Titan Uranium Inc.: Ur-Energy Discontinues R-Seven/Rook I Option

Saskatoon, Saskatchewan, Canada March 20, 2008 - Titan Uranium Inc., (“Titan” or the “Company”) (TSX-V: TUE) announces it has received formal notification from Ur-Energy Inc. (Ur-Energy) that Ur-Energy has elected not to continue its earn-in on the R-Seven/Rook I Option Agreement effective March 17th, 2008.

As per Titan’s March 3rd (2008) press release, the 75,698-hectare R-Seven and Rook I properties were the subject of a 14-hole (3213.4 metre) diamond drill program in the fall of 2007. Drilling intersected structural disruptions and alteration commonly associated with uranium mineralization. For most of the intervals assayed, uranium values were low or only slightly anomalous. However, one hole testing an offset of the main electromagnetic conductor did encounter elevated uranium values (up to 105 ppm U3O8).

Titan has scheduled additional geophysical surveys and follow-up diamond drilling for the R-Seven/Rook I properties in 2008. Additionally, the Company has expanded its land holdings in the area by staking four claims (13,894 hectares) along the south margin of the properties.

About Titan Uranium

Titan’s growth strategy is driven by advancing exploration projects to discovery in the proven Athabasca and prospective Thelon basins. The Company has gained market recognition for its ability to attract strategic partners to participate in exploration on its properties by virtue of its 1.5 million acre land position and technical expertise. Japan Oil, Gas and Metals National Corporation (JOGMEC) recently signed a letter of intent with Titan to explore the Virgin Trend Project in the Athabasca Basin. Additional partnerships are at the planning stage.

Titan is well-financed and ideally positioned to emerge as a pre-eminent explorer in the uranium industry. Based in Saskatoon, Saskatchewan, Titan boasts proven senior leadership, a highly experienced technical team and a dominant land position in Canada’s world-class uranium districts.
