Mont Royal Eyes Separated Rare Earth Oxides Through Alta Separation Partnership
Key Takeaways
- Mont Royal Resources has signed a Joint Study Agreement with Alta Resource Technologies to evaluate Mont Royal Ashram REO separation — a downstream move from mixed rare earth carbonate into higher-value separated oxides including NdPr, dysprosium and terbium.
- Alta's engineered protein-based separation technology has already demonstrated greater than 99.5% purity and greater than 90% yield on magnet rare earth oxides, though those results were achieved on other feedstocks — the JSA will test whether Ashram-derived MREC can match that performance.
- The Ashram 2026 PEA (±50% accuracy) underpins a 30-year mine life, 17,466 tonnes of average annual saleable REO, a C$2.03 billion post-tax NPV and 22% IRR — figures that assume MREC production and could improve materially if separated oxide production proves feasible.
- Alta's credibility extends beyond the lab: the company has a partnering agreement with Korea Zinc, the world's largest non-ferrous metals smelter, targeting commercial production of high-purity NdPr, dysprosium and terbium from recycled magnets by 2027.
- The JSA is an initial step only — no joint venture, refining facility or downstream production has been confirmed, and all outcomes remain conditional on study results.
Mont Royal targets high-purity rare earth oxides through Alta separation partnership
Mont Royal Resources (ASX: MRZ, TSXV: MRZL) has signed a Joint Study Agreement with Alta Resource Technologies to evaluate producing separated, high-purity rare earth oxides from mixed rare earth carbonate feedstock derived from its Ashram Rare Earth & Fluorspar Project in Québec. The announcement, dated 31 August 2026, signals a potential move further downstream into the rare earth value chain.
The study assesses whether Mont Royal can capture more value from its resource by producing separated oxides rather than stopping at mixed carbonate, a higher-margin product targeting North American supply chains for permanent magnets, defence and advanced technologies. The agreement is intended as an initial step toward a potential joint venture, though no commercial partnership has been confirmed.
What the Joint Study Agreement covers
The scope of the JSA includes:
- Evaluating the application of Alta’s engineered protein-based rare earth separation technology to mixed rare earth carbonate (MREC) feedstock from Ashram.
- Assessing a pathway to produce separated, high-purity rare earth oxides from Ashram-derived MREC.
- Assessing the potential for a future commercial refining facility and longer-term partnership.
- Collaboratively assessing how to bridge Mont Royal’s hydrometallurgical process with Alta’s separation process.
The JSA is intended as an initial step toward a potential joint venture. No joint venture, refining facility or downstream production has been confirmed — all outcomes are conditional on study results.
Nicholas Holthouse, Managing Director
“Our current focus on producing a mixed rare earth carbonate remains a practical and lower-risk development strategy for the Ashram Project. However, the ability to take that product further downstream and potentially produce separated, high-purity rare earth oxides in North America represents a significant opportunity for Mont Royal. Working with Alta brings an innovative separation technology and specialist expertise which could provide a pathway for us to achieve that without Mont Royal having to develop the capability independently. Importantly, this also aligns with the growing strategic focus in Canada and the United States on establishing secure Western supply chains for rare earth elements required for permanent magnets, defence and advanced technologies.”

