Iluka Resources Locks in 18-Year Rare Earths Supply for Eneabba

Iluka Resources locked in 146,000 tonnes of rare earths concentrate from VHM Limited’s Goschen project on 7 July 2026, securing an 18-year supply pipeline for a refinery that is already more than halfway built. The binding offtake agreement, paired with a A$40 million financing commitment, arrives as Western governments accelerate efforts to reduce dependence on Chinese rare earths processing. With Eneabba’s commissioning targeted for mid-2027, Australia’s first end-to-end rare earths refinery is no longer a concept; the feedstock question that once sat at the centre of its risk profile now has a structured answer. What follows covers the precise terms of the deal, how the financing is designed to pull Goschen toward construction, the refinery’s current build status, and what the arrangement signals for Australian critical minerals investors.

The deal in detail: what Iluka and VHM have actually agreed to

The agreement is binding, not a memorandum of understanding or a heads-of-agreement framework. Its specificity sets it apart from the letters of intent that have characterised much of Australia’s critical minerals deal flow in recent years.

The core terms break down as follows:

• Volume: 146,000 tonnes of rare earths concentrate over 18 years, containing approximately 86,000 tonnes of total rare earth oxides (REO)
• Annual throughput: Approximately 8,320 tonnes of concentrate per year, yielding roughly 4,900 tonnes of REO per year
• Product: Rare earths concentrate from Goschen, delivered to Iluka’s Eneabba refinery in Western Australia
• Pricing mechanism: Goschen concentrate pricing is indexed to the basket price Iluka realises from selling separated rare earth oxides out of Eneabba
• Right of first refusal: Iluka holds first refusal over any additional VHM rare earths production from Goschen, plus output from VHM’s earlier-stage Cannie and Nowie projects

The pricing linkage is the structural detail that matters most for investors. VHM’s revenue rises and falls with the prices Iluka achieves for its separated oxides, creating genuine commercial alignment between the upstream miner and the downstream refiner.

Iluka managing director Tom O’Leary described the arrangement as a further step in building out Iluka’s rare earths business and advancing Australia’s broader rare earths sector, adding that the company looks forward to VHM bringing Goschen into production.

How Iluka’s A$40 million is structured to get Goschen built

The financing is not a passive balance-sheet investment. It is a two-tranche convertible note designed to pull Goschen across the Final Investment Decision (FID) threshold by giving the project a credible anchor in its funding stack at the moment it matters most.

The split is deliberate. For VHM shareholders, a 100% offtake agreement paired with committed convertible note funding from the downstream customer is designed to be bankable for project financiers, strengthening Goschen’s case with external lenders and equity partners. For Iluka, the structure limits exposure: the full A$40 million is not deployed unless Goschen’s construction funding is substantially assembled.

Government backing adds a second layer of validation

Both the Australian federal government and the US government have issued letters of funding interest for the Goschen project. This is not commercial financing, but it signals independent validation of the project’s relevance to Western-aligned critical minerals supply chains, beyond the Iluka commercial relationship. Two governments from separate continents flagging the same pre-production rare earths project adds weight to Goschen’s funding narrative at a critical stage.

What the Goschen project brings to Australia’s rare earths mix

Goschen sits in Victoria’s Loddon Mallee Region, fully permitted with environmental approvals in place as of July 2026. The project is planned at approximately 5 Mtpa mining rate over roughly 20 years, a scale that underpins the 18-year concentrate supply commitment to Eneabba.

What distinguishes Goschen from a generic rare earths deposit is its heavy rare earth profile. Rare earth elements fall into two broad categories, and the distinction carries real pricing and supply-chain consequences:

• Heavy rare earths (dysprosium, terbium, yttrium): Critical inputs for high-performance permanent magnets used in electric vehicle motors and defence applications. These elements are among the most supply-constrained in the global energy transition and typically command premium pricing.
• Light rare earths (neodymium-praseodymium, or NdPr): Essential for permanent magnets but more widely produced globally, with Chinese processors dominating supply.

Goschen’s concentrate is expected to deliver both categories to Eneabba. The heavy rare earth content is not incidental. Dysprosium and terbium sourced from a Victorian mine and processed at an Australian refinery would materially reduce reliance on Chinese processing of these elements, which is precisely the supply-chain gap Western governments are attempting to close.

