Jul 28, 2017 (A Wilson) - ) Keewatin volcanics are intruded by 1100 ft. thick Nipissing sill with east dip that steepens along north-striking roll. The sill encloses a large xenolith of Lorrain Granite. The Beaver Fault, with steep east dip was initiated by the granite intrusion. Most silver and cobalt production was obtained from veins No. 3 and 5 in Keewatin rocks near contact above sill, a little in the sill and some in the granite xenolith. Some production below the sill was obtained in Keewatin rocks from vein 1600-1.

Jul 28, 2017 (A Wilson) - Production was obtained mainly from two veins, Nos. 3 and 5 which are part of the same vein group or "system" of the Temiskaming mine to the south. The present writer would emphasize that the veins in this system were greatly influenced by older pre-diabase structures. Older quartz veins are commonly followed by younger silver-cobalt-calcite veins. There is no suggestion that the position of these older structures was influenced to any extent by the Keewatin chert bed.
