How do miners know when a mine is tapped out ? Or how they know where to mine in the first place?
In: Earth Science
I’m not sure about the first one, but for the second, a lot of what you do in looking for a good mine site is look at what kind of rocks and geological features are present. If you wanted to mine silver, you’d probably find a region known for it and then start looking for the types of rock which can hold large amounts of silver ore. If you’re looking for gold, you might follow the topography to find ancient river systems that would have deposited it in their beds.
