Iron Ore

We continue to grow a portfolio of iron ore operations spanning the Yilgarn, Pilbara and Onslow regions.

As one of our company’s core commodities, iron ore remains critical to MinRes’ growth strategy.

Significant work is under way to transition our iron ore operations from short-life, high-cost mines to lower-cost, long-life projects.

Onslow hub

Our transformational Onslow Iron project is one of the largest iron ore projects under development in Australia, set to unlock billions of tonnes of stranded deposits in the west Pilbara region.

Yilgarn hub

Located in the Goldfields region, our Yilgarn hub includes the Koolyanobbing, Parker Range, Carina, Jackson, Windarling and Deception mine sites.

Pilbara hub

Our Pilbara hub includes the Wonmunna and Iron Valley mine sites in the Pilbara region.

Looking ahead

Future projects

Several future projects are planned to support MinRes' long-term iron ore activities.

Lamb Creek

Lamb Creek is a MinRes-owned iron ore deposit and exploration project, located 50 kilometres west of Iron Valley.

Production from Lamb Creek is planned to be incorporated into the Pilbara hub iron ore blend.

Primary approvals are expected in H1 FY25, with production forecast to commence in FY26.

South West Creek

MinRes has entered into a Port and Rail agreement with Hancock Prospecting (Hancock) and Roy Hill to jointly investigate and develop a new iron ore export facility at Port of Port Hedland.

Roy Hill would provide services to both MinRes and Hancock for the development and operation of the project, including rail haulage and port services.

The South West Creek project could see us shipping an additional 20 million tonnes of iron ore per annum.

The project remains subject to further approvals and agreements, and a positive final investment.


The Marillana Project is a 50:50 joint venture between MinRes and Brockman Mining Limited. Marillana is located approximately 100km north-west of Newman in the Pilbara.

The project contains total Mineral Resources of 1,404.4 million tonnes of hematite detrital (DID) and 101.9 million tonnes of channel iron deposit (CID) mineralisation. Metallurgical testwork and engineering studies have demonstrated that the detrital resources can be beneficiated from an average in-situ grade of 42.2% Fe to produce an iron ore fines product of over 60% Fe.

The Marillana project has the potential to provide a long-life supply of iron ore for MinRes’ Pilbara Hub.
