VANCOUVER, B.C. - Magnum Uranium Corp. ("Magnum" or "the Company) is pleased to announce that it has entered into a Joint Venture Agreement with Triex Minerals Corporation ("Triex") under which Triex has the right to acquire up to a 70% interest in Magnum's Stony Road Property located in Canada's Athabasca Basin.

The Stony Road Property covers a total of 183,040 acres located in the northeastern part of the Athabasca Basin. Magnum's recently completed Megatem II Airborne Geophysical Survey delineated several anomalies within the Stony Road Property (see Magnum News Release dated September 5th, 2006). The Property covers approximately 45% of Magnum's land position in the Athabasca Basin.

Triex can earn an initial 60% joint venture interest in the property by incurring a cumulative total of $1,500,000 in exploration expenditures on or before April 30, 2009 and by making a cash payment of $25,000. Triex can increase its interest to 70% by incurring an additional $1,500,000 in exploration expenditures on the property by November 1, 2011 and by making further cash payment of $25,000.

Triex will advance the Stony Road Property based on the newly identified exploration at their Pasfield Lake property, and refined exploration model for the Cable Bay Shear Zone and associated magnetic features (see Triex News Release dated May 1, 2007). A $500,000 exploration program is being planned for this summer. Planned work includes a 3-D Full Tensor gravity gradient airborne survey to compliment the MEGATEM II airborne EM survey already completed by Magnum (see News Release dated Sept. 5th, 2006), a ground-based AMT survey (audio-magnetotellurics) which was effective at delineating the Pasfield Lake uplift feature and Cable Bay Shear Zone, and detailed geochemical surveys and prospecting.
