The newly-found deposit sits at the foot of Mt. Laoyin in Longba Township of Zhuxi County, in Shiyan City, according to the Xinhua news agency. Zhushan, another county in Shiyan, has also been home to 12 rare earths discoveries. Local geologists are studying the most recent find to determine exactly what minerals can be extracted.
The rare earths designation is given to 17 chemical elements inlcuding dysprosium, terbium, thulium, lutetium and yttrium. China produces about 90% of the world's rare earth minerals. The Inner Mongolia Autonomous Region in north China has the largest reserves of rare earths in the country, or about 75%, according to Xinhua.
