DENVER, COLORADO -- (MARKETWIRE) -- 06/25/07 -- Ur-Energy Inc (TSX: URE) ("Ur-Energy" or "the Company") has entered into agreements with Trigon Uranium Corporation ("Trigon") to form the Hauber Project LLC ("Project").

Ur-Energy will contribute to the Project its recently acquired property located in Crook County, Wyoming, consisting of 205 unpatented lode mining claims and 1 state uranium lease totaling approximately 5,160 mineral acres.
