President’s U.S. Nuclear Fuel Working Group Releases

Plan to Revitalize the Domestic Uranium Mining Industry

Littleton, Colorado (PR Newswire – April 23, 2020) Ur-Energy Inc. (NYSE American:URG) (TSX:URE) (“Ur-Energy”)

is pleased to announce that t he United States Nuclear Fuel Working Group (“NFWG”) established by President

Trump released its report today detailing the steps required to revitalize the domestic uranium mining and

broader nuclear industries.

In January 2018, the two legitimate remaining U.S. domestic uranium producers, Ur-Energy USA Inc. and Energy

Fuels Resources (USA) Inc., filed a Section 232 Petition with the Department of Commerce seeking an investigation

into the impact of uranium imports on national security. As a direct result of th e ensuing investigation, in July

2019, President Trump took action to establish the NFWG to “examine the current state of domestic nuclear fuel

production to reinvigorate the entire nuclear fuel supply chain . . ..” The most relevant recommendations in the

report for the uranium mining sector are:

• Beginning in 2020, the U.S. government should make direct purchases of 17 to 19 million total pounds of U3O8

to establish a uranium reserve. These purchases would provide direct support to the front end of the fuel cycle

and help re-establish our nation’s critical capabilities.

• As included in the President’s Fiscal Year 2021 Budget Request, during the first year, it is expected that the reserve

would directly support the operation of at least two U.S. uranium mines and the reestablishment of active

domestic conversion capabilities.

• Restart the U.S.’s sole conversion plant beginning no later than 2022 and produce 6,000 to 7,500 tons of UF6.

• Restart domestic enrichment in the 2023 timeframe with at least 25% of material being unobligated. By law,

unobligated material must be sourced domestically.

• Support the Department of Commerce’s efforts to extend the Russian Suspension Agreement to protect against

future uranium dumping. The government should consider lowering the cap on Russian imports.

• Create a level playing field for all energy sources in power markets and encourage FERC to improve competition

in the wholesale energy markets.

• Enable the NRC to deny imports of nuclear fuel fabricated in Russia or China for national security purposes.

Ur-Energy’s Chairman and CEO Jeff Klenda stated, “We are grateful for the President’s leadership on this matter

and are excited to see the results of the NFWG’s holistic review of the entire industry . As the NFWG’s

recommendations are implemented, we will enjoy a revita lized nuclear industry and , consequently, a reduced

reliance on nuclear imports from our nation’s geostrategic rivals. While awaiting today’s report, we have

maintained operational readiness at our fully-permitted Lost Creek Mine with experienced technical and

operational staff and a well-maintained plant. More than six and a half years into production at Lost Creek, we are

still producing in the first mine unit and the initial three header houses of the second mine unit. Ur-Energy is

prepared to rapidly expand uranium production at Lost Creek , to an annual ized runrate of one million pounds.

And, soon we will add production from our Shirley Basin Mine.”

As discussed in our operational update from April 20, 2020, Ur-Energy continues production operations at its Lost

Creek uranium in-situ recovery project in south-central Wyoming. At this time, the COVID-19 pandemic has caused

- 2 -

no interruption of our production operations at Lost Creek . We have taken additional safety precautions as

directed by the government and health officials, and are able to report that our workforce remains healthy. The

Lost Creek facility has the constructed and licensed capacity to produce up to two million pounds of U3O8 per year

and the previously-reported mineral resources to feed th e processing plant for many years to come . A ramp-up

of production at Lost Creek will continue with further development in the fully -permitted first two mine units ,

where there are an estimated 4.3 million pounds U3O8 (Measured (2.9Mlbs) and Indicated (1.4Mlbs) categories)

remaining, and thereafter into ten additional mining areas as defined in the Lost Creek Property Preliminary

Economic Assessment, as amended, which together hold an added 7.13 million pounds Measured (3.68Mlbs) and

Indicated (3.46Mlbs) U3O8 and 3.9 million pounds U3O8 characterized as Inferred.

With future development and construction in mind, our current staff members were retained as having the

greatest level of experience and adaptability allowing for an easier transition back to full operations. Lost Creek

operations c an increase to full production rates in as little as six months following a go decision , simply by

developing additional header houses within the fully permitted MU2. Development expenses during this time are

estimated to be approximately $14 million and are almost entirely related to MU2 drilling and header house

construction costs. Lost Creek does not require any significant capital expenditures in order to increase

production. After the initial development expenditures, revenues from new appropriately-priced contracts should

cover further development activities. The Lost Creek plant has been routinely maintained to be fully ready to

receive additional flows for increased production when warranted. This operating strategy will allow us to control

production costs, minimize development expenditures, maximize cash flows and maintain the operational

flexibility to respond to market conditio ns. We are therefore better positioned, with lower ramp-up costs – and

less associated dilution – than other uranium recovery operators or the build-out stories which are prevalent in

our depressed market.

Our Shirley Basin project, with certain licenses and authorizations in place and all others expected by mid-summer

2020, has a reported mineral resource of nearly 9 million pounds U 3O8 in Measured (7.5Mlbs) and Indicated

(1.3Mlbs) categories, as set forth in the Shirley Basin Preliminary Economic Assessment.

As we are able to further review the report and learn specifics about implementation, we will provide additional

updates as appropriate.

NI 43-101 Review of Technical Information: Michael Mellin, Ur-Energy Lost Creek Mine Geologist, P.Geo. and
