Celtic Sea Portfolio Update

26 April 2016

Lansdowne Oil & Gas ("Lansdowne" or "the Company"), the independent oil and gas company focussed on offshore Ireland, provides an update on Lansdowne's licences in the Celtic Sea offshore the south coast of Ireland.

Standard Exploration Licences 5/07 (Rosscarbery) and 5/08 (Amergin)

Due to adverse industry conditions, attempts to farm-out SEL 5/07, containing the Rosscarbery and SE Rosscarbery gas prospects, and SEL 5/08, containing the Amergin prospect, have been unsuccessful. As Lansdowne has not been able to demonstrate that drilling will be achieved in 2016 these licences have lapsed with effect from 31 December 2015.
