There is no luxury of conducting an unimpeded wide-area survey for this housing Estate, as it is built up almost entirely. Therefore, the constrained area to be surveyed necessitated the adoption of the "electrical drilling," or vertical electrical sounding, mode of the geoelectrical method to satisfy the client's inquiry. Aim: To carry out a purpose-specific survey to pinpoint the best location in a built-up property at the upmarket Lawu Estate that would be suitable for a drilling regime targeted for household consumption. The specific objectives are to determine the subsurface layer structure, to identify fracture zones with potential for water accumulation, and to estimate the depths of potential aquifers. Methods: The survey crew reconnoitered the study area to georeference locations for the VES survey within the 30 m x 20 m lot. Owing to the extensive build-up at this lot, only a four-point traverse along the 30-metric dimension of the building's frontage was demarcated in the northeasterly direction, thereby limiting the survey crew's desire to define an appropriate survey grid. The VES data acquisition followed the "traditional" sequence of Schlumberger array layout measurements, in which the current and potential probes are maintained at the same relative spacing and the whole spread is progressively expanded about a fixed central point. Results: Log-log and pseudosection plots were generated from the acquired data, from which the conventional three-layer structure is deciphered, with a desired 193 Ωm for VES Station 4 at the third layer. Discussion: The acquired and processed data for this study were subjected to a suite of empirical rules-of-thumb procedures for interpreting VES data in the Nigerian Basement Complex geological province, with VES Station 4 showing the most encouraging 100% result. Conclusion: Drilling to a depth of 100 m at Station 4 is recommended based on the identified fractured basement at this depth.

Aims: To replicate and complete macroscopic and microscopic analyses of outcrops along the vestige of the Kazaure-Karaukarau-Kushaka-Ilesha Schist Belt, as well as to conduct a petrologic investigation of the percentage occurrence of schist rock-mass north of this discerned schist belt. Methods: The macroscopic-lithologic study proceeded by classifying observed outcrops at the 11 coincident groundwater-prospect/outcrop locations determined from that previous study by their physical attributes. The microscopic-petrographic investigation proceeded by subjecting rock samples collected during the concurrent macroscopic-lithologic survey phase to thin-section analyses. For the macroscopic-petrologic phase investigation, outcrop locations to the north of the Belt were classified on the basis of their observable characteristics. Result: The lithologic-investigation phase of this study reveals a higher number of outcrop rock samples identified as “granite” compared to schist based on textural and observable surface characteristics. The petrographic investigation of these outcrop rock samples reveals a higher occurrence of schist than of granite. The petrologic investigation phase reveals no presence of schist outcrops in the area north of the discerned Belt. Discussion: Thus, a stronger argument has been further presented that the discerned rock-mass diagonal of the previous standalone macroscopic-lithologic study is actually the Kazaure-Karaukarau-Kushaka-Ilesha Schist Belt. Conclusion: It is recommended that the Federal University of Technology, Minna, concentrate efforts on this rock-mass diagonal named “Jonahite” and its northeast-southwest extensions through the University’s landholding in order to explore for groundwater and gold-mineral resources, schist being the ideal repository hostrock of sustainable groundwater and gold deposits in the Nigerian basement complex geological province.

Abstract: The recognisable faulting regime at the southern half of the 8 km2 Phase II Development, Gidan Kwano Campus, is the vestigial northeast-southwest cross-country lineament that defines the Kazaure-Karaukarau-Kushaka-Ilesha Schist Belt. This belt of schist lithology of circa 800 m width and some 700 km length is “sandwiched” between a dominant granite mass to the northwest and southeast with some prominent showing of gneissic rock-mass at this southeast plain. A route of inquiry as part of the endeavour to create a purpose-specific corpus of geo-centric information for the Phase II Development leads to the question of the presence of continuous east-west or west-east faulting regimes as subordinate zones of permeation within the main NE-SW-trending lineament. The aforementioned “route of inquiry” centred on validating the conclusion drawn with respect to the hydro-centric nature of neighbouring principal survey stations along the 12th cross-profile of the half-scale 4 km2 areal extent that is the southern Phase II Development. Whilst a core vertical electrical sounding study at this half-scale 4 km2 areal extent placed stringent constraint on conclusions that can be reached on hydro-centric prospects, it is observed that it is within the realm of plausibility that a 2000 m length of west-east faulting signature traverses the 12th cross-profile. It is thus recommended that a suite of constant separation traverse and very low-frequency electromagnetic survey be carried out along the 12th cross-profile to test if this is a “wet” fault-line for its entire west-east length. Also, series of corresponding cross-profiles north and south of the 12th cross-profile should be investigated in the format that is posited.

Geospatial identification of built-up structures within Phase I Development along the Kazaure-Karaukarau Kushaka-Ilesha Schist Belt, trending through Minna town and its outlying districts, constitutes the veritable reference material desired in this regard. Methods: This study began by segmenting the area of study for ground=based and remotely sensed attribute mapping, using the key reference map from a previous study as the area of-study guide. A handheld Garmin GPSmap78® global positioning system unit and a standard smartphone with a built-in camera were the key equipment used for the fieldwork. Polygonal-format georeferenced coordinate information was collected at conveniently detached buildings, beginning with the cluster of residential homes at the Staff Quarters, for the ground-based survey. Result: Nine of the ten built-up structure clusters on the path of the Belt in Phase I Development were mapped for this study, as well as six neighborhoods in the Minna built-up area beyond Phase I. The nine clusters occupy almost 40% of the circa 2 km2 areal extent of the Phase I Development. The belt's trend and structures were north-northeast. Discussion: The nine cluster structures in Phase I and the six neighborhoods of Minna identified in this study have been determined to align with the path of the belt. Conclusion: Having now determined that the trace of the belt exits the Campus at the northern sector of the Gidan Kwano village and trends in a long arc beyond the town, this study becomes the desired reference material to be archived and consulted for information relating to gold exploitation in the Minna Area geological province.
