Ur-Energy Provides 2023 Q4/YE Operations Update

Ur-Energy Inc. (NYSE American:URG)(TSX:URE) ("Ur-Energy" or the "Company") is pleased to provide the following update on 2023 Q4 and Year-end uranium sales and production operations at Lost Creek

Lost Creek Production Operations

Ramp-up at Lost Creek in 2023 led to operation of the first two new header houses in Mine Unit 2 (MU2). Our Q4 production figures reflect the progress made in wellfield operations: in 2023, we captured approximately 103,487 pounds U₃O₈, of which 68,448 pounds U₃O₈ were captured in Q4. The average production grade in Q4 was 93.9 mg/l.

Wellfield development continues with header house-specific wells being completed. All delineation drilling throughout the remaining eight planned production areas in MU2 is finished. We have 11 drill rigs onsite with plans to mobilize additional rigs in the coming weeks.

As previously disclosed, the restart at Lost Creek encountered challenges. Commissioning new production areas and recommissioning plant operations, not unexpectedly, come with unique start-up issues. The recovery of U₃O₈ in MU2 and the restart of plant operations have been no exception. As the plant was being recommissioned, we encountered equipment issues that temporarily reduced plant throughput. The equipment issues have been or are being addressed, and plant operations will be returning to anticipated production rates.

The staffing of Lost Creek's current 65+ onsite positions is complete, and we are experiencing greater retention, which fosters more thorough training. We are seeing steady improvement in production activities as our growing core staff have more time on the job. The Wyoming labor market has similarly affected our contractors. Certain labor and contractor/vendor challenges may continue.

While the record-setting winter of 2022-2023 is behind us, the ways in which it affected our recruitment, training and restart of operations continue to be felt, but are being overcome. More positively, conditions to date this winter have permitted construction and development activities to progress without significant hindrance or weather delay.

We have benefitted from our advance ordering and recycling of equipment at Lost Creek while supply chain disruption continues to be a global industry issue. We will continue to order equipment and materials well in advance and remain aware of fluctuating lead times for critical items.

John Cash, Ur-Energy's CEO and Chairman of the Board stated, "The world has finally recognized the critical role nuclear energy plays in providing baseload power to support energy security and decarbonization goals. We are pleased to be one of the few publicly traded companies that is commercially mining uranium and expanding our production capacity to sell into a rapidly expanding market. The foresight of our directors and years of hard work by our staff have put us in this unique position and we are excited to continue advancing production in the great State of Wyoming."

Sales of Uranium and Sales Agreements

During 2023, we sold 280,000 pounds U₃O₈ from existing inventory for $17.3 million. At December 31, 2023, we had cash and cash equivalents of $59.7 million. Our sales in 2024 are projected at 570,000 pounds U₃O₈ into contracts that were put in place in 2022 when the long-term price was well below $60 per pound. We look forward to delivering our product into these commitments from existing inventory and new production.

As disclosed in Q4, we are advancing agreements to signature with three companies in the global nuclear industry for additional sales commitments over a five-year period beginning in 2026, with an option under one agreement for the buyer to extend its purchase commitments for three additional years, until 2033. (See October 19, 2023 Ur-Energy News Release).

Shirley Basin Project

As announced in October 2023, we are advancing Shirley Basin toward construction and operations. While a "go" decision has not been made, procurement of long-lead items for the Shirley Basin Project has been initiated and detailed planning for other development and construction activities is in progress. We currently estimate it will take approximately 24 months to complete procurement, development, and construction activities of the satellite facility and its associated first mine unit to initiate production following a "go" decision. This estimate is based on the longer lead times we are seeing for critical equipment; especially for electrical equipment. Shirley Basin is fully permitted and construction ready with a licensed wellfield capacity of one million pounds U₃O₈ per year.
