Overview
The Lynas Malaysia advanced materials plant is located on a 100-hectare site in the Gebeng Industrial Estate. It processes mixed rare earth carbonate (MREC) from the Kalgoorlie facility and concentrate from the Mount Weld mine.
Production
Production overview - 2024: rare earth elements 5655 t; 2023: rare earth elements 6142 t.
Processing
The Lynas Malaysia advanced materials plant is located on a 100-hectare site in the Gebeng Industrial Estate. It processes mixed rare earth carbonate (MREC) from the Kalgoorlie facility and concentrate from the Mount Weld mine. The process involves three main stages: cracking and leaching, solvent extraction, and product finishing. In the cracking and leaching stage, the concentrate is mixed with sulphuric acid and heated to convert rare earth phosphates to sulphates. Water is then used to leach the rare earth sulphates, and impurities are removed. The solvent extraction stage uses a liquid-liquid counter-current system to separate the rare earths into individual elements or groups. Finally, in product finishing, the separated rare earth elements are precipitated as solid carbonates or oxalates and then calcined to produce the respective oxides.
Expansion
In October 2023, a variation to the Malaysian operating licence was granted, allowing the continuation of cracking and leaching activities at the facility. A major works program was completed in December 2023 to increase the production capacity for the NdPr family of elements to approximately 10,500 tonnes per annum. This program also involved reconfiguring a solvent extraction circuit to enable the production of Dysprosium and Terbium, with first production targeted for the 2025 calendar year. Lynas is also planning a new heavy rare earths separation facility at the Malaysian plant with a target processing capacity of up to 5,000 tonnes per annum of HRE feedstock. The initial phase of this new facility is expected to produce Samarium from Mt Weld feedstock by April 2026.

Overview
The Kalgoorlie Rare Earths Processing Facility, operated by Lynas Rare Earths Ltd, is a first-of-its-kind downstream processing plant in Australia. It undertakes value-added processing of rare earth concentrate from the Mt Weld mine. The facility produces a Mixed Rare Earths Carbonate (MREC), which is then shipped to Lynas' Malaysian facility for final separation into individual rare earth products, and in the future will also supply a planned US facility. The plant is a key component of Lynas' 2025 growth plan. First production of MREC commenced in the June 2024 quarter, with the first shipment to Malaysia also occurring during this period. The facility was officially opened on 8 November 2024.
Production
For the period of June 2024 to 31 December 2024, the facility processed 11,986.6 dry metric tonnes of rare earth concentrate. During this same period, the facility produced 24,738.2 dry metric tonnes of gypsum by-product and 8,613.9 dry metric tonnes of iron phosphate by-product.
Processing
The processing at the Kalgoorlie facility involves a cracking and leaching process. Rare earth concentrate from the Mt Weld mine is mixed with concentrated sulphuric acid and treated at a high temperature in a 110-metre long, 6-metre high rotating kiln. This process converts the rare earth phosphate minerals into rare earth sulphate. Water is then added in a leaching stage to dissolve the rare earth sulphates, and impurities, primarily in the form of iron phosphate, are removed. The resulting solution is neutralised to produce the Mixed Rare Earths Carbonate (MREC). The facility also includes a waste gas treatment plant to clean gases from the kiln before they are released as steam through a 65-metre tall stack.
Expansion
The facility is ramping up production, which is being managed to align with increased capacity at the Mt Weld mine and the Lynas Malaysia plant, as well as market demand. In early November 2025, production was impacted by significant power supply disruptions. Lynas is developing plans for an off-grid power solution to ensure energy stability.

