Summa Silver Corp. announces high-grade silver and gold drill results from the Mogollon Property near Silver City, New Mexico. The focus of the Mogollon drill program is testing un-mined extensions of the Consolidated Mine, centered on the north-trending, epithermal-related Queen Vein.

Holes MOG22-05 and -06, targeted vein-hosted mineralization along strike to the north and down-plunge to the south from the Consolidated Mine stopes. Both holes intersected broad zones (up to 31 m) of epithermal-related alteration, veining and brecciation with locally strong concentrations of silver-gold sulfide mineralization. These results continue to demonstrate the high-grade nature of the Queen Vein and also the strong grade continuity along the vein and within the complex broad vein system.

Hole MOG22-05 intersected 459 g/t silver equivalent (AgEq) over 31 m from 291 m down hole including higher grade sub-intervals of 1,903 g/t AgEq over 1.8 m including 6,311 g/t AgEq over 0.5 m from 291 m down hole and 1,223 g/t AgEq over 2 m from 319 m down-hole. The thickness of this high-grade zone confirms the substantial strength of the epithermal-related mineralizing system surrounding the Consolidated Mine. Hole MOG22-06 intersected 200 g/t AgEq over 10.4 m from 358.1 m down hole.

This is the deepest hole testing the extensions of the Consolidated Mine drilled by the Company to date. It confirms a depth extent of mineralization beginning at surface, as marked by the presence of historic stopes, and continuing to a depth of at least 425 m where it remains open to continued expansion. Using cumulative grade thickness as a proxy for the tenure of mineralization and also for modelling the presence of plunging high-grade shoots, these holes continue to confirm the considerable exploration potential along-strike and down-dip surrounding the Consolidated Mine.

The Queen Vein system consists of a hanging wall of silicified and brecciated andesite and rhyolite cut by zones of colloform-banded chalcedonic quartz veins increasing in frequency with depth towards the Queen Vein. The Queen Vein is highly-complex with strong textural evidence for multiple epithermal-related fluid events that formed calcite + quartz veins, quartz-rich breccias with bladed quartz, colloform banding, and local silver and gold -bearing sulfides. The footwall to the Queen Vein system consists of intensely silicified and brecciated andesite with locally abundant silver and gold -bearing sulfides as disseminations and banded within chalcedony-rich veins.

Drill holes on 50 to 100 m centers are designed to systematically test the lateral and vertical continuity of mineralization over a strike-length of approximately 500 m and near-vertical, down-dip extent of over 300 m beginning at approximately 130 m below surface.
