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 (Deposit): Model Name = Possibly Cyprus massive sulfide (Cox and Singer, 1986; model 24a)
Comment (Geology): Age = Tertiary based on the age of the Orca Group (Nelson and others, 1985).
Comment (Reference): Primary Reference = Jansons and others, 1984
Comment (Workings): Workings / Exploration = Jansons and others (1984) reported a 15 ft. open cut. Three samples contained 24-140 ppm Cu.
Comment (Geology): Geologic Description = This prospect reportedly is in a 3-foot-wide shear zone in slate of the Tertiary Orca Group (Jansons and others, 1984). Volcanic rocks crop out near the prospect (Nelson and others, 1985). Examination of the area by the U.S. Bureau of Mines in the early 1980s showed no obvious signs of mineralization. Three samples contained 24-140 ppm Cu (Jansons and others, 1984).
Comment (Deposit): Other Comments = Chugach Alaska Corporation, Anchorage, Alaska has control of these lands.
Comment (Exploration): Status = Inactive
