V-Iron Plant Economics
Vanadium Resources Study Projects $842M NPV for South African V-Iron Plant
Anonymous
Key Points
1
Using current spot prices of about US$486 per tonne for pig iron and US$5.36 per pound for V₂O₅, rather than the base case’s historical price assumptions, the study indicates a lower post-tax NPV of US$665 million and an IRR of 31%.
2
The base case uses 2016–2025 real median prices of US$456 per tonne for pig iron (FOB Brazil) and US$7.86 per pound for vanadium pentoxide (Rotterdam 98%); the vanadium-slag model assumes 50% payability against the V₂O₅ reference price, subject to negotiation.
3
The proposed process would pre-reduce material to about 82% metallisation, smelt it in a nominal 55 MW open-bath DC furnace, then recover vanadium through oxidative blowing. The design draws on industrial precedents at New Zealand Steel and the former Highveld Steel and Vanadium operations.

The Steelpoortdrift mining project is 86.49% owned by Vanadium Resources, while the V-Iron plant would be wholly owned through subsidiary VR8 Highveld. The proposed Highveld Industrial Park site has established electricity, water and rail infrastructure, and the company holds a right of first refusal over portions of the site.

The 30-year evaluation estimates post-tax payback at 2.4 years from first production, average annual free cash flow of US$164 million during production, and cumulative free cash flow of US$4.4 billion.
Vanadium Resources' scoping study projects an $842 million net present value for a proposed V-Iron plant at South Africa's Steelpoortdrift project, according to Mining Weekly. The operation would combine an open-pit mine and concentrator with a smelting facility at Highveld Industrial Park, producing about 65,000 tonnes of vanadium-rich slag and 603,000 tonnes of pig iron annually. The base case assumes a 36% internal rate of return with $400 million in pre-production capital.
Current spot prices paint a more conservative picture. At today's rates of $486 per tonne for pig iron and $5.36 per pound for vanadium pentoxide, the post-tax NPV drops to $665 million with a 31% internal rate of return, Mining Weekly reported. The company plans to move forward with a feasibility study costing roughly $3 million before pursuing a final investment decision.
Base Case Economics Built on Historical Prices
The $842 million NPV estimate relies on 2016–2025 real median prices: $456 per tonne for pig iron and $7.86 per pound for vanadium pentoxide, according to Grafa. The vanadium-slag model assumes 50% payability against the vanadium pentoxide reference price, a figure subject to negotiation. Over a 30-year evaluation period, the project shows post-tax payback in 2.4 years and average annual free cash flow of $164 million during production.
These numbers carry roughly ±30% accuracy and don't guarantee the project will be profitable, Mining Weekly cautioned. No ore reserve has been formally established for the V-Iron process yet. The economics also hinge on a non-binding term sheet covering vanadium-slag sales to a U.S. buyer.
Industrial Process Uses Pre-Reduction and DC Smelting
The V-Iron plant would pre-reduce material to about 82% metallisation before smelting it in a nominal 55 MW open-bath DC furnace, according to Mining Weekly. The design draws on proven methods from New Zealand Steel and the former Highveld Steel and Vanadium operations. After smelting, vanadium recovery happens through oxidative blowing, creating the vanadium-rich slag product.
This approach replaces the salt roast leach method examined in Vanadium Resources' 2022 feasibility study. The shift signals the company's confidence in the co-production model for serving U.S. and allied markets with reliable vanadium supply, Mining Weekly reported.
Site Infrastructure and Ownership Structure in Place
Vanadium Resources owns 86.49% of the Steelpoortdrift mining project, while the V-Iron plant would be wholly owned through subsidiary VR8 Highveld, Grafa noted. The proposed Highveld Industrial Park location has established electricity, water, and rail infrastructure already in use. The company holds a right of first refusal over portions of the site, giving it leverage in negotiations.
The cumulative free cash flow projection over 30 years reaches $4.4 billion under base case assumptions. However, the company will need substantial project financing to move past the feasibility study phase and reach a final investment decision, Mining Weekly reported.
Next Steps: Feasibility Study and Capital Raise
The $3 million feasibility study represents the next major milestone for Vanadium Resources. Completion would pave the way for project financing discussions and an eventual final investment decision. The scoping study's preliminary nature means many technical and commercial details remain to be finalized during this phase.
The project's strategic appeal rests on securing long-term vanadium supply for U.S. and allied nations, Mining Weekly noted. With established infrastructure at the Highveld site and proven smelting technology, the pathway from scoping to full operation appears clearer than some competing vanadium ventures. Financing remains the critical hurdle.
