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 (Geology): Geologic Description = Color anomaly 1.0 by 0.5 mi (1,600 by 800 m) elongate in northwest direction. Anomaly is in volcanic and epiclastic rocks intruded by granodiorite. Disseminated pyrite is source of color anomaly.

Comment (Reference): Primary Reference = Christie, 1974

Comment (Deposit): Model Number = 17, 25

Comment (Workings): Workings / Exploration = Brief reconnaissance geologic mapping and collection of a few silt samples reported by Christie (1974). Samples showed moderate silver (up to 1.5 ppm) and gold to 0.03 ppm. Copper, molybdenum, and zinc were all at low levels.

Comment (Deposit): Model Name = Copper porphyry, epithermal gold vein

Comment (Geology): Age = Miocene or younger
