Location: Located along west tributary of the Itkillik River, 18.8 km southwest of Thibodeaux Mountain. Known to within one mile.
Geology: Bedrock in the area consists of folded and faulted Hunt Fork Shale that is locally cut by quartz and sulfide-bearing quartz-carbonate veins and veinlets. Cobble-sized pieces of rounded massive white barite, containing streaks and blebs of galena were found as float. The source of the float is unknown. In another gully 800 m to the northeast, lense-like quartz-calcite-siderite veins are confined to a 50 cm-wide zone that trends northwest. The veins contain minor chalcopyrite and trace galena. No zinc minerals were observed.
Workings: Float of barite-galena cobbles contain up to 62% Ba, 0.67% Pb,and 25 g/tonne Ag. Veins from outcrop contain 735 ppm Cu and 3,900 ppm Zn.
Commodities (Major) - Ag, Ba, Pb, Zn; (Minor) - Cu
Development Status: No
Deposit Model: Pb-Zn quartz veins
