The U.S. Bureau of Mines rated this prospect as having low mineral development potential (Jansons and others, 1984).
Location: This prospect is on the east bank of Billings Creek at the terminus of Billings Glacier in the E1/2 section 29, T. 9 N., R. 5 E., of the Seward Meridian. This is location 134 of Condon and Cass (1958), location 57 of Cobb and Richter (1972), location 89 of MacKevett and Holloway (1977), location 139 of Cobb and Tysdal (1980), and location S-171 of Jansons and others (1984). This location is accurate to within a quarter of a mile.
Geology: This deposit consists of quartz veins in or near the sheared contacts between Tertiary dikes and Valdez Group slate of Late Cretaceous agen(Cobb and Tysdal, 1980). The dikes have been traced for several thousand feet along strike and are from 1.5 to 5 feet wide (Hoekzema and Sherman, 1983). Some portions of the dikes are highly altered, but the alteration is not described. Fractures in the dikes are recemented by quartz-carbonate veins containing arsenopyrite and small amounts of sphalerite, galena, and gold. The veins vary greatly in thickness, the widest measuring 8 inches (Johnson, 1914 [B 592-G, p. 234]). One quartz vein contained high tungsten values.
Workings: The prospect was discovered in 1912, and minor surface exploration was done at that time (Johnson, 1914 [B592-G, p. 234]). The U.S. Bureau of Mines examined and sampled the area in 1979, 1980, and 1981 (Hoekzema and Sherman, 1983). One grab sample of quartz contained 700 ppm tungsten. Anomalous gold values were found in Billings Creek.
Age: Tertiary or younger; the veins cut Tertiary dikes.
Alteration: Portions of the dikes are highlly altered, but the alteration is not described.
