The Ruby 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 (Geology): Age = Pleistocene.
Comment (Reference): Primary Reference = Mertie, 1919
Comment (Production): Production Notes = Mertie (1919) describes the placer deposit as 4 feet of gravel on bedrock of Tertiary continental deposits. He reports that mining at the site in 1917 recovered a little fine, flaky platinum with the gold.
Comment (Workings): Workings / Exploration = The drainage has been prospected and mined by various small scale surface methods. No other data is available.
Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a).
Comment (Deposit): Other Comments = Also see Willow Creek (TL042).
Comment (Geology): Geologic Description = Ruby Gulch, a small tributary near the head of Willow Creek, cuts the contact between Mesozoic marine sedimentary rocks (KJs) and continentally derived Pliocene conglomerate of the Sterling (?) Formation (Tps) mapped by Reed and Nelson (1980). Mertie (1919) describes the placer deposit as 4 feet of gravel on bedrock of Tertiary continental deposits. He reports that mining at the site in 1917 recovered a little fine, flaky platinum with the gold.
