Intersects 1,133 g/t silver equivalent* over 1.65 m in untested vein 200 m below the Eberle Mine
Vancouver, April 23, 2024 – Summa Silver Corp. (“Summa” or the “Company”) (TSXV:SSVR) (OTCQX: SSVRF) (Frankfurt:48X) is pleased to provide assay results from its final two drill holes completed during the winter drill program at the high-grade silver-gold Mogollon Project, New Mexico (the “Mogollon Project”).

Key Highlights
Aggressive Step-Out Below the Eberle Mine: Strong mineralization was intersected 200 m below the Eberle Mine
1,133 g/t silver equivalent* (693 g/t Ag, 8.8 g/t Au) over 1.65 m from 482.5 m down hole (170 m vertical depth) in hole MOG23-21.
New Vein-Splay Drilled: This intersection is from a previously undrilled splay of the Queen Vein and opens new exploration potential into areas east of the main strand of vein.

Size and Scale: This drill program successfully showed that strong mineralization exists along at least 2 km of the Queen Vein system.

Additional Upside: Systematic follow up drilling is required on the Queen Vein and beyond which is expected to delineate significant zones of high-grade mineralization (see attached figures).
*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)).
