The board of Sterling Energy plc would like to bring to shareholders' attention 
the following announcement posted this morning by Fusion Oil & Gas plc:

"Operational Update


The following statement relates to operational developments.

Woodside Mauritania Pty Ltd, Operator of the Mauritania Area B Joint Venture,
reported earlier today that 'a preliminary evaluation of wireline logs and
pressure data acquired from the Chinguetti-4-7 (Tiof West) step-out exploration
well indicates a gas column of approximately 4 metres overlying a gross oil
column of approximately 122 metres.  Water bearing sands have been confirmed
below the hydrocarbon bearing interval.

The top of the hydrocarbon bearing interval was intersected down-dip from the
top of the hydrocarbon bearing interval in the Chinguetti-4-6 (Tiof) discovery
well.  Preliminary analysis of the pressure data indicates that the oil column
is likely to be in direct pressure communication with the oil column intersected
in the Chinguetti-4-6 (Tiof) well.

Further appraisal drilling will be required to assess the significance of the
two wells and to establish connectivity and the net to gross of the reservoir
section.

Since reporting on the well on 9 December 2003, the 36 inch conductor was jetted
to 1,423 metres, 18 inch hole was drilled to 2,127 metres, 13 3/8 inch casing
was run and cemented and 12 1/4 inch hole was drilled to the final total depth
of 2,991 metres.

The well will now be plugged and abandoned, as planned.'
