Summa Silver Corp. announced that it has resumed exploration drilling at its high-grade Mogollon silver project near Silver City, New Mexico. Key Highlights: There's Unfinished Business at the Consolidated Mine: Exploration drilling has resumed around the historic Consolidated Mine, where mining was halted prematurely in 1942 by order of the federal government at the onset of World War II; There Are Important Unexplored Areas: The Consolidated Mine target represents only 1% of the total vein and structure strike length present on the project, which features numerous poorly explored to completely unexplored targets; Company Have a Fully Funded Program: A minimum of 11 holes and maximum of 25 holes will be drilled to test an area of 500m along strike by 350m up- and down-dip at a spacing between holes projected to support a potential mineral resource; Their Initial Results Are Significant: All 6 holes drilled to date by Summa Silver around the Consolidated Mine have intersected high-grade silver-gold mineralization.

Highlights include: 31.0 m at 448 g/t Ag equivalent* (129 g/t Ag, 3.88 g/t Au) in MOG22-051; 11.6 m at 429 g/t Ag equivalent* (220 g/t Ag, 2.70 g/t Au) in MOG21-042. The Limits of Mineralization Are Not Defined: The broad zone of mineralization at Consolidated is open in all directions. Drilling will continue to step-out to fully evaluate the size potential of the target area.

Drill Program: The Mogollon drill program is designed to test for un-mined extensions of the Consolidated Mine along- strike and down-dip centered on the north-striking Queen Vein. Results from the first 6 holes drilled by the Company have been reported (see March 3rd and May 3rd, 2022 news releases). All six holes intersected broad zones of epithermal-related alteration, veining and brecciation with locally strong concentrations of silver-gold-bearing sulfide mineralization.

Assay highlights from the first phase of drilling include 11.6 m at 429 g/t silver equivalent (220 g/t Ag, 2.70 g/t Au) in MOG22-04, located south of the Consolidated Mine and 31.0 m at 448 g/t silver equivalent (129 g/t Ag, 3.88 g/t Au) in MOG22-05 located north of the Consolidated Mine. The first is a step-out near MOG22-05. Subsequent holes will be systematic 50 to 100 m step-outs within a broader 500 x 350 m area along-strike and below the Consolidated Mine.

This target area only represents less than 1% of the total prospective vein and structure length on the property. All other prospective areas, including projected vein extensions on the newly acquired claims, remain largely under-explored.
