The Long Creek is a zinc, lead, copper, gold, and silver 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.

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 = Hawley and Clark, 1974
Comment (Workings): Workings / Exploration = Surface trenches and soil grids.
Comment (Geology): Geologic Description = This prospect is near the faulted contact between Devonian mafic intrusive rocks and Upper Devonian to Lower Triassic tuffaceous chert, volcanic conglomerate, graywacke and shale, and limestone (Wilson and others, 1998). Both units are intruded by Upper Cretaceous (?) porphyry dikes. The deposit consists of massive quartz-arsenopyrite veins that also contain minor amounts of galena, sphalerite, pyrite and chalcopyrite. In addition to the veins, rocks also contain up to 2% disseminated sulfides in a 600- feet by 300-foot area.
Comment (Exploration): Status = Active
Comment (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c)
Comment (Geology): Age = Probably Late Cretaceous or younger, assuming that the deposit is related to the diorite dikes.
