The Rube 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 (Commodity): Gangue = black garnet (melanite)
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Quaternary.
Comment (Reference): Primary Reference = Harrington, 1919; Gault and others, 1953
Comment (Workings): Workings / Exploration = Small-scale placer mining was done on lower Rube Creek in the early 1900's. In 1945 the U.S. Geological Survey sampled the placer to evaluate its radioactive mineral potential. The site of old placer workings could not be found at that time. Little mining was done after the stampede in the early 1900's.
Comment (Geology): Geologic Description = Small-scale placer mining was done on lower Rube Creek in the early 1900's. Gold is concentrated on clay-rich, false bedrock and in the overlying 2 to 3 feet of gravel. Overburden is a variable thickness of barren gravel and sand and two feet or more of muck. A report of platinum is not verified. The heavy mineral concentrates include an unusual amount of black garnet (Harrington, 1919).
Comment (Commodity): Gangue = Chrome spinel
Comment (Deposit): Other Comments = Stream gradient approximately 100 feet per mile in lower mile of creek.
Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a).
