Gold rushes extend as far back to the Roman Empire, whose gold mining was described by Diodorus Siculus and Pliny the Elder, and probably further back to Ancient Egypt.Within each mining rush there is typically a transition through progressively higher capital expenditures, larger organizations, and more specialized knowledge.The surface outcrop of a gold-bearing vein may be oxidized, so that the gold occurs as native gold, and the ore needs only to be crushed and washed (free milling ore).The first miners may at first build a simple arrastra to crush their ore; later, they may build stamp mills to crush ore more quickly.They were highly significant to their respective colonies' political and economic development as they brought a large number of immigrants, and promoted massive government spending on infrastructure to support the new arrivals who came looking for gold.While some found their fortune, those who did not often remained in the colonies and took advantage of extremely liberal land laws to take up farming.The resulting increase in the world's gold supply stimulated global trade and investment.

The low investment, the high value per unit weight of gold, and the ability of gold dust and gold nuggets to serve as a medium of exchange, allow placer gold rushes to occur even in remote locations.

They may also progress from high-unit value to lower unit value minerals (from gold to silver to base metals).

A rush typically begins with the discovery of placer gold made by an individual.

Activities propelled by gold rushes define significant aspects of the culture of the Australian and North American frontiers.

At a time when the world's money supply was based on gold, the newly mined gold provided economic stimulus far beyond the gold fields.
