Ore body information

  • General form LINEAR, PINCH AND SWELL, LENS
    Strike NW
    Dip 33 S
    Thickness 3.05M

Comments on the geologic information

  • NITZE (1893) DESCRIBED THE DEPOSIT AS "...A BODY OF ORE, AND MIXED ORE AND GANGUE VARYING IN THICKNESS, AS VISIBLE AT PRESENT NEAR THE OUTCROP, FROM 5 TO 10 FEET, WITH A DIP OF ABOUT 33 DEGREES SOUTHWEST..." THE ORE IS DESCRIBED AS RESEMBLING "...THAT OF THE CRANBERRY MINE IN EVERY PARTICULAR."

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic
Significant No
Discovery year 1884
Year of first production 1884

Mining district

District name Cranberry Magnetite District

Workings at the site

  • Type of workings Surface/Underground
    Overall depth 12.19M

Comments on the workings information

  • BAYLEY (1923) NOTES THAT THE ONLY EVIDENCE OF MINING WAS SEVERAL LARGE DEPRESSIONS REPRESENTING THE OLD CUTS. NITZE (1893) STATED THAT THE WORKINGS INCLUDED A 40 - FOOT SHAFT, A CUT, AND A 15 - FOOT ADIT.

Comments on development

  • ECON.COM: THE MAGNETITE IS EASILY SEPARATED FROM GANGUE AND IS EXCEPTIONALLY LOW IN PHOSPHOROUS, TITANIUM, AND SULFUR.

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."
