The final mineralogical and metallurgical testwork results were analysed andevaluated by Tetra Tech in advance of an anticipated prefeasibility study (PFS)enabling Tetra Tech to confirm the preliminary estimates for the processingplant. The review of the metallurgical testwork results confirmed the key processdesign parameters, including the amenability of the ore to bio-oxidativepre-treatment, and the suitability of the proposed BIOX® oxidation process.Other than a lower sulphur grade in concentrate, results were as anticipated inthe PEA. The decreased sulphur grade implies savings in both capital andoperating costs.
