Geologic structures

Type Description Terms
Regional Northwesterly
Local Granite Becomes Less Platy And Interfoliated Gneisses Become Less Abundant As Distance From Vein Increases.

Ore body information

  • General form LENS, PINCH AND SWELL
    Dip SW
    Thickness 2.9M

Comments on the geologic information

  • BAYLEY (1923) NOTES THE OCCURRENCE OF A LARGE PEGMATIVE VEIN AT THE HARDIGRAVES OPENING, BUT COULD NOT DETERMINE IF IT CUT THE MAGNETITE ORE.

District name Cranberry Magnetite District

Comments on the workings information

  • ON THE ELLERS PROPERTY, ONE OF THREE OPENINGS IS A SHAFT. BAYLEY (1923) STATES THAT NO BEDROCK WAS EXPOSED AT THE TIME OF HIS VISIT; MINERS PROVIDED SCANT DETAILS ABOUT THE VEIN.

Comments on development

  • SOME DEVELOPMENT WORK WAS BEING DONE AROUND 1919. ; ECON.COM: THE MAGNETITE IS EASILY SEPARATED FROM GANGUE AND IS EXCEPTIONALLY LOW IN PHOSPHOROUS, TITANIUM, AND SULFUR.

Subject category Comment text
Deposit ACCORDING TO BAYLEY (1923), "THE VEINS IN WHICH THE ORE OCCURS COMPRISE MORE OR LESS BANDED MIXTURES OF PEGMATITE, EPIDOTIC GNEISSES, HORNBLENDE SCHISTS AND LENTICULAR MASSES OF A MIXTURE OF HORNBLENDE AND MAGNETITE, IN PLACES CUT BY SMALL VEINS OF MAGNETITE."
