Comments on the geologic information

  • Geologic Description = The Disney prospect consists of a siliceous knob 150 feet in diameter near a strong northeast-trending fault. Quartz and red jasper float are also present. The host rocks are andesite tuffs of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others,1995). The tuffs are argillized, chloritized, and locally silicified. Trenching exposed thin quartz and jasper veins as much as 2 feet thick. The highest precious metal values obtained in grab samples are 0.20 ppm gold and 18 ppm silver. Channel samples contained as much as 0.015 ppm gold (one sample only), 0.2 ppm silver, 171 ppm lead, 106 ppm zinc, 330 ppm arsenic, and 2.8 ppm mercury (Peterson and others, 1982).
  • Age = Eocene or younger.
