The geology of the Mundri Licence is dominated by the Basement Gneiss Group, undifferentiated in Vail’s map of 1974, but which in a later map (GMRD – Khartoum, 1981) has differentiated to include the Basement Schist Group. This is an important economic consideration, as it is the schist or greenstones which generally contain or are spatially related to the gold deposition. The map above shows 3 such gold occurrences.
The next feature of significance to epigenetic mineralisation in general is the major fault line, the Aswa Cataclastic Zone (“ACZ”), which has long been the focus of economic geological interest. There are 6 gold occurrences along the Aswa Cataclastic Zone in South Sudan to the south of the Mundri licence (the Luri area). The ACZ trends north-westward from Mount Elgon, a volcano on the Kenyan border, right through Uganda and into Epic.Ex’s Mundri licence in South Sudan. Far more would be known of this extraordinary structural feature if work on it in South Sudan was not delayed by the civil war in Sudan, or by the activities of the Lord’s Resistance Army in northern Uganda. No such impediment exists today to prevent exploration work being carried out on this highly prospective structural feature in the Mundri licence.
