GR Silver Mining Ltd (TSX-V:GRSL) has announced the final batch of underground drilling results from the Plomosas Mine Area, part of the 2022 infill and exploratory drilling program at the company's wholly-owned Plomosas Project in Sinaloa, Mexico.
The drilling results continue to reveal attractive wide high-grade silver-polymetallic mineralization in unmined areas at the upper levels of the historic underground mine. These results continue to demonstrate the potential to incorporate wide and attractive polymetallic results into the upcoming resource estimation, scheduled for completion by the end of the first quarter of 2023.
"The upcoming resource estimation is expected to define a significant resource dominated by silver mineralization over broad widths, relatively close to surface or existing underground infrastructure,” GR Silver Mining chairman and CEO, Eric Zaunscherb said in a statement.

“We consider these attributes to contribute to GR Silver Mining's competitive advantages, along with project scale and prospectivity, and the management and board skills to take the project to the next level. We anticipate a potential market re-rating related to the resource estimation update, based on scale and quality of resources."
Highlights from the underground drilling results (Downhole widths):
- PLIP22-094: 21.7 metres (m) at 158 grams per ton (g/t) Ag (silver), 0.05 g/t Au (gold), 1.9% Pb (lead), 1.8% Zn (zinc) and 0.1% Cu (copper) - 301 g/t AgEq - including 5.8m at 427 g/t Ag, 0.09 g/t Au, 4.9% Pb, 1.4% Zn and 0.1% Cu - 648 g/t AgEq
- PLIP22-092:13.0m at 161g/t Ag, 0.20 g/t Au, 1.0% Pb, 1.5% Zn and 0.1% Cu - 273 g/t AgEq
- PLIP22-089: 5.4m at 325 g/t Ag, 0.54 g/t Au, 3.1% Pb, 2.5% Zn and 0.1% Cu - 567g/t AgEq including:2.5m at 524 g/t Ag, 0.19 g/t Au, 2.7% Pb, 0.8% Zn and 0.1% Cu - 660 g/t AgEq
- PLIP22-078: 4.7m at 277 g/t Ag, 0.75 g/t Au, 7.5% Pb, 2.1% Zn and 0.2% Cu - 666 g/t AgEq
The 186 drill holes (11,750m), completed by GR Silver Mining at the Plomosas Mine Area since the 2021 resource estimation, have added important core drilling in specific areas of the existing NI 43-101 resource block model, which together with 36,400m of historical drilling completed by First Majestic, Aurcana and IMMSA, provide a higher density and confidence of information for the resource estimation in progress.
GR Silver Mining is a Canadian-based, Mexico-focused junior mineral exploration company engaged in cost-effective silver-gold resource expansion on its 100%-owned assets, located on the eastern edge of the Rosario Mining District, in the southeast of Sinaloa State, Mexico.
