Location: Aurora Creek is an east tributary of upper Cripple River; its mouth is about 5.5 miles upstream from where the Nome-Teller road crosses Cripple River. The location is in Aurora Creek at an elevationof about 600 feet and about half-way between the head of the creek and its mouth on Cripple River. It is the location of Kardex site Kx 52-294 (Heiner and Porter, 1972; Alaska Division of Geological and Geophysical Surveys, 1982). The location is about the center of a group of 15 claims staked in 1968.
Geology: A stratabound zinc-lead deposit (NM140) crops out in Aurora Creek about 1-mile above this location. Aurora Creek has been mined with hand tools for placer gold, especially in the benches on the southwest of Aurora Creek. Numerous boulders of zinc-bearing schist can be found along the stream. In 1968, Allan Doyle located 15 placer claims, nominally for zinc, along this part of Aurora Creek. One patented claim is within Doyle's claim block. This claim appears to have been located to control a head gate on a ditch rather than as a mineral location. Country rock is mainly the massive marble unit of Bundtzen and others (1994).
Workings: Fifteen claims were staked in 1968 during a period of activity on the Aurora Creek zinc-lead deposits (NM140). Some mining for placer gold has taken place along Aurora Creek and its west side benches.
Age: Quaternary.
Production: Probably very minor production of placer gold.
Commodities (Major) - Zn; (Minor) - Au
Deposit Model: Alluvial placer Au (Cox and Singer, 1986; model 39a); sphalerite-bearing boulde
