Location: This placer mine is located in section 3, T. 10 N., R. 2 E., of the Seward Meridian. The creek occupies a fairly wide and gentle U-shaped valley along most of its length but flows through a short, steep bedrock canyon near its junction with Glacier Creek. This is location 134 of Cobb and Richter (1972), location 181 of MacKevett and Holloway (1977), location 4 of Tysdal (1978 [MF-880-B]), location 134 of Cobb and Tysdal (1980), and location P-94 of Jansons and others (1984). This location is accurate to within 300 feet.
Geology: Bedrock in the Winner Creek drainage is sedimentary rock of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). The deposits in the stream channel consist of well-stratified and washed alluvium; local bench deposits consist of clay-rich, cemented glacial or fluvial-glacial gravels. The gravels contain some quartz diorite cobbles (Park, 1933). The clay-rich gravels contained fairly coarse (three-sixteenths of an inch) gold at one sample site (Jansons and others, 1984).
Workings: A hand placer and hydraulic operation recovered gold from stream and bench gravels between 1898 and 1917 (Tysdal, 1978 [MF-880-B]). Since then hand placer methods and suction dredges have been used sporadically (Jansons and others, 1984). The U.S. Bureau of Mines collected samples on lower Winner Creek (Jansons and others, 1984). Alluvium from the active stream channel contained 0.002 ounce of gold per cubic yard; the bench gravels contained 0.0283 ounce of gold per cubic yard. Samples collected from the upper and middle portions of Winner Creek contained trace amounts of gold.
Age: Quaternary.
Production: The total estimated production, from the lower quarter-mile of the creek, is 400 ounces, of which less than 25 ounces has been produced since 1975 (Jansons and others, 1984).
