Location and accuracy This location is on Idaho Creek, 3,000 to 4,500 feet north of its mouth on the Kuzitrin River, and 10,500 feet east of the Nome-Taylor road. It is locality 46 of Cobb (1972; MF 417).

Geologic setting

Geologic description

Gold colors are reported from an 18-foot deep test pit in stream gravels. The test pit, dug in 1899, did not reach bedrock and its digging was hampered by the presence of large rock fragments (Brooks and others, 1901). Sainsbury and others (1969) show 1,500 feet of the drainage to have been placer mined. This mine is near a regional fault contact between high grade metamorphic rocks and lower grade Lower Paleozoic metasedimentary rocks (Sainsbury and others, 1969; Till and others, 1986). Significant gold placers are spatially associated with the lower metamorphic grade, metasedimentary assemblage elsewhere on Seward Peninsula.

Production and reserves

Workings or exploration An 18-foot deep test pit was dug in 1899 to test the stream gravels. About 1,500 feet of the drainage has been placer mined from open cuts.
Indication of production None
