Gulch gold. Gulch gold is the coarsest that exists in any part of a river system. If nuggets (pieces of gold weighing more than 0.1g) are present, they will mostly be found in gulches (narrow ravines), provided suitable traps are present, such as irregular bedrock.In gulch alluvium, the vast majority of the gold will be found on, or in crevices within, the bedrock.

1. Introduction. In 2020, global gold production was estimated at approximately 3478 tonnes (World Gold Council, 2021), where Artisanal Gold Mining (AGM) was responsible for 10–20% of this production (Fritz et al., 2017; UNEP, 2021), with an upward trend due to high market prices of the metal (Fritz et al., 2017; Hewitt, 2019) and lack of employment …

Alluvial deposits must be considered the easiest to start with, as the only piece of equipment you need is a gold pan, Metal detecting, on the other hand, has a steeper learning curve, and in many states, it's simply easier to find alluvial gold than eluvial or residual deposits. The by far most mined placer deposits are alluvial placers.
Alluvial gold is found beneath the surface at the bottom of a creak or stream. Alluvial gold mining is the process of extracting gold from these creaks, rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground mining. ...

Phase 1: Residual to Eluvial to Alluvial Deposits As soon as the gold has eroded from the main lode, we refer to it as residual gold. As long as it doesn't move too long from the original source ( a couple of feet or so), it goes under this name. However, as soon as the gold starts to move from the original source, it's called eluvial gold.
