GR Silver Mining Intersects 44.5 m at 518 g/t AgEq Including 6.5 m at 2,101 g/t AgEq in the Footwall and Hanging Wall of the Main Mineralized Zone at the Plomosas Mine Area

GR Silver Mining Ltd. Oct 31, 2022, 06:15 ET

VANCOUVER, BC, Oct. 31, 2022 /CNW/ - GR Silver Mining Ltd. ("GR Silver Mining" or the "Company") (TSXV: GRSL) (OTCQB: GRSLF) (FRANKFURT: GPE) – is pleased to announce additional results from 38 infill drill holes in the resource update program underway at the Company's Plomosas Mine Area, Plomosas Project in Sinaloa, Mexico. These drill holes were targeted to replace historical holes used in the 2021 NI 43-101 mineral resource estimate, where unsampled intervals were assigned zero values, or to test new high-grade Ag-Au mineralized zones, identified by the Company in both the footwall and hanging wall of the main mineralized zone (Figure 1). GR Silver Mining's infill drilling program is continuing in the Plomosas Mine Area, and to date has added 105 holes (7,330 m) of new drilling inside the historic Plomosas Mine since completion of the Company's 2021 NI 43-101 mineral resource estimation.

  • The Plomosas Mine Area, which includes a historical mine with 7.4 km of underground development and related infrastructure, is providing positive drill results and new discoveries in many un-mined zones that will be incorporated into the Company's upcoming resource estimate. The updated NI 43-101 resource estimate will integrate the Company's two resource stage areas currently being drilled (San Marcial and Plomosas Mine Area) as well as additional drilling scheduled for La Colorada and the San Juan Area. GR Silver Mining will be the first company ever to integrate all exploration concessions at the resource stage into a single combined technical report, representing a major milestone in the Rosario Mining District.

    GR Silver Mining Chairman and CEO, Eric Zaunscherb comments "As designed, surgical infill drilling at Plomosas continues to demonstrate attractive polymetallic grades in the main hydrothermal breccia, where nil grades had previously been assigned for unsampled areas in the August 2021 resource block model. It is also very pleasing to see the potential addition of volume from the newly discovered footwall and hanging wall precious metal mineralization. Both may be impactful in the upcoming mineral resource estimate update anticipated in the first quarter of 2023."

    Plomosas Mine Area – Update Geological Modelling – Drilling Results to Date
    The 2022 infill drilling program, combined with detailed mapping and underground sampling, has now traced in detail the Ag-Au Pb-Zn hydrothermal breccia (partially mined by Grupo Mexico until 2001), as well as new mineralization associated with cross cutting faults. This new mineralization can be located on either the hanging wall or footwall of the main mineralized polymetallic hydrothermal breccia ("Plomosas Breccia") in the vicinity of major fault intersections, outlining wide zones with attractive Ag and Au grades close to existing underground development and or close to the surface (Figures 2 and 3).

    Historical mine production to 2001 was concentrated along the Plomosas Breccia, where lead and zinc values were the main target of historic underground bulk mining operations. The information collected by the Company during the past 12 months has indicated that not only are there remnant zones with well-preserved precious and base metal-rich hydrothermal breccias, but also well defined, wide Ag-Au only stockwork zones on the hanging wall and footwall of the Plomosas Breccia.

    The Company will continue the Plomosas drilling until December 2022, when all data will be integrated into an updated geological model for the Plomosas Mine Area. The updated mineral resource estimate is scheduled to be completed in the first quarter of 2023.

    Numbers may be rounded. Results are uncut and undiluted. True width not estimated as the Company does not have sufficient data from the new mineralized zones to determine the true widths of the drill hole intervals with any confidence. "na" = no significant result.

    * AgEq calculations using US$20.00/oz Ag, US$1,600/oz Au, US$0.90/lb Pb, US$1.10/lb Zn and US$3.00/lb Cu, with metallurgical recoveries of Ag – 74%, Au – 86%, Pb – 69%, Zn – 75% and Cu – 80%. AgEq = ((Ag grade x Ag Price x Ag recovery) + (Au grade x Au price x Au recovery) + (Pb grade x Pb price x Pb recovery) + (Zn grade x Zn price x Zn recovery) + (Cu grade x Cu price x Cu recovery))/(Ag price x Ag recovery) . ** PLI-22 37 interrupted and restarted as PLI 22-37A
