Abstract: The GIS-based weight of evidence (WofE) method was adopted for metallogenic prediction of new-type ore deposits. At first, the research situation of new-type mineral resources was introduced, and then a study case was made on the evaluation of new-type ore deposits in the central southern section of Daxing'anling. Based on the establishment of geological minerals spatial database, the weights of evidence prediction model was built and two forecast prospects were delineated by using GIS techniques, analyzing the unusual metallogenic information including mineral geology, geophysics, geochemistry and studying the relationship of the geological abnormal and mineralization with multi-science. The results of research showed that this method was effective and practical in the metallogenic prediction of new ore deposits, thus providing a scientific basis for the further exploration and development of the mineral resources in the study.
