Work History

Staked as Tyr cl (Y63849) in Oct/71 by Can Occidental Pet L, which conducted soil sampling and mapping in 1972 and added more Tyr cl (Y67091) to the north in Aug/72.

Capsule Geology

Minor zones of chalcopyrite and molybdenite occur in a skarn-hornfels zone about 300 m across that has developed in metasedimentary rocks near the contact of felsic volcanic flows, tuff and breccia.
