Ur-Energy Provides 2023 Q4/YE Operations Update

Littleton, Colorado (ACCESSWIRE – January 29, 2024) 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 n ew production

areas and recommissioning plant operations, not unexpectedly, come with unique start-up issues. The recovery

of U 3O8 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. O ur 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, w e 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 long er 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.
