GR Silver Mining Ltd. (TSXV: GRSL) has undertaken successful follow up drilling lateral to the new high-grade Southeast Area (SE Area) silver (Ag) discovery, at the company’s wholly-owned Plomosas Project, in Sinaloa, Mexico.
Surface drill hole SMS22-16 intersected mineralisation similar to the previously announced SMS22-10 discovery in the SE Area, on a 90 m step out drilling programme, where multiple high-grade intervals are hosted in a wide zone with a predominance of Ag-rich hydrothermal breccias and stockworks, to the SE 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 are summarised as: 123.1 m at 112 g/t Ag including: 13.1 m at 289 g/t Ag including 0.4 m at 4,680 g/t Ag, 27.3 m at 250 g/t Ag including 0.3 m at 1,351 g/t Ag and 6.4 m at 635 g/t Ag including 0.5 m at 2,203 g/t Ag
- SMS22-14: Confirmation of Ag mineralisation at shallow depth 150 m along strike from the SE Area. Presence of wide Ag mineralisation with isolated high-grade values. SMS22-14 intersections are summarised as: 10.5 m at 23 g/t Ag and 3.5 m at 118 g/t Ag including 0.2 m at 1,790 g/t Ag
- The drilling programme continues at the SE Area, to define the geometry and lateral extents of the mineralisation. The results to date suggest that the high-grade, wide Ag mineralisation 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 km target contact, further SE 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|23.
“With each new drill hole, the company’s understanding of the controls on mineralisation in the new SE Area, as well as its size and geometry, increase,” Chairman and CEO, Eric Zaunscherb, said.
“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 programme will continue to generate data for the mineral resource estimate update scheduled for the first quarter of 2023.”
