|Location and accuracy||This occurrence is on a marble knob overlooking the Kwiniuk River. It is 0.5 miles east of the confluence of the Kwiniuk River and a major unnamed south tributary (the Corral Creek of West, 1953, Plate 1), and about 7 miles north-northeast of the village of Elim. The occurrence appears to be on Peak 673 but it may only be located within 0.5 mile. It is locality 63 of Gamble (1988).|
Geologic descriptionMiller and Grybeck (1973) report a small gossan in limestone; a grab sample of this gossan contained 500 ppm Cu, 300 ppm Pb, greater than 10,000 ppm Zn, and greater than 5,000 ppm Ba. Bedrock here is Paleozoic marble that is about 1.5 miles east of the Darby pluton (Till and others, 1986).

|Mineral deposit model||Base-metal sulfide veins or replacements in marble.|
|Age of mineralization||Not known; probably mid-Cretaceous or younger. K/Ar ages for the nearby Darby pluton are 88.3 +/- 1.5 and 92.8 +/- 2.6 Ma (Berry and others, 1976).|
|Alteration of deposit||Oxidation; the occurrence is described as a gossan.|
|Workings or exploration||There are no known workings or exploration activities at this locality.|
