Placer mining is the by far most common mining activity practiced by hobby prospectors, as the gold doesn't need to be extracted from hard rock. Another reason is that placers often lie on the surface, and are accessible to nearly anyone using just hand tools. As a result, most of the gold that was found in the gold rushes of the 1800s came ...
