The Shovel 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 (Deposit): Other Comments = Stream gradient approximately 250-300 feet per mile.
Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a).
Comment (Geology): Age = Quaternary.
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Miller and Ferrians, 1968
Comment (Workings): Workings / Exploration = The creek has been placer mined on a small scale. The site was examined and some rock samples collected by the U.S. Geological Survey during the 1960's. One hundred lode claims were staked in the vicinity in 1972 (Grybeck, 1977).
Comment (Geology): Geologic Description = Shovel Creek heads in the Upper Cretaceous Purcell Mountain quartz monzonite pluton, and crosses a contact between Jurassic-Lower Cretaceous andesitic volcanic rocks and the quartz monzonite. No large zones of altered rock were observed in the area, but abundant cobbles of black tourmaline and of albitized quartz monzonite containing tourmaline veinlets occur in the placer tailings and stream gravels. The quartz monzonite appears to be altered adjacent to the veinlets. Analyses of two tourmaline-rich cobbles show 700 and 1,000 ppm copper but no detectable gold. Indications are that the placer gold may have come from the quartz-tourmaline veins (Miller and Ferrians, 1968).
