Location: This occurrence is located about 4.5 miles north of Wiseman near the top of the ridge at the head of Steep Gulch. The occurrence is at an elevation of 2,900 feet in about the center of the NE1/4 section 31, T. 31 N., R. 11 W., of the Fairbanks Meridian. The location is accurate.
Geology: This occurrence consists of an auriferous, pyrite-bearing quartz vein. A select sample of the quartz vein contains 810 ppb gold (Eden, 2000). Eden indicates that this vein is an extension of a system of gold-quartz veins in the Nolan area. The rocks in the area consist of quartz-mica schist interlayered with chlorite schist and phyllite (Eden, 2000). No other information is available.
Workings: Surface sampling and geologic mapping.
Commodities (Major) - Au
Development Status: None
