Comments on the geologic information

  • Geologic Description = This site represents the southern extension of the Kizhuyak lode as described by Capps (1937). Beach cliffs at this prospect show extensive mineralization in granodiorite near a contact with Cretaceous metasedimentary rocks. The deposit consists of a zone of many quartz veins up to 4 inches in thickness which are heavily mineralized in places with arsenopyrite and pyrite. The full width of the mineralized zone could not be determined. Several hundred feet on strike to the south similar mineralization is exposed in an open cut. The prospect was developed in 1934 by a 10-foot adit driven southward from the beach.
  • Age = Tertiary
