Possibly of interest; found a small museum a few weeks in a village called Saint Veran (which is the highest village in France populated all year round) about the local copper mine.
The plan shows a typical metal mine over five levels; and a range of information boards about the history, modern operation, mineral processing and some good archive photographs. No idea about access, but if it's possible it would be nice to to try to visit in the summer. The boards listed the numbers of some other local mines where trips can be arranged.
The text should be readable in the supersize versions of the photos.
