Abstract: This Cu-polymetallic deposit is found recently during the mineral prospect survey in the Daxinanling metallogenic province. Systematic analysis on the ore-forming geologic background shows that the basement of the region is the Boketu-Duobaoshan island arc, superimposed by large scaled Mesozoic magmatic intrusions and volcanic eruptions, with good ore-forming conditions. The result of 1:200 000 geochemical survey indicates a Cu-Au-Mo metallogenic prospect. The investigation involving region geological survey, stream sediment survey, high precision magnetic measurement and 1:10 000 soil geochemical survey discovers the Cu-polymetallic deposit of skarn type with great potential.
