Ur-Energy Advances Growth Portfolio in the Great Divide Basin

Technical Studies Underway on Lost Soldier Project

North Hadsell Drilling Returns Significant Intercepts

CASPER, WY / ACCESS Newswire / January 28, 2026 / Ur-Energy Inc. (NYSE American:URG)(TSX:URE) (the "Company" or "Ur-Energy"), a U.S. producer of uranium, is pleased to provide an update on work at its Lost Soldier and North Hadsell Projects, located in the Great Divide Basin, Wyoming.

Ur-Energy is off to a strong start in 2026 at both the Lost Soldier and North Hadsell Projects, delivering encouraging results in our work programs that demonstrate the upside potential of these assets. The objectives of our drilling were straightforward and value-driven: first, to gather critical hydrogeologic data at Lost Soldier to reduce risk and support efficient planning and permitting, and second, to identify new uranium roll-front targets at North Hadsell.

Both projects are located near our producing Lost Creek uranium mine, providing increased potential to leverage existing infrastructure, reduce future development capital requirements, and expand our uranium mineral resource base in Wyoming's prolific Great Divide Basin.

Highlights

Lost Soldier Project

• Strategic Proximity to Operations: Lost Soldier is a 17-mile drive from the Company's producing Lost Creek ISR mine and processing facility, which may enable capital-efficient development by leveraging established infrastructure and operating expertise.

North Hadsell Project

• Project Scale: Two of the most compelling holes exhibit this stacked roll-front mineralization at similar depth horizons and are located approximately 1.5 miles apart, indicating the potential scale of the mineralized system.

Ur-Energy CEO and President, Matthew Gili, commented: "The early success at North Hadsell, combined with our decision to advance technical studies and hydrogeologic work at Lost Soldier, underscores the momentum we are building across our Wyoming growth portfolio. As this work progresses, we see meaningful potential for capital-efficient resource expansion, strengthening Ur-Energy's long-term development pipeline."

Lost Soldier Project

Located approximately 17 miles (27 kilometers) to the northeast of Lost Creek, Lost Soldier has approximately 4,000 historic drill holes defining 14 mineralized sandstone horizons within the lower Battle Spring Formation. We control 105 unpatented mining claims at the property, totaling approximately 1,960 mineral acres.

Recent drilling at Lost Soldier focused on installing 18 aquifer test wells to enhance our understanding of the local hydrogeology. While the geology of the project area is well understood, this additional hydrogeologic characterization will assist our technical teams in optimizing planning, permitting, and potential development activities. Aquifer testing is anticipated to begin in Q1 2026.

Work is also underway to complete a new technical report with the goal of establishing a mineral resource estimate based on detailed roll-front mapping. The new report will combine results from recent work and historical data to produce a mineral resource estimate to facilitate assessment and planning for potential ISR development. The technical report on Lost Soldier is expected to be completed later this year.

North Hadsell Project

The North Hadsell Project is located approximately three miles west of Lost Soldier and 10 miles north of Lost Creek and includes 203 unpatented mining claims covering about 3,970 mineral acres. The Project is underlain by the same uranium-bearing geologic formation as Lost Soldier and Lost Creek. While some historical drilling is known in the area, the related data are largely unavailable.

We commenced a 50-hole drill program in Q4 2025 and have completed 16 wide-spaced framework holes, each approximately 1,000 feet deep, for a total footage of 16,765 feet. Five of these initial drill holes have returned significant mineralization, indicating the presence of a stacked roll-front system containing 11 individual intercepts greater than 0.20 GT (Grade (%eU₃O₈) times Thickness (ft)). These grades and thicknesses closely resemble the mineralization at Lost Creek, where the Company applies a 0.20 GT cut-off in evaluating economic mineral resources. Preliminary interpretation suggests the potential for up to eight individual roll fronts within a depth range of approximately 300 to 800 feet below surface, ideal for ISR mining, with indications of additional mineralized horizons at depth. Notably, the two most encouraging drill holes to date are located more than 1.5 miles apart with mineralization in similar horizons, suggesting the Project's scalability and resource potential.

Drilling will continue until the 50-hole program is completed or until March 15, when seasonal sage grouse restrictions begin. Any remaining work should resume in the summer.
