Work History
Discovered during road construction and stated as Usacan & Canusa cl (4352) in Feb and Jun/45 by N. Robert and U.J. Arsenault for Cominco, which trenched later in the year. Restaked as SK cl (70973) in Aug/55; Galena cl (77870) in Aug/62 by R. Kirk & Assoc; and Bird cl (98614) in Jan/66.
Restaked as JN cl (Y12213) by P. Poggenburg in Mar/67, and optioned in June to Silver Chief Mls L. Silver Chief conducted an EM-16 survey, staked additional JN cl (Y24301) in Mar-Apr/68 and did more geophysical surveys in 1969.
Restaked as RN cl (Y67385) in Oct/72 by R. Smith and in Oct/76 as Canol cl (YA8402) by W. Shiftlet.
Capsule Geology
Galena and pyrite occur in 1 m quartz veins which cut shale and schist of Cambrian age. A chip sample across 0.9 m assayed 5.2% Pb, 44.5 g/t Ag and 0.3 g/t Au. In 1968, chip samples across the No. 2 Vein Zone returned 330 g/t Ag across 3.4 m from a quartz vein cutting dolomite, and 394 g/t Ag across 4 m of black gouge in the vein fault.
The No. 3 Vein Zone consists of a 14 by 0.5 m massive galena vein in a fault zone 2 to 3 m wide and at least 35 m long. The zone strikes 170° and dips 65°W. Specimens of massive galena averaged 2225 g/t Ag and 75% Pb. Up to 14% Zn occurs in adjacent fractured wallrocks.
