Pancontinental says new 3D seismic over Kenya L8's Mbawa prospect (Origin 75% operator) shows a large structure with possible flat spots. Mapping takes two to three months, a licence-year extension of three months was granted, farm-in talks are under way and drilling is planned for 2011. This is Pancontinental's interpretation, not a result.
