Location and accuracy Stetson Creek is a north-flowing tributary of Cooper Creek that is located about 2 miles from the confluence of Cooper Creek and Kenai River. The placer section of the stream is about 1.5 miles long and is located in sections 8, 17, 18, and 19, of T. 4 N., R. 3 W., of the Seward Meridian, but most of the gold has been recovered at the map location in the SW1/4 section 8. This is location 24 of Cobb and Tysdal (1980) and location P-85 of Jansons and others (1984). This location is accurate to within a quarter of a mile.

Geologic setting

Geologic description

Stetson Creek occupies a steep, narrow valley with a bedrock gorge developed along its lower section. Bedrock is mapped as Valdez Group of Late Cretaceous age (Nelson and others, 1985). The placer section extends from the confluence of Stetson and Cooper Creeks upstream for about 1.5 miles (Tysdal, 1978 [MF-880-B]). Gravel deposited below a series of falls is reported to contain coarse gold (Jansons and others, 1984). Bench gravels along the lower creek just above its confluence with Cooper Creek are as much as 50 feet thick and moderately stratified and have a high clay content. In the 1950s high bench deposits near the confluence with Cooper Creek were hydraulically mined. Suction dredging has occurred sporadically since that time.
Total production is estimated to be less than 300 ounces of gold (Jansons and others, 1984). Two samples from the stream channel contained a trace to 0.0043 ounce of gold per cubic yard (Jansons and others, 1984).

Age of mineralization Quaternary; the gold is in the stream channel and in bench gravel.

Production and reserves

Workings or exploration Historically, work on this creek has consisted of small hydraulic operations and hand mining. In more recent time, small-scale suction dredges have worked the active stream channel. Gold recovered in the creek consists of both coarse nuggets as heavy as about 2 ounces and fine gold (Cobb and Tysdal, 1980). Total production is estimated to be less than 300 ounces of gold (Jansons and others, 1984). Two samples from the stream channel of Stetson Creek contained a trace to 0.0043 ounce of gold per cubic yard (Jansons and others, 1984).
Indication of production Yes; small
Production notes Cobb and Tysdal (1980) estimated total production from this creek as less than 769 fine ounces. Jansons and others (1985) estimated total production to be less than 300 ounces.
