The mineralogical and metallurgical testwork, which was supervised and managedby independent consultants Tetra Tech was carried out on 350kg of drill corerepresentative of both lode and stockwork ore grade material with a 10 per centdilution factor with a grade similar to that expected for run of mine. The testwork results indicated fast oxidation kinetics, achieving over 90 percent oxidation for both lode and stockwork concentrate samples. Maximum goldextractions achieved were 90.4 per cent and 87.1 per cent respectively withoverall recoveries confirmed by Tetra Tech to be in line with their independentScoping Study. BIOX®, which is a well established bacterial oxidation technique, wasrecommended by Tetra Tech as an appropriate technology for treating the goldsulphide concentrate at the proposed gold mine at Clontibret. BIOX®is anenvironmentally friendly proven technology with a number of plants in operationworldwide including South Africa, Ghana, Brazil, China and Australia.
