Ecuador-Colombia Interconnector Update

Amerisur Resources Plc ("Amerisur" or the "Company"), the oil and gas producer and explorer focused on South America, is pleased to provide an update on the project to connect the Platanillo field in Colombia with the oil pipeline system in Ecuador, named Oleoducto Binacional Amerisur (OBA).

The civil works at the OBA reception station within the Victor Hugo Ruales (VHR) facilities are 96.6% completed and the 5,000 bbl reception tank and other piping and instrumentation is 78% completed.

The Company has also begun pipe laying operations of the 10" (nominal) line in the VHR field Ecuador.

The line is currently being laid using three work fronts from the VHR OBA Facilities to the northernmost pad in the VHR field, known as VHR 20, a total length of approximately 14 km, and this part of the line is expected to be fully welded and trenched within 4 weeks.

The Company is awaiting the approval of the final environmental license by the Ecuadorian Environmental Ministry. This permit is expected imminently. The permit will allow the drilling of the under river crossing from Pad 9S in Colombia to the Ecuadorian river bank, and the construction of the 10" line from that landfall to the VHR 20 pipeline head. The under river crossing has a design length of 1,410 m, followed by a run length of 3,800 m from Ecuadorian landfall to connection with VHR 20.

The equipment and consumables required to drill the under river crossing are now being mobilised to the Pad 9S location, where site civil works are complete.

The Company expects to perform operational testing and commissioning of the pipeline, measurement and export pumping systems around the turn of the year, followed thereafter by first transport.

An updated presentation on the OBA operations will shortly be available on the Company's website, www.amerisurresources.com.

John Wardle, CEO of Amerisur commented:

"I am very pleased with the advances we have made and look forward to updating shareholders as the project progresses further."
