The Eldorado 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 (Workings): Workings / Exploration = Mines in the area were drift or open cuts. Most mining occurred between 1915 and 1919.
Comment (Reference): Primary Reference = Harrington, 1919
Comment (Deposit): Other Comments = Although placer gold was first discovered on Little Eldorado Creek, the richest placer ground was on Dime Creek. Stream gradient approximately 50 feet per mile.
Comment (Geology): Geologic Description = Placer claims were staked in 1915 after gold was discovered near the mouth of [Little] Eldorado Creek. The creek follows the probable faulted contact between Paleozoic slate and limestone and Mesozoic andesitic volcanics. (Also see Dime Creek, ARDF number CA002).
Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a).
Comment (Production): Production Notes = In 1915, the production from 3 claims was said to be $3,000 (gold at $20.67/ounce). In 1916 the total production from Eldorado and Dime Creeks totaled about $100,000 from 8 claims; total production from 16 claims in 1917 was $150,000 (Harrington, 1919).
Comment (Geology): Age = Quaternary.
