GREAT WESTERN MINERALS GROUP AND TOYOTA TSUSHO CORPORATION SIGN LETTER OF
INTENT TO COOPERATE ON EXPLORATION PROJECTS

July 21, 2009 - Saskatoon Saskatchewan and Nagoya Japan - Great Western
Minerals Group Ltd. (TSX:V - "GWG") and Toyota Tsusho Corporation (Tokyo
Stock Exchange - "8015T"; Nagoya Stock Exchange - "8015NG") are pleased to
announce that both Companies have signed a non-binding letter of intent (the
"Letter of Intent) to examine the merits of jointly conducting exploration
and development activities on certain of Great Western Minerals' existing
projects (the "Proposed Transactions").

Under the terms of the Letter of Intent, Toyota Tsusho Corporation ("TTC")
and Great Western Minerals Group ("GWMG") will discuss possibilities for the
Douglas River and Benjamin River exploration projects. TTC will have an
exclusivity provision in these discussions for a six month period.

These two projects are of particular interest to TTC since the
mineralization of these two properties appears to be significantly enriched
in the "heavy" rare earth elements ("HREE"). The HREE are high value
products that are critical to the manufacture of high-temperature magnets
used in electric motors for a wide range of applications including hybrid
vehicles and for phosphors used in LCD and plasma flat panel displays.

As reported in the GWMG's news release dated January 7, 2009, assays from
previous sampling of the vein material on the Benjamin River property varied
from 0.6% total rare earth oxide ("TREO") to 1.0 % TREO with over 30% HREE
by proportion, including yttrium. Historic trench sampling of the Douglas
River property in northern Saskatchewan yielded REE grades of up to 10%
yttrium with accompanying high grades of HREE including dysprosium with
grades up to 0.89% representing over 99% HREE and yttrium by proportion.

Toyota Tsusho Corporation, headquartered in Nagoya, Japan, is the sole
trading company of the Toyota Group. The company's business includes
domestic wholesale, exports, imports, overseas trading, contract
construction, and insurance agency businesses. Worldwide, the Toyota Tsusho
Group employs approximately 28,000 people. Consolidated global sales for the
fiscal year ended March 31, 2009 totaled US$64 billion.

Great Western Minerals Group Ltd. is a Canadian-based company exploring for,
and developing, strategic metal resources in North America and South Africa.
Pursuing a vertically-integrated business model, the Company's wholly-owned
subsidiaries of Less Common Metals Limited located in Birkenhead UK, and
Great Western Technologies Inc., located in Troy, Michigan, produce a
variety of specialty alloys for use in the battery, magnet and aerospace
industries. These "designer" alloys include those containing copper, nickel,
cobalt and the rare earth elements.

Jim Engdahl, President and CEO of Great Western Minerals Group said, "We
believe that the joint participation by both Companies in this exploration
and development initiative offers significant potential value for both
Parties. We believe that Great Western Minerals Group has a lot to offer a
partner such as Toyota Tsusho, not only from the potential of our
exploration projects, but from our value added production facilities as
well."

The completion of any Proposed Transaction is subject to several conditions,
including the completion of all necessary legal, financial and technical due
diligence reviews and receipt of all necessary consents and approvals,
including board and regulatory approvals. There is no assurance that a
Proposed Transaction will be completed as proposed, or at all.

John Pearson, MSc., P.Geo., Vice-President Exploration for GWMG, is the
qualified person responsible for reviewing the contents of this news
release.

The TSX Venture Exchange has in no way passed upon the merits of the
Proposed Transactions and has neither approved nor disapproved the contents
of this press release.
