Amerisur Resources Plc provided an update on operations in the Platanillo field, Colombia. The Company has reactivated a limited production volume from Pad 3N in the Platanillo field. This step has been taken due to an improvement in operational netback from this production pad, on the basis of cost reductions achieved through efficiencies and negotiations of tariffs with service providers, the improvement in current sales prices and the availability of additional reception volumes at the Orito station operated by Ecopetrol. Pad 3 is currently producing around 1,300 BOPD, and entire field production is currently approximately 5,030 BOPD. 100% of this volume is being delivered to Orito. At the same time Amerisur has taken the opportunity to re-enter certain wells to perform chemical treatments to improve well production. Operational netback to the Company during early April was U24 per bbl, with an estimated sales price of $51, and the volume contribution from Pad-3N is expected to increase operational netback to $29 per bbl at a sales price of $55. Once the interventions of wells on Pads 9 and 5 are completed, field production in May is expected to be around 5,600 BOPD, with an operational netback of $30 per bbl in May, assuming that this volume can continue to be delivered into the Orito facility.

Capex guidance for the year remains unchanged from the announcement made on 2nd February 2015.
