American Rare Earths and University of Wyoming will evaluate technical and commercial uses for tailings to boost Halleck Creek economics.
American Rare Earths Ltd (ASX:ARR, OTCQB:ARRNF) has joined with the University of Wyoming to evaluate potential end-uses for tailings and other byproducts from its Halleck Creek rare earths project.
Selected for a competitive Seed Translational Acceleration of Research (STAR) award under UW’s NSF-backed Accelerating Research Translation (ART) program, the one-year collaboration will assess technical and economic viability of secondary material streams with the aim of improving project economics and reducing environmental footprint.
Researchers from UW’s School of Energy Resources, led by Tyler Brown at the Center for Economic Geology Research, will work directly with Wyoming Rare (USA) Inc., American Rare Earths’ US subsidiary. Planned deliverables include a comprehensive material-properties database, computational modelling to screen commercial applications, and small-scale laboratory validation of high-potential uses.
Results will inform processing requirements and how any viable byproducts could be integrated into Halleck Creek’s development pathway. Halleck Creek, on Wyoming state land, is being advanced as a long-life open-pit operation with onsite processing and separation. The STAR award is part of a broader ART initiative backed by US government funding to accelerate commercial outcomes in energy and critical minerals, reinforcing domestic supply-chain and responsible-mining goals.
American Rare Earths Limited (ASX: ARR) is a Sydney-based mineral exploration and development company focused on advancing large-scale rare earth projects in the United States to establish a secure, domestic supply chain for critical minerals.
