Arafura began extensive metallurgical testwork to find a processing method that works for Nolans’ rare-earth-and-phosphate ore. This early technical work mattered because later feasibility studies and financing depended on proving the ore could be processed reliably at industrial scale.
Arafura launched a larger demonstration program to reduce “scale-up risk,” meaning the risk that a process that works in a lab fails when built bigger. Bulk ore was extracted to generate representative samples and test the proposed flowsheet (the step-by-step processing design).
Arafura announced an institutional placement to raise about A$90 million to support a bankable feasibility study and regulatory approvals. This was a key step because feasibility and permitting are prerequisites for project financing and a final build decision.
AMEC Minproc was contracted to perform a bankable feasibility study for Nolans. Engineering-led feasibility work helps convert resource potential into a buildable project plan, including plant design, costs, and execution strategy.
Arafura delayed its bankable feasibility study by roughly 9–12 months after expanding the study’s scope to reduce costs and start-up risks. The change showed the project design was still evolving, which can improve long-term economics but often extends schedules.
The Northern Territory government granted Nolans “major project status,” a designation intended to support coordination and streamline some government interactions. This mattered because large mines face complex approvals and infrastructure planning across multiple agencies.
The Northern Territory Environment Protection Authority (NT EPA) completed its environmental impact assessment and concluded the project could be managed to avoid unacceptable impacts if conditions were met. Key issues included waste with naturally occurring radioactive materials, groundwater abstraction, and creek diversion.
Australia’s federal environment department approved the project under the EPBC Act, subject to conditions. This was a major regulatory milestone because federal approval is often required before final mining and construction approvals can proceed.
Arafura released the results of its Definitive Feasibility Study (DFS) for Nolans. The DFS set out a detailed technical and cost plan to mine and process ore into separated rare earth oxides, forming a core basis for later project updates and financing discussions.
After project configuration changes, Arafura submitted a Section 14A variation, which the NT EPA reviewed and determined required no further environmental assessment action. This helped keep permitting aligned with the evolving project design without restarting the full EIS process.
Arafura executed a Native Title agreement for the Nolans area. Such agreements are important because they set terms for land access, cultural heritage protections, and benefits, helping reduce legal and social risk during construction and operations.
Arafura published an updated feasibility study and project update, reflecting changes in costs, design, and execution planning. Updates like this matter because lenders and offtake partners typically require current, detailed assumptions before committing funding.
Arafura awarded an Engineering and Procurement (EP) contract to Hatch to complete front-end engineering design (FEED) work. FEED is a detailed design stage used to tighten cost estimates and prepare tendering for full Engineering, Procurement, and Construction (EPC) contracts.
The Northern Territory issued a Mining Authorisation for the project. This was a key step toward being “construction ready,” because it supports moving from studies and approvals into permitted on-the-ground mining activity once financing and final investment decisions are in place.
Arafura signed a binding offtake agreement with Hyundai and Kia for NdPr (neodymium-praseodymium) product. Offtake contracts help projects secure financing by showing future customers and expected sales volumes.
The Northern Territory granted a groundwater extraction licence for Nolans. Water access is a core operational requirement for mining and hydrometallurgical processing, so this approval reduced a major enabling risk for construction and operations planning.
APA Group and Arafura signed an agreement to start early works for a planned cogeneration power plant to supply energy to Nolans. Securing a credible power solution is critical for rare earth separation because processing plants require steady electricity and steam.
Government project listings reported early construction works were completed in 2023. These early packages (such as site access, communications, and enabling infrastructure) are often done ahead of full construction to shorten the schedule once a final investment decision is made.
The Northern Australia Infrastructure Facility (NAIF) made an investment decision to provide up to A$200 million in project finance for Nolans. This was a significant financing milestone because it indicated government-backed infrastructure funding support tied to regional development goals.
Reports and public summaries described a major debt financing package for Nolans linked to Australia’s Critical Minerals Facility, including NAIF participation. This mattered because large rare earth projects typically need blended funding (government-linked and commercial) to manage construction and market risks.
Arafura executed a binding term sheet for A$200 million of convertible notes with Australia’s National Reconstruction Fund Corporation. This supported the funding mix by adding a quasi-equity instrument (debt that can convert to shares), often used to bridge capital gaps in strategic projects.
Arafura added a binding offtake agreement with Traxys Europe SA, expanding the set of committed customers. Multiple offtake counterparties can reduce single-buyer risk and strengthen lender confidence in projected sales.
Arafura and Tamboran signed a non-binding letter of intent for gas supply, aimed at supporting reliable energy for operations. Energy planning remained central because rare earth separation and associated processing require stable, long-duration utilities contracts.
Export Finance Australia provided conditional support for a US$100 million equity investment in the Nolans project. This was important as equity is often the hardest portion to secure, and export credit support can signal strategic value for downstream supply chains.
By early 2026, reporting indicated Arafura was targeting the first half of 2026 for a final investment decision (FID), later than earlier targets. The delay was linked to the time needed to finalize negotiations with potential equity partners, showing financing completion remained the main gating factor.
