Comments on the workings information

  • THE WORKINGS ARE REPORTED (BAYLEY, 1923) TO BE DISTRIBUTED SO AS TO INDICATE A VEIN APPROXIMATELY 100 FEET WIDE. THE WORKINGS ARE OVERGROWN. THE ORE REPORTEDLY OCCURS IN TWO STREAKS 5 AND 6.5 FEET IN WIDTH.

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." ; INFO.SRC : 1 PUB LIT
