The Paleogold plan is to get into production in 2022. With testing success, a mining operation can commence production within a few months and gold produced from day one. Why Invest in Alluvial Gold Exploration. Low capital investments. Alluvial or placer gold is usually found close to the Earth's surface and can thus be accessed more easily.

Gold was primarily collected from alluvial deposits in the ancient world using gravity techniques and mercury (amalgams), which are still employed today in small-scale alluvial gold resources. Large-scale hard rock mining first employed cyanide in the 1880s to extract commodities, including gold, silver, copper, and other precious metals [ 7 ].

Redcastle History. Redcastle was discovered in 1859 at the Staffordshire Flat alluvial field. The first hardrock gold discovery was Clarke's Mine in 1859 by a party of Italians and Austrians, led by Antonio Geronovitch, then named the Balmoral Diggings. 'Redcastle' a name of Scottish origin, displaced Balmoral (also of Scottish origin) in 1860.

Alluvial mining is an old technology, but it's still fairly common today. Some mining companies use the technique, though it's more often a source of income for individual laborers in areas like Africa and South America. But what exactly is alluvial mining? Put simply, it's the mining of stream bed deposits (also known as alluvial deposits) for

Since gold is extremely dense, it is easily trapped alongside other dense alluvial particles in these low-flow areas. The bits of gold found in these deposits of alluvium are called "alluvial gold.". Since alluvial gold is usually found in extremely small amounts, we have a blanket policy to not accept it at the refinery.

After a mineral-bearing soil reaches the bottom of a slope, it can be moved by stream water so that stream or alluvial placers form. Alluvial placers have played an especially important historical role in the production of gold. Indeed, more than half of the gold ever mined has come from placers, since the giant Witwatersrand gold deposits in South Africa are fossil …
