Iluka's Eneabba heavy rare earths refinery passes 65% construction
Heavy rare earth separation outside China barely exists. Eneabba is one of the few plants that could change that, and it is now past the halfway mark.
What happened
Iluka Resources has completed 65% of construction at its Eneabba rare earths refinery in Western Australia, with capital expenditure reaching A$1.237 billion, Australian Mining reported on 28 October, citing the company's September 2026 quarterly report. The capital estimate remains A$1.7–1.8 billion.
The refinery will produce separated magnet rare earth oxides, including neodymium, praseodymium, dysprosium and terbium. It is being built through a strategic partnership with the Australian Government and supported by a non-recourse loan under the Critical Minerals Facility run by Export Finance Australia. The Bull noted a broad rebound across Australian rare earth stocks on the update.
Our take
This is the kind of capacity that actually narrows the processing gap. Heavy rare earths such as dysprosium and terbium are where China's licensing has the most leverage, and Eneabba is one of very few projects outside China designed to separate them at scale.
Holding the capital estimate at 65% completion is the important detail; large refinery builds outside China have a history of overruns. The remaining risks are commissioning, feedstock quality and whether Iluka can sign offtakes that support its cost base against Chinese pricing.
Why it matters for AI infrastructure
Dysprosium and terbium let NdFeB magnets keep their strength at high temperatures, which matters in the motors behind data-centre cooling, power equipment and robotics. They are also the elements most exposed to China's April 2025 licensing regime.
An allied source of separated heavy oxides would give magnet makers in the US, Japan and Europe something they lack today: a supply they can qualify without depending on Beijing's licences.
What we're watching
- Any change to the A$1.7–1.8B capital estimate
- Commissioning timeline and first on-spec dysprosium and terbium oxide
- Feedstock deals, including the VHM supply agreement
- Offtakes with US, Japanese or European magnet makers
