Jul 26, 2017 (A Wilson) - Nipissing diabase occurs as a N-S trending arch 245 ft. thick overlying flat Cobalt Series sediments. The Cobalt Series consist of 195 ft. of conglomerate overlain by 35 ft. of greywacke. The lower contact of the Cobalt Series lies in a paleovalley on the Keewatin surface as seen in an E-W cross-section through the shaft. The Keewatin rocks consist of steeply dipping E-W trending volcanics and sediments. No 10 vein-fault from the adjoin Cross Lake O’Brien property extends into claim 654 in an east-southeast direction north of the shaft. The North and South veins also follow ESE faults cutting all three major rock units. Veins were the most productive in the Keewatin rocks.

Jul 26, 2017 (A Wilson) - In 1935 a very small production of cobalt was obtained; 9570 lbs. of cobalt were shipped. Total production 1939-1940 was 457 lbs of cobalt. Some four veins, striking easterly or a little south of east, were discovered on the 400-foot level; of these two, which the writer designates as the North and the South vein contained cobalt and nickel but apparently negligible amounts of silver. On Map P.97 the writer shows the vertical projection of these two veins to surface. The vein structures are said to be well marked faults. The South vein is not a simple one; followed 20 feet at N.65ºW from where discovered traversing Cobalt Series conglomerate in the 400-foot level cross-cut it divides into two branches, the less important one continuing along the original strike and the more important one striking S75 W This latter was drifted on for some 80 feet at which point another irregularity and vein junction was encountered. At this vein junction a winze was put down to the 452-foot level and on this a few feet of drifting was done. The total footage of drifting on the vein was less than 300 feet; this was done in the vicinity of the Cobalt series-Keewatin contact, both above and below it. The Cobalt series over Keewatin contact on the 400-foot level at the vein lies about 50 feet east of the Cross Lake O'Brien-Smith Cobalt line. The North vein carried quite minor amounts of cobalt where in Cobalt Series conglomerate. On the 452-foot level,
