Studies have shown that the method of primary halo is most effective in geochemical prediction of ore deposit. It is playing an important role in following-up blind ore deposit and determining the position of orebody at different stages of exploration. The method is useful in guiding the evaluation of mineral occurrence and anomaly classify in ore zone periphery and regional ore belt. The prediction of mines in large and middle scale could be improved by this method. Furthermore,primary halos method can also provide geochemical evidence and basal material for studying the origin and controlling factors of the ore,the source of minerals,and the alteration of wall-rock.
