Geologic setting

Geologic description

This site is a gold placer mine about 0.5 mile below the headwater forks of Bear Creek. Bedrock in area is early to mid-Paleozoic marble and schist. Prospect was mined intermittently for several years prior to 1930. Mining was done in the portion of the stream underlain by schist (Reed, 1932).

Production and reserves

Workings or exploration Central and Bear valleys were optioned as prospective placer ground in the early 1930s. Preliminary examinations were begun to determine the feasibility of installing hydraulic equipment or a dredge. A line for a ditch about 3 miles long was laid out and surveyed. Prospecting continued through the winter of 1934-35 (Smith, 1936).
Indication of production Yes; small
Production notes Production through 1930 reported as 95 ounces (Cobb and others, 1981).
