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 = Brief reconnaissance geologic mapping and a few silt samples reported by Christie (1974). Moderate silver to 1.9 ppm, otherwise background levels for copper, molybdenum, zinc, and gold.

Comment (Reference): Primary Reference = Christie, 1974

Comment (Geology): Geologic Description = Color anomaly 3,000 by 2,000 ft (900 by 600 m) elongate along a northeast trend. Country rocks are marine clastic sedimentary rocks and andesite flows and breccias cut by diorite and feldspar porphyry dikes. Pyrite is disseminated in weakly altered diorite dikes and occurs along fractures and disseminated in the country rocks.

Comment (Exploration): Status = Inactive

Comment (Deposit): Model Name = Epithermal gold vein, polymetallic vein

Comment (Deposit): Model Number = 22c, 25

Comment (Geology): Age = Miocene or younger
