American Rare Earths Accelerates Halleck Creek Pilot Plant and NASDAQ Listing Plans

Pilot Plant Pathway Shortens Halleck Creek Timelines

American Rare Earths Limited (ASX:ARR) has significantly accelerated the development of its flagship Halleck Creek Rare Earths Project in Wyoming, pivoting toward integration within the U.S. domestic rare earth mine-to-magnet supply chain. Central to this push is a newly defined pilot plant pathway that combines front-end mineral processing in Wyoming with downstream hydrometallurgical refining and oxide separation in Canada’s Saskatchewan Research Council. This hybrid approach is expected to produce pre-production rare earth oxide within months, a material step forward from earlier technical milestones.

This move builds on the company’s recent success in producing mixed rare earth oxides from Halleck Creek ore, a breakthrough that validated its updated processing flowsheet and resource estimate, as detailed in its January 2026 update. The pilot plant program is designed to de-risk execution and provide samples suitable for downstream qualification, positioning Halleck Creek as a cornerstone asset in U.S. supply chains.

Advancing Downstream Processing and District Development

In parallel, American Rare Earths has engaged Tetra Tech to conduct an oxide to metal study focused on heavy rare earth elements such as samarium, gadolinium, terbium, and dysprosium. This study aims to assess technologies like molten salt electrolysis and calciothermic reduction to convert rare earth oxides into metals, a crucial step immediately preceding permanent magnet manufacturing. The work will develop process flow diagrams and equipment requirements, helping bridge the gap between oxide production and magnet manufacturing within North America.

Complementing these technical efforts, the company awarded a Whole of Property Development Assessment to a major engineering firm. This district-wide study will integrate geological, mining, metallurgical, and permitting data across the broader Halleck Creek land package, supporting long-term development sequencing and expansion scenarios beyond the Wyoming state-permitted core.

Leadership Strengthened to Support Execution

American Rare Earths has consolidated the CEO and President roles under Mark Wall, aiming to sharpen strategic alignment and accelerate decision-making. The company also appointed Nick Lissolo as Vice President of Corporate Development and Strategy, bringing extensive experience from Newmont Corporation and local Wyoming ties. Additional key hires include Jaye T. Pickarts as Pilot Plant Lead and Lucas Hekma overseeing permitting, both veterans in their fields, alongside Brook Brockman directing public and government affairs to foster community and regulatory engagement.

Financial Position and NASDAQ Listing Progress

Financially, American Rare Earths maintains a robust cash position of A$24.8 million as of 31 March 2026, underpinned by disciplined capital management, including proceeds from a recent sale of its stake in Godolphin Resources and option exercises. The company reported modest net cash outflows for operating and project development costs during the quarter, supported by a Wyoming Energy Authority grant.

Meanwhile, work to list on NASDAQ is advancing with completion targeted by the end of 2026, aiming to enhance access to U.S. capital markets and investor visibility. This aligns with the company’s broader strategy to position Halleck Creek as a U.S.-based, long-life source of magnet rare earths critical to national security and advanced technologies.

Exploration and Government Engagement

Beyond Halleck Creek, American Rare Earths has initiated an AI-supported technical review of its La Paz Project in Arizona, evaluating potential for gold, silver, copper, manganese, and rare earth mineralisation. This comprehensive assessment aims to identify new exploration targets and inform future programs.

The company continues proactive engagement with U.S. government departments in Washington, D.C., contributing to emerging critical minerals and rare earths policy initiatives. These include efforts to expedite permitting, leverage Defense Production Act tools, and secure financing to bolster domestic supply chains. The company’s collaboration with research institutions and participation in the U.S. Department of Energy’s METALLIC consortium further embed Halleck Creek within national strategic frameworks.

With the Pre-Feasibility Study progressing toward completion in late Q3 2026, American Rare Earths is clearly transitioning from evaluation to execution, cementing its role as a strategic player in U.S. critical minerals supply chains.
