Planning Permission Granted for Further Flow Testing and Drilling

Horse Hill Oil Discovery, Weald Basin, UK

Doriemus plc (Listed in Australia ASX:DOR and listed in London NEX:DOR) (“Doriemus” or the “Company”), is pleased to announce that it has been informed by Horse Hill Developments Ltd ("HHDL"), the operator of Horse Hill licences PEDL137 and PEDL246, containing the Horse Hill-1 ("HH-1") oil discovery, that on 18 October 2017 Surrey County Council's Planning and Regulatory Committee granted planning permission to enable HHDL to carry out extended flow tests at HH-1, plus drill and test both a sidetrack from the existing HH-1 well and new borehole HH-2. The committee voted overwhelmingly in favour of HHDL's planning application.

Along with the Environment Agency's approval of all necessary permits, HHDL can now proceed with its Horse Hill appraisal programme as soon as the similar extended flow testing programme has been completed at our Broadford Bridge well site in West Sussex.

Doriemus owns 10% of HHDL, which owns 65% of the Horse Hill Licences which hosts the HH-1 oil discovery well, or a 6% attributable interest in the licences.

The HH-1 Kimmeridge Limestone and Portland oil discovery well is located within onshore exploration Licence PEDL137, on the northern side of the Weald Basin, 3 km north of Gatwick Airport. As previously reported in February and March 2016, two naturally-fractured limestone members within the Kimmeridge section, known as KL3 and KL4, flowed dry, 40-degree API oil, at an aggregate stabilised natural flow rate of 1,365 barrels per day ("bopd") with no clear indication of depletion.

The overlying Portland flowed dry, 35-degree API gravity oil at a stable pumped rate of 323 bopd. The Portland oil was produced at the rod-pump's maximum achievable rate and thus flow was constrained by the pump's mechanical capacity.

The directors of the Company accept responsibility for the contents of this announcement.
