Comments on the geologic information

  • THE ORE OCCURS AS LENSES AND PODS IN DOLOMITIC LIMESTONE. THEY ARE HIGH-TEMPT METASOMATIC REPLACEMENT DEPOSITS, WITH AN UNUSUALLY HIGH FLUORITE CONTENT. STRUCTURALLY, THE ORE IS FOUND ON THE NORTH/SOUTH LIMBS OF A STEEPLY-DIPPING SYN- CLINE. THE FOOTWALL IS DOLOMITIC LIMESTONE, AND THE HANGING WALL IS A SLATE. IRON-ORE RESOURCES ARE 1.5 BILLION MT AT 35%. PRODUCTION IS 7.0 MILLION MTPY. THE IRON ORE IS PROCESSED LOCALLY INTO STEEL, AND THE RADIOACTIVE SLAG IS DUMPED IN SPECIAL AREAS. REO PRODUCTION IS A BYPRODUCT OF IRON PRODUCTION. THE REO OREBODY OCCURS AS A SEPARATE OPERATION FROM THE NEARBY IRON-ORE MINE. IT IS COMPOSED OF 800 MILLION MT OF ORE, CONTAINING 48 MILLION MT (6.0%) OF REO, AND 1.0 MILLION MT (0.13%) OF NIOBIUM. PRODUCTION IS IN THE RANGE OF 15,000 MTPY OF REO. IT IS THE LARGEST KNOWN BASTNAESITE DEPOSIT IN THE WORLD.
  • PRIMARY MINERALS ARE HEMATITE, MAGNETITE, MARTITE, BAST- NAESITE, MONAZITE, AND RUTILE.
