Hastings Technology Metals Ltd (HAS) has released an updated Definitive Feasibility Study (DFS) for Stage 1 of its Yangibana rare earths and niobium project in Western Australia. The study highlights a capital-efficient, de-risked development strategy centered on conventional open-pit mining and whole-of-ore flotation. With a 19-year mine life fully supported by ore reserves, the project is positioned to produce a rare earth concentrate rich in neodymium-praseodymium (NdPr), which accounts for the vast majority of projected revenue.

The economic profile for the project indicates a pre-tax net present value of A$649M, supported by a 34% pre-tax internal rate of return and a 2.4-year payback period from the commencement of production. The initial capital expenditure is estimated at A$333.4 million. A significant portion of the development risk is mitigated by existing site infrastructure, including an accommodation village, airstrip, and completed borefields.

"This updated DFS confirms what we have long believed about Yangibana , that it is one of the highest-grade NdPr rare earths deposits in the world, and it is ready to be built. Much of the heavy lifting is already done: the village, airstrip, access roads and borefields are in place, our Ore Reserve is fully supported by Proved and Probable classifications, and our mining and processing assumptions have been refreshed to reflect current conditions. A 2.4-year payback and $108 million of average annual EBITDA over a 19 -year mine life speaks for itself." — Vince Catania, Chief Executive Officer

The project is held through the Yangibana Joint Venture between Hastings and Wyloo Gascoyne Pty Ltd. Following the release of the updated study, a formal sale process has commenced for the 60% interest currently held by Wyloo. This transition marks a notable change in the ownership structure of the project as it moves closer to a final development decision.

The path forward hinges on several upcoming milestones necessary to advance the project toward its target production date. These catalysts include reaching a Final Investment Decision (FID) and the subsequent award of the engineering, procurement, and construction (EPC) contract for the process plant. Once the EPC contract is awarded, the project schedule estimates a timeline of approximately two years to achieve first concentrate production. With all environmental and statutory approvals already secured, the joint venture partners are focused on leveraging the completed infrastructure to accelerate the transition from the current development phase to an operational mining enterprise.
