Halleck Creek is positioning itself to be one of the largest rare earth projects in the United States and a key asset for the domestic supply chain
- Total JORC Resource of 1.43 billion tonnes
- Estimated 4.73 million tonnes of contained Total Rare Earth Oxides (TREO) in-situ
- Mineralization contains approximately 24% highly valuable magnetic rare earth elements
- TREO average grade of 3,309 ppm
- Significant upside potential with 75% of district yet to be drilled and deposit remaining open at depth
- Deposit is from surface to at least 150 meters with consistent grades throughout making it ideal for large scale, low-cost open pit mining
- Environmentally friendly with low levels of penalty thorium and uranium elements
March 31, 2023 (Source) – The Board of American Rare Earths (ASX: ARR | OTCQB: ARRNF | FSE: 1BHA) the ‘Company’ is pleased to announce a maiden JORC Resource estimate for its Halleck Creek Rare Earths Project ‘Halleck Creek’ in Wyoming, USA. The JORC Resource at Halleck Creek is 1.43 billion tonnes with an average TREO grade of 3,309 ppm, and an average NdPr grade of 734 ppm. The JORC Resource estimate has exceeded expectations in comparison to previous exploration target estimates and has demonstrated the Halleck Creek project has the potential to become a world class deposit. The resource area covers 949 acres of the total exploration area held by the Company which totals 8,165 acres, meaning the JORC Resource has the potential to greatly increase with future exploration campaigns.
Chief Executive Officer and Managing Director Chris Gibbs said: “These results confirm the Company has a strategically significant rare earth asset, in the United States, which should enable the largest economy in the world to reduce its dependence on China or other imported rare earths.
“Global magnetic rare earth oxide consumption is forecast to more than triple by 2035. The US government has made no secret that it is seeking to onshore supply of all critical materials for supply chain and national security purposes. There is only one producing rare earth mine within the USA, the Mountain Pass mine in California. The USA needs a number of these mines to secure onshore supply of rare earths and we believe Halleck Creek is part of the future solution.
“With a maiden JORC Resource estimate of 1.43 billion tonnes this project is strategically significant, containing over 4.73 million tonnes of rare earth oxides. With only a quarter of the licence area drilled and remaining open at depth, the upside potential is significant. The Halleck Creek project is shaping up to be a strategic asset for the USA to supply rare earths for future generations”.

Under the supervision of Wood PLC, one of the world’s leading consulting and engineering companies, metallurgical test work is ongoing to optimize the process flow sheet. This includes bulk WHIMS and floatation test work which are well advanced, to assess the likely constituents of an upgraded concentrate product. Testing will commence immediately thereafter on the further upgrade of the concentrates via a leaching process. The metallurgical test work will provide the foundation for the Scoping Study scheduled for later this year. Additional exploration and development work also continues at Halleck Creek.
“This is an excellent outcome from our drilling program and a key step towards creating significant shareholder value. We are committed to growing our rare earth resources and developing our operations in the USA.
“This market announcement has been authorized for release to the market by the Board of American Rare Earths Limited.”
