Geophysical Contributions to Gold Exploration in Western Mali According to Airborne Electromagnetic Data Interpretations

The Birimian of West African Craton (WAC) is known for its gold potential. Among structures, N-S and NE-SW trends have been defined as controlling mineralizations in Kedougou-Kenieba Inlier (KKI), whereas some these structures are not gold-bearing. To determine related to mineralization, airborne electromagnetic data collected during the “Système Minier” Mali processed interpreted. Identified lineaments followed ground establish their link with showings Kenieba area. Geophysical interpretations show similarity different orders conductivity. They allowed characterizing resistance conductive prevalent directionalities. Conductive qualified good conductors strongly Artisanal Mining Sites (AMS). coincide tourmaline sandstones quartz-albite veins, which both often artisanally recognized indicators mineralization Western Mali.
