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 (Workings): Workings / Exploration = Jansons and others (1984) reported grab samples contained 0.15 percent Pb, 10 ppm Ag, and 0.2 percent As.

Comment (Reference): Primary Reference = Jansons and others, 1984

Comment (Geology): Geologic Description = Limonite-stained quartz-cemented fractures in Tertiary biotite +/- hornblende granite. USGS grab samples contained 0.15 percent Pb, 10 ppm Ag, and 0.2 percent As (Jansons and others, 1984).
