Capsule

Work History

Staked as part of a large block of 321 BE cl (YA39081) in Mar/79 by Canada Tungsten Mg Corp L, which conducted mapping and geochem sampling in 1979-81. Restaked as Rebel cl 1-14 (YB42568) in March/94 by J.B. O'Neil. Restaked in Mar/95 as Ml cl 1-12 (YB44007) by R. Wondga and R. Mueller.

Capsule Geology

Three veins cut the Mississippian Keno Hill Quartzite. Two are minor quartz stockworks with disseminated galena from which a selected specimen assayed up to 490 g/t Ag. The third is a quartz vein containing minor disseminated arsenopyrite within a 5 m long stockwork. A selected specimen assayed 31.5 g/t Au and 194 g/t Ag.
