|Location and accuracy||This occurrence is at an elevation of about 1,250 feet, 1.5 miles northwest of Dakavak Bay and 2 miles west-southwest of the southern tip of Dakavak Lake. It is in the SE1/4 sec. 19, T. 24 S., R. 33 W., of the Seward Meridian. The location is accurate within one-half mile.|
Geologic descriptionThis occurrence consists of pyrite-bearing quartz veins in the Late Cretaceous Kaguyak and the Oligocene Hemlock Formations that are intruded by a Tertiary pluton (Riehle and others, 1993). Church, Riehle, and Goldfarb (1993) collected samples that contain up to 370 parts per million (ppm) zinc, 200 ppm copper, 50 ppm cobalt, 30 ppm arsenic, and 4 ppm antimony.
