InfraStrata plc

("InfraStrata" or the "Company")

Farm-in by Corfe Energy Limited

InfraStrata plc (AIM:INFA), the independent gas storage and petroleum exploration company, is pleased to announce that it has been informed by Corfe Energy Limited ("Corfe"), 50% owned by the Company, that Corfe is to acquire a 12.5% interest in Petroleum Exploration and Production Licence 201 ("PEDL201") located in Nottinghamshire and Leicestershire.

Under the terms of the agreement, Corfe will pay for 25% of the cost of the planned Burton on the Wolds-1 exploration well to earn a 12.5% interest.  This farm-in interest will be acquired jointly from Celtique Energie Petroleum Ltd and Egdon Resources U.K. Limited.

On completion the licence interests in PEDL201 will be as follows:

Egdon Resources U.K. Limited                      37.50% (operator)

Celtique Energie Petroleum Limited               37.50%

Corfe Energy Limited                                      12.50%

Terrain Energy Limited                                   12.50%

The transfer of interests is subject to the approval by the Department of Energy and Climate Change.

PEDL201 is located on the southern margin of the Widmerpool Gulf geological basin. The Burton on the Wolds Prospect has been mapped on proprietary 2D seismic data which was acquired in May 2011. The operator has reported that the prospect has Best Estimate Prospective Resources of 3.57 million barrels of oil ("mmbo") in two reservoir objectives. The shallower target, the Rempstone Sandstone, is productive at the nearby Rempstone oil field and is mapped as having gross Best Estimate Prospective Resources of 1.4 mmbo. A seismic anomaly, possibly indicative of a carbonate reef, underlies the Rempstone Sandstone and has estimated gross Best Estimate Prospective Resources of 2.17 mmbo.

The operator has reported that a potential site has been identified and lease negotiations are progressing along with development of a planning application.  Subject to planning it is intended that the Burton on the Wolds-1 well will be drilled during 2012.

Commenting on the farm-in by Corfe, Andrew Hindle, CEO of InfraStrata plc said:

"The Corfe project represents an exposure to a well in 2012 with Prospective Resources net to InfraStrata shareholders of 0.22 mmbo with no direct funding requirement. We look forward to further updates on the project from the Corfe management."
