24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Recent Halleck Creek updates, including pilot plant, studies, and leadership changes, have produced generally modest single-day price moves, with both aligned and divergent reactions to operationally positive news.
Over the past month, American Rare Earths has focused on advancing the Halleck Creek project through technical and strategic steps. On Mar 25, it added a former Newmont executive as VP Corporate Development and Strategy, which coincided with an 8.57% move. Subsequent news detailed an accelerated pilot plant, an Oxides to Metals study, and a Whole of Property Development Assessment. These items underscored scaling and processing plans but produced smaller price reactions. Today’s leadership and project-delivery appointments continue that theme of building execution capability around Halleck Creek.

DENVER, April 28, 2026 (GLOBE NEWSWIRE) -- American Rare Earths Limited (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) (“American Rare Earths” or the “Company”) today announced the appointment of Wheatland, Wyoming resident Brook Brockman as Director of Public and Government Affairs for its wholly owned subsidiary, Wyoming Rare (USA) Inc. (“Wyoming Rare”), and Taylor Cable as Director, Projects & Engineering to further strengthen the Company’s technical and project execution capabilities for its flagship Halleck Creek rare earths project in Platte and Albany Counties, Wyoming.
Based in Wheatland, Brook will lead community, government, and business engagement for Halleck Creek, bringing a strong track record of Wyoming-based leadership and service, with experience across agriculture, conservation, and rural economic development. She serves as an at-large board member of the Platte County Resource District, which works to conserve soil, water, and natural resources across the county, giving her practical insight into local land and water issues.
Based in nearby Denver, Taylor is an engineering and capital projects leader with deep experience developing and delivering mineral processing and heavy industrial facilities from early technical studies through EPC/EPCM execution, construction, and commissioning. Over his career, he has translated feasibility work into executable projects and managed engineering firms, technical consultants, and contractors to deliver complex processing facilities, with a particular focus on de-risking the transition from studies into detailed engineering and construction.
American Rare Earths CEO Mark Wall said, “The appointments demonstrate the Company’s commitment to advancing Halleck Creek with strong local relationships and disciplined project execution.”
“I am thrilled to welcome Brook and Taylor to the American Rare Earths and Wyoming Rare team. Brook’s deep knowledge of Wyoming and her connection to Platte and Albany Counties are essential as we work to advance the largest contained rare earth elements resource in the domestic United States1. At the same time, Taylor’s extensive background in mineral processing, project delivery, and capital projects will further strengthen our technical team as we move toward the next phase of study and project execution at Halleck Creek.”
In her new role, Brook will focus on:
· Building strong, transparent relationships with community members, landowners, and local businesses in Platte and Albany Counties.
· Engaging with county, state, and federal officials to support a permitting and regulatory path that reflects Wyoming’s values and priorities.
· Supporting local initiatives in agriculture, conservation, and workforce development that align with the project’s long-term presence in the state.
In his new role, Taylor will focus on:
· Supporting the progression of Halleck Creek from technical studies into front-end engineering, and ultimately into detailed design, construction, and commissioning.
· Coordinating metallurgical consultants, process engineers, and equipment vendors to translate the project’s process flowsheet into an executable plant design and capital cost estimate.
· Partnering with executive, finance, technical, and operations teams to ensure that study outputs and execution strategies are aligned with the Company’s strategic priorities.
“As a Wyoming native, I care deeply about the future of our communities, our working lands, and the opportunities we create for the next generation,” Brook said. “I’m excited to help American Rare Earths and Wyoming Rare work side by side with families, ranchers, businesses, and officials in Platte and Albany Counties as we advance the Halleck Creek project in a way that reflects Wyoming’s strong sense of stewardship and independence.”
Taylor said he is looking forward to helping advance Halleck Creek toward execution.
“Halleck Creek is a rare opportunity to develop a large-scale, strategically important rare earths project in a mining-friendly jurisdiction,” Taylor said. “My focus will be on de-risking the transition from studies into engineering and construction, ensuring our technical assumptions, cost estimates, and execution strategies are aligned before major capital is deployed.”
Halleck Creek hosts the largest known deposit of total contained rare earth oxides in the United States, positioning Wyoming to play a strategic role in strengthening domestic supply chains critical to advanced manufacturing, defense, and future technologies. With Brook’s leadership in public and government affairs and Taylor’s experience in project development and execution, American Rare Earths aims to ensure that Halleck Creek’s development is grounded in strong local relationships, robust technical work, and disciplined capital stewardship.
