Comments on the geologic information

  • THE MINERALIZED BED IS ESTIMATED TO HAVE AN AVERAGE THICKNESS OF 15 METERS IN THE PYROXENITIC BELT, AND FROM 3 TO 5 METERS IN THE SERPENTINITIC BELT. IT HAS A LENGTH OF 800 TO 2,000 METERS. THE NIQUELANDIA DEPOSITS ARE TYPICAL NICKEL LATERITE ORE BODIES DEVELOPED BY WEATHERING OF AN ULTRAMAFIC INTRUSIVE HOST ROCK.
