Comments on the geologic information

  • Geologic Description = This occurrence represents the northern end of the Kizhuyak lode. Here the granodiorite on the beach is cut by numerous quartz veins striking N. 15 W. and containing local lenses of pyrrhotite. A sample collected by Rose and Richter assayed 0.10 ounce per ton gold, 1.10 ounce per ton silver, 0.15 percent copper, and trace arsenic. A few hundred feet to the south an area of graywacke inclusions is cut by numerous quartz veins containing minor pyrrhotite and traces of chalcopyrite.
  • Age = Tertiary
