“…This research work also showed to certain extents the accuracy of the electrical resistivity method of geophysical prospecting when compared with the results obtained in the work of Badmus and Ayolabi (2005). This research work further showed the occurrence of vast deposits of limestone, which can be of economic importance in mining and industrial purposes.…”

“…Samples A, D and E belong to facie III because the resistivity and permeability values revealed that the limestone here is porous with grains as confirmed by Badmus and Ayolabi (2005). While sample F belongs to facie IV with the lowest value of resistivity and highest value for permeability.…”

“…This geophysical exploration was carried out to map the limestone deposit of Ewekoro formation, southwestern Nigeria using direct laboratory method via direct current power supply. This direct method approach is to complement and compare the study carried out by Badmus and Ayolabi (2005) where limestone of Ewekoro formation was delineated using Schlumberger electrode array to map both vertical and lateral extents of the deposit (Figure 1). This approach would also confirm the accuracy of electrical resistivity method of geophysical prospecting for mineral exploration as well as characterizing the various litho-facies of Ewekoro limestone (Badmus & Ayolabi, 2005).…”

Badmus et al (2006) carried out geoelectric evaluation of mica schist deposit of Area J4, southwestern, Nigeria using the direct laboratory method to characterize the mica schist into different degrees of purity for both economic and commercial purposes.…”

“…Geoelectric mapping and characterization of limestone deposits of Ewekoro formation using Schlumberger arrangement was carried out to map both vertical and lateral extents of the deposit and establish the various litho-facies changes of Ewekoro limestone [5]. Geoelectric evaluation of mica schist deposit of area J 4 south-western Nigeria was carried out using direct laboratory method to characterize the mica schist into different degrees of purity for both economic and commercial purposes [6]. Vertical electrical sounding (VES) has also been found applicable in determining the extent of inland of the gravel deposits being quarried at the bank of Otamiri River, a tributary of Imo River to estimate the reserve potential within a specified grid cell [7].…”

Vertical Electrical Sounding (VES) using Schlumberger array was employed in data collection.Data acquisition was carried out along Oyan river bank with a total of twenty-three (23) soundings. This location was divided into two zones: VES 01 -09 and VES 10 -23. Rock samples hosting specks of tantalite, tourmaline and beryl were collected from the artisan pits within the study area and taken for geochemical analysis in the laboratory. The result of geochemical analyses revealed the quality of the solid minerals in terms of mineral compositions (major, trace and rare earth elements) while geophysical field measurement revealed the resistivity values, vertical and lateral distributions and depth of the solid minerals. The range of electrical resistivity values of these solid minerals as revealed by laboratory measurement is 19.4 -31.1Ωm while that of the host rock is 10.0 -100.0Ωm as obtained from field measurements. Specks of tantalite, tourmaline and beryl were suspected to be sparsely distributed in other VES locations except at VES02 and 09, where vast deposits were suspected. Two litho-facies changes were observed and this revealed the economic values of these solid minerals. Black tourmalines, beryl and tantalite samples collected as specks within the study area were of low quality while pink tourmaline is of moderate quality on the basis of the chemical constituents contained.

The Odukpani limestone deposit has been investigated using geophysical and laboratory techniques with the aim of generating information on its spread and quality. Information generated from the analyses of twenty-six Vertical Electrical Soundings (VES) and core drilling data were used in the study. The VES data were acquired in both grid and random patterns in the immediate area of the limestone mineralisation and the adjoining areas using the Schlumberger array was adopted in acquiring the VES data in both grid and random patterns in the limestone mineralized and the adjoining areas. Cored limestone samples were analysed using the Proton Induced X-ray Emission (PIXE) method in order to determine their elemental composition and consequently quality. Both manual and computer modeling techniques were used in modeling the VES. Results show that the limestones have limited spread and have high concentration of Ca (11,200%) and K (302,400%). Mean electrical resistivity of the limestone horizon is 405 Ωm which is suggestive of a limestone deposit that is not pure but contaminated with Fe (8,620%), shaly and other contaminants. The limestone deposit is limited in both vertical and lateral extents. Thus the deposit will not favor any large scale mining operation and equipment deployed for its exploitation must be corrosion resistant type.