Overview
The Wicheeda Rare Earth Project is a 100%-owned Defense Metals Corp. development asset in British Columbia, approximately 80 kilometres northeast of Prince George. The project hosts a carbonatite-related rare earth deposit with Measured and Indicated resources of 29.2 million tonnes at 2.27% TREO and Inferred resources of 5.5 million tonnes at 1.42% TREO, inclusive of reserves. A 2025 pre-feasibility study supports a proposed open pit development with a 15-year mine life. Wicheeda benefits from road access, nearby power, gas pipeline and rail infrastructure and is advancing through feasibility-stage drilling, environmental work and metallurgical studies. Wicheeda is a rare earth-enriched carbonatite system hosted within a syenite-carbonatite intrusive complex. Defense Metals describes the deposit as a southeast-trending, north to northeast-dipping intrusive complex with dimensions of approximately 450 metres north-south by 250 metres east-west, intruding mixed sedimentary host rocks. The higher-grade mineralisation is mainly associated with dolomite-carbonatite rocks, which outcrop at surface and form the main body of rare earth mineralisation.
Production
Wicheeda is not in production. It is an advanced development project moving through feasibility-stage work, environmental baseline studies, metallurgical pilot work and additional drilling. On May 6, 2026, Defense Metals announced that spring 2026 core drilling had started after field mobilisation was completed on May 1, 2026. The program is expected to comprise 6,865 metres, including pit slope geotechnical drilling, waste rock geochemical drilling and resource upgrade/infill drilling.

Overview
Pela Ema is Serra Verde’s ionic clay rare earth mine and processing operation near Minaçu in Goiás and is one of the most strategically significant rare earth projects outside Asia. The operation entered commercial production in early 2024 and is the first scaled producer outside Asia of the four key magnetic rare earths dysprosium, terbium, neodymium and praseodymium. Its geology supports low-impact open-pit mining and processing without blasting, crushing, milling or wet tailings. The operation is run by Serra Verde Pesquisa e Mineração (SVPM) within the Serra Verde Group. USA Rare Earth announced on 20 April 2026 that it had agreed to acquire 100% of Serra Verde Group, subject to closing, which would place Pela Ema within the combined USAR group if completed.
Production
The mine entered commercial production in early 2024. Serra Verde says the operation is expected to produce about 6,500 tonnes of rare earth oxides per year by the end of 2027 over a 25-year mine life. Its 2024 sustainability review also said Phase I was ramping toward at least 5,000 tonnes per year of rare earth oxides.
Expansion
Serra Verde is ramping Phase I toward nameplate production and evaluating a Phase II expansion that could double run-of-mine output before the end of the decade.

Workforce
approximately 100 direct jobs when fully operational (expected). The facility is expected to create approximately 100 direct jobs when fully operational.
Overview
A planned facility in Seadrift, Texas, for separating both heavy and light rare earth elements. The project is a collaboration with the U.S. Department of Defense (DoD) to strengthen the U.S. rare earths supply chain. Feedstock for the facility is intended to be sourced from the Lynas Mt Weld mine and Kalgoorlie Rare Earths Processing Facility in Western Australia. However, as of early 2026, there is significant uncertainty regarding the construction of the facility due to unresolved wastewater permit issues and ongoing negotiations for a mutually acceptable offtake agreement with the DoD.
Production
The plant was initially expected to produce approximately 5,000 tonnes per annum of rare earth products, including about 1,250 tonnes per annum of NdPr, and 2,500-3,000 tonnes per annum of heavy rare earth products.
Processing
The facility is designed for the co-location of integrated Heavy Rare Earths and Light Rare Earth separation plants. It will process mixed rare earths sourced from Lynas' operations in Western Australia.
Expansion
Lynas has completed the purchase of a 149-acre greenfield site in Seadrift, Texas, from Union Carbide Corporation, a subsidiary of The Dow Chemical Company. The U.S. Government has allocated approximately US$258 million for the construction of the Heavy Rare Earths component of the facility. An additional US$30 million in matched funding from the DoD was allocated for the light rare earth separation plant. The facility is targeted to be operational in FY2026 (1 July 2025 - 30 June 2026). However, recent reports indicate significant uncertainty about the project proceeding, with wastewater management being a key issue. In March 2026, Lynas signed a binding Letter of Intent with the U.S. government for a rare earth oxide supply agreement, which intends to re-allocate approximately US$96 million, previously designated for the Texas facility's construction, to the purchase of light and heavy rare earth oxides from Lynas' existing facilities over a four-year period. This followed a mutual decision to modify the original agreement due to the uncertainty surrounding the construction of the Seadrift facility. An interview with the Lynas CEO in May 2026 confirmed the significant uncertainty as to whether the plant in Texas will proceed, and if so, in what form.

