             Lidsey Oilfield Update - Work-over and Recompletion

Doriemus Plc (AIM: DOR) is pleased to announce that, as set out in the farm-in
announcement on 18 October 2013, the operators of the Lidsey Oilfield
("Lidsey") in West Sussex have confirmed that they plan to conduct a work-over
and, more significantly, a recompletion on the producing Lidsey-1 Well over the
next few weeks. The Lidsey-1 Well is currently producing 25 bopd of 38 API oil.

As previously announced, Doriemus has agreed with Angus Energy Weald Basin No.
3 Limited ("Angus Energy"), a UK based oil production company, to farm-in to a
participating 10 per cent. interest in Lidsey. Doriemus has a 60 day first
right of refusal period to negotiate increasing its participating interest to
25 per cent.

A contract work-over rig has now been secured to conduct a full well cleanout
and scraper run to the total depth of the well and to perforate a new 10 foot
section of the Great Oolite Reservoir above the existing 2 feet of perforations
responsible for the current 25 bopd oil production. It is expected to arrive in
the next few weeks.

Donald Strang, the Company's Chairman, commented:

"The Company believes that there is potential for oil production at Lidsey to
increase significantly from the current 25 bopd after the planned well
intervention work is complete, particularly after the new perforations in the
Greater Oolite formation."

The Lidsey Oilfield

Lidsey is held under granted United Kingdom Production Licence PL241. Carless
Exploration discovered oil on Lidsey in 1987 when an exploration well
successfully flowed oil. Lidsey has one vertical producing well in the
Jurassic, Great Oolite reservoir. The Lidsey surface facilities are fully
permitted and operational with onsite oil storage of 2,000 barrels.

In 2002, an independent Schlumberger report on Lidsey concluded the most like
1P reserves of the field are 230 mstb or 5.75 per cent. of the STOIIP and with
an additional well the 2P reserve would be 600 mstb or 6.5 per cent. of the
STOIIP.
