Mainland Captures Full Core From Haynesville Well

Mainland Resources has captured a 21-foot full core of the Haynesville Shale from the 60-foot cored interval at its Burkley-Phillips #1 well on the Buena Vista prospect located in Jefferson County, Mississippi.

The well is currently at a depth of 20,471 ft and Mainland will promptly resume drilling. The core will be transported to the Houston, Texas facilities of Core Lab Petroleum Services to initiate a comprehensive core analysis. Specifically, information related to volumes of gas in place within the matrix, porosity, permeability, gas quality, mineralogy and total organic content will be directly analyzed from the full core utilizing industry leading technology.

Mainland is currently drilling ahead of schedule and anticipates it will reach the programmed depth of 22,000 feet in early January, 2011.

Nick Atencio, CEO, states, "This is a great milestone for Mainland. This may be one of the very few cores taken from the Haynesville in Mississippi at this depth and pressure and we are pleased with the amount of core recovered. The data extracted from this core can have material implications with respect to prospectivity within our acreage and can possibly shape the industry's perspective of the Haynesville Shale in Mississippi."

The Company will provide continuous information and updates on the Haynesville Shale formation as it becomes available from our ongoing drilling and analyses.
