Location: Aggie Creek is a south tributary to Fish River. Open-cut placer workings from hydraulic operations and some dredging, are present about 12 miles east of Council. These workings are between elevations of about 40 and 140 feet on the main channel and extend a distance of 1.7 miles starting 0.3 miles upstream from the mouth of Aggie Creek. This is locality 125 of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: Open-cut placer workings, from hydraulic operations and some dredging, are present on the main channel over a distance of 1.7 miles starting 0.3 miles upstream of the mouth of Aggie Creek. These workings are between elevations of about 40 and 140 feet. Bedrock of the Aggie Creek drainage is schistose Ordovician chlorite marble (Till and others, 1986). Miller and Grybeck (1973) note that quartz latite porphyry intrusives, like those present to the east, could be present in the Aggie Creek drainage and may be gold-bearing as at ARDF locality SO147. Copper concentrations in stream sediment samples are slightly elevated throughout the Aggie Creek drainage (Miller and Grybeck, 1973). Quartz latite intrusive rocks of the region are assumed to be mid-Cretaceous in age, the age of the Kachauik pluton. A K/Ar age for the Kachauik pluton is 86.1 +/- 3 Ma (Miller and others, 1972).
Workings: Open-cut placer workings, from hydraulic operations and some dredging, are present on the main channel over a distance of 1.7 miles starting 0.3 miles upstream of the mouth of Aggie Creek. This mining took place between 1929 and 1941 (Cobb, 1978). Dredging was reported for the years 1939 to 1941; this was apparently on the lower part of the creek; where large boulders were encountered (Smith, 1939, B 917-A).
Age: Quaternary; the placer deposits are in the active channel of Aggie Creek. This area is at low enough elevations to have been influenced by Quaternary sea level changes.
Production: Lu and others (1968) report that $101,604 worth of gold (about 3,000 ounces at $35.00 per ounce) were produced from Aggie Creek.

Commodities (Major) - Au
Development Status: None
Deposit Model: Placer Au-PGE (Cox and Singer, 1986; model 39a).
