Yu Wenli, member of the Political Consultative Conference of Liaoning Province and director of the Provincial Bureau of Geology and Mineral Exploration, told reporters at the Third Session of the 11th National People's Congress of Liaoning Province on the 21st that the large diamond mine is the only large diamond deposit found in China in the past 30 years. .
In 2009, the Liaoning geology and mineral exploration department discovered the diamond deposit during the mineral exploration in the Wafangdian area. After that, the mineral deposits were confirmed by drilling and other methods. According to the data currently available, the diamond was analyzed. The mine has a reserve of about 210,000 carats and is a large-scale diamond mine. This diamond mine can be mined for about 20 years at the current mining rate.
It is understood that China's diamond mines are mainly distributed in the Wafangdian area of ​​Dalian, Liaoning Province and Shandong Province, in which the diamond reserves in the Wafangdian area account for about 54% of the country.
Experts say that the diamond mines in the Wafangdian area are high-quality mineral deposits, with about 70% of diamonds above the gem level; Australia, which has the world's largest diamond reserves, is only five percent of the gem-grade.
