Location: This site is at an elevation of about 3500 feet on a ridge about 4 miles west of Beaver Creek. It is in the NE1/4 of sec. 29, T. 20 N., R. 16 E., of the Kateel River Meridian. The location is accurate to within 1000 ft. The site corresponds to location 67 of Garland and others (1975, DGGS OFR 67).
Geology: This deposit is associated with skarns in medium-grade metamorphic rocks, irregular quartz veins or segregations containing galena and sphalerite. The deposit crops out in an area of at least 10 x 40 feet. The deposit may be related to a small granite pluton nearby. Samples from surface trenching contained 2800 ppm Ag and 5000 ppm Zn (Garland and others, 1975, DGGS OFR 67). Other analysis of massive galena indicates up to 1000 ppm Ag and 700 ppm Sb (Grybeck and Nelson, 1981). The deposit was staked in about 1976; work aparently was limited to surface trenching.
