1. Nature of Operations

Ur-Energy Inc. (the “Company”) was incorporated on March 22, 2004 under the laws of the Province of Ontario. The Company continued under the Canada Business Corporations Act on August 8, 2006. The Company is an exploration stage issuer, as defined by U.S. Securities and Exchange Commission (“SEC”). The Company is engaged in uranium mining and recovery operations, with activities including the acquisition, exploration, development, and production of uranium mineral resources located primarily in Wyoming. The Company commenced uranium production at its Lost Creek Project in Wyoming in 2013.

Due to the nature of the uranium recovery methods used by the Company on the Lost Creek Property, and the definition of “mineral reserves” under Subpart 1300 to Regulation S-K (“S-K 1300”), the Company has not determined whether the properties contain mineral reserves. This was true while the Company reported its mineral resources pursuant to National Instrument 43-101 (“NI 43-101”), which uses the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards. The Company’s report The Lost Creek ISR Uranium Property, Sweetwater County, Wyoming, March 7, 2022 and as amended on September 19, 2022 (the “Lost Creek Report”) outlines the potential viability of the Lost Creek Property as of December 31, 2021. The recoverability of amounts recorded for mineral properties is dependent upon the discovery of economic resources, the ability of the Company to obtain the necessary financing to develop the properties and upon attaining future profitable production from the properties or sufficient proceeds from disposition of the properties.
