Sanguikou Lead-Zinc Mine

In September 2023, the Sanguikou Zinc-Lead Mine obtained an integrated mining license covering both its southern and northern sections. This, together with the safety license obtained on October 20, 2025, for the low-grade pyrite-zinc polymetallic orebody in the Sanguikou section of the Dongshengmiao mine site, resolved the legacy issue of separate southern and northern operations. The mine currently has a mining and processing capacity of 10,000 tonnes per day and is one of China’s largest underground lead-zinc mines with the lowest ore grades.
