Alluvial gold dredging notably expanded the drainage basins of these rivers, consequently augmenting water accumulation. Moreover, diversion of river sources to distant locations for gold ore washing further contributed to the rise in water volume. Resultantly, effluents gather on the land and in abandoned mining pits.

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. Alluvial gold deposits are formed through the weathering actions of wind, rain, and temperature change on rocks containing gold.
