VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 3, 2011) - Mesa Uranium Corp. (TSX VENTURE:MSA)(PINK SHEETS:MSAJF) ("Mesa" or the "Company") is pleased to announce that our joint venture partner Passport Potash Inc. ("Passport") has commenced a 50-line-mile seismic survey at the Holbrook basin site. The survey, being performed by Zonge International, will include the lands subject to a joint venture between Mesa and Passport. Passport is the operator of the joint venture; all exploration expenditures on the joint venture are paid by Passport.

The results of the seismic survey will be used in evaluating geologic, stratigraphic and structural information for the Holbrook basin, improving Passport's ability to assess the predictability, thickness and continuity of the potash horizon and the mapping of faults and other geologic structures within those rock units of primary interest. This information will be included and utilized in the NI 43-101 report being prepared by SRK Consulting for Passport.

Commenting on the seismic survey, Mesa President Foster Wilson stated: "Mesa is very pleased with Passports modern exploration strategy and their selection of first-rate contractors to advance the Holbrook basin potash deposits towards resource development."
