Location: The Gold Creek (Eagle Bluff) prospect consists of lode claims adjacent to Gold Creek, a tributary to Butte Creek. The map site is at an elevation of about 3,700 feet, on the north valley wall of Gold Creek. It is in the northwest corner of sec. 18, T. 21 S., R. 1 W., of the Fairbanks Meridian. The accuracy of the location is within 1,500 feet. This is location B-9 of Balen (1990: 34-90), and location 159 of Kurtak and others (1992).
Geology: The country rocks in the area of this prospect are Eocene(?) granodiorite and Lower Cretaceous to Upper Jurassic metamorphosed turbidites (Wilson and others, 1998). The prospect has been described as a silicified fault zone containing chalcopyrite, molybdenite, and arsenopyrite(?). Rock chip samples contain 0.25 ounce of gold per ton, 0.57% copper, 71 ppm molybdenum, and high values of bismuth and silver (Balen, 1991).
Workings: Surface exploration only.
Age: Early Tertiary(?).
Alteration: Alteration consists of narrow phyllic and silicified zones.
Commodities (Major) - Ag, Au
Development Status: None
Deposit Model: Polymetallic veins or low-sulfide Au-quartz veins (Cox and Singer, 1986; model
