Summa Silver Corp. announced that it has commenced drilling at the high-grade silver and gold Mogollon Property, New Mexico. The focus for drilling at Mogollon is testing un-mined extensions of the Consolidated Mine, centred on the north-trending, epithermal-related Queen Vein. The initial set of drill holes are designed to intersect the Queen Vein on approximately 100-meter centers. This drill pattern will 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. Over 5,000 total meters are scheduled for this phase of drilling with an additional minimum of 10,000 meters planned for the first half of 2022 as drill hole spacings are tightened to approximately 50 meters. The north-striking Queen Vein is hosted along the Queen Fault which has been traced for over 5 kilometers at surface. The fault steeply dips to the east with a normal sense of displacement (east-side down) that juxtaposes younger andesitic volcanic and volcaniclastic rocks to the east with dominantly rhyolitic rocks to the west. Vein-hosted mineralization along trend from the Consolidated Mine has only been historically tested by eight drill holes. All drill holes, collared in the hanging wall to the east and drilled to the west, intersected zones argillic alteration cored by quartz-rich stringers, stockworks and breccias peripheral the argentite-bearing, quartz-calcite dominant Queen Vein. Broad zones of vein- hosted silver and gold mineralization together with higher-grade cores were interested in most holes (e.g., 598 g/t silver equivalent over 14.0 m in MGR-38, 805 g/t silver equivalent over 4.0 m in MGR-14, and 1,127 g/t silver equivalent over 2.7 m in MGR-35*3). These data suggest vein-hosted mineralization persists over significant distances along the vein and that mineralization is open in multiple directions. The focus of the 2021 fall drill program is to verify and build on these historic drill results and to confirm mineralization continuity.
