Research was carried out both in the laboratory and at a mine to establish suitable dynamic borehole logging technologies for manganese mining based on prompt neutron-gamma and neutron activation techniques. The calibration accuracies obtained in similarly mineralized media at the mine, in dry shallow (15 m deep) boreholes of 150 mm diameter, were also about 4% Mn for the prompt neutron-gamma method, both for the entire mine and for the individual deposits at the mine. For logging based on neutron activation analysis, the calibration accuracy was less than 3.5% Mn in one area of the mine. However, the accuracy was 6.5% Mn for the calibration based on the entire mine.
