American Rare Earths’ northern summer sampling and mapping program has revealed the potential for an even greater, higher-grade rare earth resource in the already significant Halleck Creek deposit in Wyoming.
The news comes as the northern fall drilling program reaches greater depths in the higher-grade Overton Mountain area and the company works toward an updated JORC exploration target.
American Rare Earths (ASX:ARR) had previously focused its attention on the Red Mountain and Overton claims, work that contributed to the 1.43 billion tonne Maiden JORC resource, released in March. Within that there are an estimated 4.73 million tonnes of total rare earth oxides (TREO), of which around 24% are high-value rare earth magnetic elements, essential for the transition to clean energy, the modern communications and national security.
Now, thanks to work completed over the summer, ARR has identified future potential in the areas surrounding the Bluegrass Reservoir, Sommers Flat, Trail Creek and County Line.
Significantly, staff geologists were able to strictly constrain the important boundaries and contacts between the rare earth element (REE)-enriched material and the surrounding rocks.
Additionally, the summer initiative identified areas with greater than 5,000 ppm of TREO.
CEO Donald Swartz commented: “Our summer initiative was successful, as the team has now confirmed the presence of rare earth mineralization over a broader area and at a higher grade than previously known. While more work is needed to confirm the presence of these claims at depth and across the entirety of our properties, we are encouraged by these results as we continue to establish the Halleck Creek property as potentially the largest rare earth mineral deposit in the US. .”
As part of the analysis, 189 surface samples were analyzed by XRF and 52 samples were submitted for confirmatory assay analysis from high-grade target mining areas.
Currently, the company’s geologists are advancing optimization of future drill hole locations, JORC exploration targets, and the location of conceptual mine design and facilities through GPS-confirmed geology.
Delving deeper into Overton
It’s a busy time for ARR as the development drilling program in the Overton Mountain area continues as planned with drills drilling even deeper holes.
One core hole was completed to 305m and exhibited REE mineralization throughout, using XRF. Previous drilling in the area was limited to less than 175m and the deposit is still open at depth.
This week’s announcement closely follows last month’s high-quality trial results of the exciting new Beaver Creek Project, also in Wyoming, plus ARR increased its land ownership in that highly prospective area by 85%.
