In the dusty expanse north of Leinster lies one of Western Australia’s most ambitious nickel assets, the IGO Cosmos Nickel Project. This operation sits quietly for now, in care and maintenance, waiting for the next chapter of Australia’s clean energy revolution. Cosmos is not just another mine paused by the market; it is a fully developed underground system that will eventually return to production with more technology, more automation, and more opportunity than ever before.
For anyone preparing a career in mining, understanding Cosmos is about looking forward. It represents where the industry is heading: high-grade nickel, fully electrified operations, and careers that combine physical skill with modern digital systems.
2. About IGO Limited and Its Vision
IGO Limited has built its reputation as a leader in Australia’s clean energy metals sector. The company operates across multiple commodities that power the modern world, including lithium, copper, cobalt, and nickel. With assets such as the Nova Operation in the Fraser Range, the Greenbushes Lithium Mine, and partnerships in the Kwinana Refinery, IGO is one of the few companies connecting underground mining with battery-grade processing.
Cosmos is central to that strategy. Purchased from Western Areas in 2022, the project includes extensive underground development, a modern concentrator, and a camp ready to support hundreds of workers. It is positioned to become one of Western Australia’s most advanced underground operations once nickel prices rebound.
3. Location and Access
Cosmos sits about thirty kilometres north of Leinster in the northern Goldfields, surrounded by other major operations including BHP Nickel West and Northern Star’s gold mines. Most employees will travel on FIFO flights from Perth to Leinster Airport, followed by a short site transfer.
Because of its location, Cosmos offers a true FIFO experience: remote work, structured routines, long shifts, and strong team culture. The camp is designed to create a comfortable balance between demanding underground work and quality downtime.
4. Operations and Development
The project’s key orebody, Odysseus, lies deep beneath the surface, containing high-grade nickel sulphides that feed the global demand for electric vehicles and renewable energy storage.
The Underground System
Mining at Odysseus is planned through long-hole open stoping with paste backfill. The underground network is already fully developed, giving Cosmos a fast track to production once the restart is confirmed.
Surface Infrastructure
Cosmos has a processing plant capable of treating around 750 thousand tonnes of ore each year. It includes crushing, grinding, and flotation circuits designed for premium nickel concentrate. Supporting facilities include a paste fill plant, workshops, power generation, water supply, and modern worker accommodation.
Technology Focus
IGO has been gradually transforming Cosmos into a next-generation site. The company has tested electric underground vehicles, introduced advanced fatigue monitoring, and designed remote operation capability for future control systems. Employees joining the restart will work in one of the most technologically forward underground mines in Australia.
