Irwin Energy Participates in 10,000 Acre Oil and Gas Prospect

Initial Well Planned to Test Supai Reservoir for Oil, Natural Gas and Helium

Irwin Energy, Inc. (OTC: IWNN) (the "Company") is pleased to announce that on May 1, 2005, it entered into an agreement with Crossroads Exploration & Production LLC ("CREP") for an undivided 20% working interest in the 10,021.47 acre Concho Dome leasehold, in Apache County, Arizona. Under the terms of the Agreement, the Company paid the gross sum of USD $72,200 for its share of the turnkey drilling expense and estimated completion expense. The Company's working interest is based upon the actual cost of the project.

Under the terms of the Agreement, CREP agreed to commence operations for the drilling of an initial well designed to test the depths of oil, natural gas and helium. Initial plans call for the test well NZOG 17-1 to be drilled to a depth of 2,200 feet or to a depth sufficient to test the Permian Supai foundation for the presence of oil, natural gas and helium.

The Supai foundation (Permian) is the principal drilling objective. The Supai foundation has been responsible for most of the oil and gas shows encountered in wells in Arizona's Holbrook Basin. The Supai foundation typically consists of sandstone, siltstone, shale, limestone, dolomite, anhydrite, and salt, depending on location. Many wells drilled in the Holbrook Basin have encountered oil and gas shows in Supai, including small amounts of free oil in some tests. The presence of these shows would indicate that most of the rocks are thermally mature and in the oil window.
