Successful gold mining is generally done in two steps: First is sampling or prospecting, and then, production. While some goldbearing creeks and rivers tend to have gold values dispersed throughout their entire streambeds, there is generally not enough gold to make a smallscale mining operation payoff very well.
The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined.
