Apr 08, 2020· Ocean waters do hold gold, but it's difficult to say exactly how much. If you were hoping make your fortune mining the sea, consider this: Gold in the ocean is so dilute that its concentration is very small. One study found there is only about one gram of gold for every 100 million metric tons of ocean water in the Atlantic and north Pacific.
Gold is found widely diffused in nature even though it is one of the scarcer metals. Very commonly, gold occurs as the native metal encased within quartz. Sometimes the gold is in a finely divided state, sometimes in particles of considerable size, as nuggets, grains, scales, plates, threads and wires in
Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth’s crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions nuggets of native gold weighing up to 50 kilograms are found—the largest having weighed 92 kilograms.

A placer deposit is a concentration of a natural material that has accumulated in unconsolidated sediments of a stream bed, beach, or residual deposit. Gold derived by weathering or other process from lode deposits is likely to accumulate in placer deposits because of its weight and resistance to corrosion.
