Aggie Creek

The Aggie Creek is a gold mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Exploration): Status = Inactive

Comment (Production): Production Notes = 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.

Comment (Workings): Workings / Exploration = 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).

Comment (Reference): Primary Reference = Miller and Grybeck, 1973

Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a).

Comment (Geology): Geologic Description = 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).

Comment (Geology): 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.
