Further, gold is always mechanically mixed with, or entrapped in, large quantities of other minerals. Veins of Gold Ore. Veins of gold bearing ore occur most commonly in cracks and fissures in igneous rock. It is thought that the gold and its associated minerals are precipitated from superheated fluids forced upward from the depths of the Earth

mineral is generally defined as any natural accruing substance of definite chemical composition and consistent physical properties. An ore is a mineral or combination of minerals from which a useful substance, such gold, can be extracted and marketed at a price that will recover the costs of mining and processing, and yield a profit (Encarta 2001).

Marine minerals. Natural gas and oil have been extracted from the seas for decades, but the ores and mineral deposits on the sea floor have attracted little interest. Yet as resource prices rise, so too does the appeal of ocean mining. The excavation of massive sulphides and manganese nodules is expected to begin within the next few years.
