Aug 03, 2017 (A Wilson) - Cobalt Series and Keewatin rocks are traversed by two vertical faults, the Galena and No.6 that strike a little south of east and dip vertically. Silver and cobalt-bearing veins on the claim fall into two systems with connecting networks; on at the south end and one centrally in the claim. The veins mostly strike also a few degrees south of east and dip 80º to vertical. Midway between the system there are two parallel veins carrying fair ore. The productive part of the veins, with chalcopyrite, galena and sphalerite base metal mineralization, lies in Cobalt Series sediments directly above the folded interflow Keewatin sediments.
