Location: The Willow Creek placer prospect is on a south-facing slope about 2.0 miles southeast of VABM Willow at an elevation of from about 1,200 to 1,500 feet. An approximate location is in the SW1/4 SW1/4, section 4, T. 29 N., R. 42 W., of the Seward Meridian.
Geology: Alluvial and residual placers on the hillside north of Willow creek are known from an elevation of about 1,200 to 1,500 feet where they were explored in 1958 (Don Harris, oral communication, 1983). No size or grade information is available. The prospect area is underlain by monzonite and the placer is possibly a residual placer over a lode deposit in the monzonite (Miller, Bundtzen, and Gray, 2005). Panned concentrates collected at the site contain gold, chromite, magnetite, and cinnabar (Bundtzen, Cox, and Veach, 1987; Bundtzen, Laird, and Lockwood, 1988).
Workings: Alluvial and residual placers on the hillside north of Willow creek are known from an elevation of about 1,200 to 1,500 feet where they were explored in 1958 (Don Harris, oral communication, 1983).

Panned concentrates were collected in the 1980's by the Alaska Division of Geological and Geophysical Surveys and the U.S. Geological Survey (Bundtzen, Cox, and Veach, 1987; Bundtzen, Laird, and Lockwood, 1988; McGimsey and others, 1988).
