【Chifeng, Inner Mongolia: The "Lithium" Dream and "Tin" Hope of Mineral Exploration Breakthrough】
The Weilasituo lithium polymetallic mine in Chifeng City, Keshiketeng Banner, Inner Mongolia, has now identified a total ore volume of approximately 280 million mt, with a lithium oxide metal content of 1.9 million mt and an average lithium oxide deposit grade of 0.65%. The tin metal content is 122,000 mt, with an average grade of 0.94%. The deposit features shallow burial (exposed at the surface), thick ore bodies (300-650 meters), large resource reserves (equivalent to nearly 20 standard large lithium mines), and high grades (3-4 times that of the Yichun region in Jiangxi). The proposed mining method involves initial open-pit mining followed by underground mining. Open-pit mining offers advantages such as a short infrastructure construction period, rapid results, high safety levels, large-scale extraction, high mechanization, high resource utilization rates, low mining costs, low ore dilution and loss rates, low safety management difficulty, and low energy consumption.
