American Rare Earths strengthens board with veteran Wyoming mine builder ahead of planned Nasdaq listing
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.”

Wyoming authorities call on Rocky Mountain Power to explain role in massive November power outage
by Dustin Bleizeffer, WyoFile
The massive, multiple-utility power outage last fall that left some 250,000 customers across parts of Wyoming, South Dakota and Montana without electricity was the result of miscommunication and inadequate procedures during planned maintenance that required de-energizing a power line in southcentral Wyoming, according to a report.
The Nov. 13 incident left thousands of homes and businesses without power for 9.5 hours — longer, in some cases — and knocked out a coal-powered generator outside Glenrock. The unit at the Dave Johnston Power Plant remains offline, leaving Rocky Mountain Power to backfill some 300 megawatts of electricity — enough to power about 225,000 homes.
Without expressly assigning blame to any one party, the report — conducted by the Western Electricity Coordinating Council and the North American Electric Reliability Corporation — indicates a series of communication breakdowns between PacifiCorp (parent company of Rocky Mountain Power), the Western Area Power Administration and, to some degree, electrical grid coordinating teams.
While it’s unclear whether authorities such as the North American Electric Reliability Corporation might pinpoint fault and assess penalties, the Wyoming Public Service Commission has called on Rocky Mountain Power to appear at a hearing scheduled for 2:30 p.m. Wednesday. The commission wants to hear from the utility about “the specifics and details of the event and report,” a public notice announced, and it “may consider and take any action that is in the public interest.”
The hearing at the Public Service Commission’s office located at 2515 Warren Avenue, Suite 300, in Cheyenne, will also be livestreamed at this link.
What happened
According to the 49-page report published in June, PacifiCorp and the Western Area Power Administration were coordinating maintenance on their respective systems that, together, required temporarily de-energizing PacifiCorp’s Aeolus–Clover 500 kilovolt line, which runs east-west and is anchored, in part, by a substation near Medicine Bow.
The effort also required curtailing some local wind energy from feeding the grid, according to the report. But on the day of the planned maintenance, Nov. 13, there was confusion about whether the Western Area Power Administration would scrap its work, so wind energy wasn’t curtailed as originally planned.

The report indicates that modeling tools might have failed to accurately measure local grid conditions, so when the power line was de-energized, “power flow rapidly redistributed throughout the northeast portion” of the local grid. “Within six seconds,” according to the report, “an electrical island formed and collapsed, causing widespread effects across that portion of the interconnection.
“The disturbance,” the report continues, “culminated in the loss of more than 4,800 [megawatts] of generation from coal, natural gas, photovoltaic and wind resources.”
The cascading power failure began at about 12:45 p.m. on a Thursday, dragging down portions of service territories operated by Rocky Mountain Power, Black Hills Energy, Montana-Dakota Utilities and some rural electric co-ops.
The report points to failures in communication, process deficiencies and inadequate modeling tools. Wind energy was not “identified as a contributing factor,” according to the report. It credits both battery storage and wind energy throughout the impacted area for supporting “a faster frequency recovery across the interconnection” and for providing “readily available capacity during system restoration.”
