Major New US Rare Earths Deposit Confirmed

American Rare Earths Limited's Maiden Drill Program Completed at Halleck Creek Rare Earths Project in Wyoming

Drill at Halleck Creek Rare Earths Project in Wyoming

American Rare Earths Limited (ASX: ARR, OTCQB: ARRNF, FSE: 1BHA) (ARR or 'the Company') is pleased to announce the successful completion of the maiden exploration drill program at the Halleck Creek Rare Earths Project in Albany County, Wyoming. The campaign provided encouraging preliminary data from the exploration target area. ARR drilled 3,008 feet of core samples and collected 822 samples from nine holes in the Red Mountain and Overton Mountain zones, with core recovery exceeding 99%. 


  • Maiden drill program completed
  • High-grade XRF observations ranged >3000 to > 20,000ppm REO
  • Consistent REE enrichment to at least 350 feet
  • Planning for maiden resource drilling underway

There were no safety or environmental incidents over the course of the campaign.

CEO and Managing Director Chris Gibbs commented: "We are extremely excited about what we are seeing at this world-class project as it continues to exceed our expectations. I want to congratulate the entire team who worked enthusiastically and safely to give us the first below surface insights from Halleck Creek."

"Based on the potential size, scale, and grade of this deposit, Halleck Creek may become one of the largest rare earths projects in the US. Since acquiring this asset we have significantly increased the footprint and continue to see high-grade mineralization over a large area."

"We're now looking forward to the lab assay results, expected in late June or July, and based on the preliminary data we're already planning our next phase of work," he continued. 

The Wyoming project contains the full suite of fourteen naturally occurring rare earths mineralization plus notable concentrations of Yttrium, Hafnium, and Zirconium; thus, the deposit could be a source of seventeen minerals deemed "Critical" by the U.S. Government as recently as 2022. 

The completion of the maiden drilling campaign follows 118 surface sample results returned late last month that prompted ARR to stake claims across an additional 2,943 acres. That brings the Halleck Creek Rare Earth Project to over 6051 acres and ARR's total area under exploration across the US to more than 12,900 acres.
