Aug 01, 2017 (A Wilson) - Three veins named after the shafts, traverse the Cobalt Series and Keewatin rocks. The south shaft vein, essentially cobalt bearing with minor silver, follows a northerly striking and 75ºE dipping fault at the contact between conglomerate to the east and Keewatin lavas to the west. The pit south of the shaft on this vein and fault exposes cobalt and galena. The North shaft vein on the 106 ft. level where it traverses deformed Keewatin sediments is made up of calcite, pyrite and chalcopyrite. The Middle-shaft calcite vein strikes east and follows sedimentary bands.
