Comments on the geologic information

  • Geologic Description = Samples of quartz diorite with scheelite contained from 0.045 to 0.35% tungsten (Conwell, 1972). Petrographic examination of the quartz diorite identified the following minerals associated with the tungsten ore: quartz, plagioclase, potassium feldspar, biotite, and amphibole. No significant gold or silver was found upon atomic absorption analysis (0.002 to 0.008 ounces of gold per ton; 0.015 to 0.02 ounces of silver per ton) (Conwell, 1972).
