In This Article:

Hughes Project in situ Mineral Resources
Indicated: 10.47 Moz AgEq at 332 g/t AgEq contained in 0.98 Mt
Inferred: 33.42 Moz AgEq at 418 g/t AgEq contained in 2.49 Mt

Hughes Project Tailings Mineral Resources
Inferred: 2.74 Moz AgEq at 68 g/t AgEq contained in 1.26 Mt

Mogollon Project Mineral Resources
Inferred: 32.08 Moz AgEq at 367 g/t AgEq contained in 2.72 Mt

Vancouver, British Columbia--(Newsfile Corp. - January 16, 2025) - Summa Silver Corp. (TSXV: SSVR) (OTCQX: SSVRF) (FSE: 48X) ("Summa" or the "Company") is pleased to report inaugural mineral resource estimates (each an "MRE") for the Company's 100% owned projects in the United States - the Hughes Project in Nevada ("Hughes Project") and the Mogollon Project in New Mexico ("Mogollon Project").

Hughes Project:

  • Indicated Mineral Resources (in-situ) are estimated to include 10.47 million silver equivalent ounces(1) (Moz AgEq) (5.94 Moz silver and 0.05 Moz gold) at a grade of 332 grams per tonne silver equivalent(1) (g/t AgEq) (188.0 g/t silver and 1.59 g/t gold) contained within 0.98 million tonnes (Mt).

  • Inferred Mineral Resources (in-situ) are estimated to include 33.42 Moz AgEq (16.2 Moz silver and 0.19 Moz gold) at a grade of 418 g/t AgEq (202.7 g/t silver and 2.38 g/t gold) contained within 2.49 Mt.

  • Inferred Mineral Resources in Tailings are estimated to include 2.74 Moz AgEq (1.79 Moz silver and 0.011 Moz gold) at a grade of 68 g/t AgEq (44.0 g/t silver and 0.26 g/t gold) contained within 1.26 Mt.

Mogollon Project:

  • Inferred Mineral Resources are estimated to include 32.08 Moz AgEq (12.12 Moz silver and 0.24 Moz gold) at a grade of 367 g/t AgEq (139 g/t silver and 2.72 g/t gold) contained within 2.72 Mt.

Key Highlights:

  • Clear Additional Upside at the Hughes Project: The mineralized zones remain open to expansion and the project includes the mostly unexplored 4 km eastern extension of the prolific Tonopah Mining District which is reported to have produced 175 Moz of silver and 1.86 Moz of gold at 679 g/t Ag and 7.3 g/t Au, respectively, along its original 4 km mined strike length (REF1).

  • Step-Out Drilling is Underway at the Hughes Project: A fully funded drill program designed to both expand the known mineralized zones and explore for new veins on the eastern extension of the Tonopah mining district in currently underway at the Hughes Project.

  • Step-Out Drilling has Intersected the Planned Target Horizons: The first drill hole, an 85 m step-out at the Ruby Zone, has intersected zones of epithermal-related quartz veins and breccias locally featuring visible silver-sulfide mineralization.
