I've come across a problem. A few of my characters are miners, and I have almost *no idea* what miners actually do. To my knowledge, they find veins of rock where the ore they want (In this case, silver,) is prevalent. Then they hit the veins with picks or hammers or something to break chunks of ore-rich rocks out, haul those chunks out on a minecart, and smelt them. (The technology available is approximately similar to late 19th century, if that matters.) So... Am I close? What else do I need to know?
