| Abstract: | The gibbsite deposits in central Guangxi Province are the unique large-scale gibbsite deposits in China with mineral resources of 770 million tons confirmed initially. This paper presents the applications of the geostatistics method to exploration and resource evaluation of this deposit, including the calculation and fitting of the variograms of typical gibbsite deposits, determining the best exploration project spacing using the variograms; automatic classification of resources and estimation of resource amount. |

| Keywords: | gibbsite geostatistics variogram exploration and evaluation estimation of resource |
