Work History

Staked as U & V cl (84334) in Aug/65 by United Keno Hill ML following release of a GSC regional geochemical survey (Operation Keno). Explored by geological mapping, and geochemical surveys in 1965 and hand trenching in 1966.
Restaked as Nomad cl 1-32 (YB65205) by J.B. O'Neil and T. Woodall in Feb/96.

Capsule Geology

Two coincident lead and zinc anomalies were outlined in an area underlain by thick-bedded quartzite. Two grab samples from a narrow vein exposed by trenching assayed 445.7 g/t Ag and 7.7% Pb, and 445.7 g/t Ag and 0.2% Pb.
