Metallogenic conditions and prospecting potential of the Henglu mining area in the Zhuxi ore concentration area

The Henglu mining area is located in the Zhuxi ore concentration area, and its metallogenic conditions are similar to those of the Zhuxi ore deposit, the world's largest tungsten deposit. Many prospecting clues have been found in the 500 m in shallow so far, and it is urgent to explore the deep ore-searching prospect in this area. Comprehensive analysis from geological, geophysical, geochemical, remote sensing characteristics and drilling verification, we found that the metallogenic conditions, such as oreforming strata, rock and ore controlling structures and diagene-metallogenic events in magmatic rocks, are very similar to those in Zhuxi mining area. In addition, the distribution of superficial mineralization alteration in Henglu mining area is closely related to the dike, the physicochemical anomaly and dike distribution in Henglu mining area indicate the existence of concealed magmatic body. Based on this, the authors consider that the Henglu area has the potential to find structural fracture zone (hydrothermal vein), skarn and porphyry copper-molybdenum -gold polymetallic deposits.
