Doriemus disposes of 60% of its Interest in Horse Hill for circa $3.5 million

Doriemus still retains a 4% in Horse Hill Developments Limited

Doriemus Plc (ASX: DOR)("Doriemus"or the"Company"), today announces it has signed a binding Heads of Terms to sell 60% of its 10% interest in Horse Hill Developments Limited ("HHDL") to UK Oil and Gas Plc ("UKOG") for a consideration 129,629,630 new ordinary shares in UKOG to Doriemus, worth approximately $3.5 million at UKOG's closing price in London yesterday at 1.5 pence per share at an exchange rate of GBP:AUD of 1.81.

Doriemus will still retain a 4% interest in HHDL, post completion of the transaction and UKOG will then hold a 77.9% direct interest in HHDL and a majority 50.635% interest in the Horse Hill oil field and licences.

Completion will occur on execution of formal sale and purchase agreements which is expected to occur over the next two to three weeks, at which time Doriemus will provide a further update.

The completion of this transaction will significantly strengthen Doriemus' balance sheet as it continues to evaluate and finalise the potential transactions in Western Australia, as recently announced, while allowing Doriemus to retain a stake in the Horse Hill project. Doriemus also considers that it is important for the long term stability and development of the Horse Hill oil field, that there is a clear majority shareholder controlling and operating the Horse Hill asset.

As mentioned above, this transaction will assist the Company as it looks to shift a lot of its focus towards finalising the recently announced deals in Western Australia, where if completed, Doriemus will not only have a significant stake (50%) but it will also be acting as operator of the assets (as opposed to being a minority passive shareholder of assets). If required, further rationalisation of the Company's existing portfolio may be considered to assist with the Company's focus shifting towards this objective.

David Lenigas, Doriemus Executive Chairman, commented:

"The Horse Hill oil discovery near London's Gatwick International Airport, just south of London, has been an outstanding UK onshore success and we are excited about the prospects of still being a supportive shareholder and participating in to long term oil production during 2019. Doriemus is very proud to have been part of the consortium that has funded this important UK discovery through thick and thin, and we look forward to continue being part of its future development. On closing, Doriemus will be in a much stronger position to a) fund the longer term production plans at Horse Hill, and b) embark on its previously announced oil and gas expansion plans in Western Australia. The sale of 6% of HHDL will result in a profit on this portion of our HHDL investment of about $1.8m whilst still retaining 4% of HHDL going forward to hopefully add even more value for Doriemus shareholders in the future."
