American Rare Earths Ltd (ASX:ARR, OTCQX:ARRNF) has consolidated its president and chief executive officer roles, appointing current CEO Mark Wall to the combined position effective immediately.
The move is intended to sharpen decision-making and strategic alignment as it progresses its flagship Halleck Creek rare earths project in Wyoming and advances preparations toward a potential US listing.
Wall, who is based in North America, said Halleck Creek has been his “main focus area” since joining as CEO and flagged plans to accelerate project execution as part of efforts to support a domestic US “mine-to-magnet” rare earths supply chain.
“In parallel, we are preparing to conduct a Whole of Property Assessment of the greater American Rare Earths Halleck Creek 2.63 billion tonne resource to understand what the overall development plan may look like,” Wall said.
He also pointed to an Opportunity Assessment underway at the company’s La Paz property in Arizona, with a focus on reviewing additional mineral potential including copper and gold, alongside ongoing work to “build and streamline” the team to progress the portfolio.
Mixed rare earths
In late January, American Rare Earths produced mixed rare earths oxide (MREO) from ore sourced at its Halleck Creek project during the December 2025 quarter, using an updated mineral processing flowsheet in what it described as a key technical milestone.
The company said quarter-on-quarter work progressed on several fronts, including metallurgical processing and beneficiation optimisation, alongside ongoing efforts to refine resource definition at Halleck Creek. Corporate activity during the period also included leadership changes.
