A large tin deposit was discovered in a mining zone in Chifeng, northern China's Inner Mongolia Autonomous Region recently, and 83,700 tons of tin has been proved. Its scale equals to two large tin deposits, according to Ministry of Land and Resources on May 18.

It is estimated that the potential economic value is more than 15 billion yuan. This discovery is expected to lead to China’s third production base of tin resources. The other two bases are located in Nanling Mountains which separate central China from south China and in Gejiu city, Yunan province respectively. 

Besides the 83,700 tons of tin, other metals such as molybdenum and copper were also discovered in the region.
