Location: The Quartz Creek occurrence is at an elevation of about 5,100 feet on a high ridge approximately 9 1/2 miles north of Horace Mountain and 5 miles southwest of the confluence of Quartz Creek and the North Fork Chandalar River (at the common corner of secs. 4, 5, T. 34 N., R. 7 W. and secs. 32, 33, T. 35 N., R. 7 W. of the Fairbanks Meridian). The location is accurate within a 1-mile radius.
Geology: Mulligan (1974) described this occurrence as a quartz vein, about 2 inches thick, which cuts a chlorite schist. The vein contains minor goethite, malachite, and a trace of zinc (the zinc mineral is not specified). Float in the area contains traces of malachite and possibly chalcopyrite. The country rocks are Devonian black slate, phyllite, and phyllitic siltstone (Brosg
