Ur‐Energy Confirms BLM EIS for Lost Creek and Lost Creek East 

Littleton, Colorado (PR Newswire – September 16, 2015) Ur‐Energy Inc. (NYSE MKT:URG, TSX:URE) (“Ur‐
Energy” or the “Company”) confirms the Bureau of Land Management’s (BLM) Notice of Intent To
Prepare an Environmental Impact Statement (EIS) for the Proposed Lost Creek Uranium In‐Situ Recovery
Project Amendments, Sweetwater County, WY.
The Amendment applications seek approval to:
‐ Recover uranium via the in situ technique from the KM Horizon in essentially the same footprint
as the previously‐approved Lost Creek Permit area. Increase the aerial extent of mining in the
permitted HJ Horizon.
‐ Recover uranium via the in situ technique from both the KM and HJ Horizons within the LC East
area, immediately adjacent to the permitted Lost Creek Project.
‐ Increase the overall production rate from 1.0 million pounds of U O to 1.2 million pounds of 3 8
U 0 per year from facility wellfields plus one million pounds of U 0 per year from toll milling 3 8 3 8
resin or slurry from other off‐site facilities. The resulting maximum production through the
existing processing facility would be 2.2 million pounds of U 0 per year (up to 1.2 million from 3 8
wellfields and up to 1.0 million from potential toll processing).
If approved, the proposed Amendment will increase the size of the facility to a total of approximately
642 acres which includes all existing and proposed facilities. The Amendment will allow continued
development and production of additional resources within the currently permitted Lost Creek Project
as well as the Lost Creek East area. The U.S. Nuclear Regulatory Commission plans to participate in the
NEPA process as a cooperating agency.
