Phase 2 at Nolans — The Most Undervalued Optionality in Rare Earths
When investors discuss Arafura Rare Earths, the conversation almost always centres on financing milestones, offtake agreements, or Phase 1 production volumes. What receives far less attention, yet will ultimately drive the most strategic value — is the embedded expansion optionality at the Nolans project.Background - Phase 1
Phase 1 production (~4,400 tpa NdPr oxide) positions Nolans as a meaningful ex-China supplier. But from a strategic supply-chain perspective, that volume alone doesn’t fundamentally shift global dynamics.Phase 2 (at around 11,000 tpa NdPr Oxide), however:
- Potentially massively increases oxide output.
- Leverages already-permitted infrastructure and process design.
- Benefits from operational learning curves and debottlenecking.
Phase 2 is expansion, not reinvention.
Separation Capacity Is the Real Scarcity
A persistent misunderstanding in rare earth markets is that ore availability is the main constraint. It isn’t.The bottleneck is:
- solvent extraction scale,
- chemical plant reliability,
- and consistent oxide specification.
- Expansion of an operating separation plant is far easier than building one from scratch.
- Customers value oxide certainty far more than upstream concentrate supply.
Also - the nolans deposit is 'open at depth'. This means that there could be much more scale to the deposit. During Phase 1, some additonal drilling will take place to determine the full extent of the deposit.
Why OEMs and Governments Care
Western automakers, defence agencies, and magnet manufacturers increasingly prioritise:- jurisdictional stability,
- ESG traceability,
- long-term contract reliability.
If Phase 2 proceeds:
- it strengthens non-China pricing benchmarks,
- improves supply diversification narratives,
- and reduces reliance on opaque Asian supply chains.
The Economic Flywheel Effect
Once Phase 1 is operational:- financing risk drops materially,
- technical performance becomes demonstrable rather than theoretical,
- customer confidence increases.
In additon, if Phase 1 can be commisioned, with little use of the contingencies, these monies could materially cover the additional capex for Phase 2 meaning if there was a need for any capital raise, it would be modest.
Also, we are not 100% clear what the US Govt's US$300 million is for? Presumably Phase 2? (it could be HREE related too?)
Why the Market May Be Underpricing ARU and Phase 2
Three reasons stand out:- Short-term financing focus — markets prioritise getting to FID and then construction risk over the Phase 2 expansion upside.
- Rare earth technical complexity — few analysts model solvent-extraction scale realistically.
- China dominance narrative — it suppresses appreciation of credible ex-China growth.
Bottom Line
Phase 1 establishes credibility.Phase 2 potentially reshapes relevance.
For those analysing future NdPr supply balance — particularly in magnet, EV, robotics, and defence sectors — the expansion pathway at Nolans is arguably one of the most consequential medium-term variables in the ex-China rare earth landscape.
And right now, it still appears materially under-reflected in market perception.
Let me know if you have any questions about Phase 2 (or anything else).
