Southern Silver Exploration Corp. (TSX.V:SSV) (“Southern”) reports that Kirkham Geosystems Ltd. has completed an update of its independent Mineral Resource Estimate (“MRE”) on the Cerro Las Minitas project in Durango State, Mexico. The updated MRE significantly expands sulphide resources in the La Bocona deposit through the incorporation of the North Felsite zone into the resource model. The revised estimate utilizes the same metal pricing and metallurgical recoveries as the previous 2021 MRE, utilizes a Net Smelter Return (“NSR”) cut-off, as detailed in Table 1, and reports average grades on a AgEq, ZnEq and $US/t NSR basis. The Mineral Resource estimates for the South Skarn, Blind-El Sol Skarn Front and Las Victorias deposits and the small oxide resource initially estimated in 2021, remains unchanged in this current update.
