Does anyone have any information about mines in Switzerland?
I know of 4:
The Rock Salt Mines (Mines de Sel) near Bex in the Rhone Valley
The Zinal Copper Mine in the Val de Zinal (the upper part of the Val d' Anniviers) NW of Zermatt
Trachsellauenen (Iron Mines in the Lauterbrunnental - the same valley as the Wengen Ski resort)
Silberberg Lead Mine on the S side of the Landwasser Valley near the village of Wiesen, W of Davos.
Any others?
