Location and accuracy This placer mine is located in SE1/4 section 20, T. 5 N., R. 2 W., of the Seward Meridian. Hargood Creek (named by the mine owner and not shown on the 1976 revised C-8 quadrangle) is about one-quarter mile northwest of and parallel to Crescent Creek. It flows west into Quartz Creek, which flows into Kenai Lake near Cooper Landing. This is location P-82 of Jansons and others (1984). This location is accurate to within a quarter of a mile.

Geologic setting

Geologic description

Hargood Creek occupies an abandoned channel in a narrow valley, possibly formerly occupied by a stream draining a lateral moraine or esker. Lower Hargood Creek has developed a braided stream channel fan that is truncated by Quartz Creek (Jansons and others, 1984). Gold has been concentrated by reworking of glacial-fluvial sediments; it is concentrated within certain horizons within each braided stream channel. The gold occurs both in active and abandoned channels and as flakes and small nuggets less than three-sixteenths of an inch (Jansons and others, 1984).
The local bedrock is Valdez Group of Late Cretaceous age (Nelson and others, 1985).

Production and reserves

Workings or exploration
An old hydraulic excavation is present on the alluvial fan just south of Crescent Creek trailhead. A small mechanized operation tested the alluvial fan gravels in 1981 and 1982 (Jansons and others, 1984). More recently, there has been some suction dredging (C.S. Huber, oral communication, 1999).
The U.S. Bureau of Mines collected three samples from the mouth of the creek that yielded 0.0004 to 0.0315 ounce of gold per cubic yard. The sample size is unknown (Jansons and others, 1984).
Indication of production Yes; small
Reserve estimates The volume of the alluvial fan gravels is estimated to exceed 350,000 cubic yards (Jansons and others, 1984). No estimates of grade are available.
Production notes The U.S. Bureau of Mines estimated the production at less than 350 ounces of gold, of which as much as 150 ounces have been produced since 1980 (Jansons and others, 1984).
