This site is on land conveyed, patented, or selected by the Aleut Native Corporation.
Location: 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.
Geology: 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 calcedonic 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).
Workings: The Aleut-Quintana-Duval JV sampled this site in 1974 (Christie, 1974). Best values obtained were 420 ppm copper, 0.03 ppm gold, 99 ppm molybdenite, 2.1 ppm silver, and 91 ppm zinc.
Age: Tertiary or younger.
Alteration: Propylitic?
Commodities (Major) - Au, Cu; (Minor) - Ag, Mo, Zn
Development Status: None
Deposit Model: Creede epithermal veins? (Cox and Singer, 1986; model 25b)
