Why it Matters

The Halleck Creek Rare Earths Project: A Wyoming Solution to Diversify and De-Risk the United States’ Upstream Rare Earths Supply Chain

 

Denver, CO – October 17, 2025 – The Trump Administration has made significant and meaningful investments in reshoring the United States’ rare earths industry. However, the rapidly developing U.S. mine-to-magnet industry still has a single point of failure as there is only one domestic rare earths mine currently in production in the United States. Without additional domestic rare earths mines to diversify supply, the growing domestic magnetics industry (incentivized by the US government) remains exposed to supply chain vulnerabilities given the current concentration of global upstream rare earths mining and refining capacity in China.

 

American Rare Earths (“ARR”) (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) (“ARR” or the “Company”)  offers a Wyoming-based solution, the Halleck Creek Rare Earths Project, a mine to magnet project that can diversify, de-risk, and ultimately supply the United States, and its allies, rare earths magnetics industries with the necessary light and heavy rare earths feedstock for the next 100+ years. American Rare Earths applauds the Department of Defense collaboration with MP Materials to construct the 10,000 tonnes per annum Independence Magnetics Facility. However, if the Mountain Pass mine remains the sole domestic supply of mined feedstock, the domestic rare earths market remains at risk. Based on the most recent technical study undertaken by ARR[1], Halleck Creek’s initial base case production could fulfil upwards of 57% of the light rare earths (i.e. Neodymium-Praseodymium or “NdPr”) and 30% of the critical heavy rare earths (i.e Dysprosium, “Dy”, and Terbium, “Tb”) feedstock necessary to supply the Independence Magnetics facility for generations. Halleck Creek is America’s long-term rare earths supply solution.
