— Once the system has been calibrated, the results are available right after completion of logging operations at a given borehole. There are relatively few reports describing the application of PGNAA logging for in-borehole determination of copper grade (Nargawalla et al., 1977; Moxham et al., 1972). Since then, significant progress has been ...
