Location: Cobb (1972, MF-413), loc. 22; SE1/4SW1/4 sec. 28, T. 3 N., R. 1 E., of the Fairbanks Meridian. This deposit is on the divide between Spruce and Little Eldorado Creeks at an elevation of about 1,600 feet. Accuracy is within 2,500 feet. The Hindenberg zone is now within the main orebody of the True North prospect (ARDF no. LG055).
Geology: The Hindenberg zone is now within the main orebody of the True North prospect (ARDF no. LG055). At least two veins have been worked for stibnite. One strikes N 40 E, dips 68 SE; and the other strikes N 65 E and dips 74 W. Hill (1933) described three shallow shafts on a vein that strikes about east. The ore on the dump is badly crushed, iron- and manganese-stained quartz carrying stibnite and arsenopyrite. Killeen and Mertie (1951), reported a sample of stibnite ore containing 57.76% Sb. The Hindenberg claim was worked for stibnite in 1916 and the Ohio claim was mined in 1918 (Mertie, 1918; Martin, 1920). Two hundred tons of ore was reported to have been shipped from the Hindenberg claim (Mertie, 1918). 16.5 tons of ore containing 38.5% Sb sold in 1942 (Joesting, 1943).
Workings: Over 500 feet of tunnel and other workings (Killeen and Mertie, 1951). In 1916, workings consisted of a shaft 25 feet deep, with drifts from the bottom (Mertie, 1918). The Hindenberg zone is now within the main orebody of the True North prospect (ARDF no. LG055).
Alteration: Quartz is iron and manganese stained.
Production: During WWI, two hundred tons of ore was reported to have been shipped from the Hindenberg claim (Mertie, 1918); 16.5 tons of ore containing 38.5% Sb were sold in 1942 (Joesting, 1943).
