|Location and accuracy||This site, color anomaly 43 of Christie (1974), is located on the southeast coast of Akun Island. The occurrence is on the north and south shores of the southwest arm of Trident Bay. Site location is accurate to within 500 feet.|
This occurrence represents a color anomaly which is approximately 1,500 by 200 feet (Christie, 1974). Rocks at this site include andesite, vescicular andesite, feldspar porphyry, basalt, tuff, and conglomerate. The volcanic rocks are of probable Tertiary age (Christie, 1974; Simpson, 1985). The primary feldspars have been partially altered to clay and epidote. Strong gossan occurs along the north shore of the southwest arm at Trident Bay. Extensions of this gossan may be covered by the conglomerate. A weak gossan is present along the south shore of this arm of the bay. The altered rocks contain 1 to 4 percent pyrite, with only a minor amount of which occurs as fracture fillings.The Aleut-Quintana-Duval JV collected 5 silt and 2 soil samples at this site in 1974 (Christie, 1974). No anomalous metal values were detected.