Understanding Ashram and why separation matters
The rare earth value chain flows from ore to mixed rare earth carbonate (MREC) to separated individual high-purity oxides. Mont Royal’s current focus is MREC. This JSA explores the next downstream step.
Separated oxides matter because individual rare earth elements — neodymium-praseodymium (NdPr), dysprosium (Dy), terbium (Tb) — are the actual inputs for permanent magnets used in electric vehicles, wind turbines, defence systems and advanced technologies. Higher purity means higher value. Separating the elements yourself rather than selling a mixed product means capturing more of the resource’s value.
Alta’s approach uses engineered proteins that selectively bind and separate target metal ions. This is a modular separation method that may support cleaner processing and potentially lower capital intensity than conventional chemical separation routes.
Ashram’s rare earth oxide profile:
- One of the largest undeveloped rare earth projects in North America; monazite-dominant carbonatite-hosted; located in Nunavik, Québec.
- ~4,035 tonnes per annum of NdPr oxide expected (per 2026 PEA).
- Rich in heavy rare earths: dysprosium (Dy), terbium (Tb), samarium (Sm), europium (Eu), gadolinium (Gd), yttrium (Y).
The heavy rare earth content is strategically significant. Dysprosium and terbium are critical for high-performance permanent magnets. These elements are scarce and expensive. Ashram’s heavy rare earth endowment means the separation upside extends beyond NdPr.
Alta’s proven technology and strategic credibility
Alta Resource Technologies describes itself as a pioneer in “precision mining” — an approach emphasising accuracy, lower environmental impact and full mineral valorisation. The company’s processing platform uses engineered proteins to separate rare earth elements and other strategic materials with high selectivity. By tailoring proteins to bind selectively to individual elements, Alta’s process is built to recover the full value of a resource with a minimal footprint.
Alta’s technology has previously demonstrated intralanthanide separation of magnet rare earth oxides (NdPr, Dy, Tb) and SEG+ (Sm, Eu, Gd, Y) at greater than 99.5% purity and greater than 90% yield. The JSA will determine whether comparable results can be achieved with Ashram-derived MREC. Those results were achieved on other feedstocks, not Ashram’s. The study tests whether Ashram’s MREC can deliver the same performance.
Alta’s recent strategic partnerships add credibility. The company has entered a partnering agreement with Korea Zinc, the world’s largest non-ferrous metals smelter, to establish a US-based rare earth recycling joint venture, targeting commercial production of high-purity NdPr, dysprosium and terbium from end-of-life magnets by 2027. That tells you Alta’s technology has attracted industrial-scale capital and is being deployed commercially, not just tested in a lab.

“Mont Royal has a world-class resource and the expertise to extract it. Alta has a separation technology purpose-built for valorising complex mixtures of rare earth elements. Together, we will provide a durable North American rare earth supply chain necessary for Western manufacturers to produce permanent magnets and advanced technologies.”

The investment case and what comes next
This positions Mont Royal to potentially capture more value downstream without funding the separation capability alone. The strategic alignment is clear — Canada and the United States are actively pushing to establish secure Western supply chains for rare earth elements required for permanent magnets, defence and advanced technologies. The Canada-U.S. Joint Action Plan on Critical Minerals explicitly targets rare earth supply chain resilience. Processing Ashram MREC into separated high-purity oxides in North America would directly serve that objective.
The 2026 Preliminary Economic Assessment for Ashram provides the baseline economics. The PEA is preliminary and carries ±50% accuracy. It was first reported on 9 June 2026. The table below summarises the key metrics.
| Ashram 2026 PEA metric | Figure |
|---|---|
| Mine life | 30 years |
| Average annual saleable REO | 17,466 tonnes |
| Post-tax NPV | C$2.03 billion |
| Post-tax IRR | 22% |
| Payback period | 3.9 years |
Those figures assume MREC production. If the study concludes that separated oxide production is technically feasible and economically superior, the project economics could improve materially. Higher-purity products command higher prices. The separation step adds cost, but it also adds margin if Alta’s technology delivers the claimed efficiency and purity at scale.
Next steps are conditional. The study will assess technical feasibility. If results are positive, the parties may assess a potential commercial refining facility and potential joint venture. No timelines have been confirmed beyond the study phase itself.
What this tells you is that Mont Royal is positioning to move beyond mixed carbonate — a commodity product — into separated oxides, which are higher-value, strategically critical inputs. The partnership with Alta provides access to proven separation technology without requiring Mont Royal to develop that capability independently. The strategic context — Western governments actively funding rare earth supply chain development — creates a tailwind. If the study delivers, Mont Royal would be positioned as a vertically integrated North American rare earth producer at a time when geopolitical risk is driving premium valuations for secure, Western-domiciled supply.
