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 (Reference): Primary Reference = Richter, 1966
Comment (Workings): Workings / Exploration = Prospect pits.
Comment (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c)
Comment (Deposit): Other Comments = Additional information can be obtained from Ahtna Minerals in Anchorage, Alaska.
Comment (Commodity): Gangue = Carbonate minerals
Comment (Geology): Age = Emplaced subseqent to or is related to the border phase of the Pennsylvanian to Permian, Ahtell pluton.
Comment (Geology): Geologic Description = The prospect is in the Border Zone phase of the Pennsylvanian to Permian, Ahtell quartz monzonite pluton (Richter, 1966; Richter, Lanphere, and Matson, 1975). It is about 1/4 mile east of the contact of the pluton with rocks of the Pennsylvanian to Permian, Tetelna Formation. The deposit is a a quartz or quartz-carbonate vein that contains galena. The vein strikes north-northeast and dips 32 degrees East (Richter, fig. 5, 1966; WGM Inc., 1979).