The IEA Global Critical Minerals Outlook 2026 identifies dysprosium and terbium as facing acute supply concentration risks, noting significant price divergence in European markets as export controls from dominant producers expose the cost of securing heavy rare earths outside established Chinese processing networks.

Iluka’s own western Victoria play adds upstream optionality

Iluka is advancing its own Wimmera development project in the same regional province, currently progressing through a definitive feasibility study. This positions Iluka as both an upstream participant and a downstream refiner within western Victoria’s rare earths-productive corridor, a dual role that few Australian miners have assembled.

Eneabba at the halfway point: how the refinery build has progressed

The upstream logic of the VHM deal only matters if the downstream facility exists. As of July 2026, it increasingly does.

Iluka’s Eneabba Rare Earths Refinery is more than 50% complete and is targeting commissioning in mid-2027, positioning it as Australia’s first end-to-end integrated rare earths refinery capable of producing separated light and heavy rare earth oxides in a single integrated process.

Passing the 50% construction mark shifts Eneabba’s risk profile. Cancellation or indefinite delay is no longer the base-case scenario; the question has moved from whether the refinery will be built to whether it will commission on schedule.

Iluka intends to operate Eneabba on a dual-feed model, blending internal Iluka mineral resources with third-party feedstocks such as VHM’s Goschen concentrate. The overall output mix is expected to be optimised against circuit capacity constraints.

The refinery’s commercial milestones already achieved reinforce that this is an operating business in formation, not a concept study:

• Final construction contract awarded
• First offtake agreement for separated rare earth oxides already signed
• VHM feedstock deal now secured under binding 18-year terms

If the mid-2027 commissioning target holds, Australia enters the global rare earths oxide supply picture before the decade’s end.

The bigger picture: what this partnership reveals about Australia’s rare earths ambition

Strip back the transaction details and the Iluka-VHM arrangement is a working model of upstream-downstream integration: a Victorian miner supplying a Western Australian refinery under a long-term contract with shared pricing exposure. That model is precisely what Western governments, and the critical minerals strategies they are funding, have been calling for.

Government letters of funding interest from both Australia and the United States for Goschen underline how seriously both countries treat this category of project. The interest is not speculative; it reflects a policy consensus that rare earths processing capacity outside China is a priority for energy transition and defence supply chains.

Australia’s Critical Minerals Strategy 2023-2030 explicitly targets the development of domestic processing capacity and international supply chain partnerships, framing projects like Eneabba not as isolated commercial ventures but as deliberate instruments of national industrial policy.

For ASX investors tracking critical minerals, the Iluka-VHM structure illustrates what a credible Australian rare earths play looks like at this stage of the cycle: binding contracts, phased financing, and a refinery that is physically being built.

The tension, though, sits in what must still fall into place:

• Goschen must reach FID and commence production
• Eneabba must complete construction and commission on schedule in mid-2027
• The pricing environment for separated rare earth oxides must support the economics both companies are building toward

The architecture is assembled. Execution remains the open variable.

What Australia’s first rare earths supply chain closing looks like from here

The deal delivers three distinct layers of value: feedstock security for Eneabba over nearly two decades, financial support for Goschen’s pathway to FID, and embedded optionality over VHM’s broader project portfolio through the right of first refusal covering Goschen upside, Cannie, and Nowie.

Eneabba’s mid-2027 commissioning target is the near-term proof point. If met, it confirms that Australia can build, staff, and operate a fully integrated rare earths refinery, a capability that did not exist domestically before this project.

The milestones investors should watch from here:

• Goschen FID date: Triggers the A$30 million second tranche and confirms the supply chain’s operational timeline
• Eneabba commissioning: Confirms refinery readiness to receive and process feedstock
• Further VHM feedstock announcements: Any exercise of Iluka’s right of first refusal over Cannie or Nowie production would expand the supply chain’s scale

This is not a letter of intent. It is a binding 18-year, 146,000-tonne supply agreement paired with A$40 million in structured finance, a construction site past its halfway point, and government interest from two continents. The next material catalyst is Goschen’s FID.
