News Release - Wednesday, August 25, 2010

Mesa Uranium Corp. (TSX-V: MSA) is pleased to announce that it has
signed a letter of intent to acquire the Pine Valley Potash Project
located in southwestern Utah. The project totals 5,227 acres
consisting of State of Utah Leases and Federal Potash Prospecting
Permits.

The deposit has an in-situ mineral inventory (non NI 43-101 compliant)
of 82.7 million tons averaging 35.5% alunite (19.5 million tons
indicated and 63.2 million tons inferred). This resource is historical
in nature and was calculated using US Bureau of Mines protocols which
was the industry standard prior to NI 43-101 standards. Investors are
cautioned not to use this information in making investment decisions.

The commercial products from alunite are potash, as sulfate of
potassium ("SOP"), sulfuric acid and alumina. The resource could
theoretically support an operation producing 104,000 tons of SOP,
200,000 tons of alumina and 184,000 tons of sulfuric acid per year for
more than 25 years. The deposit is shallow and would be mined by
low-cost surface mining methods. The area is accessed by well
maintained gravel roads, supports year round work and is 15 miles from
a main line siding of the Union Pacific Railroad.

Under the letter of intent, Mesa will acquire a 100% interest in the
project by paying the owner $25,000 upon signing a definitive
agreement, $25,000 and 800,000 Mesa shares on January 1, 2011,
thereafter payments of $10,000 annually. The owner will retain a 1%
NSR royalty which Mesa has the option to purchase one-half for US
$500,000. Closing of the transaction is expected on or before October
4, 2010. The transaction is subject to completion of final due
diligence by Mesa, execution of a binding definitive agreement and
regulatory approval.
