They are: 1) porphyry type of Au(-Cu) deposit or Au-bearing porphyry type of Cu deposit; 2) epithermal type of Au-Ag and Au-Te deposit; 3) fine-disseminated type of Au-sulfide-quartz deposit; and 4) porphyry type of Cu or Cu-Mo deposit. In addition, some suggestions are proposed for further regional geological survey and prospecting.
