Location: This placer mine extends along the Tuluksak River for about 3 miles upstream from the mouth of Slate Creek. The area of placer mining is about 0.4 mile wide and continues upstream into the Russian Mission quadrangle. The map site is at the approximate midpoint of the workings in the Bethel quadrangle, at the northeast corner of section 6, T 10 N, R 60 W, of the Seward Meridian. It is locality 11 of Cobb (1972 [MF 455]) and of Hoare and Cobb (1977).
Geology: Extensive dredging has taken place onTuluksak River for about 3 miles upstream of the mouth of Slate Creek. The dredged area is up to 0.4 mile wide and it continues upstream into the Russian Mission quadrangle. Mining on this river started as early as 1909 and continued until 1964 (Hoare and Cobb, 1977). Some platinum was produced along with the gold. There have been some attempts to renew placer mining without apparent success. Copper mineralization in andesitic bedrock was dredged up locally (BH013). A significant part of the bedrock in the drainage is hornfels in Jurassic volcanic rocks surrounding a mid-Cretaceous pluton (Box and others, 1993).
Workings: Dredge tailings at least 3 miles long and up to 0.4 mile wide are present along the river. Ditches, flume, airstrip, buildings, and power line are shown on the USGS Bethel D-3 1:63,360-scale topographic map (1951/1971 edition).
Age: Quaternary.
