Six Drill Rigs Turning for Ur-Energy

DENVER, COLORADO -- (MARKET WIRE) -- 05/08/08 -- Ur-Energy Inc (TSX: URE) ("Ur-Energy" or "Corporation") began drilling yesterday at the Lost Creek Wyoming project with three drill rigs. Three additional drill rigs started today. The 2008 scope of activities at Lost Creek involves approximately 485 drill holes as described below:

- Delineation and exploration drilling of 400 drill holes to determine the extent of minable uranium resources and to locate potential extensions. Hole depths will generally range from 650 to 1,000 feet.

- Installation of a series of 84 cased Monitor Wells mostly surrounding and within the first proposed mining wellfield unit. These wells will be maintained long-term and will eventually be utilized during the production phase. Average depths will be approximately 50 feet. These wells will be used to test the hydrologic characteristics of the formation and for future groundwater quality monitoring.

- One water supply well will be drilled with a total depth estimated to be 1,000 feet.

Drilling density will vary from 100 foot to 2,000 foot spacing. Approximately 300 delineation holes and 85 wells will be drilled on close spacing within the area of the mineral deposit. 100 holes will be drilled as exploration drilling on wider spacing throughout the Lost Creek Project area. All exploration holes will be plugged and permanently abandoned, and all wells will be cased in a timely manner in accordance with WDEQ guidelines and regulations. Two geophysical logging units are also on-site working along with Ur-Energy's PFN logging truck.

Wayne Heili, VP Mining, noted, "The URE staff has been working diligently to plan this year's field program. Each planned activity is designed to contribute directly toward the overall objective of placing the Lost Creek deposit into production. It is rewarding to see the commencement of work following the concentrated effort of the Ur-Energy team."
