As a geologist who works for a mine, I highly recommend not entering abandoned mines. Yes, there are cool things in them sometimes. But we seal them for a reason. There are often unexpected pits/shafts, unstable rocks, dangerous animals, and plenty of other dangerous things. The process of entering an abandoned mine to collect samples takes weeks of slow and careful work by professionals.
