Ur-Energy Inc.

About Us

Low-Cost Operating Uranium Mining Company

Ur-Energy is a U.S. uranium mining company focused on developing and operating in-situ recovery (“ISR”) uranium projects in Wyoming. The Company owns and operates the Lost Creek ISR uranium facility in south-central Wyoming, which has produced more than 3.5 million pounds of U₃O₈ since commencing production in 2013. Ur Energy's second ISR facility, the Shirley Basin Project in central Wyoming, commenced operations in April 2026. Lost Creek’s license and permits allow annual plant production of up to 2.2 million pounds of U₃O₈, including wellfield production of up to 1.2 million pounds and toll processing of up to 1.0 million pounds. The combined annual licensed production and toll processing capacity of Lost Creek and Shirley Basin is 4.2 million pounds U₃O₈.

Uranium in Wyoming – Our Lost Creek Property, Shirley Basin Project and Beyond

Our Wyoming properties together total approximately 48,000 acres of mineral property rights and include our Lost Creek Property in the Great Divide Basin and our Shirley Basin Project. Lost Creek has been in operation, producing uranium to fuel clean energy, since 2013.  Construction of our second ISR uranium project, Shirley Basin, is well advanced and we plan to commence production and commission Shirley Basin operations in 2026. Read our Initial Assessment Technical Report Summaries for Lost Creek Property and Shirley Basin under Technical Reports.

Our Shirley Basin Project

Shirley Basin, our second uranium in situ recovery (“ISR”) project, was acquired through our 2013 purchase of Pathfinder Mines Corporation. In April 2026, we commenced initial operations to extract and capture U₃O₈ at Shirley Basin, marking the return of a historic ISR district to active operations. The project is designed as a satellite facility integrated with our Lost Creek processing plant, where U₃O₈ captured on resin at Shirley Basin will be transported for final processing, drying, and drumming. We expect to begin transporting uranium-loaded resin from Shirley Basin to Lost Creek in summer 2026, subject to receipt of final regulatory approvals.

An Initial Assessment Technical Report Summary on Shirley Basin ISR Uranium Project, Carbon County Wyoming (the “Shirley Basin Report,” as amended, March 11, 2024) has been completed which confirms the project’s mineral resource estimate of 8.8 million pounds eU3O8 in the Measured and Indicated categories, of which approximately 6.4 million pounds are expected to be recovered. Due to the very high level of density in drilling at the project, all resources within the three proposed mine units are classified as Measured or Indicated. There are no resources in the Inferred category.
