Ur-Energy Provides Q1 Update on Operations and Activities Supporting Ramp Up at Lost Creek

LITTLETON, April 12, 2023 - Ur-Energy Inc. (NYSE American:URG)(TSX:URE) ("Ur-Energy" or the "Company") is pleased to provide an update on Q1 operations and activities related to ramp up at its Lost Creek In-Situ Recovery Project ("Lost Creek") and ongoing construction at its Casper, Wyoming Operations Headquarters.

The Company announced in December 2022 that we have secured sufficient long-term sales commitments to warrant ramp up of operations at Lost Creek to levels sufficient to deliver into those contracts. With sales commitments currently totaling 3.2 million pounds U₃O₈ through 2028 (600,000 pounds U₃O₈ per year beginning in 2024, +/- a small flex) we would like to detail recent and ongoing activities that will enable us to meet our production targets.

Significantly, recruitment of personnel has progressed to the point where all necessary operations staff are onboard to support required regulatory, safety, drilling, construction, wellfield, and plant activities. New hires have been safety trained and are at various stages of training with respect to their operating positions. We are pleased to share that our employees are again being recruited from many Wyoming communities including Casper, Rawlins, Riverton, Lander, and additional smaller nearby towns. The total number of employees assigned to Lost Creek is approaching 50, with several more management and support staff based in Casper and in Littleton, Colorado. Additional interviews and hiring continue for the remaining open positions.

While the Wyoming winter of 2022-2023 has been particularly harsh, we have been able to advance many of our objectives making it possible to begin ramping up production in Q2 2023. Our earlier drilling and well installation activities mean that Header House (HH) 2-4 is ready for final surface construction. In addition, the Geology and Drilling departments have completed, and are evaluating, delineation in HHs 2-5 through 2-9. Well installation has also progressed substantially into HH 2-5 to make it ready for construction when HH 2?4 is complete. Despite continuing supply chain challenges, the team has pre-purchased and stored material for upcoming drilling.

Surface construction has also advanced significantly, including installation of the pipeline and powerline to HH 2-4. Trenching, pipe and wire placement to all individual wells is complete and the HH 2-4 building is set on its foundation. Work now focuses on making final electrical, piping and instrument terminations with the goal of bringing the house into production in 2023 Q2. Again, staff have been proactive in ordering long lead-time materials required for the construction team to meet the upcoming timelines required for sales deliveries.

Our delineation drilling program saw 120 delineation holes completed within MU2 to facilitate final wellfield design for the next four header houses. This program was successful in providing better definition of resources and increased the confidence level of resources from the Indicated and Inferred categories to the Measured category with virtually no loss of resource, nor reduction in grade. This is further assurance that our current geologic evaluation and resource estimation methodologies are appropriate and accurate for the deposit, which is key for efficient production planning and design as we move forward with ramp up.

The primary target for the delineation drilling was the roll front system within the HJ Horizon which is the current production zone for MU2. In addition to the results within the HJ horizon, mineralization was routinely intersected in the underlying KM horizon. The KM resource in this discrete area has been characterized as Resource Area 12 (RA12) in our Lost Creek Property Technical Report Summary ("Lost Creek ISR Uranium Property, Sweetwater County, Wyoming, USA" September 19, 2022). RA12 is one of 12 resource areas for which a mineral resource has been calculated at Lost Creek. The KM resource in RA12 remains under-defined with much of the mineralization open-ended, highlighting potential resource growth with additional drilling which is scheduled to continue in this area during Q2 and Q3.

Additionally, along the northern edge of the drilled area, a deeper portion of the mineralized redox trend was encountered which was unexpected and lower in the section than currently identified roll front horizons. The best mineralized intercept recorded at this level was 17.5 ft. of 0.05% eU₃O₈ (0.88 GT) at a depth of 686.5 feet. This is an indication that the regional trough of oxidation that controls the mineralized system deepens and extends to the north where there currently is no drill data within approximately 3,000 feet. This newly identified portion of the trend is testament, again, to the resource growth potential, both locally in MU2 and RA12, and throughout the Lost Creek Property.

Our preparations at Lost Creek have not been limited to drilling and construction. Operations staff continue to perform maintenance on plant equipment to ensure readiness for budgeted production levels. These efforts have progressed steadily because of the qualifications of our existing staff and the addition of new operating and management staff who are extremely qualified to move Lost Creek back to commercial production. Work includes inspection of operating equipment, vessels and tanks with maintenance occurring as required. Staff continue to cross-train in all plant operating practices in preparation for regular production.

We are also pleased to report on the progress of our centralized construction and laboratory facility. Ground was broken last year on the 6,000 square foot building adjacent to our Casper office building that will house separate areas for prefabrication of header houses and piping and a centralized chemistry laboratory to serve current and future Wyoming operations. The construction facility will allow us to efficiently fabricate header houses and transport them to the production site for timely installation. Because the facility is in Casper, significant savings will be realized from reduced travel and transportation of individual components. The laboratory will utilize the same concept to perform all the necessary measurements required at an in-situ uranium facility without lab staff commuting daily. Instead, site employees will transport materials to the lab. The facility is expected to be ready to support Lost Creek operations in May 2023 and will serve Shirley Basin and other Company production sites in the future.

Steve Hatten, the Company's COO, stated, "I am so proud to be associated with the hard-working and capable employees at our Company. They are working tirelessly to be able to move to renewed, elevated production that will supply our nuclear fuel customers for years to come. I am also excited that America has begun to realize the real 'green' value of nuclear energy as well as supporting its importance in energy security. We look forward to continuing to be a proven, front-line provider in the nuclear energy supply chain."

The Company is well financed with $79.0 million in cash as of March 1, 2023. We have sufficient conversion facility inventory on hand to meet our 2023 delivery commitments and anticipate selling a total of 280,000 pounds U₃O₈ at an average price of $61.89 for proceeds of $17.3 million in 2023.

Beyond our flagship Lost Creek Project, our second planned production site, Shirley Basin, has received all permits and licenses required to construct and operate the one million pound per year wellfield and two million pound per year processing plant. A decision to build out the Shirley Basin Project will be predicated on additional long-term sales contracts. We expect operating costs at Shirley Basin to be lower than those seen to date at Lost Creek due to shallow depth of the mineral, historical completion of extensive drilling, and significant existing infrastructure. For now, our planned installation of the monitor well ring for the first mine unit at Shirley Basin has been temporarily deferred due to the Wyoming winter and higher priorities at Lost Creek.
