This site is one of numerous occurrences of argentiferous galena, sphalerite, pyrite and arsenopyrite in an 18-mile-long, 2- to 5-mile-wide zone of altered andesite surrounding the Quartz Creek quartz monzonite pluton. The altered zone trends N 15 W, across the drainage basins of Quartz Creek and the Kiwalik River, parallel to prominent lineaments in the area.
Location: This occurrence is at an elevation of about 450 feet, on an unnamed tributary of Quartz Creek between Deer and Buck Creeks. The map site is in section 18, T. 2 N., R. 13 W., of the Kateel River Meridian. Cobb, 1972 (MF-389), location 4, and Miller and Elliott (1969), figure 2, location 7.
Geology: This occurrence consists of a calcite veinlet containing minor galena. The veinlet cuts altered Jurassic-Cretaceous andesite near its contact with quartz monzonite of the Cretaceous Quartz Creek pluton. A grab sample from this location contained: 300 ppm Pb and a trace Ag (Miller and Elliott, 1969).
Workings: The area has been mapped and examined by the U.S. Geological Survey and various exploration companies.
Age: Late Cretaceous.
Alteration: Hydrothermal.
Commodities (Major) - Ag, Pb
Development Status: None
Deposit Model: Galena in calcite vein.
