GR Silver Mining announced high-grade silver results from underground infill drilling at the Plomosas Project in Sinaloa, Mexico. The results support what the company sees as great potential to increase silver grades found in the mine.
The drilling was targeted at silver mineralization in the upper levels of the project’s underground works, in areas where unsampled intervals from historical drill programs within the 2021 resource block model were previously thought to be void of mineralization.
“The 2022 infill drill program at the Plomosas Mine has been carefully designed to address upside potential in the resource block model. 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,” said Eric Zaunscherb, CEO and Chairman, GR Silver Mining.
GR Silver informed that the combination of systematic underground mapping, 3D modeling of different styles of mineralization and underground infill drilling at the historic Plomosas Mine identified the attractive, wide and high-grade mineralized zones containing both gold and silver.
The underground drilling program started in March of 2022 and continues as of May 26. The drill holes are predominantly short in length and planned to point at zones where the recent geological mapping identified opportunities to upgrade the model of mineral resources of, using underground developments to gain acccess.
“Furthermore, it is very encouraging to see such high-grade results confirming the existence of new, high-grade silver 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,” added the CEO.
In addition, the company pointed out that 13 promising underground drill holes have been completed as of today.
GR Silver Mining is a Canada-based, Mexico-focused junior mineral exploration company engaged in cost-effective silver-gold resource expansion on its fully-owned assets, which are located on the eastern edge of the Rosario Mining District in the southeast of Sinaloa. GR Silver Mining controls two past-producing precious metal underground and open-pit mines within the Plomosas Project, which includes the integrated San Marcial Area and La Trinidad acquisitions. In conjunction with a portfolio of early to advanced-stage exploration targets, the company holds 734 km² of concessions containing several structural corridors totaling over 75km in strike length.
