American Rare Earths Ltd (ASX:ARR, OTCQB:ARRNF) earlier this week provided an update on its Halleck Creek project, revealing high-grade assay results from its recent drilling program.
The company said the latest results exceeded 5,000 parts per million of rare earth oxides in the western section of the deposit. One intercept measured 148 meters at 4,451 parts per million, including 52 meters at 5,273 parts per million. Another notable finding was 161 meters at 4,275 parts per million.
CEO Chris Gibbs explained that these results build on the deposit’s consistent mineralization and highlighted that surface samples extend at depth, with drilling confirming the deposit continues down to 300 meters.
The company said earlier scoping studies demonstrated robust project economics, and these results will form part of the pre-feasibility study scheduled for 2024. The Halleck Creek resource is estimated at 2.34 billion tons, making it one of the largest rare earth deposits in North America.
Gibbs emphasized the deposit’s strategic importance, stating it could supply the U.S. domestic market for over 100 years. With the U.S. reliant on China for rare earth imports, the project represents a critical step in securing domestic supply chains.
Permitting is underway, and the company expects approvals to take less than two years. American Rare Earths is also collaborating with BMO Capital Markets (NYSE:BMO) to advance the project.
