Comments on the geologic information

  • GEOLOGY THE BATESVILLE DISTRICT IS ON THE SOUTHERN EDGE OF THE OZARK PLATEAU, AND IS UNDERLAIN BY SEDIMENTARY SANDSTONES, SHALES, LIMESTONES, AND CHERTS OF ORDOVICIAN, SILURIAN, DEVONIAN, AND CARBONIFEROUS AGE THAT HAVE UNDERGONE LITTLE DEFORMATION. THE ROCKS IN THE DISTRICT DIP SLIGHTLY TO THE SOUTH, DUE TO THE GENERAL DOMING OF THE ROOMS IN THE OZARK PLATEAU. THE GENERAL TREND IS OBSCURED LOCALLY BY MINOR FOLDS AND NORMAL FAULT DISPLACEMENTS; THE SYNCLINAL FEATURES, BASIN AREAS. THE FOLDS ARE ALIGNED NORTHEAST, AND THE SERIES OF NORMAL FAULTS TRENDS EAST-WEST. MANGANESE DEPOSITS ARE CONCENTRATED IN STRUCTURAL LOWS, WHILE STRUCTURAL HIGHS ARE NEARLY BARREN. LITHOLOGY THE BOONE CHERT FORMATION CAPS MOST OF THE HILLS IN THE DISTRICT. THE MAJOR DEPOSITS OCCUR IN THE FERNVALE LIMESTONE AND IN THE CASON SHALE WHICH REST UNCOMFORTABLY ABOVE IT. THE BOONE FORMATION OFTEN RESTS DIRECTLY ON THE CASON SHALE, OR ON THE FERNVALE LIMESTONE WHERE THE SHALE IS ABSENT. THE FERNVALE LIMESTONE IS A COARSE-GRAINED MASSIVE, CROSS-BEDDED, DARK GRAY OR PINKISH GRAY LIMESTONE WHICH IS FRIABLE IN EXPOSED LEDGES. THE LIMESTONE REACHES A MAXIMUM THICKNESS OF 125 FT(38M) AT THE WESTERN BOUNDARY OF THE MANGANESE DISTRICT AND THINS OUT EASTWARD. THE AVERAGE THICKNESS OF THE FERNVALE IS 100 FT (30M). MANGANESE AND IRON OXIDES AND CARBONATES OCCUR FAIRLY UNIFORM IN THE UPPER 10-50 FT (3-15M) OF THE LIMESTONE, AND ARE CONCENTRATED IN ITS RESIDUAL DAYS. THE CASON SHALE IS A LENTICULAR, PHOSPHATE, GREENISH- GRAY SHALE WHICH AVERAGES ABOUT 5 FT(1.5M) THICK. THE COM- POSITION OF THE SHALE VARIES GREATLY, BUT IN SOME LOCALITIES IT CONTAINS VERY HIGH GRADE MANGANESE.THIS SHALE CONTAINS A LAYER, GENERALLY A FEW FEET THICK, OF YELLOWISH SANDSTONE WHICH OUTCROPS AS LEDGES. THESE LEDGES ARE USED AS MARKERS BY PROSPECTORS, AS MANGANESE ORES ARE COMMONLY FOUND BELOW THEM.
  • MINERALS PRIMARY MANGANESE MINERALIZATION IS BELIEVED TO HAVE BEEN DEPOSITED AS CARBONATES AND OXIDES OF MANGANESE IN THE BATESVILLE DISTRICT BY CIRCULATING HYPOGENE SOLUTIONS IN TOP HEADS OF THE FERNVALE AND CASON SHALE. THE PRIMARY MINERALS INCLUDE HAUSMANITE, BRAUNITE, RHODOCHROSITE AND OTHER CARBONITES FOUND DISSEMINATED IN UNALTERED OR SLIGHTY ALTERED REPLACEMENT DEPOSITS. THE MANGANESE MIN- ERALIZATION IS MOST HEAVILY CONCENTRATED IN THE CASON SHALE AND IN THE UPPER 10-50 FT(3-15M) OF THE FERNVALE LIMESTONE.

