American Rare Stock Price, News & Analysis

American Rare Earths (ADR: AMRRY) released preliminary updated mineral processing flowsheet and initial beneficiation optimization results for the Halleck Creek rare earths project on Nov 10, 2025. Preliminary Reflux Classifier Concentrator (RCC) tests on coarse and fine fractions produced a 14.0% mass yield, 78.4% TREO recovery and a 5.66x enrichment. ARR reports the RCC yield is ~11 percentage points lower than spirals (a 44% mass-yield reduction) and a 126% higher enrichment factor versus spirals. Bulk RCC testing using comminution-optimised feed and further oxalate/oxide work are planned as gating items before the PFS datasets are finalised.

American Rare Earths (ADR: AMRRY) announced board changes effective October 28, 2025: Jason Beckton was appointed as Non-Executive Director and Hugh Keller resigned as Non-Executive Director.

Mr. Beckton is a professional geologist with more than 30 years’ experience, a BSc (Hons) and Master of Economic Geology, and recent rare-earths work in Finland developing carbonatite-hosted mineralization. His background includes roles at Pancontinental, Goldfields, Gympie Gold, Palmarejo (project manager) and leading the team for the 2007 commercial discovery of Caspiche. The Board said Beckton’s technical expertise will support advancement of the Halleck Creek Project toward demonstration and pre-feasibility stages.

American Rare Earths (ADR: AMRRY) reported quarterly activity for the period ending September 30, 2025 outlining technical, permitting and funding progress at the Halleck Creek Rare Earths Project in Wyoming.

Key technical milestones include an impurity-removal breakthrough with minimal gypsum and silica gel formation, high light-rare-earth leach recoveries (Nd 84%, Pr 85%), completed test mining of 3,080 tonnes, and ongoing optimization for a beneficiation demonstration plant. Corporate highlights: A$15.0m placement at A$0.32, A$1.465m from option exercises, A$21.2m cash at quarter end, and ~A$8.8m available under a Wyoming matching grant. Permitting and PFS work will continue into 2026.

American Rare Earths (ADR: AMRRY) announced completion of the first phase of impurity removal neutralization tests for Halleck Creek allanite ore on October 13, 2025. SGS Lakefield testing found MgO optimal for primary neutralization, producing minimal gypsum and silica gel. Key results: 99.8% iron, 99.4% titanium, 92.9% thorium removal in primary neutralization (PN12) with average REE loss of 0.6% LREE and 0.8% HREE. Secondary neutralization (SN2) removed further impurities but precipitated 7.6% LREE and 16.7% HREE, with solids recommended to be recycled to leaching. Data will feed the PFS flowsheet and remaining hydrometallurgical work is expected to finish before year-end.

American Rare Earths (OTCQX: AMRRY) has completed a significant test mining operation at its Cowboy State Mine within the Halleck Creek deposit. The company successfully excavated and crushed approximately 3,080 tonnes of rare earth ore, with 13.7 tonnes dispatched to various vendors for comminution testing and process optimization.

The testing program, involving partners like Fl Smidth, Loesche GmbH, Corem, and DISA Technologies, aims to optimize milling methods to minimize fines generation and enhance rare earth recoveries. The remaining ore will be stockpiled for use in a future demonstration plant, which will validate processing methods and support technical studies.

This initiative is crucial for improving the Pre-Feasibility Study economics and advancing ARR's goal of establishing a 100% domestic supply chain for critical minerals in the permanent magnet industry.

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.
