A gold and silver mine, worked from 1935 until 1983. The deposit was in altered volcanic rocks (propylitized Miocene andesite). A roadcut next to the mine was briefly famous for zeolite specimens (including yugawaralite crystals up to 3cm long), but is now completely covered with concrete to prevent erosion.
21 valid minerals.
