Vanadium Resources Scoping Study Flags US$842M NPV for Dual Iron and Vanadium Project
Key Takeaways
- The Steelpoortdrift V-Iron Scoping Study returns a base case post-tax NPV of US$842m and a 36% IRR, with a 2.4-year payback from first production — preliminary figures subject to ±30% CAPEX/OPEX accuracy.
- The dual-revenue model produces approximately 603,000 tonnes per annum of pig iron and approximately 17,300 tonnes of contained V₂O₅ per year via vanadium-rich slag, reducing single-commodity price exposure relative to VR8's previous hydrometallurgical approach.
- 100% of planned vanadium-slag output is covered by a non-binding offtake term sheet with U.S. Vanadium Holding Company LLC, which has already confirmed the slag's suitability through test work at its own refinery.
- Pre-production CAPEX is estimated at approximately US$400m under a proposed 60/40 debt-to-equity structure, with a base case minimum DSCR of 3.5x — well above the 1.3x–1.4x project finance threshold — though funding availability is not certain.
- RMB has been appointed as exclusive financial adviser, and VR8 completed a U.S. institutional roadshow in late September 2026, with the next milestone being funding for a US$3m V-Iron Definitive Feasibility Study.
Scoping study validates V-Iron pathway with US$842m NPV and dual-revenue model
Vanadium Resources Limited (ASX: VR8) has completed a Scoping Study assessing the proposed development of an integrated vanadium and iron co-production operation based on the Steelpoortdrift Project in Limpopo, South Africa. The Study evaluates a V-Iron Plant concept that would simultaneously produce pig iron and vanadium-rich slag from the same feedstock — a dual-revenue approach that the company believes offers a more robust development pathway than its previous processing strategy.
VR8 holds an 86.49% interest in the Steelpoortdrift Mining Project and a 100% interest in VR8 Highveld, the subsidiary through which the V-Iron Plant is proposed to be developed. All figures in the Study are reported on a 100% project basis, without adjustment for VR8’s ownership interests.
Under the Base Case (priced at 2016–2025 real median prices held flat in real terms), the Study estimates the following preliminary outcomes, subject to ±30% CAPEX/OPEX accuracy:
- Post-tax NPV₁₀: approximately US$842m
- Post-tax IRR: approximately 36%
- Average annual EBITDA: approximately US$226m
- Average annual free cash flow: approximately US$164m
- Post-tax payback from first production: approximately 2.4 years
At current spot prices (pig iron approximately US$486/t FOB Brazil; V₂O₅ approximately US$5.36/lb), the Study estimates a post-tax NPV of approximately US$665m and an IRR of approximately 31%. Subject to funding, the Study supports progression to a V-Iron Definitive Feasibility Study (DFS).

What is vanadium-iron co-production and why does it matter?
The V-Iron process begins with vanadium titanomagnetite (VTM) concentrate mined from an open pit at Steelpoortdrift. That concentrate is transported approximately 190 kilometres by road to Highveld Industrial Park, where it is pre-treated and smelted in a DC electric arc furnace — a type of high-powered electric furnace that melts the material at extreme temperatures. The smelting process separates the feed into two distinct saleable streams: pig iron (a steelmaking input) and vanadium-rich slag (an intermediate product refined into vanadium pentoxide, vanadium nitride, or ferro-vanadium, which are key inputs for high-strength steel and vanadium flow batteries).
This differs meaningfully from VR8’s previous approach. The 2022 Definitive Feasibility Study assessed a hydrometallurgical salt roast leach (SRL) process that produced vanadium pentoxide directly, with no iron revenue. The V-Iron route adds pig iron as a second substantial revenue stream, reducing the project’s dependence on vanadium prices alone.
The process is not unproven technology in a new configuration. It draws directly on industrial experience at New Zealand Steel and the former Highveld Steel and Vanadium operations in South Africa, though the proposed configuration for Steelpoortdrift remains subject to metallurgical test work and process optimisation during the V-Iron DFS.
For readers wanting to understand the technical leadership and process design decisions that shaped these results, our dedicated guide to the pyrometallurgical expertise behind the Scoping Study covers the appointment of the lead metallurgist and the key design parameters she established for the DC arc furnace configuration.
The nameplate production targets are approximately 603,000 tonnes per annum of pig iron and approximately 65,000 tonnes per annum of vanadium-rich slag grading approximately 26.7% V₂O₅ (containing approximately 17,300 tonnes of contained V₂O₅ per year).
Why the U.S. connection matters
The entire planned vanadium-rich slag output is covered by a non-binding offtake term sheet with U.S. Vanadium Holding Company LLC (USV), covering 100% of planned production. USV has already completed test work on a historic Highveld-equivalent slag sample at its own refinery, confirming its suitability as feedstock for USV’s refining process. The flowsheet was explicitly designed to target a slag composition near-identical to what Highveld Steel historically produced, anchoring the Steelpoortdrift product to a specification already proven in the offtaker’s circuit.
