The Big Joe Creek is a gold 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 (Geology): Age = Middle Cretaceous based on arguments by Dillon (1982) that the age of emplacement of the gold-bearing quartz veins of the Koyukuk and Chandalar districts was between the Neocomian metamorphism of the Devonian host rocks and their erosional unroofing and cooling in Albian time.
Comment (Geology): Age = Host rock is Devonian.
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Low-sulfide Au-quartz veins(?) (Cox and Singer, 1986; model 36a)
Comment (Geology): Geologic Description = The prospect is described only as gold in a quartz vein (Brosgi and Reiser, 1972) in an area mapped as Devonian(?) black, fine-grained quartz-muscovite-chlorite schist with intercalated Devonian(?) green, schistose hornblende diorite and pyroxene diorite sills and andesitic flows(?) (Brosgi and Reiser, 1964). A rock sample from this occurrence contained 0.04 to 0.079 ppm Au. No other descriptive information is available for this occurrence.
Comment (Reference): Primary Reference = Brosgi and Reiser, 1972
Comment (Workings): Workings / Exploration = No information available.
