In modern times money matters and so the first step in mining is to find a suitably sized deposit of ore. For example, diamonds were found in Kimberley and gold ore was found in Johannesburg. These deposits were large enough to make mining for the gold and diamonds profitable. As the number and size of known deposits is shrinking, geologists (who study the lithosphere) are developing new ways ...
