Massive US Rare Earths Project Is Larger Than Previously Expected

Rhea-AI Summary

American Rare Earths Limited (ASX: ARR, OTCQB: ARRNF) has announced a significant increase in the Exploration Target for its Halleck Creek project in Wyoming, underscoring its potential as one of the largest rare earth projects in the USA. The updated estimate reveals between 1.01 and 1.27 billion tonnes of mineralized rock with total rare earth oxide grades of 2,245 to 2,807 ppm. A recent capital raise has strengthened the company's balance sheet, enabling accelerated exploration efforts. The maiden drill campaign has shown promising results with consistent rare earth mineralization.

Positive

• Halleck Creek project exploration target increased to 1.01 - 1.27 billion tonnes, a 328% increase from previous estimates.
• Total rare earth oxide grades range from 2,245 ppm to 2,807 ppm, indicating high-quality mineralization.
• Successful maiden drilling campaign with consistent rare earth mineralization.
• Strengthened balance sheet from recent capital raise supports accelerated exploration and resource definition.

Negative

• None.

PHOENIX, Sept. 01, 2022 (GLOBE NEWSWIRE) -- American Rare Earths Limited (ASX: ARR, OTCQB: ARRNF, FSE: 1BHA) (ARR or ‘the Company’) is pleased to announce a substantial increase to the Exploration Target for the Halleck Creek (Albany Co., Wyoming) project, again confirming its potential to be one of the largest, Rare Earth Projects in the USA.

Globally, very few rare earths projects exceed either one billion tonnes of mineralized rock or one million tonnes of total rare earth oxide content. The Halleck Creek Project may be in very rare company. Furthermore, low penalty elements, access to infrastructure and location in a mining friendly jurisdiction set this project apart. The Company’s strengthened balance sheet, from the recent successful capital raise allows for accelerated efforts to define a high tonnage maiden Resource, advance metallurgy test work and fast track evaluation studies in the near term.

Managing Director and CEO Chris Gibbs commented: “The Halleck Creek project is shaping up to become a world class asset. The maiden drill campaign was a resounding success, and the new exploration target is massive. Assay results exceeded our expectations with consistent Rare Earth mineralization observed throughout the deposit. We continue to expand the project footprint and the deposit remains open at depth and laterally. We are looking forward to advancing this project and continue increasing shareholder value.”

Exploration Target Update
ARR updated the JORC* compliant Exploration Target estimate based on the latest surface sampling, and 2022 maiden drilling results. The updated exploration targets outline between 1.01 and 1.27 billion tonnes of rare earth mineralized rocks with total rare earths oxide (TREO) grades ranging between 2,245 ppm and 2,807 ppm (Figure 1 and Figure 2). Readers are advised that the potential quantity and grade of the Halleck Creek resource are conceptual in nature, and there has been insufficient exploration to estimate a Mineral Resource. This is an update and increase from the original Exploration Target reported by the company on November 4. 2021. The mass of mineralized rocks is 328% larger than previously estimated.

*The Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code) establishes standards for public reporting, emphasizing principles of transparency and materiality. All companies listed on Australian or New Zealand Stock Exchanges are required to comply with the JORC Code.

Next Steps

Completing the drilling campaign at Halleck Creek will be the focus of the Company's operational personnel in the near term. The data collected from this drilling will be used to prepare the first detailed geological models of the area and then define the maiden JORC compliant resource in early 2023.

About American Rare Earths
American Rare Earths Limited (ASX: ARR, OTCQB: ARRNF, FSE: 1BHA) is an Australian company listed on the ASX with assets in the growing rare earth metals sector of the United States of America, emerging as an alternative international supply chain to China's market dominance of a global rare earth market expected to expand to US$20 billion by the mid-2020s. The Company's mission is to supply Critical Materials for Renewable Energy, Green Tech, Electric Vehicles, National Security, and a Carbon-Reduced Future.

Western Rare Earths (WRE) is the wholly owned US subsidiary of the Company. ARR owns 100% of the world-class La Paz Rare Earth Project, located 170km northwest of Phoenix, Arizona. As a large tonnage, bulk deposit, La Paz is potentially the largest, rare-earth deposit in the USA and benefits from containing exceptionally low penalty elements such as radioactive thorium and uranium.

In the first half of 2021, ARR acquired the USA REE asset, the Halleck Creek Project in Wyoming. Since acquiring the asset, the company has increased the land holding to over 6,000+ acres. Approximately 1,015 to 1,268 million tonnes of rare earths mineralised rocks were identified as an exploration target for the Halleck Creek project area with an average Total Rare Earth Oxide (TREO) grade of 2,245 - 2,807 ppm.

La Paz and Halleck Creek's mineral profiles are incorporated into emerging US advanced rare earth processing technologies in collaboration with US national laboratories, major universities and the US DOE innovation hub, the Critical Materials Institute.
