Core Insights - American Rare Earths has released a preliminary updated mineral processing flowsheet for the Halleck Creek Rare Earths Project, marking a significant milestone towards establishing the next producing rare earths mine in the United States [1][4][28] Mineral Processing Flowsheet - The updated flowsheet incorporates recent hydrometallurgical test results, indicating progress in optimizing the mineral processing methods [4][12] - The ongoing optimization work is expected to enhance the recovery of rare earth elements (REEs) from the ore, with preliminary results showing promising outcomes [3][12] Beneficiation Optimization - Preliminary Reflux Classifier Concentrator (RCC) tests suggest a more efficient alternative to spirals as the primary beneficiation method, achieving a mass yield of 14.0% and a TREO recovery of 78.4% [5][15] - The RCC method demonstrated a 44% decrease in mass yield compared to spirals, with a significantly higher enrichment factor of 5.66 [17] Comminution Tests - Ongoing comminution optimization tests aim to reduce fines generated during ore processing, which could positively impact both beneficiation processing and overall REE recoveries [3][6][12] - The company is testing multiple conventional milling methods to optimize the front-end process [6][11] Future Steps - A bulk sample of Halleck Creek ore will be processed through the entire preliminary updated flowsheet, excluding the separation and finishing step, to complete the necessary datasets for the forthcoming Pre-Feasibility Study (PFS) [10][12] - The results from the ongoing optimization tests are expected to further validate the technical and economic viability of the Halleck Creek project [12][29]

Core Viewpoint - American Rare Earths is advancing its Halleck Creek Rare Earths Project in Wyoming, focusing on optimizing mineral processing for the Cowboy State Mine as part of its Pre-Feasibility Study (PFS) [2][5]. Project Activities - The company will conduct additional mineral processing optimization tests, including various comminution methods and beneficiation circuit optimizations [3][6]. - Long-lead time equipment for a demonstration plant has been ordered, and test mining will begin shortly to provide necessary feedstock [4][9]. Importance of PFS - A PFS is crucial for demonstrating the technical and economic viability of the project, providing confidence to potential investors and partners [5][6]. - The PFS serves as a blueprint for the mine and processing plant, laying the groundwork for future studies that could lead to construction decisions [5][7]. Optimization Work Summary - Ongoing mineral processing optimization tests aim to enhance the recovery of rare earth minerals [9]. - Test mining will yield approximately 3,200 tonnes of material to support both optimization tests and future demonstration plant needs [10]. Comminution and Beneficiation - The optimization testing focuses on reducing fines in the ore to improve overall concentration and reduce operational costs [10][15]. - The company plans to utilize Induced Roll Magnetic Separators for effective separation of rare earth minerals from gangue material [15]. Strategic Positioning - The Halleck Creek Project is positioned to reduce U.S. reliance on rare earth imports, particularly from China, while addressing the growing demand for these critical minerals [14]. - The project emphasizes environmentally responsible mining practices and collaboration with U.S. government-supported R&D programs [14].
