Comments on the geologic information

  • Geologic Description = The placer deposit occurs within First Creek above its confluence with Dutch Creek. There is no published geologic description of the First Creek prospect. Reed and Nelson (1980) show the area underlain by Mesozoic sedimentary rocks (KJs). C.C. Hawley and Associates, Inc. (1978) suggest that Dutch Creek may be controlled by a northeast trending, high angle normal fault (Dutch Creek Lineament, Hawley and Clark, 1973) that is parallel to the structure controlling the Cache Creek drainage a mile and one half to the southeast. Clark and Hawley (1968) report gold fineness from Dutch and First Creeks, ranges from 875.75 to 877.75, averaging 876, and note that the total production from First Creek is probably small.? Also see Dutch Creek (TL033).
  • Age = Pleistocene.
