Iluka rare earths offtake: project finance and supply lessons for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Iluka Resources has signed its first rare earths offtake, a binding multi-year take-or-pay contract to supply neodymium, praseodymium, dysprosium and terbium magnet rare earth oxides from 2028 to a globally recognised automotive manufacturer. The initial four-year deal covers about 10 per cent of planned output from Iluka’s Eneabba rare earths refinery in Western Australia, currently under development with federal support. For miners and processors, the agreement signals growing OEM willingness to lock in long-term supply for magnet-grade REO, underpinning project financing and downstream processing investment.
Technical Brief
- Take-or-pay structure shifts volume risk to the automotive buyer, supporting Iluka’s refinery revenue certainty.
- Contracted basket focuses on high-value magnet REOs, excluding cerium and lanthanum by design.
- Offtake volume certainty will be central to debt financing and credit support negotiations for the refinery.
- Locked-in downstream demand incentivises Iluka to optimise flowsheet recoveries specifically for Nd, Pr, Dy, Tb.
Our Take
Iluka Resources appears repeatedly in our rare earths coverage alongside items such as Energy Fuels’ proposed acquisition of Australian Strategic Materials, signalling that Australian rare earths assets are becoming more tightly contested by downstream and North American players seeking secure neodymium–praseodymium and heavy rare earth supply.
With the offtake only beginning in 2028 and covering around 10 per cent of Iluka’s magnet rare earth oxides output, the structure leaves room for additional contracts or strategic customers, which is likely to be important as more Australian rare earths projects in the federal Critical Minerals Prospectus move towards midstream processing decisions.
The inclusion of dysprosium and terbium in this offtake aligns with other heavy rare earth element stories in our database, such as Victory Metals’ North Stanmore project, and suggests that Australian producers are positioning to supply not just volume NdPr but also the smaller heavy rare earth streams needed for high-temperature magnets in defence and EV drivetrains.
