The prospect is in Denali National Park and Preserve.
Location: The Eldorado prospect is at an elevation of about 1800 feet, on the north wall of the canyon of Eldorado Creek. It is about 0.3 mile east of the center of section 22, T.16S., R.18W., Fairbanks Meridian. The location is accurate. The prospect is number 37 of Hawley and Associates (1978), 13 of Thornsberry, McKee, and Salisbury (1984), and 13 of Bundtzen (1981).
Geology: This prospect consists of a poorly exposed quartz-carbonate vein about 2 feet thick that strikes approximately northeast and cuts muscovitic marble of uncertain affiliation. The vein contains pyrite and stibnite; kermesite and stibiconite occur as secondary coatings on weathered vein material. The marble is silicified and brecciated. A 2-foot sample across the vein contained 3.2 percent antimony; a selected sample assayed 14.1 percent antimony and 0.81 ounce of silver per ton (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, v. 2, number 13).
Workings: The vein is poorly exposed. It was discovered and staked by prospector-miner Jim Fuksa.
Age: The deposit is assumed to be Eocene (see record MM091).
Alteration: Oxidation of antimony minerals.

Commodities (Major) - Sb; (Minor) - Ag
Development Status: None
Deposit Model: Simple stibnite deposit (Cox and Singer, 1986; model 27d).
