Metallurgical test work programs have been undertaken on a range of representative composites of drill core samples, evaluating flowsheet options and reagent regimes to assess the metallurgical performance of the ores.
All ores tested have exhibited excellent flotation characteristics with rapid float times, very high recoveries and production of a high-quality concentrate.
Comminution test work showed the material was consistent with regards to comminution characteristics between the two deposits and that the material was moderately hard and competent but amendable to conventional comminution methods.
All ores were found to respond very well to conventional flotation practices. The ore is not considered complex with almost all sulphides being copper (chalcopyrite) or iron-based minerals (pyrite).
