               Lidsey Oilfield Update- Increased oil production

Doriemus plc (AIM: DOR) is pleased to announce that, further to the
announcement on 7 November 2013, the well stimulation phase of the Lidsey-1
well work-over on the Lidsey Oilfield ("Lidsey") in West Sussex has been
successfully completed and oil production from this first phase of the planned
three phase programme has resulted in an initial 236% increase in production in
the first 24 hours to 84 bopd net from the previous 25 bopd.

As previously announced, Doriemus owns a 10% participating interest in the
Lidsey oil field and has a first right of refusal to increase its participating
interest to up to 25%.

Donald Strang, Doriemus' Chairman, commented:

"The first phase of a three stage programme has gone better than expected and
we look forward to the results of the next two phases of work being completed
at Lidsey over the coming weeks."

Notes to Editors

The Lidsey Oilfield is owned by Angus Energy Weald Basin No. 3 Limited (90%
interest and Operator) and Doriemus (10% interest), and is held under United
Kingdom Production Licence PL241. Lidsey has one vertical producing well in the
Jurassic, Great Oolite reservoir which has produced an average of 25 bopd of 38
API oil over the past 12 months. The Lidsey surface facilities are fully
permitted and operational with onsite oil storage of 2,000 barrels.

The full work-over programme on Lidsey-1 will comprise a well stimulation, a
full clean-out of the well to total depth and perforation of a potential 30
feet of new oil zones above the existing 2 feet of perforations, followed by
the installation of a new completion assembly. The entire programme is expected
to be completed over the coming weeks.
