American Rare Earths Limited (ASX:ARR) has unveiled highly promising assay results from recent exploration drilling in the Halleck Creek Rare Earth project in Wyoming, USA.
These preliminary results are from four of nine holes drilled at Halleck Creek. Results for the remaining five holes are pending assay analysis and expected soon.
During the period from March to April 2022 the company drilled nine holes for 917 metres and collected 650 core samples. The assay results (from 280 samples) taken from four core holes demonstrate consistent rare earth mineralisation associated with clinopyroxene quartz monzonite (CQM) rocks of the Red Mountain Pluton (RMP).
MD and CEO Chris Gibbs said that due to these promising assay results the company will accelerate its exploration plans to define a maiden JORC resource at Halleck Creek.
Planning is well underway for this exploration programme.
“This project continues to deliver way beyond our expectations. The initial acquisition was a tiny land package with some interesting surface data,” Mr Gibbs said.
“We have since increased the land holding to over 6000 acres and now beginning to understand the massive nature of this deposit as these drill assay results confirm our extensive field sample work. The sheer size, scale and consistent high grade of this deposit is extremely exciting.
“The low Thorium and Uranium elements will also set this deposit apart from others in the rare earths industry. Our focus is to upgrade the Exploration Target for this project, fast track our drilling efforts and establish a significant JORC resource as soon as reasonably practicable.”
Assay Results
Preliminary assay results for four holes (HC22-RM01, HC22-RM02, HC22-RM03, HC22-RM04) indicate promising and consistent levels of rare earth element (REE) enrichment. These four holes are the first reported from the maiden drilling program at the Halleck Creek Rare Earth Project. All four diamond core drill holes are at the Red Mountain resource area located within the greater Halleck Creek Project Area in, Albany County, WY.
Therefore, the Exploration Target of approximately 308 to 385 million tonnes of rare earths mineralised rocks with an average TREO grade of 2,330 – 2,912 ppm may have been significantly underestimated.
The company intends to expand current exploration target once all assay results are received. Readers are advised that the potential quantity and grade of the Halleck Creek resource is conceptual in nature, that there has been insufficient exploration to estimate a Mineral Resource and that it is uncertain if further exploration will result in the estimation of a Mineral Resource
Drilling shows consistent high-grade mineralisation from surface and remains open at depth. Significant intercepts include:
o HC22-RM01 averages 4,115 ppm TREO over 98.6 m
o HC22-RM02 averages 4,335 ppm TREO over 94.6
o HC22-RM03 averages 4,317 ppm TREO over 93.8 m.
