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 (Deposit): Other Comments = Stream gradient approximately 100 to 150 feet per mile.

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

Comment (Geology): Age = Quaternary.

Comment (Workings): Workings / Exploration = Four test holes were sunk to bedrock (Reed, 1932).

Comment (Reference): Primary Reference = Reed, 1932

Comment (Geology): Geologic Description = The bedrock of this placer deposit is early to mid-Paleozoic schist (Cobb and others, 1981). Depth to bedrock is 5 to 6 feet in the stream bed and 8 to 9 feet in areas adjacent to the stream bed. Gravel is pebble- to cobble-sized material, and a few boulders. Four holes were sunk to bedrock at the bend of the creek (Reed, 1932). The gold reportedly is fine and flaky.
