ShapshotThe Mt Weld Central Lanthanide Deposit (CLD) is one of the highest grade rare earth deposits in the world. Mt Weld also hosts the undeveloped Duncan (rare earth), Crown (niobium, tantalum, titanium, rare earths, zirconium) and Swan (phosphate) deposits.

Lynas processes the CLD ore at the Mt Weld Concentration Plant to produce a rare earth concentrate that is sent for further processing at Lynas Malaysia’s Advanced Material Plant near Kuantan, Malaysia.

The Mt Weld expansion will target feedstock production capacity of 12,000 tonnes per annum NdPr equivalent in 2024. Further capacity expansion in existing upstream and downstream production together with growth options for 2025 and beyond are being developed.

Deposit type

  • Carbonate hosted

Summary:

Mt Weld rare earth ore deposit occurs as supergene enriched mineralisation hosted in the Mt Weld Carbonatite regolith. The deposits have formed in the regolith profile of carbonatite with the rare earths concentrated by the removal of calcium, magnesium and other carbonate minerals during prolonged weathering process.

The Mount Weld rare earths deposits sit in a two billion year old volcanic plug. It is estimated that approximately 1.8km of the volcanic plug has been weathered during this time to form a high grade supergene Rare Earth Oxide (REO) deposit.

The Mt Weld Carbonatite (MWC) is a sub-vertical cylindrical igneous intrusion approximately 3.6 kilometres in diameter. The MWC is concealed under a 25m thick layer of younger transported alluvial sedimentary cover. Prior to the sedimentation, a prolonged widespread lateritic weathering process over the Laverton geological region has concentrated REE minerals in the carbonatite’s upper saprolite zone. The saprolite zone has variable thickness from about 80m to 120m below the surface.
