Mesa Initiates Permitting for Green Energy Lithium Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 20, 2010) - Mesa Uranium Corp. (TSX VENTURE:MSA) ("Mesa") is pleased to report that it has initiated the filing process to obtain drilling permits for the Green Energy lithium project in Utah. Mesa controls 7,850 acres or approximately 12 square miles, the project is wholly owned by Mesa.

Drilling Program

A Phase I drilling program is being designed to sample lithium-bearing brine for chemical analysis and metallurgical testing for mineral extraction. Engineering characteristics of the brine formation will also be tested to establish pressure, temperature, artesian characteristics and drawdown to aid in reservoir engineering and modeling.

Lithium occurs at the project with values as high as 1,700 ppm lithium (0.9% Li2CO3) in saturated brine. In addition to the lithium the brine grades as high as 7.9% potash, 18.7% magnesium chloride, 13% salt, 6,100 ppm bromine and 1,260 ppm boron.

The brine, 40% minerals and 60% water, was discovered in the 1960s when oil exploration wells unexpectedly encountered high-pressure brine blow-outs upon drilling into Bed #31 of the Paradox Formation. Bed #31 is approximately 6,000 feet deep and consists of 30 feet of shale, anhydrite and dolomite; the bed is not part of any oil reservoir.

While the Company has no reason to doubt the accuracy of the historical results, the data should not be relied upon until confirmed by the Company's own exploration that meet NI 43-101 standards for disclosure. Historical results and the work that generated them predate the enactment of National Instrument 43-101 and accordingly may not meet the requirements of that policy. There are no 43-101 mineral reserves or mineral resources on the Green Energy lithium project.
