Abstract: The Tapinggou copper-molybdenum deposit, located in the north section of the Daxinganling polymetallic metallogenic province, is of porphyry type discovered in recent years. The deposit is medium-sized, buried in the depth of 34.6 m and more, with orebodies dominated by Mo in sulfide minerals. The Cu-Mo deposit is composed of ten molybdenum orebodies and one copper body. The grade of molybdenum ranges from 0.071% to 0.268%. The maximum extension of orebody is 930 m, with the thickest monolayer of 106.89 m. The metal content is preliminarily estimated in excess of 20000 tons.
