Daqingnanshan Gold Deposit is located in the north of Heilongjiang Province,an important base in China of nonferrous and precious metals and energy mineral resources.Based on systematic summary of existing data,the geolo-gical characteristics of Daqingnanshan Gold Deposit are studied in detail.There are 7 orebodies delineated in the mining area.The orebodies occur in alkali feldspar granite and are distributed in veins and thin veins to NE direction under the control of NE trending fault (tectonic alteration zone).The ore types are mainly gold-bearing pyrite vein type and beresite type.Wall rock alteration mainly includes potassium alteration,silicification,sericitization,chloritization,etc.The type of deposit is medium-low temperature hydrothermal filling quartz vein type gold deposit.By comparing the typical gold deposits with similar metallogenic characteristics in the area,it is considered that the deep part of the mining area has good exploration potential,and the deep area with good exploration potential is verified through drilling,pit exploration and other exploration projects.The results show that the Ⅱ-1 orebody is further controlled in the deep part of the mining area,and the Ⅲ orebody and V orebody are detected.The total reserve of gold ores (332 ＋ 333) is 494 399 t,the reserve of gold metal is 2 399 kg,and the average grade of gold is 4.85×10-6,showing good prospecting effect.Through deep exploration in the mining area,good exploration results are obtained,providing support for further exploration in the mining area.
