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.

Comment (Deposit): PLACER GOLD WAS DISCOVERED IN 1931 BY RUFUS STEVENS. IN 1932 THE OREGON-NEVADA MINING CO. ACQUIRED 300 ACRES AND ATTEMPTED AN UNSUCCESSFUL VENTURE TO WORK GRAVELS ON LARGE SCALE. SUBSEQUENT WORK IN 1930'S WAS BY INDIVIDUALS LEASING THE GROUND TO WORK. BEST VALUES ARE AT SHALLOW DEPTH ABOVE A FALSE CLAY BEDROCK AT DEPTHS OF 8 INCHES TO 2 FEET.
