American Rare Earth Channel sample program program highlights

Highlights

• Channel samples over the Cowboy -State -Mine were returned to 13,651 ppm (1.37%)
• 15 out of 106 rehearsals exceeded 4,500 ppm Treo
• Magnet of rare inoxides (MREO) was an average of 1,023 ppm, approximately 28% of the total Treo composition
• Heavy rare inoxides (HREO) was an average of 464 ppm, which corresponds to ~ 13% of the Treo composition
• The results are included in the resource model to support the feasibility study that will remain up to date at the end of 2025

Denver, May 8th, 2025 (Globe Newswire) – American less often bounded (ASX: Arr | Otcqx: Arrnf | Adr: Amrry) (ARR or the company) It is pleased to report the results from a mapping and channel sample program in the entire Cowboy State Mine (CSM) area, part of the Halleck Creek Rare Earths project in Wyoming. A total of 106 samples of geologists from Wyoming Rare (USA) Inc (WRI), ARR, were collected in collaboration with technical support for geosyntec geologists from Wyoming Rare (USA) Inc (WRI).

The Assay results confirmed an increased mineralization of rare earth in the entire area of ​​the Red Mountain, including an outstanding sample, which rates 1.37% (13,651 ppm) total -erdoxide (Treo). The Treo grades from Red Mountain Pluton (RMP), the rare earth -bearing rock type, was between 711 ppm and 13,651 ppm with an average of 3,661 ppm. On average, magnet rare inoxides¹ (MREO) account for approximately 28% of the total rare earth content (1,023 ppm), while severe rare earth oxides oxides² (HREO) represent around 13% (464 ppm). A total of 15 samples exceeded 4,500 ppm Treo, which indicates areas of material with increased quality material within the system.

These results continue to underline the southern part of the Red Mountain as the hosting of one of the previously observed materials with the highest degree that has been observed for the CSM area. The channel trial data is currently being integrated into an updated geological model and a mineral resource estimate for the CSM area. This model supports the planning of the mines and the support of the preparation study, which will remain up to date at the end of 2025.

Chris Gibbs, Chief Executive Officer, said:
“Halleck Creek is developing into the next major rare rare earth project in the USA. With the high-quality core, four magnetic-selenium earths, including neodymium, praseodym, dyprosium and terbium, which are consistently available in the cowboy state mine, we deliver one of the few US projects to provide these critical materials, these critical materials to deliver in the scaling.

The persistent confirmation of these four rare earths in the entire area is particularly encouraging. In particular, terbium and dyprosium are of crucial importance for the performance of high -temperature magnets and remain in extremely limited care outside of China. Based on our scoping study, you are expected to contribute over 25 percent of project income, even though you are a small percentage of the entire tonnage.

It is important that we do not need federal approval reform to get ahead. If you are in state countries in Wyoming, you will receive a clear and rationalized path to development. In view of the latest export bans in China on terbium and dyprosium, the national importance of Halleck Creek was never clearer as a safe domestic source.

As described in our updated scoping study³A staged development could recognize the first production as early as 2029. With her scale, simplicity and multi-generation potential, Halleck Creek has the properties of becoming one of the most important rare earth projects in America. “

Limited to American rare earths:

American rare earth (ASX: Arr through his 100 % subsidiary Wyoming Rare (USA) Inc. (“WRI”) The company drives the Halleck Creek project in Wyoming a deposit of rare earth with potential to secure critical mineral independence for America for generations. The Wyoming State Land and offers cost-efficient mining mining methods and advantages of optimized approval procedures in this mining-friendly state.

Haleck Creek is strategically positioned with plans for mineral processing and separation facilities in order to reduce the dependence on the USA into imports that are sufficient under China – and at the same time the growing demand for elements of the rare earth that are essential for defense, advanced technologies and economic security. In the course of the exploration, the undeveloped potential of the project increases its importance for both state and federal areas as the cornerstone of the security of the US supply chain. In addition to its resource potential, American is involved in rare Earths for environmentally friendly mining practices and continues to work with state-supported F&-programs to develop innovative extraction and processing technologies for rare elements.
