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 15.24M

Comments on the geologic information

  • BAYLEY (1923) STATES THAT THE ORE FRAGMENTS ON THE DUMP CONTAIN VERY RICH, COARSE MAGNETITE LIKE THE LATE ORE AT THE CRANBERRY MINE. THE MAGNETITE OCCURS AS IRREGULAR MASSES BETWEEN AND LOCALLY SURROUNDING LARGE ANHEDRAL GRAINS OF PYROXENE. EPIDOTE OCCURS AS SPARSE BUT LARGE GRAINS AND AS SECONDARY VEINLETS IN THE MAGNETITE. VEINS OR FRACTURE FILLINGS OF QUARTZ AND CALCITE CUT THE VEIN MATERIAL.

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic
Significant No
Discovery year 1692
Year of first production 1692

Mining district

District name Cranberry Magnetite District

Ownership information

  • Type Operator
    Owner Magnetic Coal And Iron Co.

Workings at the site

  • Type of workings Surface
    Overall length 182.88M
    Overall width 15.24M

Comments on the workings information

  • BAYLEY (1923) STATES THAT ABOUT ONE - THIRD THE WIDTH OF THE VEIN WAS LEAN ORE.

Comments on development

  • THE MINE HAS BEEN WORKED INTERMITTENTLY SINCE BEFORE 1800. THE MINE SUPPLIED ORE TO THE DOE RIVER FORGE AROUND 1885, AND IN 1898 IT WAS REOPENED BY THE CRAB ORCHARD IRON CO. FOR A BRIEF TIME. IN 1917, THE MINE WAS PROSPECTED BY THE MAGNETIC IRON & COAL CO. WITH UNSATISFACTORY RESULTS. ; 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." ; INFO.SRC : 1 PUB LIT
