Deadwood Creek Prospect, Iditarod District, Yukon-Koyukuk Borough, Alaska, USA

Location: The Deadwood Creek placer deposit extends for about 1 mile northeast of the sharp bend at the head of Deadwood Creek about 5 miles above its mouth. The placer is at elevation of about 1,300 feet and extends diagonally across the E1/2 section 12, T. 30 N., R. 42 W., of the Seward Meridian. The location is accurate.
Geology: The Deadwood Creek prospect is an unexploited placer gold prospect with shallow overburden that was discovered in the 1930s but never mined (Toivo Rosander and Don Harris, oral communication, 1983). Fine-grained placer gold occurs in fluvial gravel layers, 3 to 10 feet thick, that are covered by 6 to 10 feet of overburden. The placer paystreak as outlined by churn drilling covers a area about 500 feet wide and a mile long. The gold-bearing paystreak is in alluvium of uncertain age (Bundtzen, Laird, and Lockwood, 1988; Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005). Placer gold has also been found in nearby Maybe Creek (ID083). In the early 1980s, a trail was constructed from Moore Creek (ID084) to bring mining equipment to the site and an airstrip was constructed.
Workings: The Deadwood Creek placer deposit was evaluated with a churn drill prior to World War II (Toivo Rosander and Don Harris, oral communication, 1983). In the early 1980s, a trail was constructed from Moore Creek (ID084) to bring mining equipment to the site and an airstrip was constructed.
Age: Probably Quaternary.
Production: Small amounts of placer gold were recovered during pit testing and during churn drilling (Toivo Rosander and Don Harris, oral communication, 1983).
Reserves: Not determined, but the placer was though to be economic in the 1980s.

Commodities (Major) - Au; (Minor) - Ag
Development Status: Yes; small
Deposit Model: Placer Au deposit (Cox and Singer, 1986; model 39a).
