Appointment of independent non-executive Director

Amerisur Resources Plc ("Amerisur" or the "Company"), the oil and gas producer and explorer focused on South America, is pleased to announce the appointment of Dana Coffield to the Board as an independent non-executive Director.

Dana Coffield, who will join the Board on 7th April 2017, has over thirty years of international E&P experience encompassing North and South America, North Africa, Middle East and South East Asia. Between 2005 and 2015 Dana was Co-founder and CEO of Gran Tierra Energy Inc. and during his ten years at the helm, the company successfully grew reserves and production year on year and became a leading player in the operationally challenging Putumayo basin in southern Colombia. Dana is well recognised in the oil and gas investment community, with government representatives and with industry peers for his accomplishments in South America and particularly in Colombia.

Dana is currently Co-founder, President and CEO of Corvus Resources Inc. Prior to his role at Gran Tierra Energy, Dana was VP Middle East at Encana Corporation, VP Middle East at Alberta Energy Company Ltd and he held a variety of geologist positions with Atlantic Richfield (ARCO) subsidiaries around the world.

The appointment follows the announcement made on 3rd January 2017 that the Board was seeking to appoint two additional independent non-executive Directors: one with significant City experience; and one with considerable oil industry experience. The process, which is nearing completion, is objective, thorough and rigorous and is being overseen by Chris Jenkins, independent non-executive Director and member of the Nomination Committee. In line with corporate governance best practice, Preng & Associates, a leading executive search firm dedicated to the energy industry, has been managing the search process. It is expected that a further independent non-executive Director appointment with considerable City experience will be made in the near future.

The Company also announces the retirement of Nigel Luson from the Board effective today. Following the above appointment of Dana Coffield taking effect, the Board of Amerisur will comprise two executive Directors, a Chairman and four independent non-executive Directors, exceeding the expected level of independent director representation for an AIM listed company.

It is intended that Dana Coffield will join the Remuneration Committee.

Chris Jenkins, independent non-executive Director and member of the Nomination Committee, who is overseeing the search process, said:

"With the support of Preng we are running an objective, thorough and rigorous process in line with best practice corporate governance and recruitment procedures and I am confident that in Dana Coffield we have appointed an outstandingly qualified oil industry candidate."

Giles Clarke, Chairman of Amerisur, commented:

"I take pleasure in welcoming Dana Coffield to the Board of Amerisur as an independent non-executive Director. His independence, wide range of experience in the oil industry, and in Colombia will provide balance, challenge and a sounding board to the executive and add considerable value to your Board. I would like to thank shareholders for their continued engagement on this process.

"I would also like to thank Nigel Luson for his four years of service on the Board and I speak for the entire Amerisur team in wishing him best wishes for the future."
