Deposit AUGUST 13, 1975: NOVEMBER, DECEMBER AND JANUARY HEAVY RAINS. THE MOST IMPORTANT COMPONENT OF THE ORE IS THE CRYPTOMELANE: NERAL, K(MN+4,MN+2)8 016. MONOCLINIC USUALLY MASSIVE. THIS M DOES NOT HAVE A CODE. HIGH GRADE BEDS OF MANGANESE OXIDE ARE LAYERED WITH BEDS OF MEDIUM-GRADEBANDED HEMATITE. THE LOWER LAYER OF THE MANGANESE ORE CROPS OUT, CONTINUOUSLY UGH SEVEN AND A HALF KM. ON THREE SIDES OF THE URUCUM HILL.
