Drilling begins at Horse Hill

Regency Mines PLC (AIM: RGM) is pleased to announce that drilling operations on the Horse Hill-1 well have now commenced.

The Horse Hill-1 well is planned to be drilled to a Total Depth ("TD") of 2,646 metres (8,680 feet) and is designed to test for a number of conventional stacked oil targets in the Jurassic, as well as a deeper conventional gas target in the Triassic.

The operator, Horse Hill Developments Ltd ("HHDL"), is a special purpose company with a 65% operating interest in the PEDL 137 license in the Weald Basin to the north of Gatwick Airport in Surrey. Regency has binding agreements in place to own a direct 5% interest in HHDL and holds an additional 0.628% interest by virtue of its 12.56% ownership in Alba Mineral Resources PLC ("Alba"). Alba also has binding agreements in place to own a direct 5% of HHDL.

The participants in the Horse Hill Prospect are HHDL (65%) and Magellan Petroleum Corporation (35%).

Andrew Bell, the Company's Chairman, commented:

"After a few weather delays we spud at Horse Hill to test one of the largest onshore targets to be drilled for many years. It has taken fifty years of endeavour and appraisal to follow up the first well drilled on the edge of this target. The risk-reward on the Horse Hill-1 well is great on the oil alone, as we test a number of conventional oil formations, but the well will also test for potential conventional gas in the deeper Triassic formations which, if discovered, might be of still greater significance."

Prospective Resource Prospective resources are estimated volumes associated with undiscovered accumulations. These represent quantities of petroleum which are estimated, as of a given date, to be potentially recoverable from oil and gas deposits identified on the basis of indirect evidence but which have not yet been drilled. This class represents a higher risk than contingent resources since the risk of discovery is also added. For prospective resources to become classified as contingent resources, hydrocarbons must be discovered, the accumulations must be further evaluated and an estimate of quantities that would be recoverable under appropriate development projects prepared.
