Comments on the geologic information

  • Geologic Description = The country rocks at this occurrence consist either of sedimentary units of the Miocene Bear Lake Formation or of volcanic and sedimentary units of the Oligocene to Eocene Stepovak Bay Formation (Wilson and others, 1995). Christie (1974) noted a small color anomaly at this location. He collected one silt sample that contained 48 ppm copper, 4 ppm molybdenum, 63 ppm zinc, and 1.6 ppm silver. MacKevett and Holloway (1977) describe the occurrence as an altered zone in Tertiary rocks.
  • Age = Eocene or younger.
