Capsule

Work History

This showing was discovered by the GSC in 1965. It was staked as Lee cl (Y19118) in Aug/67 by Spartan EL and restaked as Mung and Tung cl (YA33709) in Jul/78 by Cominco L. This area was prospected in 1977 and 1978 by Welcome North ML's Basin Project.

Capsule Geology

Minor amounts of chalcopyrite and scheelite occur in a shear zone cutting Proterozoic Hyland Group clastic rocks. To the southeast, scheelite and pyrrhotite occur in skarn layers up to 3.5 m thick, which formed from limy beds at the contact of a small Cretaceous pluton.
