John Wardle, Chief Executive of Amerisur commented:

"We are very pleased to announce this important addition to our Putumayo portfolio. We have extensive operating experience in this area where our Platanillo field and Put-12 block also lie. In Put-30 we will explore to evaluate the potential of producible heavy oil deposits in the Neme formation. The presence of this heavy oil zone has been demonstrated in many wells within this part of the basin over the years, and we believe the time has now come to add such prospects within our portfolio. The potential resources of the area are of significant size and we look forward to a rapid and efficient exploration and evaluation programme. On success, the mix of Put-30 heavy crude with our light oil from our developments and exploration activities to the south will be a very exciting and strategic combination. Our joint venture partner, Talisman Colombia, is a very successful and experienced operating company which has had great success in remote regions in other countries and we very much look forward to working with them."
