In Colmenar del Arroyo, In the West of the madrid Community. In the North of the town, past the Enebro.

As the cleanings are on a private property, you’ve to ask in the village for the landlord of the parcel (city hall or library).

The deposit is a fluorite vein, with galena.

Worked until an unknown date to the 70s.

I have not found information about this mine, but there seems to be a principal pit with some extensions.

Clearings follow a NE / SW axis, and have been moved recently.

Crystallized pink and yellow fluorite sometimes with phantoms. Galena is found massive and in grains in the matrix.
