The Halleck Creek Rare Earth project in Wyoming, USA, has just undergone exploration drilling, and American Rare Earths Limited has released very encouraging test findings. These initial findings come from four of the nine holes that were done at Halleck Creek. Assay analysis is still ongoing for the remaining five holes, but results should be available soon.

The Company took 650 core samples while drilling nine holes totaling 917 m between March and April 2022. The test findings from 280 samples from four core holes show that the Red Mountain Pluton’s (RMP) clinopyroxene quartz monzonite (CQM) rocks are consistently associated with rare earth mineralization.
The business will expedite its exploration efforts to establish a first JORC resource at Halleck Creek due to these encouraging assay results. This exploration program’s planning is well underway, and the business will inform the market as soon as drilling licenses are issued.
This project continues to deliver well beyond our expectations.

The first purchase was a little parcel of property that had some unique surface information. Since then, scientists have grown the landholding to more than 6000 acres. As these drill assay results support the substantial field surface sample work done, American Rare Earths is starting to comprehend the vast scale of this deposit.
“The sheer size and consistently higher grades of this deposit are extremely exciting. The low Thorium content will also set this deposit apart from others in the rare earths industry. Our next objectives for this project are to upgrade the Exploration Target and fast track establishing a significant JORC resource with our next drill campaign.”
Assay Results
Initial assay results for four holes (HC22-RM01, HC22-RM02, HC22-RM03, HC22-RM04) show favorable and reliable levels of rare earth element (REE) enhancement.
Core holes HC22-RM01, HC22-RM02, and HC22-RM03 comprise an average TREO value of 4,252 using a cut-off of TREO 1,500 ppm. Each of these core holes has more than TREO 3,500 ppm of rare earth mineralization. As a result, the deposit is still exposed at depth.
It is noteworthy that the mineralization observed by TREO at these enormous thicknesses is both of greater grade and deeper than that predicted by the Halleck Creek Exploration Target. The company plans to increase the current Exploration Target if present trends persist in the final core drilling results.
Next Steps
In July 2022, more drilling data from the project should be revealed. The following phases entail revising the current Exploration Target and creating a more thorough drilling program to define a high tonnage first JORC resource. If the project succeeds, it might develop into a significant rare earth mine that supplies the US defense sector and the supply chains for renewable energy.
