Capsule
Work History
Staked as Tin cl (YA10883) in Nov/77 by Union Carbide Can ML, which explored with airborne and ground radiometric surveys in 1977 and mapping, sampling and ground and airborne surveys in 1978.
Capsule Geology
The claims are underlain by dolomite of the Cambro-Ordovician Jones Ridge Formation, which is cut by narrow diabase dikes. Two units have been mapped, an upper cherty laminated dolomite and a lower, massive, partly brecciated dolomite. The upper sequence contains erratic intraformational breccias which weather rusty. These breccias contain phosphate minerals and uranium on the Casca claims, 3.2 km to the west in Alaska, but none were found on this property. Ten airborne radiometric anomalies found in 1977 were not confirmed by the 1988 work.
