HyProMag USA PFS: economics and design takeaways for magnet project engineers

30 Second Briefing
HyProMag USA’s pre-feasibility study for a three-plant expansion plus a Central Texas manufacturing and technology hub projects post-tax NPV of $1.85–$2.1 billion and post-tax IRR of 31–36% on Class 3 capex of $623–$656 million, with payback in 2.3–3 years. Together with the Northlake, Texas plant now in detailed engineering and targeting mid-2028 commissioning, the platform aims for about 6,000 t/y of salable NdFeB products by 2034, including 4,192 t/y of finished magnets. Forecast 2030 AISC of $37.4–$41.6/kg versus a weighted average selling price of ~$100.5/kg signals robust margins for a mixed primary and recycled feedstock model.
Technical Brief
- PFS covers three new regional NdFeB production plants plus a Central Texas manufacturing/finishing/technology hub.
- AISC for the first PFS plant explicitly includes all downstream finishing, plating and epoxy coating operations.
- Profitability index for the three new plants is estimated at ~2.8x–3.3x, indicating strong value per capex dollar.
- Feedstock flexibility is designed in from the outset, combining end‑of‑life recycled magnets with primary NdFeB alloy.
- For other magnet or battery metals projects, similar mixed primary–recycled feed models could de‑risk supply volatility and pricing exposure.
Our Take
With phase‑1 commissioning only expected by mid‑2028, HyProMag USA’s build‑out lags several upstream rare earth mine projects in the United States in our database, implying potential alignment as a mid‑stream offtake outlet once domestic REE supply from those mines begins to ramp.
