Location and accuracy The Copper Hill prospect is about 0.6 mile east-southeast of the Puyallup Mine which is named on the USGS 1;63,360-scale topographic map. The prospect is about 0.3 mile west-southwest of the center of section 32, T. 73 S., R. 84 E.

Geologic setting

Geologic description

The deposit at the Copper Hill prospect is a network of chalcopyrite veinlets in sheared greenstone (Brooks, 1902; Chapin, 1918). The property was explored by surface stripping in 1916 but apparently there has been no work on the property since. The greenstone is probably basalt or andesite of the Descon Formation of Silurian and Ordovician age (Herreid and Rose, 1966).
