•A world-class orogenic gold deposit in the Paleoproterozoic Baoulé-Mossi domain of the West African Craton•Structurally controlled continuous gold mineralization over 5 km-long•Polycyclic deformation events resulting in multiple mineralized episodes•Large hydrothermal alteration halo extending more than 50 m away from gold mineralization
The world-class > 4 Moz Wona-Kona gold deposit is hosted within the Paleoproterozoic Birimian Houndé greenstone belt which is the most important gold mineralized belt in the western part of Burkina Faso, with a cumulative reserve of ~ 11 Moz. The mineralization consists of a pervasive silicification with disseminated pyrite–arsenopyrite crosscut by quartz–carbonate veinlets (1 to 10 cm wide) forming a vertical, thick (up to 40 m) and laterally extensive (5 km) northeast trending orebody hosted within a large (200 m wide) shear zone of regional extent. Gold occurs in association with 3 generations of pyrite and 2 generations of arsenopyrite. Free gold, interpreted as the last mineralizing event, occurs as late fracture filling in the pervasive silicification zone.
