Work History
First staked as Caribou cl (12842) in Sep/19 by J. Fawcett, and explored with a 13.7 m adit in 1920 by Yukon Gold C under an option. Restaked by Fawcett as Caribou cl (16536) in Dec/24 and optioned by Treadwell Yukon CL, which explored with 40.2 m of drifting and mined 78.9 tonnes of ore in 1926-28.
Optioned in Jan/52 by United Keno Hill ML, which explored with a 8.2 m adit and bulldozer trenching in a new location to the southwest. The claim was taken to lease (Lot 926) in 1960 and was owned by R.L. Segsworth (40%) and E.H. Barker (60%) in 1968. The claim was purchased by Conwest in Sept/76.
Canada Tungsten Mg Corp L tied on BE cl (YA39081) to the east in Mar/79 and performed mapping and geochem sampling in 1979 and 1980. The lease was optioned to Dawson Eldorado ML in 1986.
Capsule Geology
The Treadwell adit on the north side of the claim is on an east trending longitudinal-type vein system while the United Keno adit, about 300 m to the southwest, appears to be on a transverse vein. Mineralization consists of minor galena, tetrahedrite and sphalerite. Both adits are caved.
Trenching by Dawson Eldorado in 1986 uncovered a 1.5 m wide vein containing lenses of mineralization assaying up to 8571.2 g/t Ag over 0.3 m. The ore mined in 1926-28 averaged 6102.7 g/t Ag and 70% Pb. Cantung located an unmineralized vein about 0.8 km to the south.
