UR-ENERGY CELEBRATES 100TH SHIPMENT OF YELLOWCAKE FROM LOST CREEK ISR URANIUM MINE, WYOMING

Ur-Energy Inc. has completed its 100th shipment of U3O8 (triuranium octoxide) concentrate (yellowcake) from its flagship Lost Creek ISR facility in Wyoming.

The milestone shipment departed the Lost Creek plant on June 11, 2026, and brings Ur-Energy's total pounds of U3O8 shipped to over 3.5 million since operations began in 2013. The 100th shipment marks more than a decade of safe, reliable U.S. uranium production and underscores Ur-Energy's established role in supporting the domestic nuclear fuel supply chain.

Steve Hatten, chief operating officer, commented: "Achieving our 100th shipment is a powerful testament to the operational excellence and consistency of our team at Lost Creek. For more than a decade, this facility has proven the efficiency and reliability of our ISR platform. Delivering more than 3.5 million pounds into the supply chain isn't just a historical milestone; it establishes the operational blueprint we are now executing to drive production growth across our portfolio."

Lost Creek remains the cornerstone of Ur-Energy's production strategy. With the company's second ISR uranium facility, Shirley Basin, having successfully initiated operations in April, 2026, Ur-Energy is uniquely positioned to scale production to support the expanding demand for secure, domestic nuclear fuel.
