Additional Vein Zones In Step-Out Holes At The Mogollon Project

VANCOUVER - Summa Silver Corp. reported on the high-grade silver-gold Mogollon Project, near Silver City, New Mexico. Four more holes have intersected the Queen Vein marked by intermittent to continuous quartz-carbonate veins and breccias between 3 and 61 meters in core length featuring local zones of silver-bearing sulfides. The Queen Vein zone intersections to date average 66% mineralized where assays have been received and as defined by samples exceeding 100 g/t AgEq. Drilling focused on expansion around the historic Consolidated Mine has intersected visible silver sulfide mineralization where MOG23-16 is a 100m step-out and MOG23-19 is a 175 m step-out from holes previously drilled by the Company. The mineralized high-grade zones remain open in multiple directions and collectively cover a strike length of 500m.

Assays are pending for 8 holes and drilling at the Mogollon Project is now complete for the season. Multiple additional targets are being developed at the Mogollon Project as the Company advances extensive 3D geological modeling efforts.

Galen McNamara, CEO, said, "Step-out drilling at the Mogollon Project has proven that substantial concentrations of high-grade silver and gold remain in this historic American district. With zones largely open to continued expansion, we look forward to resuming drilling here in the fall. Additionally, extensive 3D geological modeling has revealed multiple additional targets which will demand drill testing."
