Gejiu superlarge Sn-poly metal deposit is the important tin producing area in our country and world. But it has been faced with severe resource crisis in these years. A lot of data of geology, geochemistry and geophysics has been obtained through plenty of work. If these data can be used sufficiently, much of exploration fare could be saved. In the Gaosong Field, exploration work is not so sufficient as others while a lot of data, from geology, geochemistry, geophysics, etc, has been obtained. The synthesis information analysis and prediction method to predict mineral resource with the example of Gaosong field are used. In this method, quantified analysis is based on qualitative analysis. The two analysis methods can be combined .Once the qualitative laws are determined, the quantified analysis will be automatic and impersonal. First, information (such as geology, geochemistry, geophysics, etc) characters are gathered in the forms of quality from observation and research. Second, qualitative information (such as faults, folds, sedimentary, granite, and so on) is quantified and graded with the methods of statistics and geostatistics according to the qualitative characters. Third, the optimal unit is found with the method of fractal dimension method on the consideration of linear and facial factors. At last, information in the same type is synthesized with the grade self-similar adding information method based on Shannon information theory. Information in different types is also synthesized with the same grade self-similar adding information method．Some 18 prediction areas classified in 3 grades are found. These prediction areas sufficiently reflect the comprehensive metallogenetic laws of geology, geochemistry and geophysics. With the validation in the projects and known mines by Yunnan Tin Corporation, the effects are creditable.
