China's Largest Lead Mine Discovered In Yunnan Province

Following years of exploration efforts, China's largest lead-zinc mine was recently discovered in Lanping Bai and Pumi Autonomous County of Nujiang Lisu Autonomous Prefecture in Yunnan Province.

Its lead and zinc metal reserves are over 15 million tons with a potential value expected to surpass 200 billion yuan. Based on the current extraction speed, it can be mined for 100 years.

The lead-zinc mine is located 18 kilometers northwest of the county seat of Lanping Bai and Pumi Autonomous County, with a confirmed reserve of 15.4761 million tons of lead and zinc metal, and a combined grade of lead and zinc reaching 9.44 percent.

Lead-zinc mines mainly adopt surface mining techniques therefore the extraction cost is low. Currently in Lanping, the surface mining capacity of oxidized ore is 1,500 to 2,000 tons a day, and that of sulphide ore is around 2,000 tons a day.
