VANCOUVER, British Columbia, May 17, 2005 (PRIMEZONE) -- Montana Oil and Gas Corp. (Other OTC:MOGI.PK - News): Ensign Drilling has resumed drilling at the 6-3-38-3 W5M well, located on the Sylvan Lake Prospect as of Monday, May 16. The county of Red Deer, Alberta has removed a restriction on heavy equipment and trucks on its county roads. As previously reported, the Sylvan Lake Prospect is a well-defined 3-D seismic structural high within a preserved Pekisko remnant ``island'' that may have virgin reservoirs with similar production potential as the adjacent N Pool where six wells have produced 680,000 barrels oil since 1997. In the overall, the Sylvan Field has produced 40 million barrels oil from the Pekisko formation and 50 billion cubic feet gas from the Shunda formation.

The hole is planned to reach a total depth of 7,470 feet. A total of 30 feet in the Shunda gas formations at 7,155 feet and 30 feet of Pekisko oil formation at 7,320 feet may then be tested. The drilling and testing is expected to take approximately 10 days.

Montana Oil and Gas has a 20% working interest in the Sylvan Lake project that has the potential for four oil wells and one gas well. Each well has the potential to produce approximately 150 barrels oil per day from the Pekisko formation with potential reserves of 250,000 barrels oil. In addition, the Shunda gas formation, which is a secondary target, has the potential for approximately 1,000,000 cubic feet gas per day with potential reserves of three billion cubic feet gas.
