Abstract
The Far West Ble?da deposit is located in the buttonhole of Bou-Azzer El Graara at seven kilometers North West of the Ble?da mine. The geological formations of the study area are generally dipped to the north; they have more contacts at least faulted except diorites, which are intruded in basic rock. All these trainings are affected by both schistosities phases B1 and B2 of the orogeny panafricaine. The metamorphic grade increases from south to north marked by the development of metamorphic features represented in the north of the map. The mineralization of this area is cashed in green rocks (basalt) and also in diorites intrusions. Well, the gold of the study area is associated with the S1 and S2. Four paragenetics stages of gold were pointed out: i) Gold 1, disseminated in the matrix of the rock encased; ii) Gold 2, within quartz-veins; ii) Gold 3, within iron oxide and/or carbonate; iv) and Gold 4, within later calcite late. Gold 3 is associated to Palladium or Platinum. The mineralization is deposited in corridors shears, characterized by strong hydrothermal fluids percolate, which are associated with several types of hydrothermal alterations within mesothermal conditions.
