Ur-Energy Begins Production Operations at Lost Creek

LITTLETON, Aug. 2, 2013 - Ur-Energy Inc. (TSX:URE, NYSE MKT:URG) ("Ur-Energy" or the "Company") is proud to announce that uranium production activities were initiated at its wholly-owned Lost Creek in-situ recovery project in south-central Wyoming on Friday August 2, after receiving notice of final operational clearance from the U.S. Nuclear Regulatory Commission.

Wayne Heili, President and CEO, stated, "Today marks a seminal moment in the history of Ur-Energy. Since the Company's formation in 2004, our investors, management and staff have held persistently to the goal of creating economic growth opportunities through the identification, development and production of quality uranium deposits. We are excited to initiate production operations for the Company at our flagship Lost Creek Project, marking the successful conclusion of eight years of development, regulatory and construction activities. Ur-Energy takes our responsibility to the environment, the public and our shareholders seriously, and our team is committed to diligently advancing the project. I have nothing but praise for the Company's management and staff whose talents, energy and dedication have made this milestone possible, and who will continue to make Ur-Energy successful in the years to come.

Construction of the project facilities was fully authorized in October 2012. The Company engaged Wyoming-based general contractor Groathouse Construction for the build-out of the plant and other infrastructure facilities. Since inception, Ur-Energy has invested over US$95 million in the acquisition, licensing and development of the Lost Creek Project.

Lost Creek currently employs approximately 60 full time workers. During production an additional 40 contract workers will be employed on site. The Company holds long-term sales contracts with several U.S. based nuclear utility companies, into which Lost Creek will make deliveries commencing in fourth quarter, 2013. The uranium produced at the Lost Creek Project will ultimately become the fuel that provides clean energy for the nation's power grid.
