("Andes" or "the Company" or "the Group")

Acquisition of Interest in Interoil

The Board of Andes (AIM: AEN; BCBA: AEN) is pleased to announce that at the Interoil Exploration and Production ASA ("IOX") Extraordinary General Meeting, which took place today in Oslo, Norway, the shareholders of IOX approved the issue of 330,000,000 shares in IOX to Andes representing 51% of the enlarged share capital of IOX.

As a result of this transaction, the IOX board will be expanded to seven members of which four will be nominated by Andes, including the position of Chairman. The CEO, CFO and General Manager will be appointed by the new Board of IOX.

Andes is also pleased to announce that the Bondholders of IOX have accepted the proposed restructuring of IOX's NOK 310 million (US$42.2 million) corporate bond (the "Bond") and the US$6.2 million debt due to Proseis AG, and replaced it with a new US$32 million bond of IOX (the "New Bond"), denominated in US$ with a coupon of 6% per annum maturing in 2020 with the option to satisfy coupon payments in the first 2 years by issuing additional New Bonds to the equivalent value.

Acquisition highlights

· Provides substantial increase in group cash flow and 2P reserves

· Significant enhancement of Andes's operating capabilities in Colombia

· Diversifies Group's production base to 9 producing fields in two countries

· Addition of robust cash flow generation capable of funding capital expenditure to target additional upside (including all commitments), even at conservative price assumptions, as well as servicing the new debt

· Potential for material synergies across the portfolio given proximity of IOX's operating licences to Andes's current assets in Colombia

· Management believes there is significant resource upside

· Initial controlling 51% stake acquired with funding in place for potential full acquisition via mandatory offer

Background on IOX

IOX operates production and exploration oil and gas licences in Colombia and has 9 years of operating experience in the country. Previously IOX operated in Peru also but these operations were discontinued in November 2014. The Colombian licences currently produce 1,571 boe/d (1,040 bbl/day oil and 531 boe/day gas), and have approximately 5.7 MM boe of net 2P reserves* (3.5 MM bbls of oil and 11.8 BCF of gas).

The acquisition of AEN's interest in IOX would take Andes's net production to approximately 2,500 boepd and 2P reserves to 23 MM boe.

The mandatory offer is exclusively a cash offer and must be outstanding for four weeks according to Norwegian law.

Alejandro Jotayan, CEO of the Company, commented:

"We are pleased to become the majority shareholder of IOX, which will allow Andes to increase and diversify its production and reserve base. Our management and technical capabilities established in the region, combined with IOX's existing operational base and personnel will contribute to accelerating the development of both company's acreage in Colombia. We are acquiring current production, which provides robust cash flow and additional self-funded exploration and development potential."
