Comments on the geologic information

  • Geologic Description = The rocks at this site consist of Cretaceous Hoodoo Formation cut by andesite dikes. The U.S. Geological Survey sampled a pyritic quartz vein which cuts hornfelsed siltstone of the Hoodoo Formation at this site (Angeloni and others, 1985). The width of the vein is unknown. The sample of vein material ran 200 ppm antimony, >10,000 ppm arsenic, 1,500 ppm copper, 1,500 ppm lead, 150 ppm silver; and >10,000 ppm zinc.
  • Age = Tertiary

Comments on the workings information

  • Workings / Exploration = Rock sample (83AWs 57) of vein material collected by the U.S. Geological Survey contained 200 ppm antimony, >10,000 ppm arsenic, 1,500 ppm copper, 1,500 ppm lead, 150 ppm silver, and >10,000 ppm zinc.
