Capsule

Work History

Staked in Aug/54 by F. Ryhorchuk & T.C. Richards as Acme cl (69304), and Trout cl (69344) 3.2 km west, which were optioned by Bell Asbestos late in the year and explored with extensive trenching and two holes (306.6 m) in 1955. The adjoining Rex cl (69543) were staked in Sep/54 by A. Green and transferred to Prospectors Airways CL on behalf of a syndicate including Noranda ML and Kerr Addison Gold ML and mapped by Asbestos Corp in 1955 under option.

Capsule Geology

A 0.5 cm chrysotile asbestos veinlet was found in a peridotite boulder in a tributary of Caribou Creek but only tiny veinlets were found in place on the Acme and Trout groups. No mineralization was found on the Rex group. The ultramafic body is composed of pyroxenite, peridotite, dunite and gabbro phases. It occurs in a major thrust fault and is of Carboniferous and Permian age.
