Comments on the geologic information

  • TACONITE ORE IN RANGE 16W IS CONFINED TO THE LOWER CHERTY MEMBER. MINERALOGY IS GENERALLY SIMILAR THROUGHOUT THE RANGE. THE OUTCROP WIDTH OF MAGNETITE TACONITE ORE RANGES FROM ABOUT 120 TO 457 METERS. THE DIP VARIES FROM ABOUT 3 TO 10 DEGREES. LENGTH AND WIDTH REFER TO THE ENTIRE BIWABIK FORMATION OF RANGE 16W. THICKNESS REFERS TO AVERAGE THICKNESS OF THE TACONITE UNITS OF RANGE 16W.
  • OTHER MINERALS PRESENT INCLUDE MINNESOTAITE, STILPNOMELANE, GREENALITE, AND SIDERITE.
  • HOST ROCK IS METASEDIMENT.
