Mesa Uranium Changes Name to Mesa Exploration

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 29, 2011) - Mesa Uranium Corp. (TSX VENTURE:MSA)(PINK SHEETS:MSAJF) has changed its name to Mesa Exploration Corp. ("Mesa" or the "Company") effective March 30, 2011. The name change has been accepted by the TSX Venture Exchange and approved by Mesa's board of directors.
