Occidental Andina, LLC entered into a conditional agreement to acquire 50% interest in the Put-8 exploration licence in the Putumayo region of Colombia from Amerisur Resources plc (AIM:AMER) for $19.1 million on March 18, 2019. The consideration will be paid in cash and has been pre-paid by Occidental on the basis that it is refundable if the transaction does not complete. Amerisur will retain the operatorship of Put-8 following completion of the transaction. The transaction is conditional upon the approval by the Colombian National Hydrocarbons Agency (the "ANH") of the transfer of a 50% interest from Vetra Exploración y Producción Colombia SAS to Amerisur, pursuant to a right of first refusal and the subsequent application for and approval of the transfer of a 50% interest in Put-8 from Amerisur to Occidental by the ANH. The transaction is expected to be broadly neutral to Amerisur's unrestricted cash position. Callum Stewart, Nicholas Rhodes and Ashton Clanfield of Stifel Nicolaus Europe Limited acted as financial advisor to Amerisur. Occidental Andina, LLC completed the acquisition of 50% interest in the Put-8 exploration licence in the Putumayo region of Colombia from Amerisur Resources plc (AIM:AMER) on April 4, 2019. The transaction between Vetra and Amerisur occurred on April 3, 2019. ANH approval was pending for both the transactions. As set out in the SPA, in the event that the ANH does not approve the PUT-8 disposal, Amerisur will be required to repay the $19.1 million received from Occidental.
