Comments on the geologic information

  • Geologic Description = The area of this site is marked by a 1- by 2-mile color anomaly (Christie, 1974, number 75) in the late Eocene to early Oligocene Stepovak Formation (Wilson and others, 1995). The bedded rocks are intruded by several plutons. Christie described the occurrence as sparse calcite veins and vein breccias containing a trace of pyrite. He collected six silt samples that contained as much as 0.01 ppm gold, 1.8 ppm silver, 70 ppm copper, 102 ppm zinc, and 4 ppm molybdenum.
  • Age = Eocene or younger.
