    Phase 2 shallow drilling programme delayed temporarily by unseasonal rains
    --------------------------------------------------------------------------

AIM quoted Empyrean Energy PLC today announces the following update regarding
phase 2 of the shallow drilling programme at Margarita:

The drilling programme, which was expected to have commenced on 20 May on the
Agavero Prospect, has been delayed by record unseasonal rains and associated
flooding which isolated the drilling rig on a nearby location. The rig has now
been able to move to the Donna Carlota Prospect location to commence operations,
rather than the Agavero Prospect, because floods have now made the Agavero
location temporarily inaccessible.

The Donna Carlota Prospect is one of the three prospects that are analogues of
historic prolific Frio and Vicksburg sands production in the project area at 
less than 2,000 meters depth. The prospects with mean potential target outcomes 
and final well depths are summarised below. As with the successful initial three 
wells program, any commercial discovery made on the prospects will be rapid as 
the project area is crossed by a number of gas pipelines with access rights and
available capacity to tie into.

Prospect          Potential Mean Reserves              Total Well Depth
Agavero           0.7 BCF                              1,341 metres
Dona Carlota      0.8 BCF                              1,524 metres
Climaco           1.6 BCF                              1,981 metres
