American Rare Earths Limited (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) ("ARR" or "the Company") is pleased to announce the successful completion of the extended 2024 drilling program at its Halleck Creek Rare Earths Project in Albany County, Wyoming. As part of the program extension, five additional reverse circulation (RC) drill holes were completed, totalling 837 meters (2,746 feet), focused on the western section of the Cowboy State Mine (CSM) deposit. This area was previously identified as having higher-grade rare earth mineralization.

Key Highlights:

• Five additional RC drill holes were successfully completed in the western area of the CSM deposit, known for higher-grade mineralization.
• Geophysical logging and detailed geological analysis of the drill cuttings are underway.
• Samples have been dispatched to ALS Global for formal assay, with results anticipated in the near future.

The extension to the 2024 drilling program, as announced earlier, targeted high-potential zones within the western portion of the deposit, particularly near Red Mountain, where higher grades have been confirmed. The completion of these additional holes contributes critical data that will support ongoing resource model updates and the long-term development of the project.

Chief Executive Officer, Chris Gibbs commented:

"The completion of these additional drill holes marks an important step forward in our exploration efforts at Halleck Creek. By targeting the western area of the CSM deposit, we are focused on high-grade zones that can significantly enhance the project’s resource potential. We are excited about the next phase of analysis and eagerly await the formal assay results, which will provide valuable data to upgrade our resource models and mine plans. With each stage, we are building a solid foundation for the future of Halleck Creek."

Next Steps

As the geophysical logging and sample analysis progress, ARR’s team will incorporate the data into updated geological models. We are looking forward to receiving the assay results, which will play a crucial role in resource estimation and future planning. ARR will continue to keep the market informed as the program advances.
