Chrisite (1974) typically does not mention quartz veins in his descriptions. If they are not present at this occurrence, their absence probably is significant with respect to potential for epithermal gold vein mineralization.
Location: Approximate location is on Bechevin Bay between mouth of Morzhovoi Bay and Traders Mountain. Anomaly no. 45 of Christie (1974) and no. 6 of MacKevett and Holloway (1977, p. 11).
Geology: Christie (1974) reported brief reconnaissance mapping of a color anomaly 2,000 by 3,000 ft, (600 by 900 m) covering a variety of volcanic rocks. The color anomaly is apparently due entirely to pervasive pyrite disseminated in all rock types. 99 percent of the pyrite is disseminated at concentrations up to 15 percent of the rock, and only rarely is it seen in fractures.
Workings: Brief reconnaissance geologic mapping and geochemical sampling reported by Christie (1974). Geochemical results showed copper typically less than 30 ppm and molybdenum less than 5 ppm; silver ranged from 0.9 to 1.6 ppm and gold was generally less than 0.01 ppm one sample yielded 0.02 ppm.
Age: Miocene or younger
Alteration: Propylitic alteration is common, as evidenced by chlorite and epidote. Rare sericitic alteration is locally present. Leaching is moderate and fracturing ranges from slight to intense.
