The Halibut Bay 15G is a copper and nickel 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 (Deposit): Other Comments = Site is located within Kodiak National Wildlife Refuge.
Comment (Deposit): Model Name = Synorogenic-synvolcanic Ni-Cu (Cox and Singer, 1986; model 7a?)
Comment (Workings): Workings / Exploration = A grab sample from this locality contained 1,700 ppm copper, 420 ppm nickel, 25 ppm cobalt, and traces of gold, silver, platinum, and palladium.
Comment (Geology): Geologic Description = At this mineral occurrence, one of several within the Halibut Bay ultramafic complex, chalcopyrite and pyrrhotite are present as disseminations in a 3-foot layer of gabbro. The gabbro layer lies between pyroxenite and peridotite. A sample of this material contained 1,700 ppm copper, 420 ppm nickel, 25 ppm cobalt, and traces of gold, silver, platinum, and palladium (Foley and Barker, 1985, table 14). ? the Halibut Bay ultramafic complex, consisting mostly of dunite, gabbro, pyroxenite, and peridotite, occurs within sedimentary units of the Uyak formation of Cretaceous age.
Comment (Reference): Primary Reference = Foley and Barker, 1985
Comment (Exploration): Status = Inactive
