Lineament study over Hawal Basement Complex has not been fully mapped out for mineral exploration to generate revenue and employment. The study which was carried out using upward continuation filter, first and second vertical derivative filter, analytical signal filter, and Euler deconvolution filter were interpreted. It shows that the Basement Complex has high magnetic intensities with multiple fault lines, and three major trend directions of lineament NE-SW, NW-SE, and E-W respectively. The analytical signal filter gives additional evidence that there is tectonic control on the emplacement of these basic rocks (Younger basalt and Basalt). Their emplacement utilized pre-existing fractures or lineaments in the Precambrian Basement Complex and correlate with major river courses/foliation trends. These fault zones discovered around areas like Meringa, Biu, Shaffa, Shani, Song, and environs may serve as hosts for mineral exploration.
