Acquired a 100% working interest in approximately 1,260 net leasehold acres in western Mississippi.

Mainland Resources Inc., Houston, (OTCBB: MNLU) has acquired a 100% working interest in approximately 1,260 net leasehold acres in western Mississippi, within the same geological region as its Buena Vista project in Jefferson County, Mississippi.

Mainland is currently testing the Buena Vista prospect with the drilling of its Burkley-Phillips No.1 well. The well was spudded on July 21 and has a projected drilling depth of 22,000 feet. The well will test the Haynesville shale and potentially shallower productive formations.

This new acreage is similar to the Buena Vista prospect, originally developed by a major oil company, targeting more than 20,000 feet, in the early 1980s. According to data received by the company, there is a gas zone at approximately 15,000 feet, with good porosity and mud log shows. There are three to four different Tuscaloosa oil zones between 13,000 feet and 14,000 feet, with good mud log shows and porosity. All the zones calculate to be potentially productive.

This interval includes the Tuscaloosa Marine shale, an oil-bearing shale known to cover fourteen parishes and counties in Louisiana and Mississippi.

Mainland president Mike Newport says, "This is another solid prospect for exploration by Mainland that's very similar to the Buena Vista. The 1260 net acres would support two gas wells at the depth of 15,000 feet. In the event the oil zones are productive, they could support as many as 15 to 16 locations on each of the four oil bearing zones."

Mainland Resources has oil and gas assets in the Haynesville shale in northwestern Louisiana.
