Summa Silver Corp. announced the discovery of a new high-grade vein zone in final assay results from the recently completed drill program at the Hughes Project in Nevada. In addition, the Company has commenced its drill program at the Mogollon Project in New Mexico.

Approximately 2,000 meters of drilling is planned across three new targets along the Queen Vein at the Mogollon Project. Hughes Project Discovery Highlights. 392 g/t AgEq over 3.0 m (3.04 g/t Au, 147 g/t Ag) in a newly discovered vein-zone approximately 650 m east of the Ruby zones in hole SUM23-60.

Eastern Extension of the Tonopah Mining District: Three new discoveries were made in 2023 between 1.5 km and 4.7 km along strike from the historic Tonopah mining district. New Zones Open for Expansion: All new zones are open in all directions and require step-out drilling over a total trend length of 6.5 km. Mogollon Project Drill Program Highlights.

High Potential Targets: Drill holes have been designed to test targets immediately below and along strike from zones of shallow high-grade mineralization. Size and Scale on the Queen Vein: All holes will represent significant step outs along a strike length of nearly 2 km on the Queen vein. Drilling Highlights from the Queen Vein.

MOG22-05: 448 g/t AgEq over 31 m (129 g/t Ag, 3.88 g/t Au) o MOG22-10: 640 g/t AgEq®? over 9.9 m (306 g/t Ag, 4.26 g/t Au). Completed Hughes Drill Program.

The recently completed exploration drill program at Hughes Project consisted of reverse circulation ("RC") and diamond drilling across five previously undrilled epithermal vein targets, all located east and northeast of the historic Tonopah mining District. The purpose of the reconnaissance-style drill program was to test for epithermal-related veins and vein-sets along trend to the east from the Ruby discovery and to define the eastern extension of the district. Three new vein discoveries have so far been made.

Further drilling across the un-constrained Ruby area is warranted to define the structural controls and mineralization potential of the area. Further drilling across the un -constrained Ruby area is appropriate to define the structural controls and Mineralization potential of the area. Commencement of Mogollon Drill Program.

The Mogollon drill program is designed to systematically test the high-grade mineralization potential of new targets located along the Queen vein. The winter drill program will now consist of significant step out holes along a ~2 km strike length, south of the Consolidated target. Three targets have been prioritised and are proximal to historic, small-scale underground mines where mineralization is open for expansion.

Drill core and RC chip samples were sent to Paragon Geochemical Laboratories in Sparks, Nevada for preparation and analysis. Paragon meets all requirements of the International Accreditation and analysis.
