GR Silver Mining (TSXV:GRSL) has reported new results from its final round of underground drilling at the Plomosas Mine Area during its 2022 infill and exploratory drilling program at the Plomosas Project in Mexico. The company drilled all 28 drill holes in the announcements from within the historic Plomosas Mine Area, mainly about the 900 level. 

Drill targeted the wide polymetallic Plomosas Breccia in unmined areas close to existing underground development and access. Objectives for the infill drilling program were achieved and delineated new mineralized zones, replacing un-sampled historical holes that were previous adopted in the 2021 resource estimation. 

GR Silver Mining Chairman and CEO, Eric Zaunscherb commented in a press release: “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. 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 results are as follows:

• PLIP22-094: 21.7 m at 158 g/t Ag, 0.05 g/t Au, 1.9% Pb, 1.8% Zn and 0.1% Cu (301 g/t AgEq1)
  including: 5.8 m 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: 13.0 m 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: 5.4 m at 325 g/t Ag, 0.54 g/t Au, 3.1% Pb, 2.5% Zn and 0.1% Cu (567g/t AgEq)
  including: 2.5 m 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: 4.7 m 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 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 Q1|2023.

The 186 drill holes (11,750 metres), 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 36,400 metres of historical drilling completed by First Majestic, Aurcana and IMMSA, provide a higher density and confidence of information for the resource estimation in progress.
