                 Drilling Update, Horse Hill-1, Weald Basin UK 
 
Doriemus Plc (AIM: DOR) is pleased to announce that drilling operations on the 
Horse Hill-1 well are continuing successfully and the Marriott 50 rig is now 
drilling ahead at a depth of 116 feet measured depth ("MD") today at 12:00 
hours. Current rate of drill penetration is about 30 feet an hour. 
 
The Horse Hill-1 well is located on the northern side of UK Weald Basin near 
Gatwick Airport and is planned to drill to a Total Depth ("TD") of 8,680 feet 
MD to test a number of conventional oil and gas targets. 
 
The surface casing has been cemented at a depth of 84 feet below ground level 
and the well is now being drilled in 17 1/2 -inch hole to the next casing point 
at about 1,865 feet MD, where a 13 3/8-inch casing will be installed and 
cemented before drilling on. 
 
The primary oil reservoir targets in this well lie in the Jurassic Portland 
Sandstone and the Corallian Sandstone. There are also a number of secondary oil 
targets in the Jurassic aged formations, including the Great Oolite Limestone. 
After penetrating the Jurassic, the well will be drilled to 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 Limited 
("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: 
 
"HHDL has successfully installed the heavy drilling rig and the well is 
proceeding towards the first conventional oil objectives in the Jurassic. As 
the well progresses, we look forward to updating the market with any 
significant news."
