Roc Oil Company Limited05 December 2006 5 December 2006 ROC OIL COMPANY LIMITED ("ROC") STOCK EXCHANGE RELEASE EXPLORATION DRILLING UPDATE OFFSHORE MAURITANIA Further to its Stock Exchange Release on 28 November 2006 regarding theDana-operated Aigrette-1 exploration well in Block 7, ROC advises that the wellwas drilled to a Total Depth of 5,152 metres without encountering furtherhydrocarbons. As previously reported, the preliminary interpretation of the drilling data andthe wireline logging programme indicates that a gross hydrocarbon column ofabout 20 metres has been encountered and confirmed in fluid samples to be oil.The operator will conduct further analysis over the coming months. However, itis ROC's view that whilst this result is technically very encouraging, at thisstage, it is likely to be sub-commercial. As at 0600 hours (local time) on 4 December the current operation was pluggingand abandoning the well. Aigrette-1 is located in a water depth of 1,358 metres approximately 43 kmnorth- northwest of the 2003 Pelican-1 gas discovery and 193 km north-northwestof the Chinguetti Oil Field. Following completion of plug and abandonment operations, the Atwood Hunter rigwill return to drill the Woodside-operated Chinguetti-18 development well.
