Abstract
The Mary Arnold Mining Co. in 194.3 owned 292 acre s of mineral land in Christian County, Mo., and was one of two companies with milling facilities in southern-central Missouri. Production from this property between 19.37 and 1941 amounted to 1,718 tons of zinc in the form of zinc concentrate. Because of the urgent war requirements for additional zinc and the existing facilities for treatment of zinc-lead ores at these mines, in the winter of 1943-44, the Bureau of Mines investigated the deposits by churn drilling in an endeavor to outline enough ore to maintain production of zinc from this district. Five holes aggregating 1,043 feet were bored.
