In 2012, SRK inspected some multi-bench and bench-scale failures in the North and Central pits of this mine in Burkina Faso. The failure mechanism involved the interaction of foliation planes, basal planes and orthogonal joints. Also, daylighting of non-persistent basal planes interacting with steeply dipping westerly foliation planes which served as tension cracks or release surfaces, played a major role. An assessment of the hydrogeological parameters of the mine site was conducted before making recommendations for slope stability remedial work.
