Daying uranium mine in Inner Mongolia (Tarangaole mining area in Hanggin Banner, Ordos), which was invested and implemented by the Central Geological Exploration Fund, made a major breakthrough in uranium exploration in Daying area in central Inner Mongolia, and found the largest in-situ leachable sandstone-type uranium deposit in China. The cumulative control of uranium resources in this area ranks among the world-class large mines. This is of great significance to improve the supply of uranium resources and the ability to ensure the development of nuclear power resources in China.
