Title: Mesa Uranium Files 43-101 Report, Expands the Green Energy Project

March 23, 2011 - Mesa Uranium Corp. (TSX-V: MSA) ("Mesa" or the "Company") is pleased to report that it has filed a technical report under National Instrument 43-101 for the wholly owned Green Energy project in Utah. Additionally, Mesa has staked new claims contiguous to the existing claim block, adding 2,240 acres for a total position of 10,080 acres.

The Technical Report was prepared by Dana Durgin of Delve Consultants, a Reno Nevada based consulting geologist who fulfills the requirements of a 'Qualified Person' for the purposes of NI 43-101. The report is dated March 14, 2011 and is titled "Technical Report, Geology and Mineral Resources, Green Energy Project, Grand County, Utah". The report may be viewed on Mesa's website www.mesauranium.com or on the System for Electronic Document Analysis and Retrieval (SEDAR) www.sedar.com.

In the report, Mr. Durgin provides a detailed description of the historical reserve estimates, mineral potential, geology and previous exploration on the project. Mr. Durgin's review recommends a Phase 1 program of evaluation, drilling and metallurgical testing on the targeted areas, at an estimated budget of $340,000. An excerpt from the Recommendations section concludes: "The drilling of a well should be considered for exploration and possible production. It should be designed to sample the Clastic Zone 31 brine and the potash #5 and #9 strata, which are those currently being mined at Intrepid Minerals' Cane Creek potash mine". Mesa is currently engaged in obtaining the permits and selecting a drilling contractor for this program.

The report stated "While not yet sufficiently well defined for mining purposes, both the lithium and the potash resources appear to be quite large, based on the oil and gas well data, and on brine studies from the 1960's." Mesa is currently creating a 3-D model using the oil and gas well data to aid in drill target selection.

About the Green Energy Project
Mineral brine occurs at the project with historic values as high as 1,700 ppm lithium (0.9% Li2CO3), 7.9% potash, 18.7% magnesium chloride, 6,100 ppm bromine and 1,260 ppm boron; these results are not 43-101 compliant and have not been verified by the Company. To put the project into context, the table below shows lithium and potassium grades at various natural brine mines. Potash from solution mining typically grades 1-3% potash however, these are man-made brines created by dissolving concentrated bedded potash deposits.

Deposit	Location	Lithium (ppm)	Potash (percent)
Green Energy	Utah	81-1700	8.96
Atacama	Chili	1,700	4.2
Clayton Valley	Nevada	300	0.15
Great Salt Lake - North Arm	Utah	66	0.87
Great Salt Lake - South Arm	Utah	43	1.3
Hombre Muerto	Argentina	100-700
Uyuni	Bolivia	100-500
