- Linear structures correlating with the known baryte mineralization at Vein 17 have been outlined from the gravity and EM methods.
- Suspected mineralized veins are characterized by low conductivity responses
- Barite mineralization is magnetically transparent.
- The thin nature of some of the ore bodies might make them unsusceptible to geophysical detection
- Exploration efforts are expected to be focused around the linear structures.
Generally and across the trough, the structural successions that played dominant roles related to mineralization are as follows:
- Mineralization is related to the folding episodes that created anticlines and synclines especially in the Upper and Middle Benue Troughs. The Axes of the anticlinal axes that runs through the axis of the Benue Trough the Lamurde and Keana caused by a Northwest Southeast compression are similar.
- The later phases of these compressive flexures are accompanied by faulting and fracturing which were later filled by fluids.
- The fractures which vary in orientation and possibly favourability for mineralization are also linked to large scale strike slip faults. In the Upper Benue Trough, these strike slip wrench faults are responsible for creation of small sub basins. In the Middle Benue however, faulting have been mapped but at a much smaller scales. Vein type deposits are restricted within such fractures accompanied by extensive silicification.
- The trends of the baryte veins define three major axes:
- The 090° – 120° (E-W) trends, dominant especially in the highly mineralized Azara Zone.
- The 170° – 010° (N-S) trends which appear to be dominant in the Lower Benue Trough, possibly caused by the NW-SE compression
- The 140° – 160° (NW-SE) trends whose age relationship with possibly succeeding phase of E-W is not well understood. They occur widespread across the entire region.
