The demand for diamonds has exceeded supply since 1999, sparking a diamond exploration boom. However, in spite of considerable expenditures, the ratio of reserves to annual production worldwide has declined consistently in recent years.

The Southern African Magnetotelluric Experiment (SAMTEX) is a regional-scale MT investigation of the deep structure of southern Africa, particularly the Kaapvaal Craton but also the attached mobile belts; it extends into northern Namibia and Botswana, on to the Angola Craton and the enigmatic Rehoboth Craton. Cratons are the ancient, relatively undisturbed
