Iondrive Eyes US$243M NPV From Single Rare Earth Module on Just US$11.9M Capex
Key Takeaways
- Iondrive's updated IONSolv™ evaluation returns a post-tax NPV of US$243m at a 10% real discount rate against development capital of just US$11.9m — a ratio that reflects the low capital intensity of the modular design, not conventional project economics.
- The 379% post-tax IRR and 0.24-year payback are driven by the assumption of no production ramp and full utilisation from day one, and are not comparable with returns reported for conventional development projects.
- Dysprosium oxide accounts for only 4.7% of modelled production by mass but approximately 49.5% of base-case revenue, making the assumed dysprosium content and the US$2,300/kg Western market price the single most material assumptions in the model.
- The feedstock grade of 30.66% REO — the primary driver of the economic improvement over the November 2025 study — is taken from assay of a commercial US magnet sample and has not yet been confirmed at commercial scale, which the CEO identifies as the pivotal risk.
- No pricing scenario tested in the model returns a negative post-tax NPV, with outcomes ranging from US$40m at a flat US$115/kg reference price to US$298m at 100% of Platts CIF North America assessments.
IONSolv™ rare earth module returns US$243m post-tax NPV on US$11.9m of development capital
Iondrive Limited has released results of an updated technical and economic evaluation for a single IONSolv™ module in the United States, with the study returning a post-tax NPV of US$243 million at a 10% real discount rate against development capital of just US$11.9 million. The contrast between those two figures is the central story. This evaluation supersedes the November 2025 study, applies IONSolv™ to the recovery of rare earth elements from end-of-life permanent magnets using deep eutectic solvent chemistry, and is a study — not a final investment decision.

Q1 FY27 module economics at a glance
The headline metrics for a single IONSolv™ module, as modelled in financial model version 0.7 dated 3 September 2026, are summarised below.
| Parameter | Updated Evaluation (Model v0.7) |
|---|---|
| Feedstock throughput | 2,402 tpa |
| REO head grade (assumed) | 30.66% |
| Annual revenue | US$121.8m |
| Annual EBITDA | US$62.1m |
| EBITDA margin | 51.0% |
| Development capital | US$11.9m |
| Post-tax NPV (10% real) | US$243m |
| Pre-tax NPV (10% real) | US$348m |
| Post-tax IRR | 379% |
| Post-tax payback | 0.24 years from first production |
| Operating life | 10 years following one construction year |
The 379% IRR and 0.24-year payback are a direct function of the low capital estimate, combined with model assumptions of no production ramp and full utilisation from day one. They are not comparable with returns reported for conventional development projects. One further figure demands attention: dysprosium oxide (Dy₂O₃) accounts for approximately 4.7% of modelled production by mass but approximately 49.5% of base-case revenue, making the assumed dysprosium content of the feed and the assumed dysprosium price both highly material to the result.
What changed from the November 2025 evaluation
The improvement in the economics is driven principally by the feedstock now being modelled, not by the process. The table below captures the key shifts.
| Parameter | November 2025 Evaluation | Updated Evaluation |
|---|---|---|
| Feedstock throughput (one module) | 2,000 tpa | 2,402 tpa |
| REO head grade | ~7.2% (implied) | 30.66% (assumed) |
| Dysprosium oxide share of contained REO | Not separately modelled | 4.45% |
| Dysprosium recovery | 32.1% (assumed) | 88.8% modelled; 93.5–93.6% validated |
| Payable oxide production | ~115 tpa | ~624 tpa |
The jump in payable oxide production from approximately 115 tpa to approximately 624 tpa is principally a function of the richer assumed feedstock, not improved recovery. As CEO Dr Grant Caffery states directly in the announcement, the critical risk sits with the feedstock: its grade of 30.66% REO is taken from assay of a commercial US magnet feedstock sample, and confirmation of that grade and its availability at commercial scale remains the pivotal work ahead.
Understanding IONSolv™ — why recycling magnets matters for the US critical minerals supply chain
IONSolv™ is a metal extraction platform built on deep eutectic solvent (DES) chemistry. DES is a type of solvent formed by combining two or more compounds that, together, have a much lower melting point than either ingredient separately. Applied to end-of-life permanent magnets, IONSolv™ selectively dissolves and extracts rare earth elements at lower temperatures and without the aggressive acid systems used in conventional hydrometallurgical processing.
