A silicate-type nickel deposit (nickel-bearing serpentinite), formed by hydrothermal and later lateritic weathering of ultramafic rocks (peridotites). The deposit is cut by numerous pegmatitic and oligoclasitic veins which are associated with a nearby Variscan syenite massif.
The deposit, which was was mined since the Middle Ages for chrysoprase (first known occurrence), was explored for nickel since 1891, first from underground workings and, since 1935, from open casts. The mines were finally abandoned around 1980.
