Half-Yearly Report Announcement 2015

18 August, 2015

Simon Thomson, Chief Executive, Cairn Energy PLC said:

"We are delighted to have agreement from the Government of Senegal for our extensive evaluation plan which commences shortly with a 3D seismic survey and continues later this year with a multi-well exploration and appraisal programme.

Cairn estimates that the two discoveries made in Q4 2014 and the currently identified prospects and leads have a gross mean risked resource base of more than one billion barrels.

Our aim is to maximise the value of our Senegal asset within a balanced, well-funded company. Cairn is well placed to take advantage of this exciting opportunity as we build on the success of last year's discoveries."
