Australia-listed junior Invictus Energy has received a farm-in offer for its Cabora Bassa basin acreage in Zimbabwe where it plans to shoot seismic this year as it eyes up potentially huge gas resources.

The news is a further signal of the increased interest in sub-Saharan Africa’s untouched onshore basins in countries such as Namibia, Botswana and Angola.

The Cabora Bassa asset in northern Zimbabwe encompasses the Mzarabani prospect that Invictus estimates could house trillions of cubic feet of liquids-rich gas and is “potentially the largest, undrilled, seismically defined structure onshore Africa".
