Notes to Editors:

Rockhopper was established in February 2004 with a strategy to invest in and carry out offshore oil exploration to the north of the Falkland Islands. The Company floated on AIM in August 2005. 

An extensive work programme was carried out over a number of years on the licences operated by Rockhopper. This has included 2D and 3D seismic and controlled source electromagnetic mapping. In February 2010, the Ocean Guardian drilling rig arrived in Falkland waters to carry out a multi-well drilling campaign. Rockhopper drilled an exploration well on Sea Lion during April and May 2010, the result of which was the first oil discovery and Contingent Resource in the North Falkland Basin. The Sea Lion discovery was successfully tested during September 2010 and June 2011 and was the first oil to flow to surface in Falkland Islands waters. Rockhopper's drilling campaign lasted from 16 April 2010 to 8 January 2012 and resulted in seven successful wells of the ten drilled, with three oil discoveries, three gas discoveries, multiple successful Sea Lion appraisal wells and a successful appraisal well on Casper.

In October 2012 Rockhopper completed a farm-out agreement with Premier Oil plc, whereby Premier Oil acquired 60% of Rockhopper's interests in its North Falkland Basin licences.

In October 2013 Rockhopper agreed with Falkland Oil and Gas to farm-in to licences PL004a and PL004c increasing the Company's interest in those licences to 24%.

Rockhopper currently has a 40% interest in licences PL032 and PL033 operated by Premier Oil plc, and a 24% interest in licences PL004a, PL004b and PL004c, which are operated by Falkland Oil & Gas Limited. PL004b contains the extension to the Sea Lion Field as well as the Beverley, Casper and Casper South discoveries. Rockhopper also has a 3% interest in PL003, operated by Premier Oil plc.
