    Barium-Barite BaSO4 50 wt-pct Barium Major 1972

Comments on the reserve resource information

  • DIFFICULTIES WITH THE FLOTATION PROCESS MAKE PRODUCTION OF ACID - GRADE FLUORSPAR AT A RESONABLE RECOVERY RATE IMPOSSIBLE AT THIS TIME (1972). ITEM 1 - CAMPBELL - MAC MILLAN VEIN. ITEM 2 - UPPER JOHNSON VEIN
  • ITEM 1 - CAMPBELL - MACMILLAN VEIN. ITEM 2 - UPPER JOHNSON VEIN

Comments on the workings information

  • DEPOSITS WERE MINED ON A SMALL SCALE FOR BARITE FROM 1890 - ? AND PRODUCED A SMALL AMOUNT OF FLUORSPAR FROM 1940 - 1949. CAMPBELL - MAC MILLAN VEIN IS 240 M. DEEP. JOHNSON VEIN IS UP TO 3 M. WIDE AT THE SURFACE AND WIDENS WITH DEPTH. IT IS OVER 210 M. DEEP.
  • KYANITE - GRAPHITE - MICA SCHISTS IN LAYERS 30 TO 60 FT. THICK IN NEARLY CIRCULAR BELT ABOUT 50 MI. IN CIRCUMFERENCE

Comments on development

  • ECON.COM: LOW GRADE OF ORE MAKES DEPOSITS UNECONOMIC AT THIS TIME (1972)
  • SEVERAL DEPOSITS WORKED 1932 - 1949

General comments

Subject category Comment text
Deposit VEINS ARE CONSIDERED HYDATOGENIC - HYDROTHERMAL IN ORIGIN. ELECTROMAGNETIC AND SOIL GEOCHEMICAL PROSPECTING METHODS HAVE BEEN MOST SUCCESSFUL. GRAVITATIONAL METHOD HAS NOT. 1100 M. OF DRILLING HAS PROBED THE CAMPBELL - MAC MILLAN AND UPPER JOHNSON VEINS.
Deposit DETAILED GEOLOGIC STUDY OF REGION IS DESIRABLE, BUT KYANITE DEPOSITS ARE NOT OF MUCH ECONOMIC IMPORTANCE ; INFO.SRC : 1 PUB LIT
