Geologic setting

Geologic description

Occurrence detected from pan concentrates only, no rock samples taken.
Stream sediment samples yield up to 500 ppm Au, 30 ppm Ag, and 500 ppm Sn (Eakins and others, 1978). The nearby bedrock is composed of a rhyolite or dacite dome complex and quartz monzonite intrusions (?) that has been locally sericitized, silicified, and contains gossan (Eakins and others, 1978).
