Location and accuracy	This prospect is at an elevation of about 3500 feet in a pass northwest of a tributary to Mauneluk River. It is in the N1/2 of sec. 22, T. 21 N., R. 13 E., of the Kateel River Meridian. The location is accurate to within 1000 ft. The site corresponds to locality 55 of Grybeck and Nelson (1981).

Geologic setting

Geologic description The deposit consists of sulfide-bearing carbonates, probably the Skajit Limestone (Nelson and Grybeck, 1980). More than forty, 1 to 5 cm bands of galena and sphalerite with copper and silver values were intersected in 122 m of diamond drill hole. There was considerable staking in the area and limited diamond drilling in 1976.
