The Neacola River is a copper and molybdenum mine located in Alaska.
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 (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Disseminated quartz veins containing pyrite, azurite, and traces of bornite in medium- to coarse-grained biotite-hornblende granodiorite (Nelson and others, 1983; unit Ti4). The quartz veins locally contain 3,600 ppm Mo and 8,800 ppm Cu.
Comment (Deposit): Other Comments = Area is very rugged and partly covered by glaciers. Site is in Lake Clark National Park and Preserve.
Comment (Deposit): Model Name = Porphyry Cu-Mo (Cox and Singer, 1986; model 21a)
Comment (Reference): Primary Reference = Nelson and others, 1985
Comment (Reserve-Resource): Reserves = No reserves
Comment (Workings): Workings / Exploration = Veins locally contain 3,600 ppm Mo and 8,800 ppm Cu (Nelson and others, 1985).
Comment (Production): Production Notes = No production
Comment (Geology): Age = Veins cut Tertiary granodiorite.
