Comments on the commodity information

  • HIGH-GRADE ORE OCCURS AS MASSIVE IRON SULFIDE BANDS. WHERE EXPOSED, THESE BANDS WHERE OXIDIZED AT SURFACE TO LIMONITE, BUT WHEN PIECES BROKEN OPEN, FOUND TO CONSIST ENTIRELY OF UNALTERED SULFIDES. ON OXIDIZED FACES MAY BE SEEN OCCASIONAL SPECKS OF CUPRITE.
