Abstract: Geostatistics is a new cross-discipline subject developed in the last 40 years. It was introduced into China in 1977 and attracted much attention. However it has not been widely applied because of the problems in programs of special software, on the basis of the theory of geostatistics, the researchers at Kunming University of Science and Technology programmed the software of Deposit Mathematics-Economy Modeling, which has been widely used in mines for its advantage and practicality. In this paper, the functions of each model of the software are discussed and its application is introduced by taking Jinbaoshan Pt-Pd deposit for example. With the models, ore reserves and mean grades are calculated.
