The molybdenum body occurs in the outer contact zone of a porphyry granite. The mining strata is mainly devonian system south bay formation and a small part sinian system要要that is the Xiaojiamiao rock formation in the later period of Ordovician system; It is constituted by the ductile shear belt from the County of Tongbai to Shangcheng; there are granite rock spots exposed on the surface of magmatic rocks and Jiujia Ridge concealed granite in the deep molybdenum elements are mainly Mo尧 W尧Cu尧Pb尧Zn and then Ag尧Bi尧Sn element zonal sequence (from top to bottom) are Cu-W-Mo-Ag-Pb-Zn-Bi-Sn.
