Hastings Technology Metals and JV partner Wyloo have unveiled an updated Definitive Feasibility Study for the Yangibana Rare Earths Project, revealing robust economics and a streamlined path to production with substantial infrastructure already in place.
- Pre-tax NPV8 of A$649 million and 34% IRR for Stage 1
- 19-year mine life fully supported by Proved and Probable Ore Reserves
- Capital cost of A$333.4 million with significant infrastructure delivered
- Annual rare earth concentrate production of up to 37,000 tonnes at 27% TREO
- Wyloo initiates sale process for its 60% JV interest amid strong market interest
Robust Economics Back Capital-Efficient Stage 1 Development
Hastings Technology Metals (ASX:HAS) and joint venture partner Wyloo Gascoyne have released an updated Definitive Feasibility Study (DFS) for Stage 1 of the Yangibana Rare Earths and Niobium Project in Western Australia's Upper Gascoyne region. The study confirms a pre-tax NPV8 of A$649 million and an impressive 34% internal rate of return (IRR), underpinned by a 2.4-year payback period from first production.
The project centres on a straightforward open pit mining operation coupled with a conventional beneficiation plant designed to produce a rare earth concentrate. Stage 1 targets a 19-year mine life, fully supported by 20.93 million tonnes of Ore Reserves grading 0.90% total rare earth oxides (TREO), with no reliance on Inferred Resources. Peak annual concentrate production is projected at 37,000 tonnes at 27% TREO grade, featuring a world-class neodymium-praseodymium (NdPr) content that accounts for 37% of contained TREO and over 90% of forecast revenue.
Substantial Infrastructure and Capital Discipline Reduce Execution Risk
A key advantage for Yangibana is the significant infrastructure already in place following prior construction activities between 2022 and 2024. This includes a 294-room accommodation village, a 1,800-metre airstrip, main access roads, and a fully commissioned raw water borefield. Equipment for the beneficiation plant has also been procured, lowering capital risk and shortening the timeline to first production.
The total Stage 1 capital cost is estimated at A$333.4 million, inclusive of growth and contingency allowances, delivering a strong NPV to capital expenditure ratio of 1.94. Operating costs are competitive, with a life-of-mine all-in sustaining cost (AISC) of A$25.57 per kilogram of TREO in concentrate. Average annual EBITDA is forecast at A$108 million, generating a total life-of-mine EBITDA of over A$2 billion.
JV Dynamics and Sale Process Signal Strategic Interest
The Yangibana Project is held through the Yangibana Joint Venture (YJV), with Wyloo Metals owning 60% and Hastings holding 40%. Wyloo has commenced a sale process for its majority interest, attracting strong interest from both domestic and international parties recognising the project's potential as a near-term rare earth concentrate producer. This sale process unfolds as the YJV advances towards a Final Investment Decision (FID), contingent on securing project financing.
Wyloo’s CEO, Luca Giacovazzi, emphasised the project’s capital-light profile and short runway to production, highlighting the benefit of prior infrastructure investments. Hastings CEO Vince Catania echoed confidence in Yangibana’s readiness, noting the Ore Reserve is fully supported by Proved and Probable classifications and the project’s robust economics.
Market Fundamentals and Downstream Optionality
The DFS assumes a US$110/kg price floor for NdPr oxide, reflecting recent US government policy measures supporting diversified rare earth supply chains. With global demand for magnet rare earth elements projected to rise significantly through 2040, driven by electric vehicles, renewable energy, and defence applications, Yangibana is strategically positioned to capitalise on these trends.
While Stage 1 focuses on producing rare earth concentrate for sale to third parties, the YJV retains optionality for Stage 2 downstream hydrometallurgical processing to produce mixed rare earth carbonate (MREC). This downstream pathway remains under separate evaluation and is not included in the current DFS economics. Hastings’ recent acquisition of a 49% stake in a Thai hydrometallurgical plant complements this strategy, providing a near-term, capital-efficient route to refined products and cash flow ahead of Yangibana’s production start.
Path to Production and Remaining Challenges
The updated schedule targets first concentrate production approximately two years after awarding the process plant EPC contract. Early works are recommended to recommission existing facilities and order remaining long lead items. The project is fully permitted, with all primary statutory consents secured and approvals for years 9 to 19 of the mine plan under assessment.
Key risks include securing project financing, managing mining dilution and pit wall stability, and maintaining environmental and safety standards. The YJV is actively engaging with lenders and investors, targeting a minimum 50% project gearing. Hastings is also exploring strategic investments and government-backed financing to reduce its equity contribution.
Bottom Line?
Yangibana’s updated DFS cements its status as a robust, de-risked rare earth project with strong economics and infrastructure advantages, but financing and JV ownership changes will be critical next steps.
Questions in the middle?
- How will the sale of Wyloo’s 60% JV interest impact project timelines and strategic direction?
- What financing structures and partners will the YJV secure to underpin the Final Investment Decision?
- How might downstream processing options evolve to enhance value beyond Stage 1 concentrate production?
