Lithological and alteration mineral mapping for alluvial gold
Gold is mainly hosted in alluvial and placer deposits (Mestraud and Bessoles, 1982; Milesi et al., 2006). Primary gold deposits are generally associated with Archean to Paleoproterozoic formations, which are typically hosted in late-tectonic granites associated with quartz veins and dolerite (Mestraud and Bessoles, 1982; Kpeou et al., 2020).

Evaluating an Alluvial Gold Deposit | Mining FAQ'S
The gold can be hand picked, or carefully panned to purity, or better still the final concentrate sent to a lab for Total Fusion assay to give the grams of gold present. The oversize rock is then screened on a 15mm screen by hand and the -15mm is fed to a GoldJigga hand jig to recover any nuggets.
Gold | Geoscience Australia
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
