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 (Reserve-Resource): GSW BULL 50, P.81
Comment (Production): $96,000
Comment (Geology): ON THE KEYSTONE-FLORENCE MINERALIZED TREND.
Comment (Development): CLEAN UP OPERATIONS WERE CONDUCTED IN 1916 AND 1939, AND THE MINE PLANT DISMANTLED AND SHAFT SEALED IN THE 1950'S
Comment (General): Wilson and Heran (USGS) visited this site in August, 2010. All that remains are a few very caved workings and small dumps at the entrance of a driveway to a couple of summer/vacation cabins. Consider this an abandoned mine.
