                   Update on investment in Lidsey Oil Field

Doriemus Plc (AIM: DOR) is pleased to announce that work has started on the
second stage well intervention on the producing Lidsey-1 well in the UK Weald
Basin. This second stage production enhancement programme is expected to take
approximately one week to complete.

Donald Strang, the Company Chairman commented:

"The production improvement programme on the Lidsey Oil Field is designed to
open up the existing un-tapped sections of the Lidsey-1 well. Results of this
programme will be announced when completed."

Lidsey Oil Field (20% owned by DOR and operated by Angus Energy):

The Lidsey Oil Field ("Lidsey"), in the Weald Basin, is held under United
Kingdom Production Licence PL 241. Oil production was 25 bopd, prior to a
re-completion programme completed in November and December 2013, which resulted
in a temporary boost in oil production. Production has steadily declined to 36
bopd and Angus Energy has now formally advised the partners in Lidsey that a
new re-completion is being planned in order to again increase production.

Lidsey has a fully permitted and operational 2,000-barrel storage facility and
its 38 API oil is regularly trucked and sold to the Perenco Oil Refinery.

In March 2014, DOR announced that RPS had independently assessed that, as at 31
December 2013, the Lidsey Field contained 9.52 million barrels (gross) of P50
best case Oil In-Place.

The drilling of the new Lidsey-2 well has now been postponed until after the
Lidsey-1 well re-completion has been completed.
