Location and accuracy This lode occurrence is on the south side of the Tuluksak River, within an area of placer workings (BH014). The occurrence is in bedrock that was dredged during placer mining. The location is approximate. The map site is just inside the north boundary of section 5, T. 10 N., R. 60 W., of the Seward Meridian. It is locality 3 of Cobb (1972 [MF 455]) and of Hoare and Cobb (1977).

Geologic setting

Geologic description

Hoare and Coonrad (1959) reported that copper-bearing minerals had been observed in andesitic bedrock dredged from the base of the Tuluksak River placer deposit (BH014). They show a lode copper prospect approximately at this map site but the accuracy of this location is not known. Bedrock in the area is Jurassic andesitic and basaltic volcanic rocks (Box and others, 1993).