The rare earth elements being recovered — neodymium (Nd), praseodymium (Pr) and dysprosium (Dy) — are critical inputs to the high-strength permanent magnets used in electric vehicles, defence systems, industrial robotics and clean energy equipment. These magnets cannot currently be made without them.
The supply chain problem is straightforward: rare earth separation and refining capacity is heavily concentrated offshore, and US manufacturers in defence, automotive, robotics and clean energy are actively seeking secure, traceable domestic supply. IONSolv™ addresses this by processing end-of-life magnet waste inside the United States, close to where that waste arises.
The modular design is a commercial advantage. Capacity can be added in increments, sited near magnet waste sources, with a low capital entry point per module. Each module is a discrete investment decision, which limits upfront exposure and allows the strategy to scale as feedstock supply and customer demand develop.
Recovery assumptions and pricing basis
Modelled recoveries versus validated testwork
The economic model applies assumed overall flowsheet recoveries that sit below the independently validated single-pass leach results:
- Nd₂O₃: Validated 96.5% → Modelled 89.3%
- Pr₆O₁₁: Validated 96.5–97.3% → Modelled 88.5%
- Dy₂O₃: Validated 93.5–93.6% → Modelled 88.8%
The gap exists because the validated figures cover single-pass leach only. The modelled figures incorporate element-specific assumptions for recovery through downstream flowsheet stages, and those downstream assumptions have not yet been validated through integrated testwork. Planned bulk and integrated testwork is intended to test recovery through to final product.
Pricing assumptions
The three pricing inputs, applied at 90% realisation, are:
- Nd₂O₃: US$115/kg benchmark → US$103.50/kg realised
- Pr₆O₁₁: US$115/kg benchmark → US$103.50/kg realised
- Dy₂O₃: US$2,300/kg benchmark → US$2,070/kg realised
These benchmark assumptions are management-adopted figures referenced to Platts (S&P Global Commodity Insights) CIF North America assessments, giving a blended realised value of US$193 per kilogram of product. They are modelling inputs, not independently determined price forecasts, and no sales price is contracted and no offtake agreement has been executed.
The dysprosium pricing separation is material. The base case uses an ex-China Western market level of US$2,300/kg. By comparison, the Chinese domestic assessment published by Shanghai Metals Market (SMM) stands at US$191/kg — a stark difference that underpins the significance of Western market access to the economics.
Sensitivity analysis shows robust economics across pricing scenarios
No pricing case tested in the model returns a negative post-tax NPV. The range of outcomes across the pricing scenarios modelled is:
- Flat US$115/kg reference: US$40m
- Illustrative floor pricing: US$80m
- 170% of Chinese domestic (SMM) assessments: US$200m
- Base case — 90% of Platts CIF North America: US$243m
- 100% of Platts CIF North America: US$298m
The variable sensitivity analysis reinforces where the risk actually sits. A 30% move in realised product price shifts post-tax NPV from US$130m to US$355m. A 30% move in development capital moves NPV only from US$247m to US$238m — confirming that the project economics are fundamentally driven by feedstock quality and pricing assumptions, not by capital intensity. Confirming feedstock grade and availability at commercial scale is the pivotal de-risking step.
CEO commentary
Dr Grant Caffery, Chief Executive Officer, Iondrive Limited
“The number that matters most in this study is not the rate of return. It is the feedstock. The economics assume material at 30.66% REO, and confirming grade and availability at commercial scale is the work in front of us…”

Next steps toward a first commercial module in Oklahoma
The company has outlined four concrete steps between now and a final investment decision:
- Complete front-end engineering design and refine capital and operating cost estimates for a first commercial module.
- Complete the US commercial-scale qualification campaign and confirm feedstock grade, composition and availability.
- Progress US site selection, permitting and approvals.
- Advance feedstock supply, product offtake and funding arrangements toward a final investment decision.
The announcement notes that construction of a commercial module requires funding, site selection, permitting and approvals, and a final investment decision, none of which is assured. The modular design means multiple modules could follow if feedstock supply and customer demand support it. The US$243m post-tax NPV is modelled for one module only — the strategy contemplates deployment of additional modules as conditions allow.
