Location: This placer mine is on an unnamed tributary of the Slana River that is about 1.5 miles east of Alteration Creek (see Richter, 1967). The placer mine site is at an elevation of about 3,200 feet. It is in the NW1/4 section 12, T. 14 N., R. 6 E., Copper River Meridian. The mine location corresponds to locality 1 of Richter (1967) and locality 36 on figure 5 of Cobb (1979 [OFR 79-238]), placer locality 19 in table 3 of Nokleberg and others (1991), and probably is Kardex site number KX68-118 of Heiner and Porter (1972).
Geology: This placer mine is in a creek that drains granodiorite of probable Cretaceous age and Nikolai Greenstone of Late Triassic age (Richter and others, 1977). The Nikolai Greenstone has been metamorphosed to amphibolite near the Cretaceous (?) pluton. The creek was mined on a small scale. The gold reportedly was angular,. and Richter (1967) inferred that it was locally derived.
Workings: The mine was operated by Newt Peterson of Tok Junction possibly in the 1940's and 1950's (Richter (1967). The claims were restaked as the Genesee group by J. Frey in 1966 (Heiner and Porter, 1972).
Age: Holocene.
Alteration: Metamorphism of greenstone to amphibolite.
Production: Probably 100 ounces or less.
Commodities (Major) - Au
Development Status: Yes; small
Deposit Model: Placer Au (Cox and Singer, 1986; model 39a).
