Location: The Hummel prospect is in Section 15 at an elevation of about 4300 feet on a steep, south-facing mountainside overlooking upper West Fork of Texas Creek. It is about 1.5 mile northeast of Texas Lake (Elliott and Koch, 1981, p. 11, loc. 29). The location is accurate to within about a quarter of a mile.
Geology: 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.
Workings: Minor surface exploration. An early assay of a nearly pure sample of the sphalerite showed 22.78 oz of Ag and 0.02 oz of Au per ton.
