Abandoned hematite mine, the most important one that was exploited in the municipality. Its production definitively ceased in the late 1980s. Located two kilometers north of Borobia and at south of Monte de La Hoya, it is accessed from the Hermitage of Virgen de Los Santos. Currently the open pit, conical and almost 300 meters in diameter at its highest, is flooded, reaching the water a depth of 50 meters. Nowadays the place is an artificial lake with tourist and natural interest.

Situada a dos kilómetros al norte de Borobia y al sur del Monte de La Hoya, se accede desde la Ermita de la Virgen de Los Santos. Actualmente la corta, de forma cónica y de casi 300 metros de diámetro en su parte mas alta, se encuentra inundada, alcanzando el agua una profundidad de 50 metros. Actuamente el lugar es un lago artificial con interés turístico y natural.
