With discussion on the metallogenic characteristics, distribution and research progress of the Au-Cu-Mo deposits on both sides of 1 ns = "urn:schemas-microsoft-com:office:smarttags" />1:PlaceName w:st="on">Erguna1:PlaceName> 1:PlaceType w:st="on">River1:PlaceType> and the upper reaches of 1:place w:st="on">1:PlaceName w:st="on">Heilongjiang1:PlaceName> 1:PlaceType w:st="on">River1:PlaceType>1:place>, the commercial types with the most prospecting potential are concluded. 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.
