DELINEATION OF PROSPECTING TARGET BY GEOCHEMICAL SURVEY:The Discovery of the Daxintun Antimony-Gold Deposit in Heihe, Heilongjiang Province

The Daxintun antimony-gold deposit is located in the northeast of the Daxinganling metallogenic belt, with frequent tectonic and magmatic activities. The Sb, Au, Ag and Hg anomalies in stream sediments are high and in large scale. This area is the favorable metallogenic position for gold and polymetal. In order to assess the of stream sediment anomalies, the 07Hs-35 anomaly is chosen to be verified by soil geochemical survey method. With the soil geochemical survey, some anomalies of Sb, Au, Hg, Ag, As and W are delineated, among which Sb, Hg and Au anomalies are dominated. The concentration centers of each element are essentially coincident. The delineated soil geochemical anomalies are then confirmed by trenching, with the finding of antimony-gold orebodies. The Daxingtun antimony-gold ore prospecting target is successfully established.
