Comments on the geologic information

  • Geologic Description = This sample is from a 75- to 100-foot wide N 60 E-trending breccia zone in quartzite. The zone contains quartz veinlets one-eighth inch to 1 inch wide. Possible arsenopyrite found in quartz boxwork; samples of the brecciated quartzite contain 0.7 ppm Au and 1.0 ppm Ag (Foster and others, 1984).
