Processing
The operation uses a Greentech plant with a three-stage crushing circuit and a dense media separation plant. The process uses 100% renewable energy, 100% recycled water, no hazardous chemicals, and features dry-stacked tailings.
Expansion
The company is constructing a second Greentech plant (Phase 2) to add 250,000 tonnes of annual capacity, bringing total expected production to 520,000 tonnes per year. Earthworks for the expansion began in early 2024. Commissioning of the second plant is expected to begin in the fourth quarter of 2025, with completion by the end of 2026. A January 2024 update increased the audited mineral resource by 27% to 109 million tonnes, supporting a mine life of over 20 years. Proven and Probable reserves increased by 40% to 77 million tonnes at 1.4% lithium oxide.

Overview
Greenbushes is an open-pit mine located in Western Australia, producing lithium, tantalum, and tin. It is operated by Talison Lithium Australia Pty Ltd. Talison Lithium is owned by a joint venture between Tianqi Lithium Energy Australia Pty Ltd (TLEA) (51%) and Albemarle Corporation (49%). IGO Limited has a 49% interest in TLEA, giving it a 24.99% indirect interest in Greenbushes, with Tianqi Lithium Corporation holding the remaining 51% of TLEA.
Production
Production overview - 2025: lithium 1350000 t; 2024: lithium 1480000 t.
Processing
The Greenbushes operation has four processing plants: one for technical grade lithium concentrate, two for chemical grade lithium concentrate, and a tailings retreatment plant. A third Chemical Grade Plant (CGP3) commenced commissioning with its first ore feed on 18 December 2025. The CGP3 project's total cost is estimated at approximately A$880M. CGP3 adds about 500,000 tonnes per year of spodumene concentrate capacity, increasing the total site capacity to around 2.1 million tonnes per year. CGP3 is expected to reach nameplate capacity in 2026. Further plant debottlenecking is planned to lift combined production during 2027, with total ore processed expected to increase to approximately 7 million tonnes per year by 2028.
Expansion
A significant expansion is underway to increase the production of lithium mineral concentrate. The Western Australian Environmental Protection Authority (EPA) has approved amendments to the development envelope, increasing it from 2,207 hectares to 2,791 hectares. The expansion includes the construction of new waste rock landforms, the expansion of the Salt Water Gully Dam, and new water management infrastructure. A review is also underway to assess options for underground mining, with a new underground Mineral Resource Estimate of 132 million tonnes grading 1.5% Li₂O defined below the current open pit.

Overview
The Mt Ida Project is described as "shovel-ready" and is currently under development. As of November 2023, the project has received all statutory approvals for the commencement of open pit mining operations from the Western Australian Department of Mines, Industry, Regulation and Safety (DMIRS), including an approved Mining Proposal and Mine Closure Plan. The project is fully permitted for both open pit and underground mining. Feasibility studies for a lithium concentrate project are underway.
Production
Production overview - 2025: lithium 14.8 Mt, rhodium 14.8 Mt, tantalum 14.8 Mt; 2024: gold 752000 oz.
Processing
The proposed processing method is a whole-of-ore flotation (WOF) flowsheet. This process is designed to produce tantalite, mica, and spodumene concentrates. Test work has confirmed that rubidium can be readily extracted as a by-product within the mica pre-float stage, with recoveries averaging around 90%. Downstream processing and vertical integration studies are in progress.
Equipment
multiple reverse circulation (RC) and diamond drill rigs
Expansion
Significant potential for further resource growth, with ongoing drilling programs aimed at expanding the current mineral resources. A new LCT (Lithium-Caesium-Tantalum) pegmatite discovery has been made in the Sister Sam footwall, indicating exploration upside.

The mine and concentrator are designed to produce 380,000 tonnes of spodumene concentrate per year. This concentrate will be processed at the Kwinana refinery to produce approximately 50,000 tonnes of battery-quality lithium hydroxide annually. First ore was mined in December 2022, and the concentrator was commissioned in the second half of 2023. The first production of lithium hydroxide is expected in early 2025.
Processing
The project is an integrated operation that includes a mine and concentrator at Mt Holland and a lithium hydroxide refinery in Kwinana. The concentrator processes spodumene ore to produce spodumene concentrate. The processing plant includes primary and secondary crushing, a high-pressure grinding roller (HPGR), dense media separation (DMS), grinding and classification, magnetic separation, and froth flotation. The concentrator is designed to process approximately 2 million tonnes of ore per year.
Equipment
Mining operations are conducted by contractors. Thiess delivers drill and blast services, mining of overburden and ore, and equipment maintenance. Iron Mine Contracting provides drill, blast, load and haul, and run-of-mine management services. The operation will be serviced by contractor-owned and operated drill and blast, as well as load and haul equipment, including excavators and haul trucks.
Expansion
A feasibility study is underway to evaluate doubling the production capacity of the mine and concentrator. Covalent is seeking approval to expand the processing capacity from 2 to 4 million tonnes per annum (Mtpa).

The project is considered a potential open-pit operation, primarily targeting lithium and tantalum from LCT pegmatite dykes, and is also prospective for gold.
Equipment
Reverse Circulation and Diamond drilling program
Expansion
Significant expansion is underway, with further RC drilling planned for the first quarter of 2026 to step out and infill the discovery area in preparation for a maiden Mineral Resource estimate. Diamond drilling is also planned to expand the scale of the discovery at depth and to facilitate metallurgical test work. The company is also progressing with environmental studies and plans to lodge a mining lease application. The Bolt Cutter project is seen as a potential satellite operation to the flagship Tabba Tabba project, with the potential to establish a major new lithium mining and processing operation in the Pilbara.
