Paraguay - Coronillo, Las Palmas (blocks granted) Espartillar (approval in process)

Giles Clarke, Chairman said:

"2011 was a year in which we made strong progress in a difficult environment and the momentum has continued to date in 2012.

"Our ongoing programme is demanding, however very exciting and we remain on track to deliver our 5,000 BOPD year end target. We have an exceptional acreage position, a high reputation as a responsible and able operator and see there being exciting growth opportunities in our core areas in both Colombia and Paraguay."
