“…Moreira et al [22] show how the application of resistivity and IP supplied data for modelling of a gold deposit. Coelho et al [23] aim to evaluate the potential of resistivity tomography as a prospecting tool for supergene ore. Martins et al [24] demonstrate how resistivity and IP can assist on morphological modelling in a limestone mine. Martins et al [25] contribute to mineral exploration in small-scale mining by showing how resistivity and IP can provide important information for geological modelling quickly at a low cost and can reduce, by 30-50%, the amount of drill holes that do not find ore. Moreira et al [26] also recommends resistivity tomography for mineral exploration because of the quickness of the procedures and the reduction of project costs.…”

Small-scale mining usually operates under high geological uncertainty conditions. This turns mine planning into a complex and sometimes inaccurate task, resulting in low productivity and substantial variability in the quantity and quality of the mineral products. This research demonstrates how the application of a novel methodology that relies on traditional and low-cost geophysical methods can contribute to mine planning in small-scale mining. A combination of resistivity and induced polarization methods is applied to enhance mine planning decision-making in three small-scale mining operations. This approach allows for the acquisition of new data regarding local geological settings, supporting geological modelling and enhancing decision-making processes for mine planning in a timely and low-cost fashion. The results indicate time savings of up to 77% and cost reductions of up to 94% as compared with conventional methods, contributing to more effective mine planning and, ultimately, improving sustainability in small-scale mining.

“…The use of the ERT technique, by itself, does not allow assess concentrations of materials; however, it provides the location of soil dots by which variations of electrical resistivity values are determined. This study proposes an innovative use of the 2D-ERT technique, compile with an interdisciplinary confluence, between other field techniques and laboratory tests, to be able to take advantage of the physical property of electrical resistivity in the analysis of the concentration of pollutants within the materials assessed in the subsoil (Coelho et al, 2020).…”

Cadmium is a toxic non-essential metal for almost all living systems. It is one of the biggest challenges for farmlands and the food chain because of its toxic effect on human health. This research aims to determine the Cd content in soils, litter and cacao beans, following the Cd fluxes within each cacao system using the two-dimensional electrical resistivity tomography technique. The study was carried out in four farms located in the Magdalena basin in Antioquia, Colombia. The farms showed a heterogeneity in relation to cacao cultivars, altitude, topography and geology. The soil cation electrical capacity, pH and soil organic matter levels, as well as the Al, Al 3+ H + , Ca, K, Mg and P contents were measured at different depths. Moreover, the Cd content was correlated to the resistivity values of samples taken in situ using ERT. Soil Al 3+ H + and the altitude of the farms fitted as the best predictors of the beans' Cd content. Furthermore, the Cd content in soils from the assessed farms ranged between 1.22 and 2.03 mg kg −1 . The Cd content in cocoa beans ranged from 0.07 to 1.44 mg kg −1 , with a value of 0.40 mg kg −1 on average. The resistivity values obtained in field showed a high correlation with the soil Cd content determined (R 2 = 0.82). The predictive tomography plots highlighted topsoil Cd dynamics between litter, amendments and fertilizers. Therefore, these results underlie the utility of the combined geophysical techniques and soil chemical properties including the analysis of fertilizer amendments to improve the understanding of Cd dynamic.
