The following is from: STATE OF MISSOURI GEOLOGICAL SURVEY AND WATER RESOURCES • BIENNIAL REPORT of the STATE GEOLOGIST (1943), Appendix VI, Manganese Deposits of Missouri, by Oliver R. Grawe.

"According to V. H. Hughes this property was prospected by John F. Church about 1917. A pit originally 10 feet long, 8 feet wide and 10 feet deep was blasted out of porphyry along a mineralized zone 3 to 4 feet wide at the crest of the mountain. Lower on the western slope, about 300 yards N. 85 W. is a second pit now about 5 feet in diameter and 3 feet deep. This likewise was dug on a mineralized zone about 2-1\2 feet wide, but traceable for only a few feet. The property was idle from 1917 to 1939, when N. Franks cleaned out the old pits. It is reported that Franks found three vertical mineralized fissures, one inch, three inches and four inches wide respectively in the wall of the upper pit."

"Fractures and joints in porphyry are filled with the hard, blackish gray, manganese mineral, braunite. These strike N. 25 E.- S. 25 W. Where the joints are close together the porphyry is largely replaced by ore and all gradations from solid ore to country rock may be observed. Small amounts of the typical hydrothermal mineral, alunite, occur as soft, pinkish microscopically crystalline aggregates, dispersed through the ore. This is an alteration product of the feldspar and is strong evidence in favor of the hydrothermal origin of the ore. A picked sample contained 50.75% manganese."
