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 = Samples contain up to 420 ppm Cu, 343 ppm Zn, 54 ppm Pb, and more than 2,000 ppm Ba
Comment (Deposit): Model Name = Cu quartz veins
Comment (Geology): Geologic Description = Quartz-carbonate veins are exposed in a 15 m-wide zone along the south canyon wall where they cut interbedded siltstone and shale of the Hunt Fork Shale. The veins are up to 30 cm wide and can be traced for at least 8 m along strike. Barite is mainly concentrated along the vein margins which locally contain breccia and slickensides. The vein margins also contain minor chalcopyrite and galena.
Comment (Reference): Primary Reference = Kurtak and others, 1995, USBM OFR 8-95
Comment (Exploration): Status = Inactive
