  Caption: Figure 10 Plan and cross section views of the Rose Creek Subdistrict near Herod, Illinois, circa 1953. Data from unpublished Ozark- Mahoning scanned documents.
  (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.
  (b) Relationship of the hanging wall vein orebody to the main vein and the low-grade (15%–20% CaF₂) orebody lying between the two veins, looking northeast along veins. High-grade ore is red; low-grade is stippled.
  (c) Section showing ore reserves and underground mine workings along with ore reserve block as of 1953, looking northwest.
