Economic information

Comments on the geologic information

  • Geologic Description = Limestone and diorite float boulders contain disseminated pyrite, magnetite, and chalcopyrite. Limestone has been slightly altered to skarn, calc-silicate veins cut diorite and granodiorite. Stream sediment samples yielded up to 220 ppm Cu, 500 ppm Zn, 0.4 ppm Au (Resource Associates of Alaska, 1976). The locality is in the vicinity of a contact between Tertiary medium-grained biotite-hornblende granodiorite unit (with some granite and quartz monzodiorite) and a Cretaceous granodiorite unit which ranges in composition from mafic tonalite to quartz diorite (Nelson and others, 1983; units Ti11 and Ki9).
  • Age = Intrusives associated with the skarn are Cretaceous to Tertiary.
