About Us

Low-Cost Operating Uranium Mining Company

Ur-Energy owns and operates the Lost Creek in-situ recovery uranium facility in south-central Wyoming which has produced ~2.8 million pounds of U3O8. In 2021, Lost Creek received an amendment to its license allowing expansion of mining activities within the existing Lost Creek Project and the adjacent LC East Project. The license now allows annual plant production up to 2.2 million pounds U3O8, which includes wellfield production of up to 1.2 million pounds U3O8 and toll processing of up to one million pounds U3O8. Additional approvals for this expansion are expected in 2023. Our second uranium in‑situ recovery facility, Shirley Basin Project, has received all major authorizations and is construction ready.

Ur-Energy engages in the identification, acquisition, exploration, development, and operation of uranium projects. Shares of Ur Energy trade on the NYSE American under the symbol “URG” and on the Toronto Stock Exchange under the symbol “URE." Ur-Energy’s corporate office is in Littleton, Colorado; its registered office is in Ottawa, Ontario.

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 Shirley Basin uranium project is construction ready with all major permits and licenses in hand.  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 recently been filed 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. Additional minor projects are ongoing to ensure the project is construction ready.

Our Leadership Team

Having decades of collective experience in the uranium and mining industries, our leadership team is the source of our success.

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.
