Kiliwani Operations Update

Aminex is pleased to note that Orca Energy Group Inc. ("Orca") has recently announced that the 3D seismic acquisition programme, covering a total area of 200 km2 to include the adjacent Songo Songo Licence with a ca. 12.5 km2 incursion into the Kiliwani North Development Licence ("KNDL"), has been awarded to African Geophysical Services LLP ("AGS"). Having now received all environmental approvals, Orca is targeting completion of the acquisition programme before year end to align with the optimum weather window and assure highest quality data acquisition. Whist the survey has been designed to better image the structural complexities of Orca's Songo Songo gas-field, the data to be acquired over KNDL, at zero cost to the KNDL partners, will be valuable in identifying fault trends, improving reservoir definition and improving our understanding of the Kiliwani North and South structures.

Charles Santos, Executive Chairman of Aminex commented:

"We are pleased with Orca's announcement of their seismic contract award and timeframe for the acquisition of their 3D survey. The incursion into the KNDL should provide valuable data to improve structural mapping and refine the prospectivity of the Kiliwani North and South structures"
