Ur-Energy Provides Operations, Construction and 2024 Guidance Updates

Littleton, Colorado (ACCESSWIRE – September 18, 2024) Ur-Energy Inc. (NYSE American:URG) (TSX:URE)

(the “Company” or “Ur -Energy”) provides the following updates on Lost Creek Mine operations and

Shirley Basin construction, as well as updated production guidance.

Lost Creek Production Operations

Ramp up continues at Lost Creek with five header houses coming online in 2024. Most recently, Header

House (HH) 2-10 came online in mid-August, as scheduled, and HH2-11 is expected to come online this

month. Average production solution headgrade in August was 67.1 mg/L. Our fifth shipment of

yellowcake this year arrived at the conversio n facility on September 11 , and we are planning our next

shipment of dried product for late September. Deep disposal well #5 was recently placed into operation

and is satisfying wastewater needs.

We now have 15 drill rigs on site with additional drill rigs pending (not including three rigs at our Shirley

Basin Project). As we are able to grow the space between wellfield construction and drilling, we plan to

ultimately redirect some of the drill rigs to exploration projects within the Great Divide Basin with the

goal of replacing mined pounds with new uranium resources.

We continue to focus on employee training and retention as these are currently our most notable

challenges because many of our employees have little experience with uranium production. Our quality

workforce is, however, stabilizing.

Every month of 2024, except for June, we have steadily increased the pounds captured in the processing

plant. The Lost Creek wellfield is performing as expected and the issues which have slowed ramp-up are

temporary in nature. While ramp up continues to move in the right direction, it has been slower than

anticipated largely due to manpower matters. Therefore, we are revising our 2024 production guidance

to a range of 325,000 to 475 ,000 pounds of U 3O8 captured. We expect to satisfy our contractual

commitments to our customers with Lost Creek production and available alternatives.

Shirley Basin Development

Installation of the monitor wells for the first mine unit at Shirley Basin is on schedule with 120 of the 120

planned wells piloted and cased. We expect to finalize well completions in the coming days. We currently

have three drill rigs working at Shirley Basin, which will redeploy to Lost Creek when the completion

work concludes.

Plans are being finalized to collect baseline water quality and perform hydrologic aquifer tests this fall.

Power supply to the satellite plant construction area has been completed and the line is energized. The

access road upgrades are complete, and the septic system is being installed. Construction of fifteen IX

columns is on target with delivery expected in Q 3 2025. Our p urchasing program for equipment

continues, with an emphasis on continually reviewing the timing for long lead -time purchases such as

electronic components.

We continue to expect construction at Shirley Basin to be complete in late 2025 with a pre -operations

inspection by the State of Wyoming following soon after.
