Acquisition of Further Interest in Horse Hill-1 Oil Discovery and Licences, Weald Basin, UK

UK Oil & Gas Investments PLC (London AIM and ISDX: UKOG) announces that it has acquired the entire 3.9% interest of Flowermay Limited ("Flowermay") in onshore Weald Basin licences PEDL137 and PEDL246 ("the Licences"). The Company now holds a 31.2% total interest in the Licences.

The Licences, covering an area of 55 square miles north of Gatwick Airport, contain the Horse Hill-1 ("HH-1") Portland and Kimmeridge Limestone oil discoveries. As previously reported on 21 March, HH-1 flow tested at a significant "North Sea-like" commercial aggregate stable dry oil rate of 1,688 barrels of oil per day. Regulatory permissions are being sought for a significant long-term production testing and appraisal programme of the productive Kimmeridge Limestones and Portland oil-bearing reservoirs.

Transaction Summary

For a total consideration of £1 million, the Company will receive a 3.9% beneficial interest in the Licences via the purchase of Flowermay's remaining 6% shareholding in Horse Hill Developments Ltd ("HHDL"). The total Consideration, with an effective date of 21 July 2016, is comprised of £150,000 payable in cash and £850,000 in the form of the issue of new ordinary shares in UKOG ("Consideration Shares"). The Consideration Shares will be calculated on the 10-day volume weighted average price prior to the completion of the transaction. Completion of the acquisition is conditional on the consent of HHDL. A further announcement will be made on completion.

HHDL and the Company's Interest in the Licences

HHDL is a special purpose vehicle, which owns a 65% working interest and operatorship of the Licences. UKOG now owns a 48% beneficial shareholding in HHDL, which equates to a 31.2% net working interest in the Licences. The remaining 35% interest in the Licences is held by Magellan Petroleum (UK) Limited.

Stephen Sanderson, UKOG's Executive Chairman, commented:

"This acquisition brings our overall interest in the Horse Hill project to 31.2%, a very material interest in a project with multiple oil bearing reservoirs that have been proven to flow at high initial commercial rates. The acquisition is a logical fit within our ongoing strategy to consolidate and expand our licence position in the new and potentially significant Kimmeridge Limestone oil province. We now look forward to the conclusion of the regulatory permit application cycle at Horse Hill and to resuming extended well testing and appraisal drilling at the site."
