American Rare Stock Price, News & Analysis

American Rare Earths (OTCQX: AMRRY) has initiated test mining operations at its Cowboy State Mine, part of the Halleck Creek deposit in Wyoming. The company successfully completed its first blast, targeting the extraction of 3,200 tonnes of ore to serve as feedstock for a demonstration plant.

The mining process involves two phases: first, extracting weathered material from 3.6 meters below surface, followed by accessing and crushing underlying non-weathered ore to approximately 5-centimeter pieces. The extracted material will support metallurgical testing, process optimization, demonstration plant operations, and sample production for potential offtake partners.

This milestone represents a crucial step in de-risking full-scale development, validating processing flowsheets, and refining engineering and cost models for future plant construction.

American Rare Earths (OTCQX: AMRRY) announced a significant breakthrough in rare earth element (REE) processing at its Halleck Creek project. The SynBREE consortium, led by Lawrence Livermore National Lab, successfully produced 97.1% pure Heavy Rare Earth Oxide (HREO) and 96.4% pure Light Rare Earth Oxide (LREO) concentrates from the project's allanite-based ore.

The achievement is part of the US Department of Defense's DARPA EMBER project, which aims to develop biotechnology-based REE separation and purification strategies. The University of Kentucky processed approximately 840kg of ore from 36 drill holes, achieving an 82% recovery rate of total rare earths from the leachate solution.

American Rare Earths (AMRRY) has secured A$15.0 million through a private placement at A$0.32 per share, representing an 18.8% discount to the 10-day VWAP. The placement received strong support from existing shareholders and institutional investors globally.

The funds will be strategically allocated to accelerate the development of the Halleck Creek Rare Earths Project in Wyoming, one of the largest rare earth deposits in the U.S. Specifically, the proceeds will fund a demonstration plant for the beneficiation process, in-fill drilling at the Cowboy State Mine, and engineering work.

American Rare Earths (OTCQX: AMRRY) has announced significant progress in optimizing mineral processing at its Halleck Creek Rare Earths Project's Cowboy State Mine in Wyoming. The company is conducting parallel mineral processing optimization tests focused on improving magnet rare earths recoveries through multiple comminution and beneficiation methods.

Key developments include ordering long-lead time equipment for a demonstration plant, including conventional magnetic separation equipment, and plans to commence test mining to extract ~3,200 tonnes of bulk samples. The optimization work involves testing three different comminution methods: Vertical Roller Mill, High Pressure Grinding Rolls Air Classifier, and HPGR Tower Mill.

While this additional optimization work will extend the Pre-Feasibility Study (PFS) timeline, it aims to create a more robust mineral processing flow-sheet and advance the project toward becoming a producing asset.

American Rare Earths (AMRRY) has announced significant progress in its Halleck Creek Rare Earths Project's metallurgical testing program. The company achieved notable leach recoveries for critical rare earth elements, including 85% for Praseodymium and 84% for Neodymium at optimal conditions.

The testing, conducted at SGS's laboratory in Lakefield, included 25 leach tests exploring various parameters. A key breakthrough was achieved with significantly lower impurity elements, with iron and aluminum concentrations 5.0x and 2.9x lower respectively compared to previous Scoping Study tests. The company has selected Atmospheric Tank Leach as the preferred method, noting its superior energy efficiency and cost-effectiveness.

These results represent a crucial milestone in the technical de-risking of the Cowboy State Mine Pre-Feasibility Study, establishing optimal leach conditions for producing rare earth magnet oxides.

American Rare Earths (AMRRY) has achieved a significant milestone in its permitting process for the Cowboy State Mine project by successfully installing 10 groundwater monitoring wells. The wells, part of the Halleck Creek Rare Earths Project in Wyoming, will collect baseline environmental and hydrological data over a 12-month period to support the state mining permit application with the Wyoming Department of Environmental Quality (WDEQ).

The project, located on State-managed land, benefits from a streamlined permitting process compared to Federal lands. The company plans to conduct 24-hour pump testing to measure water flow and assess mine dewatering requirements. The Pre-Feasibility Study (PFS) remains on track for completion in late 2025, with first production targeted for 2029. The project is supported by a substantial 2.63 billion tonne JORC Resource, positioning it as one of the largest rare earth projects in the United States.

American Rare Earths (AMRRY) has reported promising results from its channel sampling program at the Cowboy State Mine, part of the Halleck Creek Rare Earths Project in Wyoming. The program revealed Total Rare Earth Oxide (TREO) grades up to 13,651 ppm (1.37%), with 15 of 106 samples exceeding 4,500 ppm TREO.

Key findings include magnet rare earth oxides (MREO) averaging 1,023 ppm (28% of total TREO) and heavy rare earth oxides (HREO) averaging 464 ppm (13% of TREO). The southern portion of Red Mountain showed the highest-grade material. The company's Pre-Feasibility Study remains on track for completion in late 2025, with potential first production by 2029.

Located on state lands in Wyoming, the project benefits from streamlined development pathways and could become a significant domestic source of critical rare earth materials, particularly terbium and dysprosium, which are crucial for high-temperature magnet performance and currently face export restrictions from China.

American Rare Earths (AMRRY) has announced two key leadership appointments effective May 5, 2025. Brian Arkell joins as Non-Executive Director, bringing over 35 years of experience in mineral exploration and mine development. His expertise includes developing major gold and copper-gold projects across the Americas and Southeast Asia, with previous roles at Argonaut Gold, Caza Gold Corp, and Newmont Mining Corporation. Megan McPherson has been appointed as Chief Financial Officer, bringing 23 years of experience in finance and governance, including CFO and Company Secretary roles at ASX-listed mining companies. These strategic appointments aim to strengthen the company's leadership team as it advances its U.S.-based rare earths strategy, particularly at Halleck Creek.

American Rare Earths (ARRNF) has announced results from its Updated Halleck Creek Scoping Study, revealing strong economic potential for its rare earths project in Wyoming. The study presents two development scenarios:

The 3 Mtpa base case shows:

• NPV10% of US$558M with 24% IRR
• CAPEX of US$456M with 2.7-year payback
• Annual production of 4,169 metric tons TREO, including 1,833 tons NdPr oxide

The 6 Mtpa case demonstrates:

• NPV10% of US$1.17B with 28.4% IRR
• CAPEX of US$737M with 1.8-year payback
• Annual production of 7,661 metric tons TREO, including 3,344 tons NdPr oxide

The project benefits from state land tenure for accelerated permitting and covers only 16% of the total project area, with significant expansion potential. First production could begin by 2029.
