                 Drilling Update, Horse Hill-1, Weald Basin UK

Doriemus plc (AIM: DOR) advises that the Horse Hill-1 well has intersected the
Portland Sandstone over the weekend and has encountered oil shows identified by
mud logging from 2,100 feet to 2,140 feet measured depth ("MD"). At 14:00 hours
yesterday, the well was drilling ahead at 3,030 feet MD towards the other
primary and secondary targets.

Sandstone drill cuttings recovered from the well have been analyzed and are
confirmed by the operator to have "a dull yellow fluorescence with a slow
diffuse light blue cut with a trace of residual oil ring". This indicates the
presence of oil within a porous and permeable rock matrix. Gas readings within
the mud over the same interval were also elevated and recorded gases
compositions consistent with the presence of oil.

The Horse Hill-1 well is located on the northern side of UK Weald Basin near
Gatwick Airport and is planned to test a number of conventional oil and gas
targets. The primary oil reservoir targets in this well lie in the Jurassic age
Portland Sandstone and the Corallian Sandstone. There are also a number of
secondary oil targets in the Jurassic formations, including the Great Oolite
Limestone. The well is presently being drilled to the second of the primary
targets in the Corallian Sandstone.

Electric logs will be acquired on reaching the third casing point at
approximately 5,900 feet MD before setting a 9 5/8-inch casing. The well will
then be drilled with an 8 ½-inch hole will be drilled to 8,658 feet total depth
("TD") in order to test for Triassic aged formations which are expected to
contain gas.

Doriemus owns a 10% direct interest in Horse Hill Developments Ltd ("HHDL").

HHDL is a special purpose company that owns a 65% participating interest and
operatorship of onshore licences PEDL137 and the adjacent licence PEDL 246 in
the UK Weald Basin. The participants in the Horse Hill-1 well are HHDL with a
65% working interest and Magellan with a 35% interest.

Donald Strang, the Company's Chairman, commented:

"Progress on this conventional well has so far been encouraging and we are
pleased to report that oil shows have been encountered in the Portland
Sandstones. The well will need to be electronically logged at the next casing
point to understand the significance of these oil shows in the Portland and we
look forward to reporting further drilling updates as the well progresses."

Glossary:

Fluorescence: The natural property of minerals and fluids to emit light,
characteristic in certain situations, of the presence of hydrocarbons.

Drill cuttings: Rock chips from the subsurface formations recovered by
filtering the drilling mud.

MD: measured depth.

(Drilling) Mud: Drilling fluid used to clean and lubricate the drilling process
and recover samples of the subsurface formation to surface.
