Economic information

Geologic structures

Type of structure Local
Structure description Granite Becomes Less Platy And Interfoliated Gneisses Become Less Abundant As Distance From Vein Increases.

Ore body information

  • General form PINCH AND SWELL, LENS
    Width 0.3M

Comments on the geologic information

  • THE WORKINGS ARE DESCRIBED AS BEING IN "...A VEIN OF EPIDOTIZED PEGMATITE CONTAINING A ONE FOOT WIDE MAGNETIC SEAM." THE EXPOSURES "...ABOUT A MILE WEST OF LITTLE ROCK KNOB" ARE DESCRIBED (BAYLEY, 1923) AS LIKE THOSE AT THE CRANBERRY MINE.

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic
Significant No
Discovery year 1887

Mining district

District name Cranberry Magnetite District

Ownership information

  • Type Operator
    Owner J. R. Englebert

Comments on the workings information

  • WORKINGS ARE DESCRIBED AS A CUT AND A SMALL TUNNEL. OTHER WORKINGS WEST OF LITTLE ROCK KNOB REPORTEDLY UNCOVERED A LARGE ORE BODY, ACCORDING TO BAYLEY (1923), WHO STATES THAT ONLY A FEW PITS AND PILES OF ORE CAN BE SEEN, WITH OTHER VISIBLE EVIDENCE OF THE VEIN LACKING. EXPOSURES AND MAGNETIC ANOMALIES WEST OF THE KNOB ARE SAID TO EXTEND ALONG AN EAST - WEST BELT FOR ABOUT 4,000 FEET.

Comments on development

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