In its latest update, Fortescue has laid out what’s next for Iron Bridge in FY25—emphasising stronger plant performance, gradual scaling, and future-ready operations in Western Australia.
The update comes amid increased focus on Western Australia iron ore projects as global demand for premium magnetite concentrate rises. With a nameplate capacity of 22 million tonnes per annum (Mtpa), Iron Bridge stands as one of the company’s most advanced assets—and a cornerstone of its magnetite ambitions.

FY25 Outlook: Steady Ramping Toward Full Capacity
The Fortescue Iron Bridge FY25 guidance confirms a clear path toward operational stability, with expected magnetite output between 7 and 9 million tonnes. While still below full capacity, the projection reflects a cautious, data-driven ramp-up phase.
Chief Executive Dino Otranto highlighted operational improvements at the site’s dry processing plant, including the performance of the air classification circuit, which plays a critical role in removing contaminants and boosting concentrate purity.
“Iron Bridge is progressing well through ramp-up, with key elements of the plant now operating consistently,” said Otranto.
This guidance follows a series of upgrades and engineering reviews at the dry plant, aimed at ensuring process efficiency ahead of scaling up to the 22Mtpa design target.
Production Efficiency and Plant Review Drive Performance
Recent developments at Iron Bridge have placed emphasis on refining the project’s technical foundation—particularly in its air classification and dry screening circuits. These components are essential to meeting the high-grade specs Fortescue promises to steelmakers seeking cleaner, lower-emission input materials.
The dry plant review, completed earlier this year, has already informed equipment reconfigurations and system refinements. As a result, Fortescue is reporting stronger product consistency and a more predictable throughput profile.

FY25 Shipment Forecast and Market Context
Looking past Iron Bridge, Fortescue is projecting strong shipment volumes across its broader operations for FY25.The company expects total iron ore shipments across its portfolio to range between 192 and 197 million tonnes, including contribution from Iron Bridge’s ramp-up volumes.
This comes as the global iron ore market shows mixed signals—strong demand from India and Southeast Asia contrasts with softer-than-expected Chinese consumption in early FY25.
Still, Fortescue’s premium magnetite concentrate is well-positioned to benefit from environmental policies and steel decarbonisation goals, particularly in jurisdictions where lower-impurity feedstock is favoured.
Iron Bridge’s Long-Term Role in FY26–FY28 Forecast
Looking beyond FY25, Fortescue has placed the Iron Bridge operation at the centre of its mid-term production and sustainability goals. The site is expected to reach its full nameplate capacity of 22Mtpa by FY26, with FY27 and FY28 potentially bringing further optimisation and cost improvements.
The company continues to target emissions reduction across its value chain, and Iron Bridge’s premium magnetite is a key lever. Higher-grade magnetite not only boosts steel mill productivity but also reduces carbon intensity—an increasingly valuable trait in a climate-aware market.

A Strategic Project for Fortescue’s Evolving Identity
As Fortescue transitions from a pure-play iron ore exporter into a vertically integrated resources and clean energy player, Iron Bridge represents more than just a mine—it’s a flagship of technical ambition.
The site combines complex metallurgy, remote operations, and global-grade concentrate in a single operation—an example of how Australian miners are moving beyond volume and into value.
Conclusion: Fortescue Iron Bridge FY25 Guidance Reinforces Long-Term Strategy
The newly released Fortescue Iron Bridge FY25 guidance is a strong signal to markets that the company’s magnetite ambitions are on track. Iron Bridge is steadily stepping into a lead role within Fortescue’s portfolio, driven by ongoing plant upgrades, rising output targets, and market appetite for high-grade magnetite.
For stakeholders watching the evolution of Western Australia’s iron ore sector, Iron Bridge serves as a case study in patient capital, technical problem-solving, and the growing importance of premium-grade production in a carbon-conscious global market.
