Based on the geological characteristics and exploration data of some major placer gold deposits in the northern part of northeast China and the experience in practical work, this paper puts forward some preliminary suggestions on the exploration network, the use of exploration wells, the determination of industrial indexes and the evaluation of the gold deposits in the old mining areas Opinions for discussion, the purpose is to determine the reasonable evaluation requirements according to the actual situation, so as to shorten the time and increase the reserves more, to do more with less, to obtain the best geological results.This paper after the completion of Cheng Cheng, Li Chengfan, Liu Xuesi, Engineer review, thank you.
