Zn-Pb-Fe stratiform deposit in Ordovician schists, quartzites and limestones, and Silurian black slates. The primary mineralization is highly modified after Hercynian regional metamorphism and tectonics.
An abandoned gallery and some dumps in the Margalida river valley, 1500 m altitude, are accessible across a mountain track 3 km to the east of Bossòst village. A project to habilitate the mine for tourist visits is now under study by the Autonomous Government of the Aran Valley.
