We are currently doing a research project on how the deposition of gold in California helped shape the history of California.
We are wondering how much gold & silver is left to be mined in California. I'm assuming it's a lot but I just can't remember how much. Also, Where are most of the gold mines in use currently in California, like The Mojave Desert?
Where is gold currently being deposited around the world today? I've heard, as a geology teacher, that it's currently being deposited in the Long Valley Caldera but are there other areas in the world?
