Ameriwest has reached an agreement with Tyler Rockies Exploration, Ltd. (TREX) whereby Ameriwest can earn a 50% ownership of the approximately 2,800 gross acres within the Area of Mutual Interest (AMI) identified as the Geary Prospect lands located in Natrona and Converse Counties, Wyoming. Ameriwest will operate and receive a 75% Net Revenue Interest ("NRI") until payout which is based on a 3 well program. After payout, and on a well by well basis, TREX reserves an option to "back in" at a 25% working interest.

Ameriwest believes a full field program based on 40 acre spacing could consist of 18 wells at an average depth of approximately 7000 feet. Initial estimates indicate possible reserves of up to 3.15 MMBO at an averaged 175,000 gross barrels per well.

The Geary Prospect is located in the southwestern portion of the Powder River Basin. The main objective is the Cretaceous Dakota sandstone with the possibility of production from other Cretaceous sands; Upper and Lower Muddy, and Wall Creek (Frontier) sands. The prospect is structurally well documented and on trend with existing production which indicates structural/stratigraphic traps with up to 15 feet of net pay shown.

The Geary Prospect is 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, Deer Creek, Midway, North Geary and Geary Dome.
