Comments on the geologic information

  • Geologic Description = Bedrock in the general area of the Cub Creek mine includes syenite of the Late Cretaceous Granite Mountain pluton, and, in the lower portion of the creek, Jurassic-Cretaceous andesite and greenstone. Creek boulders are largely syenite, monzonite, or diorite. The deposit is a gold placer; gold is distributed through 2 feet of gravel overlying bedrock. The gold is fine and flaky and assays $19.20 per ounce (gold at $20.67/ounce) (Harrington, 1919). Concentrates contain a little pyrite and abundant magnetite (Moffit, 1905). Gault and others (1953) found uranothorianite in the placer concentrates on Cub Creek and its headwaters.
  • Age = Quaternary.
