Unlocking Rare Earth Potential: Halleck Creek Advances Research
American Rare Earths Hits Milestone with Halleck Creek Project
Recently, American Rare Earths Limited (NASDAQ: ARR | OTCQX: ARRNF | ADR: AMRRY) made significant strides in unlocking the potential of its Halleck Creek Rare Earths Project. This project is centered around the Cowboy State Mine, where detailed leach testing has revealed impressive recovery rates for valuable rare earth elements.
Outstanding Leach Recoveries Achieved
The results from the leach tests showcased remarkable recoveries. Praseodymium (Pr) achieved a recovery rate of 85%, while Neodymium (Nd) followed closely with 84%. These high recoveries indicate efficient extraction processes that can significantly enhance the project's economic viability.
Recovery Rates for Heavy Rare Earths
Moreover, the testing also reported encouraging results for heavy rare earth elements. For instance, Terbium (Tb) recovery was recorded at 52% and Dysprosium (Dy) at 46%. This performance position's Halleck Creek among competitive projects in the industry, making it an attractive destination for investors.
Reduced Impurities Highlight Processing Advancements
One of the standout achievements from the leach testing program is the remarkably low levels of impurity elements post-leach. Concentrations of iron and aluminum were noted to be around 5.0 times and 2.9 times lower, respectively, than prior tests conducted for the Scoping Study. This reduction in impurities paves the way for cleaner production processes, which is a step forward in producing rare earth magnet oxides efficiently.
Cost-Effective Leaching Method
American Rare Earths has opted for atmospheric tank leaching as the preferred method due to its energy efficiency and cost-effectiveness compared to traditional techniques like acid-baking. This innovative approach is expected to streamline production costs and enhance overall project feasibility.
Development of Metallurgical Tests
The success of these leach tests is instrumental for the ongoing metallurgical testing phase and the overall flow-sheet development for the Pre-Feasibility Study (PFS). American Rare Earths undertook 25 leach tests at SGS’s laboratory in Ontario, Canada, exploring a variety of parameters and methods.
Scoping Tests and Future Steps
Following these remarkable initial results, the next step involves impurity removal tests at SGS. These tests will lay the groundwork for constructing a robust mineral processing flow-sheet that aligns with industry standards.
Significance of the Halleck Creek Project
The Halleck Creek Project is shaping up to be a significant player in the U.S. rare earths industry, particularly in light of increasing demand for rare earth elements crucial for defense, technology, and economic security. The Cowboy State Mine benefits from open-pit mining methods, which ensures operational efficiency and facilitates streamlined permitting processes in a favorable regulatory environment.
As the project advances, its potential to bolster America's critical mineral independence cannot be overstated. American Rare Earths is dedicated to environmental responsibility during mining operations and collaborates with various U.S. Government-supported R&D initiatives to refine extraction and processing technologies further.
Future Outlook
With ongoing exploration and testing, Halleck Creek is positioned to transform the U.S. supply chain for rare earth elements. This project's success is backed by a commitment to innovate and meet the rising demand for rare earths that are pivotal for modern technologies.
