Ameriwest Energy Accepts Additional Geary Prospect Land Acquisition Offer

CASPER, WY, Aug 27 (MARKET WIRE) --
Ameriwest Energy Corp. (OTCBB: AWEC) ("Ameriwest" or the "Company")
wishes to announce that it has formally advised Muddy Mineral
Exploration, LLC of Casper, Wyoming of its intent to exercise its right
to purchase certain oil and gas mineral leases adjoining Ameriwest's
recent Geary Prospect acquisition.

Muddy Mineral Exploration, LLC ("Muddy Mineral") has presented the highest
bid in auction to the United States Department of the Interior's Bureau of
Land Management for the purchase of a 10 year Federal mineral lease on
approximately 240 acres of land mainly located within the Area of Mutual
Interest ("AMI") identified as the Geary Prospect lands located in Natrona
and Converse Counties, Wyoming.

Muddy Mineral had extended an offer of first right of refusal to Ameriwest
on an 80% Net Revenue Interest ("NRI") basis subject to the successful
issuance of the Federal lease. This offer has been accepted by Ameriwest
and upon completion will expand its holding in the Geary Prospect to
approximately 3,040 gross acres.

The Geary Prospect is located in the southwestern portion of the Powder
River Basin with the main objective based on an up-dip continuation of one
of the Dakota sand bars that has already produced in excess of 300,000
barrels of oil from 2 wells. In the immediate area of the Geary Prospect,
millions of barrels of Dakota oil have been produced from fields such as;
Big Muddy, Salt Creek, Cole Creek, South Cole Creek, Burke Ranch, Burke
Ranch East, Glenrock Block A, Midway and Geary Dome.

Full details regarding the agreement will be submitted shortly to the
Securities and Exchange Commission ("SEC") as part of the Company's Form
8-K regulatory filing disclosure.
