Geophysical Survey Over The Elizabeth Bay Mine, Namibia

It was decided that geophysics could play a significant role in mapping the<br>diamondiferous aeolian deposits at Elizabeth Bay. The emphasis was to derive<br>more from the geophysics than determining orebody thickness and the occurrence<br>of day, but also to extract information on the degree of cementation of the<br>deposit to assist mine geologists and engineers in mine planning. A detailed<br>electrical survey was carried out, followed by borehole logging and seismic<br>refraction work. Accurate geophysical models of the orebody were achieved.
