Location: Located along west tributary to Nanushuk River, 10 km south of Nanushuk Lake. Known to within one mile.
Geology: Quartz-carbonate veins are exposed in a 15 m-wide zone along the south canyon wall where they cut interbedded siltstone and shale of the Hunt Fork Shale. The veins are up to 30 cm wide and can be traced for at least 8 m along strike. Barite is mainly concentrated along the vein margins which locally contain breccia and slickensides. The vein margins also contain minor chalcopyrite and galena.
Workings: Samples contain up to 420 ppm Cu, 343 ppm Zn, 54 ppm Pb, and more than 2,000 ppm Ba
Commodities (Major) - Cu; (Minor) - Ba, Pb
Development Status: No
Deposit Model: Cu quartz veins
