Aug 04, 2017 (A Wilson) - Keewatin volcanics outcrop in the west part of claim and are steeply folded with west-northwest strike; these are overlain in the east part by Cobalt sedimentary rocks that strike north and dip east, Nipissing diabase occurs further east beyond the claim and presumably, formerly overlay the Keewatin and Cobalt rocks. A swarm of veins that strike northeast occurs only in the cobalt rocks above the Keewatin; these veins contain silver and cobalt. Two veins, no.105 and 141, that occur in the Keewatin formation and strike west-northwest parallel to it bedding were rich in cobalt with little silver. Veins with silver and cobalt mineralization strike northeast and are several hundred feet in length; they occur in a zone 3000 ft. long that strikes north.
