Ur-Energy Commences Operations at its Shirley Basin ISR Project, Wyoming, Advancing U.S. Uranium Production
Tagline: Ur-Energy Executes Shirley Basin Start-Up While Managing Debt Load and Regulatory Hurdles

Executive Summary
- On April 23, 2026, Ur-Energy announced the commencement of uranium mining operations at its Shirley Basin ISR Project in Wyoming.
- Uranium-bearing solution is currently being captured from Mine Unit 1 following successful construction and permitting.
- Transport of uranium-loaded resin to the existing Lost Creek facility for final processing is expected this summer, pending additional regulatory inspection and approval.
- The project has a licensed annual capacity of up to 2.0 million pounds U3O8, with an anticipated mine life of nine years across three shallow mining units.
- Combined with Lost Creek, total company licensed production capacity reaches 4.2 million pounds U3O8 annually.
Material Impact
- The news confirms the execution of a timeline previously guided by management in November 2025 (anticipated startup Q1 2026).
- While operationally significant, the actual revenue contribution is delayed until resin transport approval is granted later in summer 2026.
- This announcement validates the capital deployment from the December 2025 $140 million convertible notes offering but does not introduce unexpected upside relative to prior guidance.
- The transition from development to production reduces execution risk, yet regulatory dependency for resin transport introduces a near-term variable that prevents this from being classified as "Material - Positive" or a game changer at this specific moment.
