The Wulagen Lead-Zinc Mine is an ultra-large, low-grade deposit in China that remained largely undeveloped for years due to poor resource conditions. After Zijin Mining became the operator of the project, it introduced a series of technological and management innovations, enabling large-scale development and effective resource recovery. The project has become China’s largest open-pit lead-zinc mine by production volume, with the lowest feed grades in the world. Its current processing capacity is 25,000 tonnes per day.

In 2021, additional resource discoveries at the mine were recognized as an “Outstanding Achievement of China’s Ten-Year Mineral Exploration Initiative” by the country’s Ministry of Natural Resources.
