Location and accuracy This site is located approximately 6 miles west-northwest of Kettle Cape and 2 miles northeast of VABM Ande, at an elevation of about 1000 feet. It corresponds Christie's (1974) color anomaly 31. Site location is accurate to within 1 mile.

Geologic setting

Geologic description

Host rocks at this site consist of propylitically-altered(?) andesitic volcanic rocks of Tertiary or younger age. They contain 2-10 percent epidote and chlorite and up to 1 percent disseminated pyrite (Christie, 1974). These volcanic rocks are cut by numerous quartz veins and stringers; individual veins are up to several feet in width. The veins exhibit cockade structure and contain traces of visible pyrite. Some veins contain banded chalcedonic quartz. Twelve rock samples collected by the Aleut-Quintana-Duval JV contained up to 420 ppm Cu, 0.03 ppm gold, 99 ppm molybdenum, 2.1 ppm silver, and 91 ppm zinc (Christie, 1974).
