The proposed mine site is located in the Hamersley Ranges of the Central Pilbara region of Western Australia. The project involves the establishment of an open cut mine, associated mine infrastructure, and the construction of a 90 kilometre section of rail to link the mine with Hamersley Iron's existing rail network. The deposit to be mined is known as the Channel Iron Deposit, which is within the major aquifer in the area.

BHP Iron Ore has an existing operation along the Channel Iron Deposit, and has received approval from the Minister for the Environment to develop a second mine. This assessment has therefore, also considered the cumulative impact of this proposed third mine along the Channel Iron Deposit.
