14/15-5 Well Spud and Drilling Order Update

Rockhopper Exploration plc (AIM: RKH), the oil and gas exploration and production company with interests in the North Falkland Basin and the Greater Mediterranean region, announces that the 14/15-5 well (the "Well") was spudded, by Premier Oil as operator, on 6 March 2015.

The well is located on licence PL004b in which Rockhopper has a 24% working interest and is an exploration well on the Zebedee prospect. The Zebedee well will test a total of seven stacked fan bodies with varying geological chances of success (GCoS) of 9 - 52%. Net prospective Pmean resources are estimated at 68 million barrels (mmbbls) in a range of 13 - 178 mmbbls.

Drilling, coring and logging operations are expected to take approximately 30 days. A further release will be made when those operations are completed.

Current planned drilling order:

The North Falkland Basin wells are anticipated to cost approximately US$50 million each. As a result of the various carry arrangements, the total net cash exposure to Rockhopper of the four wells is estimated at approximately US$25 million. No drill stem testing is planned during the campaign.

Samuel Moody, CEO, commented:

"We are very pleased to be drilling again in the North Falkland Basin and to be targeting prospects we first mapped in 2012. This exciting exploration campaign exposes shareholders to a range of prospects and risks which in the case of success will add significantly to the value of the already discovered and appraised Sea Lion field."
