Comments on the geologic information

  • Geologic Description = The Engineer prospect is located along a ridge composed of Fairbanks Schist, which consists of quartz-muscovite schist, quartzite, and chlorite-quartz schist (Newberry and others, 1996). A grab sample from two, parallel, iron-stained, arsenopyrite-bearing quartz veins oriented N. 70 E., assayed $2.86 per ton or 0.14 ounce of gold per ton (Hill, 1933, p. 153).
