The Cosmos Project, wholly owned by IGO Limited, is located 30 kilometres north of Leinster in Western Australia. Following a review that showed a reduced expected mine life, delays, and increased costs, coupled with a significant deterioration in commodity prices, IGO made the decision to transition the project into care and maintenance. This transition was completed in June 2024. The company intends to maintain the project's assets to preserve the option for a restart if market conditions improve. The primary focus of development before the suspension was the Odysseus underground mine. As of 30 June 2025, all previously reported JORC Code reportable Ore Reserve and Mineral Resource estimates for the Cosmos Project have been declassified.

The first saleable nickel sulphide concentrates were produced during the 2024 fiscal year. Nearly 295,000 tonnes of ore from the Odysseus mine were processed between 6 November 2023 and 22 May 2024, after which processing ceased.

The on-site concentrator was upgraded to a throughput capacity of 1.1 Mtpa, with commissioning commencing in October 2023. Wet commissioning of the plant was being finalised as part of the transition to care and maintenance.

The operation includes the Cosmic Boy processing facility. Following the acquisition by Medallion Metals, the plant and infrastructure will be used to process ore from Medallion's Ravensthorpe Gold Project. Medallion Metals will rename the project the Forrestania Gold Project and it will serve as the company's long-term gold processing and development hub.

IGO Limited completed the sale of the Forrestania Nickel Operation to Medallion Metals Limited on 2 March 2026. The transaction included the Cosmic Boy processing plant, infrastructure, inventories, and rehabilitation obligations, with no cash consideration. IGO will receive up to a 1.5% net smelter return royalty on future gold production from the tenements. Medallion Metals' acquisition is aimed at creating a new gold and copper producer by combining its Ravensthorpe Gold Project resources with the Forrestania infrastructure.

The transition to care and maintenance was expected to result in redundancies, though IGO planned to offer some redeployment opportunities.

The Cosmos Project is 100% owned by IGO Limited and is located 30 kilometres north of Leinster in Western Australia. The project includes the development of the Odysseus underground mine. In June 2024, the project was formally transitioned into a state of care and maintenance. This decision was made following a review that identified a shorter expected mine life, delays in reaching full production capacity, and increased operating and capital costs, which was exacerbated by a significant decline in nickel prices. IGO intends to maintain the assets to preserve the option of restarting the project if market conditions improve. As of March 2026, IGO is exploring options to rationalise the Cosmos site and its infrastructure, noting the region is prospective for gold and other minerals, and that the company retains plant and equipment on site that could support mining and processing of such commodities.

Operations ceased on 22 May 2024. The processing of existing ore on the run-of-mine pad was completed as part of the transition to care and maintenance.

The project includes a refurbished concentrator with a new SAG mill, designed with a capacity of 1.1 million tonnes per annum. The processing plant was wet-commissioned prior to the transition to care and maintenance.
