Since gold is extremely dense, it is easily trapped alongside other dense alluvial particles in these low-flow areas. The bits of gold found in these deposits of alluvium are called "alluvial gold.". Since alluvial gold is usually found in extremely small amounts, we have a blanket policy to not accept it at the refinery.

Because gold is heavier than most of the material moved by a creek or river, it can become concentrated in hollows and trapped in the bed of the river. These are known as secondary (alluvial) gold deposits and they can be worked using a gold pan or cradle. Alluvial gold deposits sparked the Australian gold rushes of the 1850's. Resources
