Mesa Uranium Receives Drilling Permit at Moonshine Springs, Arizona

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 21, 2010) - Mesa Uranium Corp. (TSX VENTURE:MSA)(PINK SHEETS:MSAJF) ("Mesa") announces that it has received drill permits from the Arizona State Land Department at the 100%-owned Moonshine Springs project in Arizona. More than 9,800 feet of conventional and core drilling are planned, targeted at expanding previously drilled mineralization and new geochemical targets. The work is anticipated to begin this summer.

An extensive two phase radon soil gas survey has been completed and results portray a pattern of radon enrichment consistent with an elevated subsurface uranium source. Radon surveys led to the discovery of the adjacent Moonshine uranium deposit (4.67 million pounds grading 0.153% U3O8) owned by Denison Mines. The sandstone horizon that hosts this deposit was encountered in Mesa drilling, the best intercepts being 7.5 feet grading 0.21% U3O8 and 4 feet grading 0.47% U3O8, as previously reported.

Radon enrichments were found on the northern extension of the Moonshine uranium deposit, around Mesa drill holes M-1 and M-2 and on multiple areas with no previous drilling. A map depicting the results can be found at this link: http://www.mesauranium.com/i/maps/radon_map_from_alpha_track.jpg
