kurnia update

Further to release COE061207a (Kurnia-1 Update), Cooper Energy provides the following update for
Shareholders:

• Initial wireline log data has been obtained over the formation section from 3,004 to 3,036
metres.

• The logs obtained to date have captured data that is then interpreted to provide an indication of
the fluid type in the formation (gas or liquid) and the quality of the formation. The potential
productivity of the interval is yet to be determined.

• A preliminary interpretation of the data from the logs obtained to date demonstrates that the
formation appears to be a poor quality inter-bedded carbonate and shale. There is
approximately 30 metres of formation with approximately 10 metres of clean carbonates that
appear to be gas bearing.

• The section that has been logged is an inter-bedded carbonate and shale formation. Correlation
with nearby wells indicates that this section may lie above the main Kujung II carbonate, which
is typically a massive and clean limestone. The interpretation will become clearer as we drill
ahead.
