Overview
IGO Limited transitioned the Cosmos Project into care and maintenance in June 2024. This decision followed a comprehensive review that commenced in mid-2023, which highlighted a reduction in the expected mine life, delays in reaching full capacity, and increases in operating and capital costs, all exacerbated by a significant deterioration in nickel commodity prices. As a result of the review, IGO recorded a non-cash, pre-tax impairment expense against the Cosmos assets. The company is exploring options to rationalise the site and its infrastructure, noting the region is also prospective for gold and other minerals. While on care and maintenance, IGO is assessing the value of continuing select exploration programs to potentially increase the mineral resource.
Production
Production overview - 2024: nickel 1734 t.

Overview
The Greenbushes Lithium Mine is an operating open pit mine in Western Australia, producing lithium and tantalum. Operated by Talison Lithium Australia Pty Ltd, IGO Limited holds an effective indirect interest of 24.99%. The mine employs approximately 1,700 people. Processing utilizes gravity, heavy media, flotation, and magnetic processes across four plants, including the recently commissioned CGP3, which boosted total spodumene concentrate capacity to around 2.1 million tonnes per annum. An expansion to the east and south is proposed, with potential for an additional Chemical Grade Plant 4 (CGP4).
Production
Production overview - 2025: lithium 1350000 t; 2024: lithium 1420000 t.
Processing
The operation has four processing plants: three that produce chemical-grade lithium concentrates (CGP1, CGP2, and a Tailings Retreatment Plant) and one that produces technical-grade lithium concentrates. The ore is upgraded using gravity, heavy media, flotation, and magnetic processes. The third Chemical Grade Plant (CGP3) processed its first ore on 18 December 2025. CGP3 has a capacity of approximately 500,000 tonnes per annum of spodumene concentrate, which will increase the total site capacity to around 2.1 million tonnes per annum.
Equipment
Mining is a traditional drill and blast method. A contractor for crushing operations uses a D10 dozer, 980 loader, 36-tonne excavator, jaw crusher, impact crusher, and screener. Macmahon has a 7-year contract for load and haul services and crusher feed, which commenced on 1 July 2023.
Expansion
Talison Lithium is proposing an expansion of the mine to the east and south to increase the production of spodumene ore and lithium mineral concentrate. This involves the construction of new waste rock landforms, expansion of the Saltwater Gully Dam, and other supporting infrastructure. The proposal would increase the development envelope from 2,207 hectares to 2,826 hectares. The Western Australian Environmental Protection Authority (EPA) has approved amendments to the development envelope, increasing it to 2,791 hectares. A public review period for the expansion is expected to begin in February 2026, with a final EPA assessment report anticipated in December 2026. There are also development options for an additional Chemical Grade Plant 4 (CGP4).
