American Rare Earths reports High-Grade TREO results at Halleck Creek’s Red Mountain area

Proactive - Interviews for investors

American Rare Earths CEO Chris Gibbs joined Steve Darling from Proactive to announce new assay results from the company’s ongoing mapping and channel sampling program at the Cowboy State Mine area of the Halleck Creek Rare Earths Project in Wyoming. The results further confirm the project's potential to become a major U.S.-based source of critical minerals. Gibbs shared that a total of 106 channel samples were collected across the Red Mountain area, a key target within the Halleck Creek project. Assay results revealed elevated levels of rare earth mineralization, with one standout sample grading 1.37% Total Rare Earth Oxide (TREO). Across the Red Mountain Pluton — the rare earth-bearing lithology — TREO grades ranged from 711 parts per million (ppm) to 13,651 ppm, with an average of 3,661 ppm. Notably, the company reported that magnet rare earth oxides, which are essential for high-performance magnets used in electric vehicles and wind turbines, account for approximately 28% of the total rare earth content. Heavy rare earth oxides, which are typically rarer and more valuable, represent about 13%. Fifteen of the collected samples exceeded 4,500 ppm TREO, further underscoring the presence of elevated-grade zones within the Red Mountain system. The company is currently incorporating the new channel sampling data into an updated geological model and mineral resource estimate for the CSM area. These updates will inform the ongoing mine planning process and play a key role in the upcoming Pre-Feasibility Study, which remains on track for completion in late 2025. #proactiveinvestors #americanrareearthslimited #asx #arr #otcqx #arrnf #adr #amrry #wyomingrareinc #AmericanRareEarths #HalleckCreek #CowboyStateMine #CriticalMinerals #Neodymium #Praseodymium #Yttrium #Dysprosium #MiningUpdate #PFS #ChannelSampling #ProactiveInvestors
