Location: In upper Reed Creek valley, about 1 mile north-northeast from the end of the unimproved road that is parallel to Reed Creek. Accurate within 2,000 ft. Location 32 of Cobb (1972).
Geology: Shear zone in tonalite of Late Cretaceous to Tertiary age. Maloney (1966) reported the shear zone to be 200 ft wide and could be traced for 1,500 ft. The shear zone contains bornite, chalcopyrite, covellite, molybdenite, and pyrite; and strikes east, dipping 75 to 80 N. Mineralization is exposed over an area of 50 ft by 500 ft and over a vertical distance of 300 ft. Assays indicated 0.6 oz/ton Au, 1.81 oz/ton Ag, 4.58 percent Cu, and 2.06 percent Mo (Maloney, 1966).
Workings: Old adit, said to have been 40 ft long, was covered by rock slide prior to 1963. Assays indicated 0.6 oz/ton Au, 1.81 oz/ton Ag, 4.58 percent Cu, and 2.06 percent Mo (Maloney, 1966).
Age: Late Cretaceous or younger; shear zone cuts Late Cretaceous to Tertiary tonalite.
Alteration: Sericitization and carbonitization dominate (Ray, 1954).
Commodities (Major) - Ag, Au; (Minor) - Cu, Mo
