The Russian Bay is a gold and silver 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.

Comment (Geology): Geologic Description = This site was called the Russian Bay prospect by Randolph and Ellis (1989). It is a geothermal area of hot-springs and one active fumarole and is marked by an 8,000 x 10,000 foot color anomaly. Many centers of extreme acid leaching are present and consist of blue-grey pyritic clay and minor silica. An intensely silicified fault breccia occurs at one locality on the east edge of the color anomaly. Fifty-three rock samples collected by Battle Mountain Exploration contained up to 745 ppm arsenic, 104 ppb gold, > 5 ppm mercury, 23 ppm molybdenum, and 3.8 ppm silver (Randolph and Ellis, 1989).
