|Location and accuracy||The site is a placer mine 0.5 miles below the headwater forks of Bear Creek. Cobb (1972, MF-386), location 9 and Schmidt and Allegro (1988), location 284. This placer ground is in sections 6 and 7, T. 20 N., R. 7 W., of the Kateel River Meridian.|
Geologic descriptionThis 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).

|Mineral deposit model||Placer Au (Cox and Singer, 1986; model 39a).|
|Mineral deposit model number||39a|
|Age of mineralization||Quaternary.|
|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).|
