Aug 01, 2017 (A Wilson) - Keewatin sediments cut by a Haileyburian lamprophyre dike are overlain by Cobalt sediments. The northwest trending Cross -Lake olivine diabase dike crosses the northeast striking parallel faults. Several cobalt-bearing veins with little silver, chalcopyrite, galena and sphalerite occur in the Keewatin sediments. The No. 2 shaft vein, striking ENE with subvertical SSE dip, contained in a trench east of the shaft pockets of massive cobalt with nickel and cobalt mineralization
