Comments on the geologic information

  • Geologic Description = The country rocks in the area of the Hummel prospect include pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; the Triassic Texas Creek Granodiorite, which underlies and locally intrudes the Hazelton; and the Eocene Hyder Quartz Monzonite, which intrudes both the Hazelton and Texas Creek rocks (Smith, 1977; Koch, 1996).? the deposit (Buddington, 1929, p. 98) consists of stringers of sulfides and quartz in a shear zone that cuts argillite and slate. The zone is at least 2 feet thick and contains up to 6 inches of solid sulfides along the hanging wall. The sulfides include sphalerite, galena, pyrite, chalcopyrite, and minor tetrahedrite. A nearly pure sample of the sphalerite contained 22.8 oz of Ag and 0.02 oz of Au per ton.
