GR Silver Mining Ltd. announced that it aims to confirm the presence of wide silver mineralization close to the surface along the target contact. Highlights from the latest drilling at San Marcial (down-hole thickness): SMS23-05: 20.2 m at 187 g/t Ag, including 5.7 m at 513 g/t Ag and 0.8 m at 2041 g/t Ag. The SMS23-05 result continues to suggest an extension of the Mineral Resource along strike and down-dip in the SE Area Discovery Zone, San Marcial Area.

The result also reflect an increase in grade at some specific elevations when comparing these results with the previously released result SMS23-04. From the original 300 m strike length of the SE Area Discovery that was incorporated into the Mineral Resource, the Company has drilled and identified an additional 250 m of wide shallow silver mineralization along the prospective Target Contact. The advance in the understanding of the controls on mineralization, post successful drilling and discovery of the SE Area, provided essential exploration tools to achieve the increase in the footprint of the mineralization along the strike.

An excellent drill intersection hit rate has demonstrated the efficacy of the Company's geological exploratory model as the SE Area Discovery mineralization is being extended along the Target Contact. Surface Ag lithogeochemical anomalies and intriguing geophysical anomalies do appear to provide attractive targets for mineralization below the surface. Recognition of higher-grade mineralization at specific elevations within the mineralizing system has important implications for the overall average grade.

Further, newly recognized subtle changes to alteration and mineralization styles appear to be associated with the intrusive body or bodies that may have provided the energy and metalliferous fluids to the Target Contact system, providing a new and exciting avenue for exploration. GR Silver Mining has completed five drill holes in the first program to be undertaken outside of the SE boundary of the Mineral Resource, which includes the initial extension of the SE Area discovery. This drill hole is also defining an extension of the mineralized zone for at least 400 metres along the strike to the SE from discovery hole SMS22-10 (Discovery drill hole SE Area).

The results to date of drilling along the contact zone between the lower volcano-sedimentary unit and upper volcanic continue to the SE and SMS23-05 support continuity of high-grade silver mineralization along or very close to the contact zone (SMS23-05 5.7 m @ 513 g/t Ag including 0.8 m @ 2041 g/t Ag). The success of the step-out drilling program with high-grade results confirming down plunge continuity of the mineralization supports the existing potential to increase resources at the San Marcial Area.
