Exploration History

1907-1920: Beaver Consolidated Mines Ltd. – No. 1 Shaft sunk to1600 ft.; No. 2 shaft sunk to 77 ft., Knight reports that some 8½ miles of underground workings were done; 1912: concentrating plant installed. 1907-1920: exploration of the top surface of the Nipissing diabase;1916-17 exploration of the bottom of the Nipissing diabase. 1924-29: mine inactive. 1929-1940: small production was won yearly from yearly operations. 1944: Silanco Mining and Smelting Co. had ownership. 1957: Ansil Mines Ltd. had ownership. 1967: Leased to Agnico Mines Ltd. From 1943 to 1959 mining was carried out in conjunction with Temiskaming Mine (Beaver and Temisakaming mine interconnected underground). 1989: Production at Beaver-Temiskaming Mine ceased.

Lithology Comments

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.

Mineralization Comments

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.
