The reserves of 28# vein of Haigou gold deposit are more than 30 t��Geochemical study shows that the 12 trace elements related with gold mineralization can be divided into 5 metallogenic factors(element assembla- ges)��The high value area which FI��F2 and F4 together existed indicates the metallogenic halo overlaps in space with multiple stages of gold mineralization��and high mineralization potential in deep��The single high value area of 174 represents the location of ore body root��while the high values of F3 and F5 show the high value areas belong to intervals of baden sectors��Comprehensive geochemical studies show the high prospection potential below the 14th section between 39-71 lines of 28# vein��not only the known ore body has further extension��but also may have appearence of new concealed ore body in deep��It is necessary to do prospecting for the mineralization below the lOth Ievel between 15-29 lines��
