Comments on the commodity information

  • Abundant Sulfides Rather Uniformily Distributed As Fine Grains and Aggregates. Deposit Exposed By Shallow Pit; Nickeliferous Sulfides In Prospect Pit Found Mostly In Massive Pyroxenite Rather Than Hypersthene; Most Sulfides In Mt. Prospect Area Found Mos
  • ABUNDANT SULFIDES RATHER UNIFORMILY DISTRIBUTED AS FINE GRAINS AND AGGREGATES. DEPOSIT EXPOSED BY SHALLOW PIT; NICKELIFEROUS SULFIDES IN PROSPECT PIT FOUND MOSTLY IN MASSIVE PYROXENITE RATHER THAN HYPERSTHENE; MOST SULFIDES IN MT. PROSPECT AREA FOUND MOSTLY IN LESS FELDSPATHIC NORITE.
