«Gold mining involves the science, technology, and business of the discovery of gold, in addition to its removal and sale in the marketplace. Gold may be found in many places, most commonly rock but even sea water; in very small quantities. More often it is found in greater quantities in veins associated with igneous rocks, rocks created by heat such as quartzite.»
