Reference information

Comments Also reported 111 kt of Cu at 0.5% Cu; 50 kt of Mo at 0.12% Mo. Molybdenite–chalcopyrite mineralization of the deposit mainly occurs as veinlets in stockwork ore and dissemination in breccia ore (Zeng, Liu, Zhang and others, 2011). Latest Permian–Early Triassic age interval Cu-Mo or Mo mineralization that has not been previously recognized (Zeng, Liu, Zhang and others, 2011).
