The program for the GAC short course “Geophysics in Mineral Exploration: Fundamentals and Case Histories” included 14 presentations relating to geophysical methods applied to mineral exploration. This text is the accompanying volume of short course notes, comprising ten papers drawn from the program. Four provide introductory, yet reasonably comprehensive, texts on the fundamental principles of the electromagnetic, magnetic, gravity and seismic reflection methods including commentary on their application to exploration. A fifth paper, that deals with exploration of volcanogenic massive sulphide (VMS) deposits, examines the geophysical responses of such deposits as imaged by each of the aforementioned methods and also by radiometric surveys. Case histories are presented for the electromagnetic and gravity techniques in two separate papers: one uses the example of the Voisey’s Bay nickel deposit (electromagnetic), and the other includes several different deposit types (VMS, manganese, uranium) in Canada, Australia and Portugal (gravity). In addition, the contributions of electromagnetic, magnetic, and gravity surveys to the discovery of the Kudz Ze Kayah massive sulphide deposit in Yukon, and of magnetics, in particular, to the discovery of more than one hundred kimberlites in NWT are outlined in two other papers. The final paper illustrates the utility of borehole geophysics in subsurface mapping using the example of the McConnell nickel deposit, Sudbury. This set of short course notes should also help the non-specialist to have a better understanding of the unique contibution made by each method to mineral exploration programs, an awareness of the limitations of each method and an enhanced degree of comfort with geophysical vocabulary.
