|Location and accuracy||This occurrence is about 1.5 miles east of Wild Lake, east of the mouth of Seward Creek. It is at an elevation of about 3,450 feet at the northeast end of a small ridge, near the center of section 23, T. 31 N., R. 18 W., of the Fairbanks Meridian. The location is accurate.|
Geologic descriptionThis occurrence consists of oxidized and locally mineralized quartz veins in Devonian schist and phyllite (Chipp, 1972). Of three, selected samples of the veins, one contained malachite, one contained tetrahedrite, and one contained an unknown gray mineral (Chipp, 1972; Kurtak and others, 1999). The tetrahedrite-bearing sample contains 6.5 ppm gold, 13 ppm silver, 2,400 ppm copper, and 2,000 ppm antimony (Chipp, 1972; sample 138). Analyses of the other samples showed no valuable metals. No other information is available.
