The Granite 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 (Reference): Primary Reference = Moffit, 1938
Comment (Workings): Workings / Exploration = Granite Creek was sufficiently auriferous to be prospected for several seasons prior to World War II (Moffit, 1938, p.51). Production, if any, was small.
Comment (Production): Production Notes = Probably minor if any.
Comment (Geology): Geologic Description = Granite Creek mainly flows on the dioritic phase of the Pennsylvanian to Permian, Ahtell pluton and sedimentary and volcanic rocks of the Pennsylvanian to Permian, Slana Spur Formation (Richter, Lanphere, and Matson, 1975). Granite Creek was sufficiently auriferous to be prospected for several seasons before World War II (Moffit, 1938, p.51). Production, if any, was small. The placer is probably of river-bar type.
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
Comment (Geology): Age = Holocene placer.
Comment (Exploration): Status = Inactive
