Shannon (Au)
The Shannon structural corridor encompasses a broad region to the northeast, north and northwest of the Jebel Ohier project area. The approximately 4 by 6 km wide zone is defined by a northwest to east trending structural grain and comprises strongly deformed andesititic volcanics and gabbroic to intermediate intrusions, as well as late-stage granitic-aplitic dyke swarms. The zone is host to numerous occurrences of steeply dipping and discontinuous en-echelon quartz veins considered to represent ‘orogenic’ style gold-only systems. Where exposed by artisanals (who typically mine the highly ferruginous pinch-and-swell systems to the water table at depths of 50 – 60m), the laminated to massive veins host chlorite-carbonate and ex-sulphide-rich nests of nuggety (free) gold and are typically associated with narrow sericite-chlorite selvedges in sheared host rock. The occurrences tend to be spatially coincide with zones of strain partitioning, rheological gradients and pressure shadows within the regional-scale stress field. Results from reconnaissance trenching and rock sampling at the newly identified ‘Shannon anomaly’ situated approximately 5 km northeast of the Jebel Ohier project area in mid-2018 are pending.enetic) carbonates, the depositional setting for the Red and White Wadi area is considered to be an emerging marine to sub-aerial back-arc system. The presence of epithermal-style veins and primary copper mineralization in propylitic-altered andesites above a strong elongated geophysical anomaly at Red and White Wadi points to the possibility of an intermediate (porphyry) intrusion at depth. Results from a reconnaissance RC drilling campaign in early 2018 are pending.
