Highlights
- 15 RC holes each drilled to 102 m for a total of 1,530 m.
- Assay results confirm higher-grade rare earth mineralization from surface, remaining open at depth:
- Average TREO grade increased 26% to 4,179 ppm for the entire exploration program.
- Highest grade assay of 11,040 ppm TREO.
- Numerous holes exhibit grades exceeding 1500 ppm TREO along nearly their entire 102 m length, including;
- HC23-OM044: 102 m @ 5472 ppm TREO
- HC23-OM038: 100.5 m @ 4493 ppm TREO
- HC23-OM033: 102 m @ 4291 ppm TREO
- HC23-OM042: 100.5 m @ 4281 ppm TREO
- Neodymium and Praseodymium (NdPr) distribution continues at 23%.
- Resource modeling update is currently underway with significant upgrade to JORC resource estimates expected in the coming months.
DENVER, Dec. 14, 2023 (GLOBE NEWSWIRE) — American Rare Earths Limited (ASX: ARR | ADRs – OTCQX: AMRRY | Common Shares – OTCQB: ARRNF) (“ARR” or the “Company”) is pleased to announce continued exceptional drilling results from its October-November 2023 drilling campaign1,2 at Overton Mountain, located within the broader Halleck Creek Rare Earths project area. See Figure 1. Of the fifteen-reverse circulation (RC) holes drilled, there was an average TREO value 24% higher than that of the Company’s previous JORC resource estimate3 (3,309 ppm TREO). Nine of the fifteen RC holes exhibit an average TREO value of greater than 4,000 ppm, utilizing a cutoff value of 1,500 ppm. The addition of the final RC assays will be a significant contribution to upgrading the Company’s current 1.43 billion tonne JORC resource. The fence diagrams presented herein illustrate the homogenous nature of the deposit which lends itself to low-cost, near-zero strip ratio mining operations. See Figure 2.
CEO Donald Swartz commented on the results:
“Exceptional results from the recent resource upgrade drilling campaign at the Halleck Creek Resource Area have not only surpassed our expectations, but are expected to exceed our previous resource estimates. The average TREO values of the RC holes, especially HC23-OM044’s outstanding intercept, demonstrate the potential of this project.”
“These results along with the recently announced diamond drilling results provide us confidence to be able to provide shareholders with a significant upgrade to our JORC resource estimates, which is expected in Q1 2024.”

Extract from Technical Summary
Since the announcements on November 1, 2023 and December 7, 2023, assays for all fifteen RC holes drilled at the Overton Mountain resource area have been received. The drill holes were spaced between 50 and 75 meters apart showing vertical and lateral continuity across the exploration area. Major intercepts from RC assays reinforce excellent results produced from diamond core. ARR is confident that a significant measured resource will be achieved.
HC23-OM044 is the most impressive RC hole, exhibiting the best intercept observed at the Halleck Creek to date.
- HC23-OM044 averages 4,207 ppm TREO over 57.00 m; averages 8,364 ppm TREO over 31.50 m.
Average NdPr comprises 23% of TREO from all fifteen RC holes, consistent with previously announced diamond core results. Penalty elements remain de minimis, with an average thorium concentration of 69 ppm, and an average uranium oxide concentration of 7 ppm.
This announcement has been approved by the CEO of American Rare Earths.
