Economic information

Comments on the geologic information

  • THE IRON-FORMATION IS BOUNDED BY FINE-GRAINED SCHISTS AND PHYLLITE. THE IRON-FORMATION VARIES FROM THIN TO THICK BEDDED AND IS COMPOSED OF FINE-GRAINED, CHERTY QUARTZ AND MAGNETITE WITH SOME HEMATITE, AND IN SOME LAYERS, CHLORITE AND GARNET.

Reserves and resources

  • Type In-situ
    Estimate year 1978
    Total resources 71000mt ore
    Commodity Subtype Grade units Group Importance Year
    Iron Fe 15 wt-pct Iron Major 1978

Comments on the reserve resource information

  • IT IS ESTIMATED THAT 160,000,000 LT OF CRUDE ORE WOULD YIELD ABOUT 45,000,000 LT OF CONCENTRATES.

Comments on the workings information

  • THE MAGNETITE DEPOSIT OCCURS AS A BELT OF PRECAMBRIAN IRON-FORMATION FROM 500 TO 1,000 FT WIDE AND ABOUT 14,000 FT LONG. IT DIPS NEARLY VERTICALLY RANGING FROM 80 DEGREES BOTH NORTH AND SOUTH. MINING WOULD BE BY OPEN PIT AND CONCENTRATION BY MAGNETIC SEPARATION AFTER FINE GRINDING.

Comments on development

  • ECON.COM: MOST OF THE DEPOSIT IS ON LAND OWNED BY ASHLAND COUNTY AND IS LEASED TO ASHLAND MINING CO., WHICH IS CONTROLLED BY MCLOUTH STEEL CORP. (1978).
