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.
Zijin Mining accumulated a 95% interest in the mine through multiple acquisitions since 2005.
The operation follows a local hiring strategy, with local employees accounting for 80% of its workforce. It maintains a strict approach to compliance, safety and environmental stewardship, working to build a green, eco-friendly mine. It implemented biodiversity conservation initiatives such as the protection of the wild blue sheep, and supports rural development programs such as grassland culture preservation, cattle farming facilities, and road improvements in Bolige Gacha.
Sanguikou has received recognition as a National High-tech Company and a National Worker Pioneer Entity. It has also been honored as a Green Plant and Green Mine in Inner Mongolia, and a Water-Saving Company in Bayannur City.
