling program, where multiple high-grade intervals are hosted in a wide zone with a predominance of Ag-rich hydrothermal breccias and stockworks, to the southeast of the San Marcial resource area.

Highlights from the Southeast area surface drilling results at San Marcial: SMS22-16: identified a wide hydrothermal breccia and stockwork system, with multiple high-grade Ag intervals, similar to the wide hydrothermal system in the SMS22-10 discovery hole. SMS22-16 intersections returned 123.1 metres at 112 g/t Ag, including 13.1 metres at 289 g/t Ag, including 0.4 metres at 4,680 g/t Ag, 27.3 metres at 250 g/t Ag,  including 0.3 metres at 1,351 g/t Ag and 6.4 metres at 635 g/t Ag, including 0.5 metres at 2,203 g/t Ag.

SMS22-14: Confirmation of Ag mineralization at shallow depth 150 metres along strike from the SE area. Presence of wide Ag mineralization with isolated high-grade values. SMS22-14 intersections returned 10.5 metres at 23 g/t Ag and 3.5 metre at 118 g/t Ag, including 0.2 metres at 1,790 g/t Ag.

The drilling program continues at the SE area, to define the geometry and lateral extents of the mineralization. The results to date suggest that the high-grade, wide Ag mineralization can be present at shallow depth from surface where Ag values are relatively low, as seen in shallow hole SMSP22-023.

The occurrence of Ag anomalous zones on surface along the 1.5-kilometre target contact, further southeast from the SE area, provides new targets for the company to continue drilling, aimed at expanding the footprint of mineralization and potentially for incorporation into the planned resource estimation update in Q1 2023.

Eric Zaunscherb, chairman and CEO, commented, “With each new drill hole, the Company’s understanding of the controls on mineralization in the new SE Area, as well as its size and geometry, increase. The systematic approach capturing geochemical, geophysical, and geological data at surface, is informing shallow drilling (e.g., hole SMSP22-023), which, in turn, guides us at depth (e.g., SMS22-16). The evidence appears to be pulling us further to the southeast and the ongoing fully funded drill program will continue to generate data for the mineral resource estimate update scheduled for the first quarter of 2023.”

Following the recent discovery of wide, high-grade Ag mineralization in the SE Area of San Marcial, the company continues to drill holes to test the geometry and continuity of mineralization at depth and laterally.
