This site is located on land patented by, or interim-conveyed to, the Aleut Corporation.

Location: This occurrence is approximately located. The map site is at an elevation of about 700 feet, due south of 1,630 foot peak of Apollo Mountain on southeastern Unga Island (MacKevett and Holloway, 1977, locality 13; Wilson and others, 1988, locality 13). The location is accurate to within 2 miles.

Geology: This occurrence consists of quartz veins less than 12 inches thick that crop out discontinuously along stike for 2,500 feet. It also includes a knoblike, 100- by 1,000-foot area of brecciated and silicified andesite containing numerous quartz-filled vugs and limonitic shears. The vein system cuts rocks mapped as Popof volcanic rocks of late Eocene to early Oligocene age (Wilson and others, 1995). Grab samples of the quartz contained as much as 0.23 ppm gold and 10 ppm silver (Wilson and others, 1988). Base metal values are low.

Workings: Some evaluation work may have been done by UNC Teton Exploration Drilling Company for the Aleut Corporation in 1979, 1981, and 1982 (Wilson and others, 1988). Grab samples contained as much as 0.23 ppm gold and 10 ppm silver. Base metal values were low.

Age: Eocene or younger.
