Amerisur Resources Plc ("Amerisur" or the "Company"), the oil and gas producer and explorer focused on South America, announces that it is hosting a site visit for sell-side analysts to the Company's operations and offices in Colombia.  Today, a presentation will be made by management, which will be made available on the Company's website www.amerisurresources.com shortly.

The presentation sets out Amerisur's strong financial position, with its solid, low opex production base, its diverse portfolio of near term assets, with detail on its strategic position in the under-explored Putumayo basin.  The presentation describes the progress of the OBA pipeline and the impact this strategic piece of infrastructure will have on the OBA cluster of assets and the Company's wider business.  It also gives details of the fully funded 11 well drilling programme over the next 15 months to convert resources into reserves and increase production, adding new production centres.

Finally, it gives details on the Company's strategy to 2019, the visibility of diversity of production base from one to up to five fields on exploration success, and of the broad portfolio of longer term exploration assets.

Part of the presentation includes capex and production guidance and drilling guidance for 2017.  The Company is expecting a 2016 exit production rate of 7,200 BOPD and to produce between 7,500 and 8,500 BOPD in 2017.  The Company is expected to spend $52m in capex between now and the end of 2017, including drilling 11 wells across the Company's portfolio and conducting seismic operations and a long term test on the Coati field.
