Huangbuling gold deposit is one of the main mining areas of Canzhuang gold deposit��and the exploitation of gold mining has been more than 1. 6 t�� The authors forecast deep seated orebody location for crisis mines using primary halo geochemistry to solve the problem of inadequate reserves�� The study of correlation of indicator elements��elements combination��and spatial distribution charactrisitics of elements contents for primary halo geochemistry of vein No. 7 in Huangbuling gold deposit shows that the high values of factor scores F4 and F5 can be used as the signs of the upper part of orebody�� The high values of cumulative index ( Hg /Ni) can be used as the sign for the upper part of orebody��and otherwise as the lower part�� The study has also evaluated the ore-bearing of deep orebody��and blocked out three target areas��
