Köppen climate type:
Stockwork of calcite veins, mainly millimetric to centimetric (and up to 30~50 cm in the now collapsed galleries). The veins are hosted in lower Cenomanian marl and contain arsenic sulphides. Arsenic sulphides can also be found as marl impregnations, apart of the calcite veins.
Calcian and magnesian secondary arsenates can be found, especially beside the ancient processing installation in a place where was implanted the ore storage. Some samples can be found on "anthropogenic substratum" (broken roof tiles).
Worked from 1901 to 1931.