Comments on exploration

  • EXPLORATION ALL MANGANESE PRODUCTION CAME FROM AREAS WHERE THE MANGANESE CONCENTRATIONS IN ERODED SYNCLINAL TROUGHS WHERE THE BOONE CHERT HAD BEEN WEAKENED AND BROKEN BY WEATHERING AND FOLDING, AND THE UNDERLYING MANGANIFEROUS FERNVALE AND CASON FORMATIONS HAD BEEN EXPOSED. RAY STROUD (SEE BIBLIO GRAPHY), USBM ARKANSAS STATE LIAISON OFFICER, BELIEVES THA THERE ARE OTHER ENRICHED OR CONCENTRATED MANGANESE DEPOSITS IN SYNCLINAL TROUGHS OVERLAIN BY THE BOONE CHERT. TAILED GEOLOGICAL MAPPING IN THE DIST. FOR THESE TROUGHS COULD LOCATE DRILLING TARGETS FOR THESE INFERRED ENRICH- ED MANGANESE DEPOSITS. ALSO A MAGNETOMETER MAY BE A USEFU TOOL TO LOCATE FERRUGINOUS MANGANESE DEPOSITS OVERLAIN BY THE BOONE CHERT.

Comments on the production information

  • PRODUCTION HISTORY ACCOUNTING FOR MUCH OF THE ORE PRODUCED IN THE DISTRICT ARE DEPOSITS IN RESIDUAL CLAYS AND TALUS, RESULTING FROM EROSION OF SECONDARY OXIDE DEPOSITS IN AREAS WHERE BOONE CHERT AND OTHER CAP ROCKS HAVE BEEN REMOVED, RESULT- IN IN VERTICAL SLUMPAGE AND DOWNSLOPE CREEP OF THE DEPO- SITS.

Comments on the reserve resource information

  • QUANTITY-GRADE RESOURCE ESTIMATES FOR THE BATESVILLE MAGANIFEROUS CARBONATE (MANGANESE CARBONATE) DEPOSITS HAVE BEEN COMBINED. INFERRED RESERVES WERE ESTIMATED BY STROUD (BU MINES RI 6478, P.23) IN 1963. ESTIMATES OF MANGANIFEROUS LIMESTONE TONNAGES AND GRADES WERE BASED ON THE LENGTH AND THICKNESS OF OURCROPS DRILL HOLE INTERSECTIONS, AND THE MANGANESE CONTENT OF SAMPLES. IN DETERMINING THE SIZE OF AREAS BELIEVED TO BE UNDERLAIN BY MANGANIFEROUS LIMESTONE, EXPOSURES WERE ASSUMED TO INFLUENCE WIDTHS EQUAL TO 1/2 THEIR OBSERVABLE LENGTHS. EXCEPT IN INSTANCES WHERE PLANE TABLE MAPPING AND DRILL HOLE PERMITTED THE USE OF MORE EXACT INFORMATION. REVISION IN ESTIMATIONS WERE MADE FOR AREAS WHERE BARREN ZONES WERE FOUND BY POST-1956 CHURN AND CORE DRILLING. AVERAGE MEASURED THICKNESSES WERE USED TO CALCULATE VOLUME. A FACTOR OF 14 AV. FT. PER LONG DRY TON (0.358 M E /DRY MTON), WAS USED IN CALCULATING TONNAGES. THE INFERRED RESOURCES WERE BASED UPON DATA GATHERED IN THE FIELD ON MORE THAN 580 SEPARATE TRAITS USING MANGANESE CUT-OFF GRADES OF 2%. THERE IS A MAP OF ALL KNOWN OCCURANCES OF THE BATES- VILLE DISTRICT MANGAFEROUS LIMESTONE DEPOSITS THAT ALSO INCLUDE MAGANESE OXIDE OCCURANCES ON FILE AT THE BU MINES IFOC HEADQUARTERS FILE SEQUENCE NUMBER 0050630256. THE PHOSPHATE CONTAINED IN THE MANGANESE ORE IS DELETERIOUS.
