KUNMING, Nov. 30 -- Southwest China's Yunnan province has increased its proven copper reserves by 700,000 metric tons (tonnes) and iron ore reserves by 5.6 million tonnes since 2007, according to the provincial land resources department.
It has also discovered 220,000 tonnes of lead and zinc reserves, 50,000 tonnes of tin reserves, and 250,000 tonnes of manganese ore.
Meanwhile, its lead mining project in Pu'er City made great breakthroughs this year. It not only fulfilled its target of finding 100,000 tonnes of lead and zinc reserves, but also discovered copper and molybdenum ore bodies, with resources estimated to top 500,000 tonnes.
Since the project started in 2007, the land resources department has invested 25.89 million yuan. It said that it would make further effort in the project to build a new copper and molybdenum resources base in Yunnan.
Yunnan is China's leading tin producer. Its other deposits include iron, coal, lead, copper, zinc, gold, mercury, silver, antimony and sulfur.
