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 3.0 million pounds of U₃O₈ since commencing production in 2013. 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.

Ur-Energy’s second ISR facility, the Shirley Basin Project in Carbon County, Wyoming, is fully licensed and permitted, with construction nearly complete. Commissioning is expected to commence in Q1 2026, positioning Shirley Basin to become the fifth producing ISR uranium operation in the United States. 

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.  Our second ISR uranium project, Shirley Basin is on target for commissioning in early 2026. Read our Initial Assessment Technical Report Summaries for Lost Creek Property and Shirley Basin under Technical Reports.

Our Shirley Basin Project

Our newest uranium in situ project, Shirley Basin, is a part of our acquisition of Pathfinder Mines Corporation in 2013. We also acquired all the historic geologic and engineering data for the project, which has nearly 3,200 historic drill holes.

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. 

All major permits for the Shirley Basin Project, including the BLM Plan of Operations, Land Quality Division Permit to Mine and associated aquifer exemption, and Uranium Recovery Program License have been received. We expect to commence operations at Shirley Basin in early 2026.

Cautionary Note Concerning Disclosure of Mineral Resources:

As we are required to do, the mineral resource estimates referred to on our website and included in the “S-K 1300” reports linked on the Technical Reports page on this site, have been prepared in accordance with U.S. securities laws pursuant to Regulation S-K, Subpart 1300 (“S-K 1300”). Prior to these estimates, we prepared our estimates of mineral resources in accord with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves (“CIM Definition Standards”). NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for public disclosure an issuer makes of scientific and technical information concerning mineral projects. We are required by applicable Canadian Securities Administrators to prepare and file in Canada an NI 43‑101 compliant report when we file an S-K 1300 technical report summary. The NI 43-101 and S-K 1300 reports (for each of the Lost Creek Property and Shirley Basin Project) that are linked on the Technical Reports page are substantially the same except for internal references to the regulations under which the report is made, and certain organizational differences.
