Mesa Drills 17.5 Feet Grading 0.11% U3O8

 Mesa Uranium Corp. ("Mesa") is pleased to report results from the ongoing 2007 drilling program at the 100%-owned Lisbon Valley uranium property in the Lisbon Valley Mining District of Southeastern Utah.

To date, the drilling program consists of seven holes drilled southeast of the Lisbon Mine. We are particularly excited about the results from drill holes L-15 and L-17. L-15 intercepted three strongly mineralized zones consisting of:

• 3.5 feet of 0.28% U3O8 (5.6 pounds/ton);
• 1.0 foot of 0.16% U3O8 (3.2 pounds/ton); and
• 1.5 feet of 0.13% U3O8 (2.6 pounds/ton).

Strong mineralization between these three higher-grade intercepts resulted in an overall mineralized interval of 17.5 feet grading 0.11% U3O8 (2.2 pounds/ton).

The mineralization in L-15 is similar to the material mined at the Lisbon Mine, the District's largest mine (22 million pounds of U3O8). L-17 was drilled 1,200 feet to the southeast of L-15 and intercepted 2.0 feet of 0.08% U308 in the same horizon with values of 0.02% U3O8 throughout the 15 feet horizon above the intercept. We are encouraged by the apparent lateral continuity of this strong mineralization between L-15 and L-17.

L-15 and L-17 were drilled over 8,000 feet east of the Lisbon Mine in an area that has had no previous exploration along Mesa's projected southeast to northwest trend. Offset drilling around L-15 to test the extent of this mineralization is planned to begin within two weeks.

Holes L-11, L-12, and L-13 were drilled southeast of the strong mineralization encountered in holes L-4 and L-7 last year (see news release dated 9/14/2006). All three holes encountered mineralization and Mesa is currently evaluating the geologic potential in this area. L-14 was drilled 2,000 feet further to the southeast and intercepted very favorable mineralization. We are currently evaluating the geologic potential around L-14.

Mesa has also drilled 2 holes in southern Lisbon Valley, and 1 hole at the North Alice target, assay results are pending and will be released once received.

Drill results are as follows, depths are to the base of mineralization:

Mesa currently controls 30 square miles of prospective ground in the Lisbon Valley Mining District and continues to expand its land position in the District. The current campaign of exploration drilling will continue to explore a number of highly prospective targets throughout the remainder of 2007.

All holes were logged by Jet West Geophysical Services of Farmington, New Mexico to produce a log suite of Gamma, Spontaneous Potential (SP), and Resistivity values. The Gamma portion of the down-hole logging tool was calibrated at uranium-industry standard pits located in Grand Junction, Colorado. In situ uranium grades, expressed as equivalent U3O8 (eU3O8) are calculated using the digital gamma ray values acquired by the down hole logging tool and uranium industry standard techniques for gamma log interpretation. Down-hole gamma log interpretation has historically been found to be an accurate representation of in situ grades for uranium mineralization in the Lisbon Valley District. Drilling was performed by Bob Beeman Drilling of Moab, Utah.
