Aug 11, 2017 (A Wilson) - The veins traverse Cobalt Series sediments and also Nipissing diabase. Although no one vein has been traced from the sediments into the diabase it seems probable that direct continuations occur. The strikes are N.70ºE.; in the sediments the dips are vertical but in the diabase about 75º to the north. The vein structures are fractured zones; the gangue is of quartz and calcite; chalcopyrite, in widths up to 2 1/2 inches, and a little pyrite were seen. The veins have been explored to a depth of a few feet only. At 900 feet south and 150 feet east of northeast corner of the claim and at the west edge of the swamp, the Cobalt conglomerate is whitened and recrystallized and contains irregular areas of quartz with a little chalcopyrite, pyrite, magnetite and hematite.
