Dime Creek

The Dime 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.

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

Comment (Workings): Workings / Exploration = The Dime Creek placers were mined intermittently from 1915 through at least the early 1990's. The deposits were worked mostly by drift and open-cut mining. A small dredge operated from 1931 to 1940.

Comment (Geology): Geologic Description = Dime Creek flows near a fault (?) contact between Paleozoic metalimestones and Jurassic-Cretaceous andesites. The andesites are intruded by small, mafic and ultramafic plutons. At the old placer mine, the gold is mainly on metamorphosed, andesite bedrock; some gold also is in the overlying 2 to 3 feet of gravel. In the stream bed the paystreak is well defined, while on the benches there are several, linear concentrations of gold. These bench concentrations were thought to be caused by wave action. Assays of gold from Dime Creek returned as high as 961 parts gold and 32 parts silver. The placers also contained platinum in approximate ratio to gold of 1:200. Analysis of platinum minerals from concentrate gave the following results: 88.8% Pt, I4.7% Ir, 4.3% Os + Ir, 1.1% Rh, 1.1% Pd (Mertie, 1969). The placer deposits in the upper portion of the creek produced almost twice as much platinum as the lower claims. On both creek and bench claims the overburden thickness ranges from 10 to 30 feet ; all of the ground was frozen. Heavy minerals in the concentrate from a second tier bench claim include iron-oxides, abundant chrome spinel, olivine, pyroxene, rare garnet, and rutile (Harrington, 1919).

Comment (Geology): Age = Quaternary.

Comment (Reference): Primary Reference = Harrington, 1919; Mertie, 1969

Comment (Production): Production Notes = On the lower end of Dime Creek, one ounce of platinum was produced for every 250 ounces of gold. On the upper claims there may have been as much as one ounce of platinum produced for every per 100 ounces of gold. A total of 35 ounces of platinum was recovered from placers at Dime Creek in 1917 (Harrington, 1919). Most of the 56 ounces of platinum reported from the Seward Peninsula in 1918 came from Dime Creek (Cathcart, 1920). Brooks and Martin (1921) report 32 ounces of platinum from the Dime Creek area.

Comment (Deposit): Other Comments = Stream gradient is approximately 50 feet per mile.
