Comments on the geologic information

  • Geologic Description = 0.2 ppm Au was detected in gray, sulfide-bearing quartzite which is adjacent to a small granitic intrusive (Foster and others, 1984). Country rocks are Precambrian and/or Paleozoic quartzite and quartzitic schists intruded and contact metamorphosed by an upper Cretaceous to lower Tertiary granitic pluton. The area is cut by a left-lateral fault and was intruded by felsic hypabyssal rocks, probably in the early Tertiary.
