Placer gold mining was soon joined by hard rock mining, as prospectors followed the gold to its source veins in the mountains. Gold in some upper gravel benches north of the Blue River was recovered by hydraulic mining. Gold production decreased in the late 1800s, but revived in 1908 by gold dredging operations along the Blue River and Swan River.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Mining consists of taking rocks that contain minerals of interest out of the ground. Here, the minerals of interest in the rocks contained silver and gold. The problem the miners had to solve was getting the largest quantity of the silver and gold while taking out the least amount of rock that contained little or no silver or gold (waste rock).

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
