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 (Reference): Primary Reference = Wilson and others, 1988
Comment (Geology): Age = Eocene or younger.
Comment (Geology): Geologic Description = This prospect is a vuggy, oxidized quartz vein that strikes N 38 E and has a strike length of approximately 500 feet (Wilson and others, 1988). It occurs in volcanic rocks of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). The vein is exposed in a short adit and may be the southwestern continuation of the Sitka fracture system (Wilson and others, 1988). Sulfides present in the vein include chalcopyrite, galena, pyrite, and sphalerite.
Comment (Deposit): Model Name = Epithermal gold vein, Polymetallic vein (Cox and Singer, 1986; model 22c)
Comment (Workings): Workings / Exploration = This prospect has been explored by a short adit.
Comment (Exploration): Status = Inactive
