Artisanal and small-scale mining methods and the …
The alluvial mining method is done in placer deposits or waterlogged areas where there are alluvial gold deposits, usually in a low-lying area or at the riverbeds. For the initial phase of extraction of alluvial gold deposits in low-lying areas, miners clear the vegetation and then excavate the soil to reach the gold-rich layer (Aryee et al ...

Gold Potential of the Maya Mountains
It produces fine and coarse alluvial gold including nuggets weighing between 0.25 ounce and 1.1 ounces. Total production for the period 1999 to 2008 was approximately 2,300 ounces with nearly 3/4 of this amount produced over the last two years. The alluvial gold (see figure 2) is derived from high-grade free gold mineralization (up to

Alluvial gold part 1: gold panning
Alluvial gold is gold that has been freed from its host rock and ended up where it is after having been moved by water. Examples would include modern river and creek gravels, fossil tertiary river beds and terraces, as well as modern and ancient beach deposits. If you've ever panned for gold, you've almost certainly panned alluvial gold.
