2011-3-3 Alluvial is a term that refers to soil sediments and the various sand, silt, gravel, clay or other deposited matter left behind by flowing water. “Alluvial gold” refers to the type of gold dust found in that kind of soil. When the beds of rivers or streams are scooped and panned for gold dust, the product is referred to as alluvial gold.
2013-8-23 On the basis of estimates of alluvial gold resources made by previous researchers, a series of commercial placer deposits, non-commercial deposits, and permissive areas have been identified in the North Takhar AOI. The Samti and Nooraba-Khasar-Anjir deposits were the focus of numerous prospecting expeditions by Soviet geologists and are considered to be commercial in nature, while the Kocha deposits, not as heavily sampled and less mineralized, are considered to be permissive. The Samti placer deposit lies along the middle span of the Panj River (fig. 3) and is situated in the Panj Valley between the mouth of the Varichi stream and Khasar River valleys. It is about 8 kilometers (km) in length and varies from 900 m to 1.7 km in width (Galchenko, 1972). Previous estimates of gold resources throughout Samti were calculated to be 30,062 kilograms (kg), with the average content throughout the entire mass of alluvium calculated to be 408 milligrams per cubic meter (mg/m³) and the average depth of the mineralized alluvium
Fine gold and small nuggets Can be transported many kilometers from source of gold. Can be ancient alluvial gold deposits in ground lifted high above current stream levels. Large nuggets, may be closer to primary gold source. How is this type of gold transported. Moved by water through gullies, streams, creeks and rivers.

Magnetic fractions were removed with a bar magnet, before the gold recovery (Clark 2010; Mboudou et al. 2017).The weight of gold was divided by the in situ volume of samples to obtain the gold grade in g/m 3 (Rae et al. 2009).The mean total section grade (TSG) was kept

The Leadhills area has had a long history of alluvial gold working, since at least 1510, and probably much earlier, but few bedrock sources of mineralisation have been located.
