Ur-Energy Delayed in Exploration at its Screech Lake Property

DENVER, COLORADO -- (MARKET WIRE) -- 05/09/07 -- Ur-Energy Inc. (TSX: URE)("Ur-Energy" or the "Company") reports that the Mackenzie Valley Environmental Impact Review Board (the "Review Board") has recommended to the Minister of Indian and Northern Affairs Canada that the Company's application to conduct an exploratory drilling program at the Company's Screech Lake property be rejected pursuant to section 128(1)(d) of the Mackenzie Valley Resource Management Act. This section of the Act sets out that the Review Board shall, "Where the development is likely in its opinion to cause an adverse impact on the environment so significant that it cannot be justified, recommend that the proposal be rejected without an environmental impact review".

Ur-Energy is disappointed by the Review Board's recommendation and is assessing its options for pursuing its proposed exploration program at the Screech Lake property. The Company also plans to discuss the Board's recommendation with the Minister of Indian and Northern Affairs Canada. The Company believes that it has proposed an exploration program which maintains the highest possible environmental standards. In the Company's application for a land use permit, extensive mitigation measures were proposed to ensure that the drilling program would have minimal short-term environmental impact and no long-term effect.

Bill Boberg, President and CEO, states "We are disappointed by the Review Board's recommendation and will continue to pursue any and all approaches that will allow us to advance exploration on the project as soon as possible. Screech Lake is an early stage exploration project and this delay in our exploration at Screech Lake does not affect our exploration and development activities in other areas. In Wyoming, we continue on schedule to move our Lost Creek and Lost Soldier projects toward production".

Ur-Energy is a junior mining company completing mine planning, baseline studies and permitting activities to bring two uranium deposits in Wyoming into production. The Company is also engaged in the identification, acquisition and exploration of uranium properties in both Canada and the United States. Shares of the corporation trade on the Toronto Stock Exchange under the symbol URE. Ur-Energy has a registered corporate office in Ottawa, Canada and bases its headquarters in Littleton, Colorado.
