American Rare Stock Price, News & Analysis

American Rare Earths (OTCQX:AMRRY) announced the appointment of Mark Wall as CEO effective January 5, 2026, to lead its transition from explorer to U.S. rare earths producer. Key operational milestones cited include an upgraded mineral resource estimate for Halleck Creek, impurity-removal testwork breakthroughs in the processing flowsheet, an expanded relationship with Tetra Tech, and advancement of a prefeasibility study plus plans for a demonstration plant. Management also said it is evaluating a potential U.S. listing and pursuing U.S. government funding pathways to support project financing and permitting.

The Board highlighted Mr. Wall’s 30+ years of mining experience and said leadership will focus on study completion, demonstration plant delivery, funding pathways, and preparing for a potential U.S. listing.

American Rare Earths (ADR: AMRRY) on Nov 20, 2025 expanded its relationship with Tetra Tech (NASDAQ: TTEK) to include exploring and applying for U.S. Government funding for the Company's Flagship Halleck Creek project.

Tetra Tech, a long‑time technical partner since 2023, will continue mineral processing testing and engineering while advising on strategic engagement with federal agencies to pursue funding opportunities intended to accelerate project development and secure domestic supply of magnet metals.

The company cited the Federal Government mandate to build critical minerals supply chains and described Halleck Creek as a potential solution to diversify U.S. rare earth upstream supply amid a single producing REE mine domestically.

American Rare Earths (ADR: AMRRY) updated the Cowboy State Mine (CSM) mineral resource estimate to 547.5 million tonnes at a 1,000ppm TREO cut-off after incorporating 102 channel samples and geological re-modelling.

Key outcomes: 63.9 million tonnes were reclassified from inferred to indicated; mapping added ~4.5 million tonnes; a standout channel sample returned 13,816 ppm TREO. ARR secured permits for 27 drill holes at CSM and 29 holes at Bluegrass to support in-fill and exploration drilling ahead of technical studies beyond the pre-feasibility study.

American Rare Earths (ASX:AMRRY) presented its 2025 AGM Chairman's Address outlining progress at the Halleck Creek Rare Earths Project and next steps for FY2026. Key disclosed milestones include a JORC resource of 2.63 billion tonnes at 3,292 ppm TREO, successful processing advances including atmospheric tank leaching and impurity removal using magnesium oxide, and completion of test mining of 3,080 tonnes at Cowboy State Mine in Sept 2025. Corporate funding moves comprised a A$15m placement at A$0.32, A$5.784m from option exercises, A$1m promissory note repayment, and a US$456m non-binding letter of interest for project finance. A PFS is targeted for 2026 and a beneficiation demonstration plant is planned.

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.
