Capsule

Work History

Staked as Richard cl (Y42542) in Aug/7O by R. Bourget. Restaked as King cl (YA45379) in Nov/79 by A. Black, and geochem sampled in 1980 by a joint venture between Cyprus Anvil and Hudson's Bay O & G, and by A. Black in 1981. In 1981, A. Black and T. Liverton conducted detailed geochem surveys and minor hand trenching.

Capsule Geology

The property covers a contact between Late Proterozoic and Early Paleozoic pelitic schist and calc-silicate rocks intruded by Cretaceous granite of the Billings Batholith. Stream sediment sampling followed by grid soil sampling located a tungsten soil anomaly (up to 267 ppm) but prospecting failed to find any mineralization.
An unmineralized 15 m thick garnet skarn was found on the north side of the claims. A fault which cuts this skarn off to the northwest is weakly mineralized with arsenopyrite. Regionally, the calc-silicate unit contains traces of chalcopyrite but none was found on the claims.
