Contango Oil & Gas Company announced today a significant discovery at its Dutch prospect located offshore Gulf of Mexico at Eugene Island block 10. The Dutch #2 well is located approximately 1 mile from the Dutch #1 well and has extended the reservoir found by the Dutch #1 well.

Both wells are operated by Contango Operators, Inc. (“COI”), a wholly-owned subsidiary of the Company. The two Dutch wells will produce from the same reservoir at a depth greater than 15,000 feet.

Contango’s independent third party engineer estimates the two Dutch wells have total proved reserves of 158 billion cubic feet equivalent (“Bcfe”) (45.8 Bcfe net to Contango) with an additional 266 Bcfe of probable reserves (77.1 Bcfe net to Contango) should future field extension/exploration wells prove successful.

Completion and testing operations are expected to take three weeks with production of the Dutch #2 well estimated to commence between July and August 2007. The Company plans to begin drilling Dutch #3, a field extension/exploration well, as soon as completion operations are finished at Dutch #2. The Dutch #3 well is expected to commence drilling in May 2007 and has an 8/8ths cost of approximately $25.0 million ($4.0 million net to COI and $14.1 million net to REX).

The Dutch #3 well is located 2,200 feet southeast of the Dutch #1 well. The Dutch #1 well is currently flowing at 35 million cubic feet equivalent per day.

COI has an approximate 16% working interest and Republic Exploration LLC (“REX”), a subsidiary in which the Company owns a 42.7% interest, has an approximate 56.5% working interest in our Dutch discovery or a combined working interest net to Contango of approximately 40%. The net revenue interests to COI and REX are approximately 12% and 42%, respectively, or a combined net revenue interest net to Contango of approximately 29%.

Kenneth R. Peak, Contango’s Chairman and Chief Executive Officer, said, “All three of our natural gas value driven strategies are progressing well. Our Dutch discovery is a tremendous achievement for the Company and our Gulf of Mexico exploration team, though much work remains to be done including drilling an additional five to seven field extension/exploration wells at an estimated 8/8ths cost of $25.0 million per well. This discovery, while already of major importance to Contango, is very -1- early in its exploitation. We expect to learn a great deal about this reservoir and the ultimate recoverable reserves as we drill, log and hopefully complete and produce each well, including the production testing of the Dutch #2 well which we anticipate will happen later this month. Our Fayetteville Shale exploration program will be spudding the first of five wells in the “sweet spot” of that play, while our investment in Freeport LNG is now only a year away from first revenues. I believe we have significant remaining upside opportunities in each of these investment strategies and that will continue to be our focus.”
