American Rare Earths Appoints New Auditor and Targets Nasdaq Listing by 2026 American Rare Earths has appointed BDO Audit Pty Ltd as its new auditor.
The company has begun work on a planned Nasdaq listing, targeted for completion later in 2026.
ARR aims to achieve a Nasdaq compliance listing without raising new capital, while keeping the ASX as its primary listing venue.
A move toward a dual listing on Nasdaq aligns the company more closely with U.S. capital markets and may broaden its potential investor base and liquidity profile over time.
Relying on a compliance listing without fresh capital means you should pay close attention to how the company manages its existing funding, project spending and any future disclosure around listing requirements. Announcement • Apr 08
American Rare Earths Awards Whole of Property Development Assessment for Halleck Creek American Rare Earths awarded a Whole of Property Development Assessment for its flagship Halleck Creek rare earths project in Wyoming to a major engineering firm, with work scheduled to commence in Second Quarter 2026. The Whole of Property Development Assessment is a planning level, desktop study that will integrate all existing geological, metallurgical, mining and permitting data across American Rare Earths’ entire 8,108-acre Halleck Creek land package in Albany and Platte Counties, Wyoming. The assessment will build on the Phase 1 Cowboy State Mine plan and establish a strategic roadmap for subsequent expansion phases at Red Mountain, Overton Mountain and Bluegrass. Halleck Creek hosts a total in-situ mineral resource estimate of approximately 2.63 billion tonnes of ore, providing scope for long term, multi-generational potential production under current scoping level development assumptions. The Cowboy State Mine alone has an estimated mine life of 20 years and very low strip ratio of 0.383. The Whole of Property Development Assessment is designed to fully leverage this combination of scale and jurisdictional advantage by optimizing how the broader Halleck Creek district is developed over time. The Whole of Property Development Assessment will synthesize existing geological, metallurgical and economic data from the Cowboy State Mine, Red Mountain, Overton Mountain and Bluegrass areas into a unified project-wide model. The Whole of Property Development Assessment will compare resource areas on grade, strip ratio, resource confidence, metallurgical characteristics and infrastructure proximity to determine which zones should be prioritized in future phases. The Whole of Property Development Assessment will develop conceptual mine plans and expansion scenarios at 5–10 million tonnes per annum, assessing mine-life extension options and cumulative resource utilization across the entire property. The Whole of Property Development Assessment will map out permitting pathways and land-status considerations for Bureau of Land Management lands. By integrating these workstreams, the Whole of Property Development Assessment will give American Rare Earths a clearer view of how to sequence development of the largest known deposit of total contained rare earth oxides in North America, and how to scale production from a state-permitted Wyoming base toward multi-phase district development in response to United States demand and policy support. The Whole of Property Development Assessment directly supports this strategy by providing the potential technical and economic basis to extend the Cowboy State Mine into a much larger multi-phase operation across state and federal lands, consistent with the Company’s ambition to secure United States critical mineral independence for generations. The Whole of Property Development Assessment will inform long-term capital planning and help prioritize investments that enhance scale, optionality and returns. The Whole of Property Development Assessment will support engagement with state and federal stakeholders by clearly articulating how Halleck Creek can be expanded in a responsible, staged manner from its Wyoming base to meet growing United States defense and technology demand. The Whole of Property Development Assessment follows American Rare Earths’ December 2025 technical breakthrough, in which the updated preliminary Pre-Feasibility Study flowsheet successfully produced rare earth oxides from Halleck Creek ore. Using the refined mineral processing flowsheet, the Company produced both a mixed rare earth oxalate and a mixed rare earth oxide from purified leachate solution after impurity removal, demonstrating a clear path from ore to saleable rare earth products. That breakthrough provides the processing assumptions and recovery parameters that will underpin the Whole of Property Development Assessment’s analysis of future phases across Red Mountain, Overton Mountain and Bluegrass. The Whole of Property Development Assessment is expected to run through to the end of 2026, with key milestones including data compilation and verification, integrated geological synthesis, resource-area comparison, mine-planning scenarios and development sequencing. American Rare Earths has some 8.64 million tonnes of contained Total Rare Earth Oxide and is advancing its strategy to become a cornerstone of the United States rare earths supply chain.
