Mina da Toca do Mocho, Cercal (Cercal do Alentejo), Santiago do Cacém, Distrito de Setúbal, Portugal
Old iron and manganese (Fe-Mn) mine (?-2000).
Mining concession no. 618.
Some data (LNEG): Quartz vein and iron and manganese oxides, with an average direction of N50ºE, dip of 45º to 65ºE, extension of 3 km, and thickness greater than 4m. The wall consists of quartz reaching a thickness of 15m, barite is frequent in the ceiling up to 2m thick, and in the central part occurs the useful Fe-Mn mineralization with an average thickness of 4m, locally reaching 12m. To the northeast, where the Rosalgar vein ends, impregnations of Fe-Mn in the shales of the Lagar da Boavista Ridge occur.
LNEG: Filão de quartzo e óxidos de ferro e manganês, com direcção média N50ºE, pendor 45º a 65ºE, extensão de 3 Km e possança maior que 4m. O muro é constituído por quartzo que atinge 15m de possança, a tecto é frequente a barite até 2m de possança e na parte central ocorre a mineralização útil de Fe-Mn com 4m de possança média, alcançando localmente 12m. A nordeste, onde termina o filão do Rosalgar, surgem as impregnações de Fe-Mn nos xistos da Serra do Lagar da Boavista.
