Colombia Asset Acquisition

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 corporate activities in Colombia.

Put 30 and Put 9 Acquisition

The Company is pleased to announce the closing of a transaction with Talisman Colombia Oil & Gas Ltd to acquire, subject to approval from the Agencia Nacional de Hidrocarburos ("ANH"), the remaining 50% working interest in the Put 30 contract area and a new 40% working interest in the Put 9 Contract. The application for approval to ANH includes the appointment of Amerisur as operator of Put 30. Put 9 is located immediately to the north of Put 12 and to the east of Platanillo and is operated by Meta Petroleum Corp. with a working interest of 60%.

John Wardle, CEO commented:

"Our already very strong acreage position has been further strengthened with the acquisition, subject to ANH approval, of these Talisman assets. The acquisition cost to the Company was non-material. Put 9 is a key block which is located within the OBA cluster, adjoining Platanillo and Put 12 and is very prospective in our view. On the basis of existing seismic data there are several interesting structures which are shared between Put 12 and Put 9. Also, there are independent structures which lie within Put 9. We are currently performing detailed work to link the geological models of Put 12 and Put 9, after which an independent resources report will be commissioned covering both assets. Put 30, a heavy oil play, will be, upon approval, 100% owned by Amerisur and, coupled with its adjoining block Andaquies where we also hold 100% working interest, offers a variety of compelling opportunities."
