Alluvial deposits are associated with rivers and the gold occurs as nuggets or fine gold. There is no gold in the hard rock in an alluvial deposit. An elluvial deposit is one that was also deposited by rivers or water a long time ago and it may now be far from any river. Again the gold is free and there is no gold in the rocks.

Alluvial Gold Mining Technologies | Encyclopedia MDPI

Gold was primarily collected from alluvial deposits in the ancient world using gravity techniques and mercury (amalgams), which are still employed today in small-scale alluvial gold resources. Large-scale hard rock mining first employed cyanide in the 1880s to extract commodities, including gold, silver, copper, and other precious metals [ 7 ] .
