The resource was estimated by several corporations. In order to meet the need of feasibility study, the resource was estimated again with geostatistics method by NERIN, and the estimated result was little different from those by the other corporations, which indicated that the estimated result was credible. Finally the resource was classified as measured and indicated according to the exploration works by exploration category. The case with geostatistics method was worth to be applied for deposit.
