Summary One of the ways to improve the mining and geological work at placers is a wider application of geophysical research, the role of which is currently clearly insufficient. We propose the complex of geophysical investigations to solve problems arising from prospecting gold deposits of various morphogenetic types. Depending on the tasks, it may include georadar …

This book provides the basic know-how and guidance to effectively exploit non-destructive geophysical technologies and apply them in the underground mining environment to optimise mineral extraction and to contribute to safer mining. The effective application of these technologies can enable a better understanding of the unseen orebody and the surrounding …

Ore mining fundamentally depends on the definition of its tenor and volume, something extremely complex in disseminated mineralization, as in the case of certain types of deposits of gold and ...

In areas where gold is known to occur in certain lithologic units, the geophysical logs can be used to map lithology. The use of multiparameter borehole geophysics to map lithology and to detect alteration associated with gold mineralization is illustrated using examples from boreholes in the Kirkland Lake and Hemlo mining areas.
