Aclara Completes Basic Engineering for Its U.s. Heavy Rare Earths Separation Facility in Louisiana

Aclara advances US rare earths project but faces high costs and long timelines.

What the company is saying

Aclara Resources Inc. is highlighting the completion of basic engineering for Project Dynamo, its planned heavy rare earths separation facility in Louisiana, as a major milestone toward construction. The company frames this as a defining step, emphasizing technical progress, improved metallurgical recoveries, and expanded production capacity, now targeting six high-purity rare earth oxides. Management, including COO Hugh Broadhurst and CEO Ramón Barúa, stress the project's scale, traceable feedstock, and integration with upstream assets in Chile and Brazil. The announcement underscores the facility's non-radioactive, non-regulated status, permitting achievements, and a substantial US$46.4 million incentive package from Louisiana. Aclara also spotlights a non-binding EXIM Letter of Interest for up to US$750 million in financing and the role of its Virginia Tech demonstration plant and AI-enabled process optimization. The tone is confident, with repeated references to strategic importance, customer demand, and supply chain resilience, but the company is clear that execution depends on future financing and successful project delivery.

What the data suggests

The announcement provides detailed project economics and technical metrics. The capital cost estimate (Capex) has risen to US$494 million from US$277 million, reflecting a significant expansion in scope, including 42% higher Dy and Tb separation capacity and three new separation circuits for Y, Gd, and Sm. Operating cost estimates (Opex) have improved, dropping by 32% to US$26/kg from US$38/kg, excluding feedstock. Metallurgical recoveries are now estimated at ~97.9% for Dy, ~97.7% for Tb, ~85.7% for Y, ~86.7% for Gd, ~96.3% for Sm, and ~98.9% for NdPr, all at high-purity levels (≥99.5%). Targeted average annual production at full capacity is Dy oxide ~200 tonnes, Tb oxide ~35 tonnes, Y oxide ~1,350 tonnes, Gd oxide ~180 tonnes, Sm oxide ~190 tonnes, and NdPr oxide ~1,300 tonnes. The project is projected to deliver an after-tax NPV of US$773 million at an 8.0% discount rate, an IRR of 27.9%, and a 2.6-year payback. Permitting is advanced, with the key air permit secured in September 2026. The EXIM Letter of Interest for up to US$750 million is non-binding and subject to due diligence. The demonstration plant at Virginia Tech has validated NdPr oxide production, with Dy and Tb targeted for Q4 2026, and further expansion underway. Most figures are projections, with actual construction and production still years away.

Analysis

The announcement is detailed and provides credible evidence of progress, notably the completion of basic engineering, improved metallurgical recoveries, and the achievement of key permitting milestones. However, the majority of the headline claims—such as targeted production volumes, project economics (NPV, IRR), and the start of site preparation—are forward-looking and contingent on securing nearly US$500 million in capital, with construction not expected to complete until H2 2028. The EXIM financing is only at the Letter of Interest stage and is non-binding, meaning funding is not yet secured. While the reduction in Opex and improved recoveries are positive, these are projections rather than realised operational results. The capital intensity is high, and the timeline for benefit realisation is long-term, with no immediate earnings impact. The tone is optimistic, but the gap between narrative and realised progress is material, as most benefits are years away and dependent on future financing and execution.

Risk flags

• ●Financing risk is high, as the US$494 million Capex is not yet secured and the EXIM Letter of Interest is non-binding, requiring further due diligence and approvals. Failure to obtain full funding would delay or jeopardize project execution.
• ●Execution risk is significant due to the project's technical complexity, long construction timeline, and the need to integrate new separation circuits for multiple rare earth elements. Any delays in engineering, procurement, or construction could push back the H2 2028 completion target.
• ●Market risk exists because the project's economics rely on Argus Media pricing assumptions and sustained demand for heavy rare earths. Any downturn in rare earth prices or changes in global trade policy could materially impact projected NPV and IRR.
• ●Operational risk remains as the Virginia Tech demonstration plant has only validated NdPr production so far, with Dy and Tb oxide production and new circuits for Y, Gd, and Sm still to be proven at scale. If recoveries or purities are not achieved as projected, output and economics could suffer.
• ●Permitting and regulatory risk, while mitigated by the recent air permit, persists for other required approvals and for the upstream feedstock projects in Chile and Brazil, which must deliver SPREC at scale and on schedule.

Bottom line

Aclara’s completion of basic engineering for Project Dynamo marks real progress, with improved technical metrics and a clearer path to construction, but the project remains at a pre-construction stage with substantial execution hurdles. The US$494 million capital requirement is high, and while the EXIM Letter of Interest for up to US$750 million is a positive signal, it is not a funding commitment. Projected economics—US$773 million NPV, 27.9% IRR, and a 2.6-year payback—are attractive, but depend on successful financing, construction, and ramp-up, none of which are guaranteed. The demonstration plant has validated only part of the product slate, and the first commercial output is at least two years away. Investors should treat the narrative as credible on technical progress but recognize that most benefits are long-dated and contingent on future milestones. The most important takeaway is that Aclara is moving forward, but the investment case hinges on securing funding and delivering on ambitious technical and operational targets.

