American Rare Earths: Advancing One of the Largest REE Deposits in North America


American Rare Earths (ASX:ARR,OTCQX:ARRNF,ADR:AMRRY) unlocks the USA’s rare earths potential through its strategic, high-value asset in Wyoming. The flagship project, Halleck Creek, is one of North America’s largest REE deposits. With a 2.63-billion-ton JORC resource at 3,292 ppm TREO, American Rare Earths is ramping up its development to bolster the North American critical minerals supply chain.

Halleck Creek offers significant exploration upside, presenting a multi-generational opportunity to establish a sustainable rare earths supply chain in the US. The support from EXIM Bank further highlights the strategic importance of Halleck Creek in reducing U.S. dependency on foreign suppliers.

American Rare Earths' project portfolio​Key Projects

The Halleck Creek project in Albany County, Wyoming, is the cornerstone of ARR’s growth strategy. Recognized as one of the largest, rare-earth deposits in North America, it boasts a JORC-compliant resource of 2.63 billion tons at 3,292 ppm TREO. The deposit is hosted in Precambrian granites and metamorphic rocks, which contain REE-enriched minerals like monazite and bastnaesite. The coarse-grained nature of the mineralization ensures cost-effective extraction and processing.

Company Highlights

  • American Rare Earth’s flagship project, Halleck Creek, is one of North America’s largest REE deposits. With a 2.63-billion-ton JORC resource at 3,292 ppm TREO, it holds the potential to meet US rare earths demand for approximately 100 years.
  • The company is completely focused on developing a US-based critical minerals supply chain, aligning with US policies to reduce reliance on China for rare earth supply.
  • The Halleck Creek project’s planned development consists of two phases. Phase 1 entails development of the Cowboy State mine, which is located entirely on Wyoming state land, enabling faster permitting and streamlined regulatory processes. Subsequently, cash flow generated from CSM will support development of the federal portions of Halleck Creek in Phase 2.
  • This phased approach allows ARR to accelerate its pathway to production, enhance shareholder value, and strengthen its position as a key domestic supplier of rare earth elements in the United States.
  • Well-positioned to address critical supply chain vulnerabilities, Halleck Creek benefits from strong federal and state support, including a non-binding EXIM Bank letter of interest for funding up to $456 million.
