Lithology Comments

Aug 03, 2017 (A Wilson) - Nipissing diabase outcrops on surface and Keewatin rocks are exposed in the underground workings. The diabase bottom contact dips 25º S. A WNW-striking 85º NNE-dipping fault cuts the diabase on the 310 ft. level. Silver-bearing veins have been found in diabase as well as in Keewatin cherty sedimentary rocks, which latter contain pyrite, sphalerite, galena,and chalcopyrite. Vein 1-S, perhaps the most important, bifurcates at the Conisil shaft, with one branch striking north and the other east.

Mineralization Comments

Jul 24, 2017 (A Wilson) - The most important vein found to date on the property is the No.1-S, which is directly continuous from the Lawson claim. From the Lawson boundary to the vicinity of the Gonisil shaft the strike is N. and the dip nearly vertical in the Nipissing diabase and about 60OE. in the Keewatin. The vein on the 460-foot level is about 15 feet from the shaft. Easterly from the shaft the vein bends and takes on an irregular eastward strike and a nearly vertical dip. On the Conisil property the vein has been followed by drifts on the 300-foot and 400-foot Lawson No.8 shaft levels and by the 460- foot Conisil shaft level. The vein is presently being explored and mined. Production to-date has been obtained very largely from where the vein traverses Keewatin rocks. The vein which at surface passes through the Conisi shaft has an irregular strike of approximately N.70°E. a and a nearly vertical dip. In the adit from which the Conisil shaft was started, cobalt mineralization in small amount accompanies the vein. In the vicinity of the shaft five adits have been made along small calcite veins with strikes about N70E and nearly vertical dips. In at least the vein in Adit No.2 (150 feet south of the shaft) cobalt mineralization is present).
