“…The matrix proposed by Tichauer & De Tomi [ 34 ] measures the level of compliance of mineral exploration programmes with industry best practices. This matrix is composed of 10 guidelines, based on the directives for mineral exploration established by the Canadian National Instrument 43-101 (NI 43-101).…”

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.

“…A Eletrorresistividade é um método geofísico no qual correntes elétricas artificialmente geradas são introduzidas no solo e, em superfície, medidas de diferenças de potencial são realizadas com a finalidade de mapear a distribuição de resistividade em subsuperfície (Kearey et al, 2009;Dentith e Mudge, 2014). Consiste em um método elétrico bastante popular em decorrência, sobretudo, do baixo custo, quando comparado a outros métodos geofísicos, e da eficiência demonstrada em estudos de diferentes naturezas, tais como: estudos hidrogeológicos, de geotecnia, investigações de contaminação ambiental, exploração mineral, arqueologia, entre outros (Griffiths e Barker, 1994;Gallas et al, 2005;Brunet et al, 2010;Di Maio et al, 2011;Tichauer et al 2014;Gunn et al, 2015;Martinez et al, 2017).…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
