|Location and accuracy||This site represents an old claim block on southeastern Unga Island. It is southwest of the Apollo mine (PM079) and approximately 1 mile west of the head of Delarof Bay (Wilson and others, 1988, locality 40). The map site is at an elevation of 700 feet, about 0.15 mile southeast of the center of sec. 6, T. 58 S., R. 74 W., of the Seward Meridian. The location is accurate to within 1 mile.|
Geologic descriptionThis prospect is described as two zones of reticulated quartz veins exposed in a 37-foot drift (Wilson and others, 1988). The zones decrease in width from 14 feet at the adit to 1 foot at the end of the drift, where they are faulted off. The veins contain no visible sulfides. They are hosted in the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). Five samples assayed by the U.S. Bureau of Mines contained as much as 0.3 ppm gold and 69 ppm silver (Wilson and others, 1988).
