Resistivity model used for the 3D synthetic forward modelling study. The red box shows a birds eye view of the six lines, with each black square representing one site. The orange dashed box shows the respective base sites (\({{\mathbf{E }}}_{{B}}\)) used for each line, and the dashed purple box shows the measured sites (\({{\mathbf{E }}}_{{M}}\)). The location of the red conductive block at 3.6 km depth is shown
