Visible Mineralization In First Hole At Mogollon

VANCOUVER - Summa Silver Corp. reported on the continuing drilling at the high-grade silver-gold Mogollon Property, near Silver City, New Mexico. Galen McNamara, CEO, said, "Although we don't expect the entire intersection to carry grade, the wide zone of classic low-sulfidation veining in our first hole attests to the prospectively of the Queen Vein and the significance of the mineralizing system in general. This hole confirms our modeling of historic mine records and limited exploration drilling of the target. It also supports the strong potential of the vein along strike and down-dip."

The focus of the ongoing drill program is testing un-mined extensions of the Consolidated Mine, centered on the north-trending, epithermal-related Queen Vein (see October 15th, 2021 News Release). Holes on 100-meter centers are designed to systematically test the lateral and vertical continuity of mineralization over a strike-length of approximately 500 meters and near-vertical, down-dip extent of over 250 meters beginning at approximately 130 meters below surface.

The first hole (MOG21-01, drilled to 440 meters) targeted the extension of structurally-controlled, vein-hosted mineralization south of the historic Consolidated stopes. A broad 50-meter zone of epithermal-related alteration, veining, brecciation and mineralization, cored by the Queen Vein, was intersected at approximately 280 meters down hole. Within this zone, the hanging wall to the Queen Vein consisted of silicified and brecciated andesite and rhyolite cut by zones of colloform-banded chalcedonic quartz veins increasing in frequency with depth towards to the Queen Vein. The 8 meter wide Queen Vein at approximately 296 meters down hole comprised calcite + quartz veins, quartz-rich breccias with bladed quartz, colloform banding and local silver-bearing sulfides. The footwall to the Queen Vein consists of intensely silicified and brecciated andesite with abundant silver-bearing sulfides as disseminations and banded within chalcedony-rich veins.
