Ur-Energy Prepays Promissory Note

DENVER, COLORADO -- (MARKETWIRE) -- 06/07/07 -- Ur-Energy Inc. (TSX: URE) (the "Company") is pleased to announce that it has fully paid the promissory note due to New Frontiers Uranium, LLC ("New Frontiers") saving the Company US$3.75 million in future interest charges.

The promissory note obligation arose in conjunction with the Membership Interest Purchase Agreement ("MIPA") entered into with New Frontiers effective June 30, 2005. Under the terms of the MIPA, Ur-Energy USA purchased 100% of the issued and outstanding membership interests in NFU Wyoming, LLC ("NFU Wyoming") which owned certain Wyoming properties in the Great Divide Basin and Shirley Basins. In total, the property ownership comprised 99 unpatented mineral claims and mineral leases on three state sections. The assets acquired from New Frontiers included the extensively explored and drilled Lost Creek and Lost Soldier projects and a development database including over 10,000 electric well logs, over 100 geologic reports and over 1,000 geologic and uranium maps covering large areas of Wyoming, Montana and South Dakota.

The aggregate consideration payable under the terms of the MIPA was US$20,000,000. The total amount payable on closing was US$5,000,000. The balance of the acquisition cost was financed by way of the promissory note payable to New Frontiers. In June of 2006, the Company made the first anniversary payment of US$5,000,000. The Company has elected to prepay the amount outstanding prior to the second anniversary on June 30, 2007 with an adjustment in the interest due and payable.

Roger Smith, CFO, stated, "Not only does the early retirement of the debt save the Company US$3.75 million of interest charges, but it also demonstrates management's continued commitment to, and confidence in, our Lost Creek and Lost Soldier projects in the Great Divide Basin of Wyoming. This allows us to focus our undivided attention on the development of these and other projects from a debt-free position."

Under the terms of the MIPA, the Company through NFU Wyoming staked 211 additional unpatented mineral claims for the Bootheel and Buckpoint projects within the Shirley Basin, Wyoming. Within the Great Divide Basin, Wyoming, the Company staked 117 additional unpatented mineral claims in the North Hadsell project area, 133 additional unpatented mineral claims in the Lost Creek projects area and 17 additional unpatented mineral claims in the Lost Soldier project area.

"We're very pleased to complete our payment to New Frontiers two years earlier than required by our agreement," commented CEO & President Bill Boberg. "The principals of New Frontiers, Fred Groth, Dick Fruchey and Tom Pool, have been excellent to work with over the past two years, and I look forward to continuing our association in the future. We are delighted that they had the foresight, long before this current uranium bull market started, to acquire the uranium projects and databases that formed the basis of our agreement with them back in 2005. The projects and databases that we acquired from them have led to a major part of our growth."
