The McCann Creek is a pge 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 (Workings): Workings / Exploration = Some exploration drill holes have probably been drilled along this creek; no mining has been reported.
Comment (Deposit): Model Name = Placer PGE-Au (Cox and Singer, 1986; model 39b)
Comment (Commodity): Ore Material = platinum-group metal (PGM) alloys
Comment (Reserve-Resource): Reserves = Fechner (1988, p. 28) estimates that there are 500,000 cubic yards of material grading 0.0030 ounce of PGM per cubic yard in McCann Creek.
Comment (Reference): Primary Reference = Mertie, 1976
Comment (Geology): Geologic Description = Platinum-group metals have been identified in this creek but no workable paystreak has been found. PGM-rich material contains 95.5 percent Pt, 2.8 percent Ir, 1.2 percent Rh, and 0.5 percent Pd (Mertie, 1976). The creek flows across Paleozoic or Mesozoic sedimentary and igneous rocks that are intruded by the Jurassic Red Mountain ultramafic pluton (Hoare and Coonrad, 1978). Dunite of this pluton is within a few hundred feet of the upstream limit of the creek.
Comment (Exploration): Status = Active?
Comment (Geology): Age = Quaternary.
