Geophysical signatures of the gold rich porphyry copper deposits: A case study at the Dalli Cu-Au porphyry deposit

Journal of Economic Geology, 2019
Introduction Geophysical exploration is an inexpensive, fast and efficient tool to provide valuable information about the sub-surface geological complications (Dentith and Mudge, 2014). Modern geophysical methods are widely used to identify and characterize porphyry copper deposits on various scales (Holden et al., 2011; Hoschke, 2011; Clark, 2014). It
