Comments on the geologic information

  • Geologic Description = The Goodwin gold prospect consists of a 50-foot-wide zone of brecciated iron-stained schist that strikes N. 70 E. and has a vertical dip (Hill, 1933, p. 153). In 1931, Hill attempted to determine the average value of this zone by taking grab samples from various dumps; these samples assayed only 23 cents in gold per ton (Hill, 1933, p. 153-154). Bedrock in the area is Fairbanks Schist that consists of quartz-muscovite schist, quartzite, and chlorite-quartz schist (Newberry and others, 1996).
