These mines were located northeast of Lead Hill along an east–west-trending hill, which locally is called Spar Mountain. Numerous adits were driven into the hillside, and later, vertical shafts were constructed along the top of the hill to hoist ore from underground workings to the surface. Galena was mined at Spar Mountain around 1900 (Weller et al 1952). The Cleveland-Illinois Fluorspar Company developed the early mines. This company sold the galena and discarded the fluorspar (Bastin 1931). By 1919, with fluorspar in demand by steelmakers, the Spar Mountain Mining Company was operating the mines. Large-scale mining of these deposits began when the Spar Mountain Mining Company purchased mineral rights to the area (Weller et al. 1952). Fluorite was very pure in these early mines, and galena and sphalerite were present in restricted areas (Weller et al. 1952). The earliest mining methods were open pit and shallow drift mines into the hillside. In 1925, the Benzon Fluorspar Company assumed control of these operations (Bastin 1931). Currier (1944) stated that the Benzon Fluorspar Company properties extended along the east- and south-facing slopes of Spar Mountain from 1925 through 1939. The Austin Company, also called the Austin Mines Group, operated mines in the same area, including the West Morrison and Oxford Pits, the Lead Adit Mine or Lead Mine, the Cleveland and 32-Cut Mines, the Keeling Mine, and the Green-Defender Mine or Adit (Weller et al. 1952). Myers and Chenoweth (2009) indicated that the Austin Lead & Fluorspar Mine, Blue Valley Fluorspar Mine, Cleveland Lead & Fluorspar Mine, Defender Fluorspar Mine, East Green Fluorspar Mine, Green Fluorspar Mine, and Hillside Lead & Fluorspar Mines were all owned by the Austin Company.
