Mesa Exploration Update by 24hgold

Re: News Releases - Thursday, December 17, 2009
Title: Mesa Uranium Green Energy Lithium Project Update

Mesa Uranium Corp. (TSX: MSA) announces results from data compilation of brine chemistry and reservoir characteristics at the Green Energy lithium project in Utah. The project consists of mining claims covering an area of approximately 10 square miles (6,000 acres) and is wholly-owned.

Lithium occurs at the project with values as high as 1,700 ppm lithium (0.9% Li2CO3) in saturated brine. Brine (40% minerals, 60% water) was discovered in the 1960s when oil exploration wells unexpectedly encountered high-pressure brine blow-outs upon drilling into Bed #31 of the Paradox Formation. Bed #31 is approximately 6,000 feet deep and consists of 30 feet of shale, anhydrite and dolomite; the bed is not part of any oil reservoir. Engineering reports from the 1960s conclude that the brine reservoir is extensive (over 10 square miles) and is recharged from fresh in-flows as indicated by well pressure measurements, drawdown tests and oxygen-deuterium isotopes. A professional engineering firm will be engaged to further evaluate historic and recent drilling data, reservoir potential and extraction methods at the project.

In addition to lithium, analytical data from historic drilling shows potentially valuable minerals were encountered. Below is a summary of this data:

Well Name	Boron (ppm)	Bromine (ppm)	Potash (KCl)	Magnesium (MgCl2)
BR 74-11	NA	NA	4.3%	15.3%
SNG No.1	NA	6,100	4.5%	17.8%
KO No.2	810	1,150	7.9%	18.7%
PO No.1	1,260	1,612	4.9%	12.3%
BF No.2	780	2,041	4.0%	13.0%

Potash is reserved under the Bureau of Land Management solid mineral lease program which Mesa has applied for as part of the White Cloud potash project encompassing the Green Energy lithium project. The White Cloud potash project is described on the Mesa website.

As previously reported, over twenty historic oil wells have been drilled on the Green Energy project; five of these wells have analytical data for lithium, below is a summary of this data:

Well Name	Lithium (ppm)	Gallons Per Day	Li2CO3 Annual Tons
WC No.2	1,700	491,000	8,786
SNG No.1	500	Adjacent to WC No.2	Not Determined
KO No.2	173	3 Miles North of PO No.1	Not Determined
PO No.1	134	1,356,000	1,911
BF No.2	81	50,400	43

Lithium brine mines are more economic to mine and process than conventional open-pit or underground mines. Given the favorable climate of the area solar evaporation can be used to concentrate the brine to enhance project economics. World-class lithium brine mines range in grade from 150 ppm to 1,200 ppm lithium and employ proven solar evaporation concentration techniques. High demand and low supply has pushed lithium carbonate (Li2CO3) prices to US$6,600.00 per ton, lithium-ion battery demand for hybrid-electric and electric cars is expected to increase significantly.

While the Company has no reason to doubt the accuracy of the historical results, the data should not be relied upon until confirmed by the Company's own exploration. Historical results and the work that generated them predate the enactment of National Instrument 43-101 and accordingly may not meet the requirements of that policy. There are no 43-101 mineral reserves or mineral resources on the Green Energy lithium project.

All statements in this release, other than statements of historical facts, including the likelihood of commercial mining and possible future financings are forward-looking statements. Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Factors that could cause actual results to differ materially from those in forward-looking statements include unsuccessful exploration results, changes in metals prices, changes in the availability of funding for mineral exploration, unanticipated changes in key management personnel and general economic conditions. Mining is an inherently risky business. Accordingly the actual events may differ materially from those projected in the forward-looking statements.
