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 (Location): A PRODUCTIVE PLACER AREA OF APPROXIMATELY 55 SQ. MI. LARGELY TO THE WEST OF THE GIVEN LOCATION. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Commodity): CONCENTRATES WERE RELATIVELY ENRICHED IN MOBIUM AND RARE EARTH ELEMENTS, BUT THESE WERE NOT RECOVERED
Comment (Production): THESE ARE VERY ROUGH ESTIMATES
Comment (Deposit): DEPOSITS LIE INBENCHES IN MAIN STREAMS AND IN RECONCENTRATES OF THESE BENCHES IN THE BEDS OF THEIR TRIBUTARIES. GOLD IN AMERICAN CREEK IS IN STREAM BED.
