Rockhopper Receives Final Processed 3D Data on Falklands License

Rockhopper Exploration has received the final processed volume of 3D data collected by CGG between November 2006 and January 2007. The survey covered an area of over 850 km2 and the additional time taken to process this data was used to further improve the quality of the data.

Interpretation of this data will now commence and is likely to be completed within three months.

The data was collected over licenses PL032 and PL033 where Rockhopper holds a 100% interest in both licenses. Two wells were drilled by Shell on this acreage during 1998. Live oil was recovered from one, while oil and gas shows were found in the other.

NB: This statement has been approved by the Company's geological staff who include David Bodecott (Exploration Director), who is a Member of Petroleum Exploration Society of Great Britain (PESGB) and the American Association of Petroleum Geologists (AAPG) with over 30 years of experience in petroleum exploration and management, for the purpose of the Guidance Note for Mining, Oil and Gas Companies issued by the London Stock Exchange in respect of AIM companies, which outline standards of disclosure for mineral projects.
