Iron Ore – MAC Royalty’s cornerstone asset

Mining Area C is located approximately 90km north west of Newman Township in the Pilbara region of Western Australia, one of the premier iron ore provinces in the world.

Operated by BHP, Mining Area C will form the largest operating iron ore hub in the world, producing 145 million tonnes of iron ore each year when the recently completed South Flank expansion reaches full production.

Royalty Agreement

Deterra’s royalty agreement with BHP and its partners Itochu and Mitsui (the “MAC”) provides for a revenue-based royalty and production capacity payments consisting of:

  • ongoing quarterly royalty payments of 1.232 per cent of Australian denominated revenue from the MAC Royalty Area; and
  • a series of one-off payments of AUD$1 million per million dry tonne increase in the annual production level from the MAC Royalty Area during any 12 month period ending 30 June above the previous highest annual production level.


Demonstrated annual capacity as at 30 June 2023 is set at 118Mdmt

Production for FY23

Mining Area C experienced significant organic growth with an annual production of 126 million wet metric tonnes, up 14 per cent on FY22.

North and South Flanks

Mining Area C has two major operations:

  1. The North Flank, which has been operational since 2003 with a history of consistent and growing iron ore production and current capacity of 65 million wet tonnes per year (mwtpa); and
  2. The South Flank, Australia’s largest new iron ore mine in over 50 years, which achieved first production in May 2021 folllowing a USD3.6 billion development project. South Flank is a sustaining mine which will replace declining production from mines outside the MAC Royalty Area and has an announced capacity of 80 million mwtpa.


Current MAC operations are expected to continue until ~2050, with the potential for further extension.
