The Brockman 2 Detrital Iron Ore Mine (B2 Project) commenced mining operations in 1992 in the central Pilbara region of Western Australia. It is located in the Brockman Syncline area, approximately 55 kilometres (km) northwest of Tom Price. Ore from the mine is currently exported through Dampier and Cape Lambert ports.

This proposal is for the Phase 2B development of the B2 Project and involves further development of parts of the existing Pit 4 Extension, Lower Pit 4, Valley Pit and Pit 6 to an approximate depth of 530 mRL to form an amalgamated pit known as the BS2 Pit.
