Deposit	ORE OCCURS ON FAZENDA PEDRA DE AGUA ABOUT 17 KM, S40W FROM CITY OF ITABERABA. THE DEPOSIT IS VISIBLY DISSEMINATED IN A ZONE ABOUT 10-15 METERS LONG AND A FEW METERS WIDE IN HOST ROCK, BUT MAY BE LESS DISSEMINATED OVER OTHER AREAS. HOST IS STRONGLY FOLIATED N20-40E WITH STEEP DIPS. JOINTS ARE FILLED WITH QUARTZ. THE DEPOSIT OCCURS ON TOP OF A GRANITE EXFOLIATION DOME. THERE IS ONE SHORT ZONE ABOUT 30 CM WIDE IN WHICH MOLYBDENITE IS VISIBLE IN CRYSTALS 0.5 TO 2.0 CM IN DIAMETER. THE QUESTION WHETHER THE MOLYBDENITE IS DISSEMINATED THRU THE ENTIRE GRANITE DOME OR PRESENT ONLY WHERE SEEN IS NOT KNOWN. GEOCHEMICAL SAMPLING COULD TEST FOR THE DISSEMINATED MINERAL.
