Ur-Energy Inc. (NYSE:URG)(TSX:URE) (the "Company" or "Ur-Energy"), a domestic uranium producer with ISR projects that are among the largest and lowest-cost in the United States, is pleased to announce a significant regulatory milestone for its Shirley Basin Project. The Company has received final authorization from the Wyoming Department of Environmental Quality (WDEQ) Uranium Recovery Program (URP) to advance from limited operations to full-scale uranium in situ recovery (ISR) operations, including transport of uranium-loaded resin from its Shirley Basin ISR mine to the Company's Lost Creek processing facility.

The authorization follows a comprehensive preoperational inspection conducted by WDEQ staff pursuant to Radioactive Materials License WYSUA-2010. The WDEQ verified that all required safety systems, operating procedures, staffing, radiation safety programs and environmental monitoring programs were sufficient for safe operations and protective of human health and the environment.

Uranium recovery operations commenced at Shirley Basin in April 2026, and to date, an estimated 10,500 pounds of uranium have been loaded onto resin. Shipments of loaded resin to Lost Creek will commence in the coming weeks as wellfield flow rates are steadily increased to full commercial levels.

Integrated Satellite Production Strategy

The authorization advances Shirley Basin into full wellfield recovery operations and enables uranium-loaded resin to be transported to Lost Creek for final processing and recovery. By leveraging Lost Creek's established central processing plant for elution, precipitation, drying and drumming, Ur-Energy avoids duplicative infrastructure, improves capital efficiency and supports the scalable ramp-up of its second ISR operation.
