Veteran mine builder Matthew Gili will join American Rare Earths Ltd (ASX:ARR, OTCQX:ARRNF)’s board as a non-executive director as the company advances the Halleck Creek Rare Earths Project in Wyoming and prepares for a planned Nasdaq compliance listing in H2 2026.

Gili is currently president and CEO of Ur-Energy Inc, a NYSE American and TSX-listed Wyoming uranium producer, and brings more than 25 years of mine development and operational experience across major global mining groups including Rio Tinto and Barrick.

His appointment remains subject to completion of Australian regulatory formalities, which American Rare Earths expects to be completed shortly.

Once formally appointed, Gili will join the company’s Technical Committee and contribute to the Definitive Feasibility Study workstream at Halleck Creek, which American Rare Earths describes as the largest known rare earth deposit in the United States on a total rare earth oxide basis.

Board renewal ahead of US listing plans

The appointment forms part of a broader board renewal process as ARR works toward a Nasdaq compliance dual-listing in H2 2026, while retaining the ASX as its primary listing.

The company is also considering a full US domicile in 2027, subject to a prospective shareholder vote.

CEO Mark Wall said Gili’s operational experience and Wyoming background would strengthen the board as Halleck Creek moves toward construction and production.

“The intended addition of Matt to our Board of Directors further demonstrates our commitment to advancing the largest rare earth element deposit on a total contained rare earths basis in the United States toward construction and operations. Matt brings a tremendous blend of mining technical expertise and Wyoming-specific experience to both the Board and the Technical Committee. His depth of operational knowledge, his relationships in Wyoming, and his proven track record of delivering world-class mining projects, including building the first new copper mine in the United States in a decade, make him exactly the right person to help us get Halleck Creek built.

“As we progress toward our NASDAQ listing later this year, appointments of this calibre send a clear message to U.S. investors about the quality of the team and the seriousness of our intent. Matt’s experience managing ISR uranium operations in Wyoming gives him first-hand knowledge of the hydrometallurgical processing chemistry that will be central to bringing Halleck Creek into production. The parallels between uranium and rare earth processing are substantial and practically meaningful. This is not simply a credential; it is operational expertise that will directly benefit our Technical Committee and Feasibility Study.”
