The major ores of gold contain gold in its native form and are both exogenetic (formed at the Earth's surface) and endogenetic (formed within the Earth). The best-known of the exogenetic ores is alluvial gold. Alluvial gold refers to gold found in riverbeds, streambeds, and floodplains.It is invariably elemental gold and usually made up of very fine particles.
Gold ore can be mined from concentrated gold deposits in the Living Rock Caverns.Concentrated gold deposits yield five gold ores at once unlike normal gold rocks.

Limestone is a sedimentary rock made up of the calcium-carbonate shells of tiny, long-dead marine animals. The convective flow patterns you see in Cream of Wheat and in gold concentration processes are called hydrothermal cells. For gold these cells can be vast in size, stretching more than 10 kilometers across.
