Kootenay Silver Inc. reported the discovery of a potential new high-grade zone known as the East Block within the Columba Silver Project, located in Chihuahua State, Mexico. During expansion drilling east of the JZ Zone as part of the 2021 phase 3 drill program, Hole CDH-21-101 returned results indicative of high-grade areas on the Property seen in the F, B and D Veins and JZ zone. Phase 3 drilling is complete with 12 holes from the JZ Trap area, B and D Veins that remain to be reported. Further results will be released once final assays are received. Drill Highlights to Hole CDH-21-101: 459 gpt silver over 1.6 meters including: 1,190 gpt silver over 0.5 meters and 127 gpt silver over 1.1 meters. Mapping by Kootenay's geological team recognized that the Columba vein system continues further east across a fault which puts the system slightly deeper than previously considered. Five holes were drilled into this block to see if the narrow structures at surface with weak silver content contained significant quartz veining with grade deeper down. This is a pattern associated with several other veins found throughout the property. The deeper of the five holes hit high grade silver over 1,000 gpt indicating the East Block follows the mineral pattern confirmed elsewhere on the property where silver grades improve with depth. Four of the five drill holes hit silver mineralization, indicating good potential for expanding the size of the high-grade East Block area at Columba. Mapping showed a strike extension of 350 to 500 meters in four different parallel structures. Additional drilling is required in the East Block to confirm the presence of a high-grade deposit. However, there is opportunity to significantly expand the size of the Project's impressive potential in a new and previously untouched area.