The U.S. Vanadium offtake arrangement covers the full vanadium-slag volume and was structured around a slag composition near-identical to what Highveld Steel historically produced, giving USV confidence that the Steelpoortdrift product would integrate directly into its existing refinery circuit.
The geopolitical dimension is significant for project financing. The supply route moves vanadium directly from South Africa to a U.S. refinery without transiting adversarial jurisdictions, aligning with U.S. critical mineral supply chain priorities. This transparent route to market is considered a material factor in pursuing development finance institution (DFI) support.
Project economics across three price scenarios
The Study estimates financial outcomes across low, base, and high commodity price scenarios, each drawn from the real price history of the past 20 years. These are preliminary outcomes with ±30% accuracy, and simultaneous adverse movements across multiple assumptions could produce materially lower outcomes than shown in the single-variable sensitivities.
| Scenario | Pig Iron Price (FOB Brazil) | V₂O₅ Price | Post-Tax NPV | Post-Tax IRR |
|---|---|---|---|---|
| Low Case | ~US$330/t | ~US$4.55/lb | ~US$53m | ~13% |
| Base Case | US$456/t | US$7.86/lb | ~US$842m | ~36% |
| Current Prices | ~US$486/t | ~US$5.36/lb | ~US$665m | ~31% |
| High Case | ~US$740/t | ~US$10.00/lb | ~US$2.01bn | ~63% |
The Study notes that estimated project NPV remains positive across all individual ±30% sensitivities applied to exchange rates, pig iron prices, vanadium prices, and slag-payability assumptions. Financial outcomes are most sensitive to the exchange rate and pig iron price, followed by the vanadium price. Under the Low Case, the estimated minimum debt service coverage ratio falls to approximately 0.96x, and the assumed debt structure would not be serviceable without mitigation.
Capital structure and debt servicing capacity
Pre-production CAPEX is estimated at approximately US$400m (inclusive of contingency; ±30% accuracy). The breakdown of capital items is as follows:
- Smelting plant and DC furnace: approximately US$170m
- Pre-treatment plant: approximately US$104m
- Infrastructure, EPCM and owner’s costs: approximately US$62m
- Concentrator: approximately US$39m
- Contingency: approximately US$25m
Under the Base Case, the Study estimates a minimum debt service coverage ratio (DSCR) of approximately 3.5x, well above the 1.3x–1.4x minimum typical of project finance. The Study assumes an indicative evaluation structure of 60% project debt / 40% equity, with the majority of development funding expected to comprise project debt, supplemented by DFI funding and grants. There is no certainty that funding will be available when needed.

Executive commentary and the path to DFS
Executive Chairman Jurie Wessels
“This Scoping Study provides compelling preliminary validation for our decisive pivot to a pyrometallurgical co-production process, which we believe offers greater robustness, reliability and long-term optimisation than the hydrometallurgical methods presently relied upon by most western-hemisphere vanadium producers… Positioning VR8 to produce vanadium slag could make VR8 one of the few, and potentially the only, long-term, reliable suppliers of consistent VTM-derived raw material of significant volume to the U.S. market through our growing relationship with U.S. Vanadium.”
CEO Nick Diack
“Our developing U.S. Vanadium offtake partnership anchors 100% of planned vanadium-slag production in Western critical-mineral supply chains, with a usable intermediate product moving directly from South Africa to a U.S. refinery without passing through, or depending on, any adversarial jurisdiction. That secure and transparent route to market enhances the strategic value of Steelpoortdrift and, in our view, makes financing considerably more achievable with development finance institutions and partners holding critical-minerals mandates.”
Immediate priorities and next steps
VR8 is pursuing the following workstreams following the completion of the Scoping Study:
- Securing funding for the V-Iron DFS, estimated at approximately US$3m (indicative cost, excluding owner’s costs, environmental studies, contingencies, and costs towards Final Investment Decision and Front-End Engineering Design), from U.S. and other development finance institutions and strategic equity partners. RMB has been appointed as exclusive financial adviser and capital sourcing agent.
- Progressing the USV non-binding offtake term sheet toward a binding arrangement covering 100% of vanadium-slag production.
- Confirming site tenure at Highveld Industrial Park, where VR8 holds a right of first refusal over suitable portions of the property; definitive lease and utility agreements are to be concluded.
- Evaluating renewable energy and behind-the-meter solutions to reduce the operating cost base, including a potential vanadium flow battery partnership that could create a closed-loop energy solution at the site.
- Securing pig iron offtake arrangements with South African steel producers or international markets.
VR8 recently completed a U.S. institutional roadshow during the week commencing 28 September 2026, engaging development finance institutions, strategic partners, and government agencies.
