Mesa Uranium Acquires Lithium Project

TSX Venture: MSA

VANCOUVER, Nov. 4 /PRNewswire-FirstCall/ - Mesa Uranium Corp. (TSX: MSA) is
pleased to announce that it has acquired, by staking, 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 100% wholly-owned. 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 fivefold by 2012.
Lithium occurs at the project over an extensive area with values as high as
1,700 ppm lithium (0.9% Li2CO3) in saturated brine. The brine was discovered
in the 1960s when oil exploration wells encountered blow-outs drilling into
Bed #31 of the Paradox Formation. The pressurized free-flowing brine
interrupted drilling operations and was considered a nuisance, rarely
chemically analyzed or flow-rate tested. Over twenty oil exploration 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:

-------------------------------------------------------------------------
Li2CO3 Annual
Well Name Lithium (ppm) Gallons Per Day Tons
-------------------------------------------------------------------------
WC #2 1,700 491,000 8,786
-------------------------------------------------------------------------
SNG #1 500 Adjacent to WC #2 Not Determined
-------------------------------------------------------------------------
KO #2 173 3 Miles North of PO #1 Not Determined
-------------------------------------------------------------------------
PO #1 134 1,356,000 1,911
-------------------------------------------------------------------------
BF #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.
Mesa is currently evaluating all available recent and historic exploration
drilling logs. A professional engineering firm will be engaged to evaluate
drilling data, reservoir potential and extraction methods at the Green Energy
project.
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 pre-date
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. The potential quantity and
grade indicated above is conceptual in nature and has been provided only for
illustration purposes.

About Lithium

Lithium is used for batteries, specialty glass, lubricants, pharmaceuticals
and lithium alloys. Lithium ion (Li-ion) batteries have become the
rechargeable battery of choice in cell phones, computers, hybrid-electric cars
and electric cars. GM, Ford, Toyota, Dodge, Chrysler, Mitsubishi, Nissan,
Tesla, Saturn and Mercedes-Benz have all announced plans to build Li-ion
battery-powered cars. Demand for lithium-powered vehicles is expected to
increase fivefold by 2012. The domestic automotive industry must secure a
lithium source to supply the next generation of hybrid-electric and electric
vehicles. Over 60% of cell phones and 90% of laptops use lithium batteries.
The worldwide market for lithium batteries is estimated at over $4 billion per
year.
