Abstract

In the Danko Wasagu area of southern Kebbi, Nigeria, limited subsurface information has hindered the
identification of mineralization potentials, particularly due to the complex geology, variable structural
trends, and rugged terrain, which can be guide to the discovery of economically valuable minerals,
enhance mining activities, and ultimately contribute sustainable economic development within the region.
This study utilizes aeromagnetic data to assess potential mineral deposits and unravel the structural
evolution of the area through First Vertical Derivative, Analytical Signal and Source Parameter Imaging.
The result revealed that contacts, fault and edges were delineated on both filters. The shallow depth to the
magnetic sources was 118.8 to 170.0 m while high depth range 200.4 to 508.5 m from the source
parameter imaging. The qualitative analysis of the data shows the contacts and faults trends on Northeast
(NE), southeast (SE) and southwest (SW) direction and its well pronounce by analytical signal and
lineament maps. The structural trends in the Danko Wasagu area suggest high potential for economically
important mineralization. Faults, folds, and contacts likely control the concentration of mineral deposits.
Mapping these structures can guide efficient exploration and support sustainable mineral development.
These findings offer important guidance for future mineral exploration and structural mapping in
comparable basement terrain regions.
