The map in figure 2 above, shows the simplified geology of the area under study showing the predominant rock units within the License area. The local geology shows five major rock types in the license area which can be broadly categorized into two ie Sedimentary Basin and Basement Complex. The five units are the Sandstone, the Migmatite gneiss, the Schist, the Amphibolite and the Pegmatite.
The sandstone unit is the sedimentary component of the geology which is part of the Nupe Sandstone. Generally, they are form hills of a tabular structure and ferruginous in nature. And this forms a sharp boundary with the Basement complex which is made up of the Migmatite gneiss, Schist, Amphibolite and the pegmatite. Within the schist and the gneisses are quartz veins and veinlets.
