PRESS RELEASE

For immediate release: 3 April 2006

EnCore Oil plc

                        Operations Update: Westerdale -1

EnCore Oil plc ("EnCore") is pleased to announce that testing operations on the
Westerdale-1 well have confirmed the presence of gas.

Potential gas pay has been interpreted within two intervals; the Permian age
Brotherton carbonate at a depth of 905 metres, and the Carboniferous sandstones
at a depth of 1,188 metres.

In the initial, unstimulated tests, gas flowed at up to 130,000 cubic feet per
day from the Brotherton interval. This result should be considered inconclusive
as the normal practice when testing a gas discovery of this type is to use acid
stimulation in the test. Due to the planning consent time constraints, this was
not possible at this time and a further test using acidising equipment will be
undertaken in October 2006. A short test of the Carboniferous confirmed the
presence of gas, but only sub-commercial flow rates were achieved.

Commenting on the discovery, EnCore Chief Executive, Alan Booth said: "Following
on from our announcement of the Kirkleatham gas discovery two weeks ago, we are
encouraged that Westerdale has been confirmed as a gas discovery and look
forward to a more conclusive test result in October."

Graham Dore M.Sc. B.Sc, EnCore's Exploration Director, has reviewed and approved
the contents of this announcement

Notes to Editors:

EnCore Oil plc was admitted to AIM on 3 March 2006, following the reverse
takeover of Oil Quest Resources plc by the EnCore group of companies. EnCore
trades under the ticker symbol 'EO.'

The Westerdale-1 well is located in the UK onshore licence PEDL068 situated
within the Cleveland Basin, in which EnCore hold a 20 per cent. interest.

Acid stimulation involves hydrochloric or other acid being injected into the
formation under pressure. The acid erodes the rock, enlarging the pore spaces
and passages through which the reservoir fluids flow. The acid is held under
pressure for a period of time after which the well is cleaned out and the
testing procedure continued.
