“…2D ERT has been found to be more efficient in various studies like hydrogeological study, ground water exploration, geotechnical site investigation, environmental assessment and archaeological site investigation (Abu-Zeid et al, 2004;Aristodemou & Thomas-Betts, 2000;Awang et al, 2016;Cassiani et al, 2006;Chambers et al, 2006;Dahlin & Zhou, 2004;Drahor et al, 2008;Lesparre et al, 2016;Loke & Lane Jr, 2004;Mansoor & Slater, 2007;Marsan et al, 2017;Martínez-Pagán et al, 2009;Metwaly & AlFouzan, 2013;Mojica et al, 2017;Stan et al, 2017;Yeh et al, 2002). Application of electrical resistivity imaging in realm of mineral exploration is also found to be efficient and effective (Beauvais et al, 1999;Cardimona, 2002;Chambers.…”

Evaluations of a mineral resource are necessary for mineral rights, owners and investors alike. However, for resource evaluation the detail documentation of subsurface geological spatial distribution such as lateral and vertical extent of bedrock and topsoil, hydrogeological investigation and boulder characterisation is mandatory. Boulder is hard and crystalline compact rock block, which substantial presence in a deposit highly influence the drilling equipment selection. A traditional exploration technique particularly for granite resource evaluation is drilling. But even finite number of drilling sample fails in the accurate delineation of boulders because drilling is limited to small point and rock mass is heterogenous and thus immense portion of the deposit via drilling method remain discern. 2D electrical resistivity imaging (2D ERT) technique of the study area over an area of 3.5 km 2 was accomplished by six resistivity lines using a Schlumberger protocol with inner and outer electrode spacing of 5 m and 10 m respectively. Inverted resistivity images successfully identify the existence of boulders in the area of investigation in the topsoil region; characterized by high resistivity values more than 2400 Ω.m. Whereas, only one core log (BH3) out of three reported presence of boulders. Thus, the research study presented in this paper enables us to conclude that the combined application of borehole and ERT allows us to derive that 2D ERT enhances the resource evaluation efficiency and reduces the cost considerably for underlying subsurface geological characterization.
