Location: The prospect is located in the SW1/4 section 29, T. 8 N., R. 1 W., of the Seward Meridian, at an elevation of 3,100 feet. It is situated about 4,000 feet north of Frenchy Creek. This is location 29 of Tysdal (1978 [MF-880-A]) and location S-276 of Jansons and others (1984). This location is accurate to within a quarter of a mile.
Geology: Nelson and others (1985) have mapped the bedrock in this area as undifferentiated sedimentary rocks of the Valdez Group of Late Cretaceous age. The deposit consists of several quartz veins of undetermined thickness; these strike N70W and dip steeply south. The vein contains arsenopyrite, pyrite, sphalerite, and gold (Tysdal, 1978 [MF-880-A]). The U.S. Bureau of Mines sampled this prospect in 1979; they collected one grab sample that assayed a trace of gold and 0.02 ounce of silver per ton (Jansons and others, 1984).
Workings: Workings consist of several prospect pits, and improvements consist of a trail. The U.S. Bureau of Mines sampled the prospect in 1979. They collected a grab sample that assayed a trace of gold and 0.02 ounce of silver per ton (Jansons and others, 1984).
Age: Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.
