Aug 14, 2017 (A Wilson) - Bedrock, in general covered by deep over burden, is entirely Nipissing diabase; this overlies 50’ to 250’ of Cobalt Series sediments unconformable above Keewatin volcanics. The Keewatin Cobalt unconformity is intersected by the main shaft just below the 183’ level. The lower Nipissing diabase, Cobalt Series contact strikes east-west and dips 45ºS. The Columbus Fault strikes WNW. Silver producing veins occur essentially in Cobalt Series sediments with a north-west trending paleovalley on the Keewatin surface. The veins strike northeast and northwest to form a network. Keewatin interflow beds contain base metal sulphides over 14 ft. width.
