General comments

Subject category Comment text
Deposit WOLFRAMITE HAS BEEN MINED FROM FOUR QUARTZ VEINS PRINCIPALLY. THIS DEPOSIT IS SIMILAR TO THE ONE AT SERRA DE SAO FRANCISCO ABOUT 85 KILOMETERS AIRLINE SW OF INHANDJARA, OF HYPOTHERMAL ORIGIN BUT WITH RYTHMIC EMPLACEMENT OF MINERALS, HIGH TO LOW TEMPEATURE. THIS WOULD APPEAR TO BE A TELESCOPED DEPOSIT.
