Location: This occurrence is located between Killak River and Lake Selby, about 3.5 miles north-northwest of the high point of land between Lake Selby and Narvak Lake and 3.5 miles southeast of Coal Pass. It is at an elevation of about 1,950 feet, 0.2 mile southwest of the center of section 10, T. 17 N., R. 14 E. of the Kateel River Meridian. Location is accurate within one-half mile.
Geology: This occurrence consists of a copper-bearing quartz vein in Cretaceous conglomerate (Patton and Miller, 1966). The vein contains chalcopyrite, and is stained with malachite, azurite, and limonite. The conglomerate borders pre-Cretaceous volcanic and metamorphic rocks, and the conglomerate is cut by a small, plug-like body of andesite porphyry. A rock sample contains more than 10% copper, 0.05% zinc, traces of cobalt, chromium, and nickel, 0.01 ounce of silver per ton, and no detectable gold. No other information is available.
Workings: Only surface sampling.
Age: Cretaceous or younger.
Alteration: Oxidation of chalcopyrite to secondary copper and iron minerals.
Commodities (Major) - Cu; (Minor) - Zn
Development Status: None
