Africa Oil Corp. (TSX VENTURE:AOI)(OMX:AOI) ("Africa Oil" or the "Company") is pleased to provide an update on the drilling program in Puntland, Somalia.

The Shabeel well has reached a total depth of 3,470 meters and has encountered metamorphic basement at a depth of 3,430 meters and is currently being suspended for future testing. In addition to the previously announced 12 to 20 meter zone of significant hydrocarbon pay in the Upper Cretaceous Jesomma Formation, the well has encountered additional potential net pay sands in the Jurassic Adigrat Formation at a depth of 3,246 to 3,430 meters, several of which exhibited oil and gas shows. Petrophysical analysis of the well log data indicates up to 3 meters of potential hydrocarbon pay in several thin sand units. They are not considered to warrant testing at this time, but do further confirm the existence of a working petroleum system.
