'''Figure 1''' '''(a)''' Short tons of finished fluorspar produced by year from 1880 through 1995 in the Illinois portion of the Illinois-Kentucky Fluorspar District. No significant production has occurred in Illinois since 1995. Data were extracted mainly from ''Illinois Coal Reports'' (used courtesy of Illinois Department of Natural Resources) and U.S. Geological Survey (USGS) ''Minerals Yearbooks'' (used courtesy of the USGS). '''(b)''' Average grade of ore (% CaF<sub>2</sub>) processed in the Illinois-Kentucky Fluorspar District from 1925 to 1985. Average grade was calculated by dividing the tons of finished spar reported in the USGS Minerals Yearbooks '''(a)''' by the raw tons mined, which is reported in the Illinois Coal Reports. The grade is for CaF<sub>2</sub> only and does not take into account any credits for Pb or Zn, which would make a lower grade ore profitable, or stockpiling of ore. According to Ross Lillie, in the late 1970s, the average cutoff grade for Ozark Mahoning was typically 30% (CaF<sub>2</sub>), but if percentages of Zn, Pb, and sometimes Ba were high enough, the cutoff grade could be lowered. The red line shows that lower grade ore was being mined through time and indicates that 20% was about the lowest grade ore mined. An asterick (*) indicates a reporting error in one of the data sets for that year.  +
'''Figure 10''' Plan and cross section views of the Rose Creek Subdistrict near Herod, Illinois, circa 1953. Data from unpublished Ozark- Mahoning scanned documents. <br> (a) Plan view of the Rose Creek Mine underground workings and drill data. Red lines along drill holes indicate fault encountered. All holes were drilled on an angle. Holes within or from underground workings are dashed lines. All data from Minerva Oil Company files, circa 1953, contained in Ozark-Mahoning scanned files.<br> (b) Relationship of the hanging wall vein orebody to the main vein and the low-grade (15%–20% CaF<sub>2</sub>) orebody lying between the two veins, looking northeast along veins. High-grade ore is red; low-grade is stippled.<br> (c) Section showing ore reserves and underground mine workings along with ore reserve block as of 1953, looking northwest.  +
