Abstract: The Zhugongtang lead-zinc deposit is located in the eastern part of the Sichuang-Yunnan-Guizhou Pb-Zn polymetallic metallogenic region. It is the first concealed super-large MVT lead-zinc deposit discovered in carbonate rocks of the Middle Permian Qixia Formation in the area after eight years of exploration (2013－2020). Based on the analysis of the metallogenic geological background, characteristics of the deposit, and the structural ore-controlling characteristics of the Zhugongtang area, we have believed that the Zhugongtang lead-zinc deposit was controlled by the Ziyun－Yadu thrust detachment structural system. The fracture-controlling is one of its basic characteristics. Through the systematic exploration, we have discovered the large sized concealed lead-zinc orebody with the lead-zinc resource of 3274400 tons, and have achieved the biggest breakthrough in the history of lead-zinc prospecting in Guizhou Province. The exploration practice of the Zhugongtang lead-zinc deposit has important guidance and reference values for prospecting lead-zinc resources in the northwestern Guizhou.
