Location: Several occurrences are located on the west and northeast flanks of hill 2477, about midway between Casade Bay and Derickson Bay. The map site is in the SW1/4 section 2, T. 9 N., R. 9 E., of the Seward Meridian. This is location S-124 of Jansons and others (1984). This location is accurate to within a quarter of a mile.
Geology: The occurrences consist of several quartz-sulfide veins in the Contact Fault zone, a major regional structure that separates the Valdez Group of Cretaceous age from the Orca Group of Tertiary
Workings: The occurrences were discovered and sampled by the U.S. Bureau of Mines in 1981. Their samples contained as much as 0.13 ppm gold and 1.3 ppm silver, along with as much 2,600 ppm arsenic (Hoekzema and Sherman, 1983).
Age: Oligocene or younger; the Contact Fault cuts Oligocene intrusive rocks northeast of this occurrence.
Commodities (Major) - Au; (Minor) - Cu
Development Status: None
Deposit Model: Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)
