LITTLETON, CO / ACCESSWIRE / May 30, 2023 / Ur-Energy Inc. (NYSE American:URG)(TSX:URE) (the "Company" or "Ur-Energy") is pleased to announce the successful startup of production flow from Header House 2-4 at our Lost Creek In Situ Uranium Facility in Sweetwater County, Wyoming. Production rates will continue to increase as additional header houses in Mine Unit 2 come online this year. Lost Creek production inventory will be sold into our remaining 2023 contract book of 180,000 pounds U₃O₈ in the second half of the year. Beginning in 2024, the Company's total sales quantity under contract is 600,000 pounds U₃O₈ annually, plus or minus a small, optional flex.

We are also pleased to announce that construction of our Casper, Wyoming centralized services facility, shown below, is complete and will facilitate full laboratory and construction services for each of our mining projects. The centralized location will allow for reduced drive times and improved safety for our employees while reducing operating costs and increasing efficiencies.

Steve Hatten, the Company's COO stated, "I am very excited to see the planning and hard work pay off for our long-standing and new employees with these achievements at Lost Creek and completion of our new Casper facility. This restart of normal operations at Lost Creek marks the first of a series of planned production areas scheduled for 2023 and 2024. We hope our return to commercial production also is the beginning of a resurgence of the uranium mining industry in the United States."
