Location: The Stibnite prospect is located above the confluence of Willow Creek and Cleary Creek; NE1/4NW1/4 sec. 25, T. 3 N., R. 1 E., of the Fairbanks Meridian.
Geology: By 1916, the Stibnite prospect was being explored by the Eldorado Mining and Milling Company and consisted of an open cut and a 40-foot shaft (Mertie, 1918). The 3- to 12-inch thick shear zone being developed contained 'commercial grade' lead and silver with minor gold. The principal metallic minerals identified were argentiferous galena, stibnite and pyrite. The ore is in quartzite and is parallel to the schistosity of the country rock.
