A scoping study, completed in early 2012, confirmed the potential to mine and process mixed sulphide and oxide ores at Lubembe. The Mineral Resource of 93 million tons at a grade of 1.9% copper will be mined by open pit methods, at a rate of 3.6Mtpa run of mine ore. The copper containing minerals, will first be recovered via the flotation method. In the second step of processing, the concentrate will be subjected to ferric and acid leaching to produce an electrolytic solution from which copper cathodes will be produced by electrowinning methods.
A pre-feasibility study will commence mid-2014 to determine the optimal processing option, to carry out detailed metallurgical testing and to commence baseline environmental fieldwork in the areas identified for waste rock dumping and tailings storage.
