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. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well

The California Gold Rush was a multicultural place and without the knowledge of people who knew how to mine, it may have ended much earlier. The mining techniques used in the Gold Rush evolved over time. This evolution tells a much more complex story than it seems at first glance; the change in mining techniques reveals the myth of the Gold Rush.
