High-Potential Targets And Additional Plans For Resource-Style Drill Program At Mogollon Project

VANCOUVER - Summa Silver Corp. reported on the drill planning for the Mogollon Project, New Mexico. Known High-grade Mineralization - All targets along the Queen vein have previously been de-risked by reconnaissance-style and step-out drilling, highlighted by: 1) 448 g/t AgEq* (129 g/t Ag, 3.88 g/t Au) over 31 m (Consolidated, MOG22-05). 2) 640 g/t AgEq (306 g/t Ag, 4.26 g/t Au) over 9.9 m (Consolidated, MOG22-10). 3) 433 g/t AgEq (134 g/t Ag, 3.66 g/t Au) over 23.2 m (Consolidated, MOG22-16). 4) 1,133 g/t AgEq (693 g/t Ag, 8.8 g/t Au) over 1.65 m (Eberle, MOG23-21). 5) 393 g/t AgEq (64 g/t Ag, 3.9 g/t Au) over 7.4 m (South Queen, MOG23-20).

Strong Recoveries for Gold and Silver: Two previously reported representative composite vein samples from Consolidated returned recoveries ranging from 96.2% to 97.9% for silver and 97.7% to 97.8% for gold from flotation concentrates. All Targets are Open for Expansion: All mineralized zones along the Queen vein are open for expansion and require step-out drilling to fully evaluate grade and scale potential. Systematic Drilling Planned: Data from infill and step-out drilling at key targets will be used to fully investigate grade continuity along-strike and down-dip to facilitate future mineral resource estimations.

*Silver equivalent is calculated using US$20/oz Ag, US$1,800/oz Au with metallurgical recoveries of Ag - 90%, Au - 95%. AgEq = (Ag grade x Ag recovery)+((Au grade x Au recovery) x (Au price / Ag price)).

Galen McNamara, CEO, stated: "Our work at Mogollon has shown that the Queen vein is extensively mineralized with high-grade silver and gold in multiple zones across more than 2 km. Systematic drilling is now required to quantify ounces in a step-by-step manner as targets are drilled and developed throughout the district in the coming months and years. With 77 km of vein and prospective structure present on the project, we are confident in big-picture ounce potential here and look forward to continuing to unlock value in this storied American silver district."
