Geologic setting

Geologic description

This unnamed prospect was explored by a 25-foot adit; it may be related to claims staked in 1905 (Kimble and others, 1984). A 23-foot-long channel sample taken along the length of the adit contained 0.05 part per million (ppm) silver and 70 ppm lead (i.e., barely above background). The host rock is schist, part of the Cretaceous greenschist unit of Brew and Grybeck (1984).
