Welcome to our dedicated page for AMERICAN RARE EARTHS news (Ticker: ARRNF), a resource for investors and traders seeking the latest updates and insights on AMERICAN RARE EARTHS stock.
American Rare Earths Ltd (ARRNF) is a leading rare earth elements company with strategic projects at Halleck Creek in Wyoming and La Paz in Arizona. The company collaborates with the U.S. Department of Energy and Virginia Tech on metallurgical studies to extract REE from ore. Recent results indicate high REE recovery at low temperatures, validating project assumptions and lowering operating costs. Allanite, the primary REE-bearing mineral, shows promise due to its low crystallinity, enhancing leachability. ARR is well-positioned to benefit from U.S. tariff policy changes, aiming to meet the demand for locally sourced critical minerals. The company's focus on sustainable extraction and processing methods aligns with the clean energy transition.
American Rare Earths (ARRNF) has announced that its subsidiary, Wyoming Rare (USA), has secured a facility at the Western Research Institute in Laramie, Wyoming. This development follows a recent $7.1 million grant from the State of Wyoming for rare earth processing initiatives.
The facility will serve multiple purposes, including housing drill core and assay samples, and accommodating the construction of a pilot plant for processing capabilities. The Western Research Institute, a not-for-profit research organization, specializes in advanced energy systems, environmental technologies, and materials research.
This strategic partnership aims to advance the Halleck Creek Rare Earths Project and strengthen Wyoming's position in critical minerals development while supporting the company's mission to onshore critical mineral supply chains for the USA.
American Rare Earths (ARRNF) has announced final assay results from its 2024 drilling campaign at the Cowboy State Mine area within the Halleck Creek Project, Wyoming. The results revealed the highest-grade Total Rare Earth Oxide (TREO) intersections recorded at the site, with significant intervals including: 148.0m @ 4,451 ppm TREO, 161.5m @ 4,275 ppm TREO, and 90.0m @ 4,353 ppm TREO. Multiple high-grade intersections exceeded 5,000 ppm TREO. The company plans to complete an updated resource estimate and Pre-Feasibility Study (PFS) for Halleck Creek in 2025.
American Rare Earths (ARRNF) has engaged BMO Capital Markets as its financial adviser to accelerate the development of the Halleck Creek Project in Wyoming. BMO will explore strategic investments, joint ventures, mergers and acquisitions, and offtake agreements. This follows the establishment of Wyoming Rare USA Inc. as a dedicated U.S. subsidiary. The project, recognized as one of North America's largest rare earth deposits, has received support from Wyoming Energy Authority and a Letter of Interest from the U.S. Export-Import Bank. The engagement aims to position Halleck Creek as a cornerstone of the U.S. critical minerals supply chain, capitalizing on growing U.S. support for domestic critical minerals production.
American Rare Earths (ARRNF) announces the appointment of board member Melissa Sanderson as Co-Chair of the Critical Minerals Institute (CMI). With extensive experience in diplomacy and private sector leadership, Sanderson's appointment strengthens ARR's position in developing North American rare earth elements supply chains. Her role at CMI will enhance the company's influence in critical minerals advocacy and policy-making. The appointment follows her successful efforts in securing a Letter of Interest from the Export-Import Bank of the United States for ARR's development projects. The company operates the Halleck Creek Project in Wyoming and La Paz deposit in Arizona, potentially becoming North America's largest rare earth projects.
American Rare Earths (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) has received its first reimbursement of over US$304,000 (A$450,000) from the Wyoming Energy Authority (WEA) grant. This marks significant progress in developing the Cowboy State Mine at Halleck Creek. The reimbursement follows the approval of a US$7.1 million (A$10.7 million) non-dilutive funding grant on June 27, 2024. Funds will support ongoing initiatives including exploration drilling, baseline environmental studies, and prefeasibility assessments.
CEO Chris Gibbs stated that this reimbursement is important for executing their plans and de-risking the Cowboy State Mine, aiding in achieving their 2025 goals. The company owns Wyoming Rare (USA) Inc., focused on the Halleck Creek Project, WY, and the La Paz, AZ rare earth deposit. Both projects have the potential to become the largest and most sustainable rare earth projects in North America.
American Rare Earths (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) has successfully completed an extended 2024 drilling program at its Halleck Creek Rare Earths Project in Wyoming. The program included five additional reverse circulation (RC) drill holes, totaling 837 meters, focused on the western section of the Cowboy State Mine (CSM) deposit, an area known for higher-grade rare earth mineralization.
Key highlights include:
- Geophysical logging and detailed geological analysis of drill cuttings are underway
- Samples have been sent to ALS Global for formal assay
- Results are expected to contribute to resource model updates and long-term project development
CEO Chris Gibbs emphasized the importance of targeting high-grade zones to enhance the project's resource potential. The company will incorporate the new data into updated geological models and continue to inform the market as the program progresses.
American Rare Earths (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) has announced positive assay results from its 2024 drilling campaign at the Cowboy State Mine (CSM) area in Wyoming. The results confirm high-grade rare earth ore in the western portion of the deposit, with significant intercepts including:
- HC24-RM044: 172.4m @ 3,716 ppm TREO
- HC24-RM036: 51.0m @ 3,390 ppm TREO
- HC24-RM040: 30.0m @ 2,203 ppm TREO
The campaign has defined the eastern boundary of the Red Mountain Pluton and will now focus on higher-grade zones near Red Mountain. Four additional drill holes are planned to target these areas. The CSM area is part of the larger Halleck Creek deposit, which has a 2.34 billion tonne JORC resource containing 7.48 million tonnes of total rare earth oxides.
American Rare Earths (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) has announced that its subsidiary, Wyoming Rare (USA) Inc., received a non-binding Letter of Interest from the Export-Import Bank of the United States (EXIM) for a debt funding package of up to US$456 million. This funding is intended for the construction and execution phase of the Cowboy State Mine area at the Halleck Creek Project in Wyoming.
The debt financing will have a 15-year repayment term under EXIM's Make More In America Initiative. The Halleck Creek deposit has a 2.34 billion tonne JORC resource, containing 7.48 million tonnes of total rare earth oxides, including key magnet metals like Neodymium and Praseodymium oxides. This project is seen as the first step in a multi-phase approach to developing the Halleck Creek deposit, which has the potential to be a multi-generational rare earths asset for the U.S.
American Rare Earths (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) held productive initial meetings to accelerate the development of the Halleck Creek project through its wholly-owned subsidiary, Wyoming Rare (USA) Inc.
