ASX RELEASE
DRILLING ACTIVITY UPDATE
Castanha-4 Appraisal Well, Onshore Angola
Lacula Oil Company Limited, a wholly owned subsidiary of ROC, advises that the Castanha-4 appraisal well
has been drilled to a total measured depth of 2,343 metres and has been suspended following a preliminary drill stem test. Initial evaluation has indicated that the well encountered a gross hydrocarbon column of approximately 15 metres in the Chela Formation.
Production testing of the Castanha-2, Castanha-3 and Castanha-4 appraisal wells is planned to commence
over the coming weeks.
Following the completion of production testing operations, the Joint Venture will then decide on whether to
declare Castanha as a Commercial Discovery. This decision is anticipated during 1H 2011.
