Baoxinggou area is located in northern Daxing'anling． In this area， comprehensive use of geophysical and geochemical exploration methods plays an important role in the prospecting，and has yielded some applica- tion results so far． Based on the 1/100 000 stream sediment anomaly survey， the methods of 1/20 000 soil geo- chemical measurement，trenching engineering on the earth's surface and 1/10 000 IP intermediate gradient survey were all used to verify and decompose drainage anomalies，as well as to find and locate ore bodies． In this way，an effective，economical and quick prospecting method was concluded，which focuses on the middle and lower mountain forest swamp landscape in the northern part of Daxing'anling，and provides reference for the prospecting in the area．
