For millions of years these agents of change have been mining gold and depositing it into alluvial deposits. An alluvial gold deposit is a concentration of gold that is put in place by the natural action of the flow of water, where the heavy gold settles out of the moving water, while lighter material like quartz is washed farther downstream.
