The Group operates predominantly in only one geographic segment (Australia). During the year, the following segments were in operation: the Nickel Business, Lithium Business, and Growth, which comprises Regional Exploration Activities and Project Evaluation. The Tropicana Operation was sold effective 31 May 2021. The Nickel Business comprises the Nova Operation and the Forrestania Operation, both underground mining and processing operations, and the Cosmos Project, which is an underground development project. The Forrestania Operation and Cosmos Project were acquired during the year as part of the Group's transaction to acquire Western Areas Limited, which completed on 20 June 2022. The Nova Operation comprises the Nova underground nickel mine and processing operation which produces nickel and copper concentrates. Revenue is derived primarily from the sale of these concentrates containing nickel, copper and cobalt to multiple customers. The General Manager of the Nova Operation is responsible for the budgets and expenditure of the Operation. The Forrestania Operation comprises the Flying Fox and Spotted Quoll underground mines, and the Cosmic Boy processing facility. Nickel concentrate is produced, and revenue is derived primarily from the sale of these concentrates containing nickel to multiple customers. The General Manager of the Forrestania Operation is responsible for the budgets and expenditure of the Operation. The Cosmos Project comprises the development of the Odysseus underground mine focused on the production of nickel concentrate. The General Manager of the Cosmos Project is responsible for the budgets and expenditure of the Project. The Lithium Business represents the Group's 49% share in the Lithium joint venture, Tianqi Lithium Energy Australia Pty Ltd (TLEA), with Tianqi Lithium Corporation. The existing assets of TLEA include the Greenbushes Lithium Mine and the Kwinana Lithium Hydroxide refinery located in Western Australia, to which the Group holds an indirect interest of 24.99% and 49%, respectively. The transaction completed on 30 June 2021 and the investment is equity accounted by the Group. The Tropicana Operation represented the Group's 30% joint venture interest in the Tropicana Gold Mine.

The Group’s General Manager - Exploration is responsible for budgets and expenditure relating to the Group’s regional exploration, scoping studies and feasibility studies, and the Head of Corporate Development is responsible for budgets and expenditure relating to new business development. The Growth division does not normally derive any income. Should a project generated by the Growth division commence generating income or lead to the construction or acquisition of a mining operation, that operation would then be disaggregated from the Growth division and become reportable in a separate segment.
