The Bikkuri reef area that is located to the north of Shaft 1, contains Mineral Resources that were previously reported in the 2013 Mineral Resource update, while the Bikkuri reef area that is located southeast of Shaft 1, was identified during the revised geological interpretation. Indicated Mineral Resources for the Bikkuri reef total seven million tonnes at a grade of 2.81 g/t 3PE+Au, 0.35% nickel and 0.19% copper and occur solely in the north area. Inferred Mineral Resources for the Bikkuri reef total 27 million tonnes at a grade of 2.72 g/t 3PE+Au, 0.30% nickel and 0.16% copper (see Table 3). The 2.0 g/t 3PE + Au grade shell used in the estimation of the Mineral Resource averages 5.7 metres in thickness in the Indicated Mineral Resources area. The continuity of FW mineralization has been modelled based on limited drill data, as not all of the UMT drill holes extended into the FW. For this reason, estimation of Mineral Resources has been restricted to the northwestern area of the Platreef Project where drill spacing is in the order of 100 metres to 200 metres. Similar mineralization has been seen in drill holes across the entire Platreef Project, but the current drill spacing is insufficient to define Mineral Resources amenable to selective mining methods in these areas. This represents exploration upside for the Platreef Project.
