Location: This occurrence is on the northeast side of the Zane Hills, south of upper Caribou Creek. The map site is at an elevation of about 2,150 feet, about 0.5 mile south-southwest of the center of section 31, T. 9 N., R. 14 E. of the Kateel River Meridian. The location is accurate within one-half mile.
Geology: This occurrence consists of pyritiferous, silicified, fine-grained intrusive rock near the contact between two phases of the Cretaceous, Zane Hills pluton (Miller and Ferrians, 1968). The principal phase is granodiorite and quartz monzonite; the other is a border phase of porphyritic monzonite and quartz monzonite. A sample of the principal phase near the contact contains 200 ppm silver, 1,000 ppm bismuth, 700 ppm tungsten, and 500 ppm lead (Miller and Ferrians, 1968). No other information is available.
Workings: Only surface sampling.
Age: The Zane Hills pluton is 81 Ma as dated by K/Ar methods (Miller and others, 1966).
Alteration: Pyritization and silicification of pluton.
Commodities (Major) - Ag, Bi, W; (Minor) - Pb
Development Status: None
Deposit Model: Porphyry Cu-Au (?) (Cox and Singer, 1986; model 20c)
