Jul 28, 2017 (A Wilson) - The Nipissing diabase sill, about 1000 ft. thick, intruded the Keewatin rocks; its upper contact strikes NNW and dips about 18º ENE. It is cut by the northwest trending Cross Lake diabase dike. The property is crossed by two major faults; the Cross Lake Fault that strikes northwest and lies in the northeast portion of of the claim; and the O’Brien-Violet Fault that strikes WNW with vertical dip and is exposed on 150 ft. level of the Lake Shaft. Two other parallel minor faults occur. The host rocks for the set of NW-striking veins are both diabase and Keewatin sediments. Veins No. 1 and 2 were the most important producers. The silver-cobalt produced was restricted to the proximity of the Upper diabase contact. An appreciable amount of pyrrhotite, pyrite and chalcopyrite mineralization occur in the Keewatin sediments below the diabase contact.
