It’s fairly uncommon to hear about alluvial gold-mining companies, but one example is Guskin Gold (OTCQB: GKIN), which is engaged in gold exploration and alluvial mining in Ghana. Loose gold-bearing sediment is understandably the preference for artisanal miners, while consolidated deposits require the capital and force of mining companies. Conversely, when the gold-bearing sediment is consolidated, gold concentrations are higher, but extraction is more complex, with drilling and blasting required to remove overburden. However, such deposits tend to have low gold concentrations. When this gold-bearing sediment is loose (gravel, for example), separation is easy. A variety of alluvial mining techniques were used over this time, but all relied on the same premise: using water to wash gold-bearing sediment. Alluvial mining for gold dates back a long time - the Romans produced gold in this way, and in the 19th and 20th centuries, alluvial mining was made famous by the California, Klondike and Colorado gold rushes, among others.
