Slide 20: ANIT Metallurgical Upgrading Results
ANIT Metallurgical Upgrading Results Much of the mineralized material from the ANIT can be significantly upgraded by wet screening to remove coarse pebbles that contain little or no uranium mineralization. Upgrading could substantially lower processing and transportation costs, allowing development
Slide 21: Classification
Classification “Bajos” occurrences are “Surficial-type” – with differences 1. Calcrete is minor but gypsum is abundant. 2. “Basement” rocks are Mesozoic clastic sedimentary rocks, not Precambrian granites and gneisses. 3. Fossils in the host sediments suggest an arid but not a desert environment. 4.
Slide 22: Genesis
Genesis 1. Deposits formed under semi-arid conditions by groundwater. Devitrification of acid tuffs and weathering of the tuffs and felsic intrusives constitute a huge source of uranium in groundwater. 2. No obvious “basement” source of vanadium. However black magnetite-rich heavy mineral accumulati

Economic Potential Finally Metallurgical tests on ANIT mineralization showed significant upgrading by wet screening through removal of unmineralized coarse pebbles. Upgrading could significantly reduce processing and transportation costs and make the development of several satellite deposits utilizi