The plant is comprised of three main processing areas: cracking and leaching, solvent extraction, and product finishing. The cracking and leaching process, which generates Water Leach Purification (WLP) residue, is a key part of the operations. As part of a recent license renewal, Lynas is required to cease the production of new WLP radioactive residue by March 2, 2031. Any WLP generated between March 2026 and March 2031 must undergo thorium extraction to reduce its radioactivity.
Expansion
In March 2026, the Malaysian government renewed the operating license for the Lynas Advanced Materials Plant for 10 years. This renewal is subject to strict conditions, including the cessation of radioactive waste production by 2031. Any radioactive waste generated in the five years leading up to 2031 must be neutralized through methods such as thorium extraction. No new permanent disposal facility for this waste will be permitted. Lynas is also required to contribute 1% of its annual gross sales to research and development funds for Malaysia's domestic rare earths industry. In October 2025, Lynas announced a significant investment to establish a dedicated heavy rare earth processing facility in Malaysia. There are also plans for a partnership with the South Korean firm JS Link to produce super magnets at a neighbouring site.

Production
For H1 FY2026, total Rare Earth Oxide (REO) production was 6,375 tonnes, with Neodymium and Praseodymium (NdPr) production at 3,407 tonnes. Mt Weld achieved record NdPr in concentrate production in FY2025.
Processing
Ore from the Mt Weld deposit is processed on-site at the concentration plant through crushing, grinding, flotation, and filtration to produce a mixed rare earths concentrate. This concentrate is then transported to Lynas's Kalgoorlie facility or Lynas Malaysia refinery for further processing.
Expansion
Lynas Rare Earths is undertaking a significant expansion of its Mt Weld mine and concentration plant, including new crushing, grinding, flotation, apatite leach, dewatering, and drying facilities. The expansion aims to increase production capacity for rare earths, with construction expected to commence in early 2023 and full operation planned for 2024. As of October 2024, the new concentrate dewatering circuit transitioned to operations. A new hybrid power station (solar, gas, future wind) has been constructed.

Processing
Ore mined from the Mt Weld deposit is processed on-site at a concentration plant. The process involves crushing, grinding, flotation, and filtration to produce a mixed rare earths concentrate. This concentrate is then transported to Lynas' processing facilities in Kalgoorlie, Western Australia, for initial processing, or to Kuantan, Malaysia, for further separation and production of finished rare earth products.
Equipment
The mining fleet consists of 120-tonne to 200-tonne class hydraulic excavators and 80-tonne to 150-tonne class rear dump haul trucks, supported by standard ancillary machinery such as graders, dozers, and water carts. In March 2024, Carey Group Holdings was awarded a five-year contract for mining services, which includes mobilising a new mining fleet with a focus on technologies to improve efficiency. The processing plant utilises crushing and grinding infrastructure, flotation circuits, an apatite leach circuit, concentrate dewatering, drying, and load-out facilities.
Expansion
Lynas is undertaking a significant expansion project at Mt Weld, with a capital expenditure of approximately $500 million, to meet the growing global demand for rare earths. This expansion is designed to increase feedstock production capacity to support the production of 12,000 tonnes per annum of Neodymium and Praseodymium (NdPr) oxide finished product. The project includes upscaled processing equipment, efficiency improvements, and enhanced sustainability measures, such as a new hybrid gas and renewable energy power station. Stage 1 of the expansion, a new concentrate dewatering circuit, was operational in the latter half of 2024. The full expansion is expected to be completed in 2024. As part of the expansion, Lynas will transition from campaign-based mining to continuous mining operations.
