Bear Creek

The Bear Creek is a gold mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = This site is a gold placer mine about0.5 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).

Comment (Production): Production Notes = Production through 1930 reported as 95 ounces (Cobb and others, 1981).

Comment (Reference): Primary Reference = Reed, 1932

Comment (Workings): Workings / Exploration = Central and Bear valleys were optioned as prospective placer ground in the early 1930's. 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).

Comment (Deposit): Other Comments = Stream gradient approximately 150 feet per mile in mining area.

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a).

Comment (Geology): Age = Quaternary.
