Brockman 2 is an iron ore mine, consisting of several pits immediately south of the Nammuldi iron ore mine, at the northern base of Mount Brockman. The mine is 55 kilometres north-west of Tom Price.

The mine started with the extraction of detrital ore from 1992 to 1998. After this Brockman bedded deposits were mined, capable of producing 8.7 Mtpa. Former P4, P4 Extension, Valley and Pit 6 were amalgamated into the B52 pit. To the west is Pit 1, 2 and 3, while to the north-east is the small pit 5, and south pit 7.

The ore is presently being obtained from the Dales Gorge Member banded iron formation. In 2011, Proven and Probable reserves were 35 Mt at 62.3% Fe. Measured, Indicated and Inferred resources were 20 Mt at 62.3% Fe, all as part of the Brockman Iron Formation. As detrital ore, the Indicated and Inferred resource is 26 Mt at 60.2% Fe.
