Title: Mesa Uranium Acquires Additional Potash Projects in Utah

Mesa Uranium Corp. ("Mesa") (TSX-V MSA) is pleased to announce that its potash exploration permit applications have passed a Suitability Review at the Bureau of Land Management (BLM) District Office. The White Cloud potash project has been expanded to 35,510 acres and applications have been filed for two new projects, Salt Wash at 21,184 acres and Whipsaw with 17,968 acres. A total of 74,662 acres (116 square miles) of Mesa applications have passed BLM Suitability Reviews. The BLM state office will now process the applications and request a detailed exploration plan for each application from Mesa. Upon approval of Mesa's exploration plans, Exploration Permits will be issued.

Mesa's projects have excellent potential for potash production from both solution mining and artesian brine that is supersaturated (>40% solids) with potassium, magnesium, lithium, bromine and other minerals with potential commercial implications. In artesian wells groundwater flows upward through a well without the need for pumping. The projects are close to rail, interstate highway, natural gas pipelines and power lines.

The projects are located in southeastern Utah within the Paradox Basin, a geologic province known to contain potash deposits and mineral-rich artesian brines. The United States Geological Survey and Utah Geological Survey have documented these occurrences in various reports and the projects are within an area categorized as a high "known mineral deposit area" for potash beds by the U.S. Bureau of Mines.

Just 1.5 miles to the south of the White Cloud project, Intrepid Potash's Cane Creek potash mine produces approximately 80,000 tons of potash and 100,000 tons of by-product salt annually. Potash is produced by solution mining and solar evaporation from potash beds #5 and #9 at depths of 3,000 to 4,500 feet. The mine has been in production for over 40 years.

Initial oil exploration wells drilled in the 1950s and 1960s at the White Cloud project experienced free flowing (artesian) blow-outs when they unexpectedly drilled into super-saturated brines. At the White Cloud project over half of the 55 square mile property has been drilled for oil, and the historic oil well logs show that potash beds #5, #9 and mineral-rich artesian brine aquifers underlie the project. Mesa is reviewing reports and radiometric logs from historic oil drilling to assess grade, thickness, and depth of the potash beds as well as grade and flow rates for the brines.

Historic analyses of brine samples from oil wells drilled on the White Cloud project indicate commercial grades of potassium, magnesium, lithium, bromine and other minerals:

Historic Oil Well	Potassium Chloride Percent	Magnesium Chloride Percent	Lithium PPM	Bromine PPM
King Oil No. 2	8.0	18.7	173	1,150
Pure Oil No. 2	4.0	13.0	81	2,041
Roberts Brine Well	6.3	13.3	1,700	2,500
Southern Natural #1	4.4	17.8	500	6,100
Tidewater 74 -11	4.3	15.3	NA	NA

For reference, grades at commercial potash brine operations around the world range from 0.5 to 2.0% potassium chloride and commercial lithium brine operations grade ranges from 200 PPM to 1,500 PPM.

Oil and gas wells located within the White Cloud project area have penetrated the potash beds and brine at depths of 4,700 to 7,400 feet. Brine flow rates ranging from 3,600 to 11,700 barrels per day have been measured from historic oil wells. If found to be persistent the brine could provide sufficient production without the need for injection and production wells and pumps as used in traditional potash solution mines.

At the Salt Wash project oil and gas wells penetrated the potash beds and brine at depths of 3,500 to 8,600 feet and 1,500 to 7,000 feet at the Whipsaw project. Mesa is in the initial stages of reviewing data from these two projects.

About Potash
Potash (K2O potassium oxide) is a fertilizer essential to plant nutrition and is critical to modern agriculture. A growing world population is accelerating the need for higher crop yields, leading to massive growth in demand. Potash demand is reflected in the price trend, with prices increasing from $100 per ton in 2000 to over $700 per ton in 2009. The United States is the world's largest consumer of potash and imports over 80% of its requirements.

About Mesa Uranium
Mesa is a mineral exploration company focused on uranium and potash in the western United States. Mesa has 100% ownership of 46 square miles of uranium exploration lands in the Lisbon Valley Mining District in Utah and the Arizona Strip Mining District in northern Arizona and 116 square miles of potash exploration applications in Utah.
