Mount Weld is a mine site in Western Australia, located about 30 km south of Laverton and 120 km east of Leonora.[1] It ranks as one of the richest major rare earth deposits in the world. [2] In addition to the rare earth oxide deposits, niobium and tantalum deposits are within the Mount Weld carbonatite, an intrusive pipe approximately three km in diameter.[3]
The main deposits are hosted within the soil/regolith horizon that blankets the entire carbonatite and form shallow lenses within 60 m of the surface. The most important rare earth oxide deposit, the Central Lanthanide Deposit, CLD, is located at the center of the carbonatite with the niobium/tantalum and other deposits generally located towards outer fringes. Discovered in 1988, the CLD represents a spectacular enrichment of rare earth deposit sediments. The deposit is believed to be the largest and highest grade of its type in the world.