Announcement summary

(TSX:ARA) Aclara Resources Inc. announced the completion of basic engineering for its planned heavy rare earths separation facility, Project Dynamo, in Louisiana, United States. The basic engineering was completed by Hatch Ltd. and establishes the technical basis for detailed engineering, procurement, and construction. Project Dynamo is designed to process super-pure mixed rare earth carbonate (SPREC) from Aclara's ionic clay projects in Chile and Brazil, producing high-purity separated rare earth oxides including dysprosium (Dy), terbium (Tb), yttrium (Y), gadolinium (Gd), samarium (Sm), and neodymium-praseodymium (NdPr). Site preparation is targeted to commence in Q1 2027, subject to financing and other customary conditions, with construction completion targeted in H2 2028. The facility is specifically designed to process Aclara's SPREC, which is considered non-radioactive and non-regulated for shipment and processing in all jurisdictions where Aclara operates, as confirmed by independent laboratory testing by SGS Lakefield. Aclara's demonstration facility at the Virginia Tech Corporate Research Center has already produced NdPr oxide to target specifications, with Dy and Tb oxide production targeted for Q4 2026. Metallurgical recovery estimates have improved: Dy to ~97.9% (from 95%) with 99.5% purity, Tb to ~97.7% (from 95%) with 99.9% purity, Y to ~85.7% with 99.9% purity, Gd to ~86.7% with 99.9% purity, Sm to ~96.3% with 99.5% purity, and NdPr to ~98.9% (from 95%) with 99.5% purity. Targeted average annual production at full capacity is: Dy oxide ~200 tonnes (previously 140 tonnes), Tb oxide ~35 tonnes (previously 25 tonnes), Y oxide ~1,350 tonnes (new), Gd oxide ~180 tonnes (new), Sm oxide ~190 tonnes (new), and NdPr oxide ~1,300 tonnes (previously 1,100 tonnes). The AACE International Class 3 construction capital estimate (Capex) is approximately US$494 million, up from a Class 5 conceptual estimate of US$277 million, reflecting expanded project scope and greater cost certainty. The project now includes 42% higher Dy and Tb separation capacity, three additional separation circuits for Y, Gd, and Sm, and an increase in mixer-settlers from 340 to 478, resulting in approximately 157% more total separated high-purity oxide production. 100% of major equipment packages have been quoted by experienced suppliers, with approximately 86% of equipment packages and 100% of electrical packages expected to be procured in the United States. The operating cost estimate (Opex) has been reduced by approximately 32% to US$26/kg of oxide produced, from US$38/kg at the conceptual stage, excluding SPREC feedstock costs. Based on Capex, Opex, and Argus Media pricing assumptions, the project is estimated to generate an after-tax NPV of US$773 million at an 8.0% discount rate, an after-tax IRR of 27.9%, and a payback period of 2.6 years. The air permit from the Louisiana Department of Environmental Quality was secured in September 2026, representing the principal environmental permitting milestone. Aclara previously announced an estimated US$46.4 million package of incentives, infrastructure support, and workforce development programs from the State of Louisiana, including the Industrial Tax Exemption Program, High Impact Jobs Program, infrastructure support, and LED FastStart®, subject to approvals and performance requirements. Aclara is pursuing a potential long-term financing pathway with the Export-Import Bank of the United States (EXIM), which issued a Letter of Interest on September 4, 2026, indicating willingness to consider financing of up to US$750 million with a repayment tenor of up to 15 years under the Make More in America initiative. The Letter of Interest is non-binding and subject to EXIM's standard due diligence and approval processes. Aclara is progressing toward submission of its formal EXIM financing application. The Virginia Tech demonstration plant is validating the separation process and expanding to include dedicated circuits for Y, Gd, and Sm, with the Y circuit being installed and commissioned and Gd and Sm equipment expected later in Q4 2026. Aclara is also developing an AI-enabled digital twin with Argonne National Laboratory, selected under the U.S. Department of Energy's Genesis Mission, to improve process performance and support scale-up. Project Dynamo is planned for an approximately 82-acre Louisiana Economic Development Certified Site at the Port of Vinton, providing infrastructure and logistics for a large-scale solvent extraction facility and future downstream metals and alloys facility. Next steps include advancing detailed engineering, procurement, site preparation in Q1 2027, submitting the formal EXIM financing application, expanding the Virginia Tech demonstration plant, advancing the AI-enabled digital twin, and continuing customer qualification and partnership discussions.
