Location: The Stibnite mine is located in the NW1/4SW1/4 sec. 32, T. 1 N., R. 2 W., Fairbanks Meridian. The Stibnite mine is near the head of the east fork of Eva Creek at an elevation of about 1,300 feet. It is about 1.6 miles north-northeast of the town of Ester. It is included in locality 14 of Cobb (1972 [MF 410]).
Geology: The Stibnite mine began producing ore as early as 1915 (Brooks, 1916 [B 642-A, p. 29]). Stibnite occurs in a shear zone as lenses, kidneys, and in granulary aggregates with some columnar masses; it is associated with iron-stained quartz veins and fragments of schist (Brooks, 1916 [B 649, p. 38-39]; Killeen and Mertie, 1951, p. 14-15). The shear zone trends N. 17 W. and dips 70-89 S.; the stibnite lenses pitch north (Killeen and Mertie, 1951). The largest lens of stibnite reported was 100 feet long, 7 feet wide, and 4 feet thick (Killeen and Mertie, 1951). In 1915 and 1926, about 300 tons of ore were produced from these large stibnite masses (Ebbley and Wright, 1948, p. 38; Killeen and Mertie, 1951). Shipments in 1915 contained 51.5 percent antimony (Killeen and Mertie, 1951). Killeen and Mertie considered the deposit to be mined out in 1951.
Workings: Ore was mined from open cuts and pits (Brooks, 1916 [B 649, p. 17]).
Alteration: Iron-stained quartz veins form the hanging wall (Brooks, 1916 [B 649]).
Production: In 1915 and 1926, about 300 tons of ore were produced from large stibnite masses (Ebbley and Wright, 1948, p. 38; Killeen and Mertie, 1951).
