Comments on the geologic information

  • Geologic Description = Host rocks at this site consist of propylitically-altered(?) andesitic volcanic rocks of Tertiary or younger age. They contain 2-10 percent epidote and chlorite and up to 1 percent disseminated pyrite (Christie, 1974). These volcanic rocks are cut by numerous quartz veins and stringers; individual veins are up to several feet in width. The veins exhibit cockade structure and contain traces of visible pyrite. Some veins contain banded calcedonic quartz. Twelve rock samples collected by the Aleut-Quintana-Duval JV contained up to 420 ppm Cu, 0.03 ppm gold, 99 ppm molybdenum, 2.1 ppm silver, and 91 ppm zinc (Christie, 1974).
  • Age = Tertiary or younger.
