China Geological Survey Discovers Thick Concealed Rare-Earth Orebody in Sichuan-New Target Expands Mianning-Dechang Belt

Highlights

• Chinese geologists identified rare-earth mineralization buried under more than 100 meters of Quaternary sediment in Sichuan's Mianning-Dechang belt.
• The team combined time-frequency electromagnetic surveying with gamma-ray radiometric measurements to pinpoint drill targets in a previously inaccessible zone.
• No tonnage, grade, or resource estimate has been disclosed, meaning commercial significance remains unconfirmed pending further drilling and analysis.
• The discovery signals China's expanding exploration capability in mature districts, posing a strategic challenge for Western rare-earth supply diversification efforts.
