Mesa Exploration Bounty Potash update

VANCOUVER, BRITISH COLUMBIA–(Marketwire – May 9, 2012) – Mesa Exploration Corp. (TSX VENTURE:MSA)(PINKSHEETS:MSAJF) ("Mesa") announces an update on progress at the 100% owned Bounty Potash Project in the Great Salt Lake Desert of western Utah. Dr. Wallace Gwynn, a saline brine expert recently retired from the Utah Geological Survey, has provide to Mesa a summary report on various aspects of the Bounty Potash Project. Dr. Gwynn has an intimate knowledge of the potash production from brine in the Great Salt Lake Desert and the Great Salt Lake of western Utah.

The report by Dr. Gwynn documents previous work completed at the project, summarizing aquifer recharge and discharge, brine concentrations, chemistry and provisional extraction strategies. Historic brine chemistry is summarized as well as detailed climate data documenting recharge and evaporation rates useful in planning potential potash production. Preliminary exploration work and data collection plans in the report chart a path forward to develop the project with detailed reporting and exploration work to follow based upon this report.

A Utah-based drilling contractor with extensive local brine drilling experience has been engaged for the program. Cross Marine Projects Company has over 38 years of experience and has equipment specifically designed for working on salt flats and playas. Permitting is advancing with the expectation that drilling will commence this summer.

About the Bounty Potash Project

Historic exploration work at Bounty was conducted in 1966 by Quintana Petroleum. Quintana drilled 35 auger holes resulting in the definition of 5.1 million tons of potash (MOP) grading 6.8 grams/liter. Quintana limited the estimation of the resource to the top 10 feet of the brine aquifer, the depth limits of the auger drilling equipment; Mesa controls 80% of this resource. The Quintana resource is historical in nature and was calculated using a polygonal contour estimation method, the industry standard prior to NI 43-101 standards, thus it is not NI 43-101 compliant and should not be considered as a current resource.

The project is 15 miles north of Intrepid Potash's Wendover operation, a potash mine which is chemically and physically analogous to the deposit at the Bounty project. The Bounty project consists of 90 square miles of potash prospecting permit applications from the Bureau of Land Management (BLM) and 14 square miles of Potash Leases from the State of Utah. The Wendover mine has been in production for 75 years utilizing a system of potash brine collection ditches and solar evaporation ponds, with potash and salt being processed in a simple flotation mill. The Wendover mine has annual production of 100,000 tons of potash and 200,000 tons of magnesium chloride, grossing $60 million per year.

The Bounty project area is a remnant of a regional Pleistocene lake which deposited a salt flat underlain by a potash brine aquifer at depths of 2 to 6 feet. The aquifer is contained in a bed of sand, silt and clay. Several potash brine mines in the area are operating on similar lake remnants, producing muriate of potassium (MOP) and sulphate of potassium (SOP), at operating costs of $180 per ton. MOP sells for $500 per ton and SOP for $650 per ton.
