This deposit may be an extension of the veins at the Slate Creek No. 1 prospect (SR038) and Kenai Lu mine (SR035). All three veins are fault controlled and are nearly on strike (Martin and others, 1915).
Location: This ocurrence is located in the NW1/4 section 11, T. 9 N., R. 1 E., of the Seward Meridian. It is near sea level about a half-mile east of Slate Creek. This is location 17 of Cobb and Richter (1972), location 13 of MacKevett and Holloway (1977), location 4 of Cobb and Tysdal (1980), and location S-314 of Jansons and others (1984). The location is accurate to within a quarter of a mile.
Geology: This occurrence consists of fault-controlled quartz stringers in slate of the Valdez Group of Late Cretaceous age (Tysdal, 1978 [MF-880-A]; Hoekzema and Sherman, 1983). The quartz stringers are 1 to 2 inches wide. The fault zone is 4 feet wide, strikes N30E, and dips 60SE (Hoekzema and Sherman, 1983). Martin and others (1915) indicated that the vein strikes N70E and dips 70E. The quartz stringers carry arsenopyrite, chalcopyrite, galena, pyrite, sphalerite, and free gold (Moffit, 1905). The U.S. Bureau of Mines identified only minor pyrite and arsenopyrite (Hoekzema and Sherman, 1983). This deposit may be an extension of the veins at the Slate Creek No. 1 prospect (SR038) and Kenai Lu mine (SR035). All three veins are fault controlled and are nearly on strike (Martin and others, 1915).
Workings: There are no workings or improvements at this occurrence and no record of any production. The U.S. Bureau of Mines collected one chip sample in 1981; the sample assayed trace amounts of gold and silver (Jansons and others, 1984).
Age: Cretaceous or younger; the quartz stringers cut rocks of the Valdez Group of Late Cretaceous age.

Commodities (Major) - Au; (Minor) - Cu, Pb, Zn
Development Status: None
Deposit Model: Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)
