Across the southern reaches of the 8 km2 tranche of the Gidan Kwano Campus, known as the Phase II Development, fault-traces that correlate with the Kazaure-Karaukarau-Kushaka-Ilesha Schist Belt have been discerned. Thus, this study is concerned with the analysis of acquired SP data over an area of interest at the southernmost 0.4 km2 tranche of this Phase II Development. The SP survey was conducted at 5 m ground-interval for the 300 m southernmost reaches of the area of survey; this survey was accomplished by the ABEM Terrameter SAS 4000. Qualitative analysis of the SP data-field of this study proceeded by the route of producing contour maps for the four distinct depths of survey for this study and these are the 5th, 10th, 15th, and 20th metre marks. Prominent negative anomalies greater than the -100 mV mark occur at P1-1 and P14-3, although at P2-1, P2-2, P3-1, P5-1, P7-2, and P10-1 there are large negative values hovering around the -100 mV value. The fact that prominent negative SP values of the kind at P1-1 and P14-3 occur along a flat dip is indication of mineralisation. This study recommends that a detailed geological work be conducted at the locations of P1-1 and P14-3 to determine the surface characteristics of the source of these prominent negative SP anomalies. Also, induced polarisation and vertical electrical sounding geophysical surveys should be conducted as follow-up studies at these locations. This recommendation is germane in the context of the present realities of the relationships between the central government and universities in terms of making public funds available in sufficient amounts to these institutions as the government now advise that universities seek and exploit their natural endowments in order to supplement this central government’s funding. Furthermore, such follow-up studies that assuredly delineates mineral-prospect locations are worthy contributions to knowledge in this circumstance plus the positive economic benefits derivable thereof.
