Comments on the geologic information

  • 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).
  • Age = Tertiary or younger.
