GR Silver Mining Ltd. (TSXV: GRSL) (OTCQB: GRSLF) has obtained high-grade silver (Ag) results from underground infill drilling at the Plomosas Project in Sinaloa State, Mexico.
The results continue to support the potential to increase Ag grades in the Plomosas Mine Area resource. The drilling targeted high grade Ag mineralisation in the upper levels of the underground workings, in areas where unsampled intervals from historical drill holes within the 2021 resource block model were previously assigned zero values.
Highlights:
- Core drilling, in un-mined shallow areas (up to 160 m below surface) of the historical Plomosas Mine, continues to define attractive wide and high-grade Ag mineralisation.
- Presence of high-grade results with predominance of Ag mineralisation only in areas with potential to increase Ag grade in planned update of resource model, including:
- PLIP22-013: 6.5 m at 1,458 g/t Ag (1,485 g/t AgEq), including
0.9 m at 3,118 g/t Ag (3,266 g/t AgEq) - PLIP22-012: 14.0 m at 146 g/t Ag, including
0.4 m at 2,474 g/t Ag (2,542 g/t AgEq) - PLIP22-011: 2.9 m at 190 g/t Ag, including
0.4 m at 626 g/t Ag - PLIP22-010: 8.3 m at 100 g/t Ag
- PLIP22-013: 6.5 m at 1,458 g/t Ag (1,485 g/t AgEq), including
- Ag mineralisation on the hanging wall of the main polymetallic Plomosas Breccia, in the upper levels of the underground workings, supports the upside potential for Ag grades in the mineral resource update scheduled for Q1|23.
- The combination of systematic underground mapping, 3D modelling of different styles of mineralisation and underground infill drilling at the historic Plomosas Mine has defined attractive, wide, high-grade gold-silver (Au-Ag) mineralised zones. These new zones will be incorporated into the upcoming mineral resource block model and estimation.
- Recent Ag drill results provide encouragement for the company to continue drilling underground at the Plomosas Mine Area in 2022 with the objective of significantly increasing the Ag grade in areas of the resource model.
“The 2022 infill drill programme at the Plomosas Mine has been carefully designed to address upside potential in the resource block model,” Chairman and CEO, Eric Zaunscherb, said.
“It has been our thesis that historical sampling lacked detail in some unmined areas resulting in the adoption of zero grade in unsampled drill hole intervals in the current resource model. This is supported by the observation that current resource model grades in areas already mined are lower than suggested by historical production grades.
“Further, it is very encouraging to see such high-grade Ag results confirming the existence of new, high-grade Ag zones associated with previously ignored cross-cutting structures. It is highly satisfying to see further proof of concept on both themes, with the potential for a commensurate re-rating.”
