Traditional mining, also known as old-school mining, is a mining method involving the use of simple manual tools, such as shovels, pickaxes, hammers, chisels and pans. [1] It is done in both surface and underground environments. Until the early 1900s, traditional mining was widely used throughout the world.

Once the dredges shut down, the machinery was left behind. Many of these machines are now located at Gold Daughters in our unique Alaska museum. Some Local History

In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal..

Large corporations essentially ruled the Gold Rush and literally had the ...
