Origin of Material
The Frontier deposit is in the DRC on the east flank of the Kafue anticline, ~30km southeast of Mufulira. The deposit occurs within shales in the upper portions of the Mwashya Subgroup and within the base of the Nguba Group. The deposit is structurally controlled with sulfides in veins and irregular replacements adjacent to a major recumbent fold nucleated along the originally normal faults
Approximate Mineral and Chemical Composition
The orebody consists of a complex network of stockwork to breccia veins that contain an assemblage of dolomite-quartz-chalcopyrite ± bornite.
