Amerisur Resources Plc ("Amerisur" or the "Company"), the oil and gas producer and explorer focused on South America (LSE: AMER), provides an update on the certified reserves for its production assets in Colombia.  

Following receipt of an independent reserves report for the Platanillo and Mecaya fields undertaken by Petrotech Engineering Ltd, and the CPO-5 block undertaken by McDaniel and Associates Consultants Ltd as at 31 December 2018, using the standards set by the Oil and Gas Reserves Committee of the Society of Petroleum Engineers, certified 1P (Proven) working interest field reserves were 17.82 million barrels of oil ("MMBO") (2017: 13.94 MMBO) and 2P (Proven and Probable) working interest reserves were 25.59 MMBO (2017: 20.70 MMBO). Total production from the Platanillo field during 2018 was 1.61 MMBO and total production from the CPO-5 block, (Mariposa and Indico fields) at 31 December 2018 was 1.15 MMBO. 

This represents an increase of 27.83% in 1P and 23.62% in 2P reserves over year end 2017, and is due to the drilling success in the CPO-5 block previously reported.
