|Location and accuracy||The Steph occurrence is at an elevation of about 3,800 feet, approximately 5 1/2 miles west-northwest of Reds Lake in the hills north of and overlooking the North Fork Chandalar River (NW1/4 sec. 13, T. 35 N., R. 6 W., of the Fairbanks Meridian). The reference point corresponds to loc. 69 in DeYoung (1978) and is accurate within a 1/2-mile radius.|
Geologic descriptionThis occurrence is described as malachite, azurite, and tennantite in a quartz vein (Grybeck, 1977). The country rocks are Devonian Skajit Limestone near a large body of greenstone interpreted as schistose hornblende diorite, pyroxene diorite sills, and andesitic flows(?) (Brosgé and Reiser, 1964). No other information is available.
