Mina da Preguiça, Sobral da Adiça, Distrito de Beja, Portugal
WARNING: This mine is on a private property. The natural preservation of the surrounding area is under the responsibility of the official state entities for the protection of nature, and its control is also done by the local authorities. Some galleries in the mine host important bat communities, with very specific breeding cycles. Visits to the mining area are not allowed without prior authorization from the owners.
Fe-Zn-Pb mine, 5 km SE of Sobral da Adiça (1914/5 to 196?).
Included in the Preguiça-Vila Ruiva mining field (mining concessions 363, 628, 629, 630).
Occurrence types:
Iron occurrences - linked to volcanism – stratiform.
Zinc and lead occurrences - linked to volcanism – stratiform.
Zinc and lead occurrences - linked to supergene processes – gossans.
Geological description:
On the surface, either in Vila Ruiva or in Preguiça, iron caps occur mainly on Cambrian dolomites arranged in an anticlinorium; at depth, Zn-Pb (Ag) mineralisation occurs in tabular layers orientated N45°W, dipping 50°E, with compact ore and earthy ore pockets associated with limestones containing several impregnations of pyrite, galena, and chalcopyrite in proximity to volcanic rocks. The Zn-Pb (Ag) mineralisation is pre-orogenic. There are layers of hematitic mineralisation that are interstratified in "mineralised schists" and are independent of the previously referred to impregnations, which extend for 1,500 m (striking N60°W), with a smooth gradient and a 3 m thickness.
Main minerals: galena, goethite, hematite, hydrozincite, siderite, and smithsonite.
Morphologies: stratiform, gossan.
Host rocks: crystalline limestone, dolomites, and shales.
Local geology: Moura Anticline-Ficalho. Volcano-Sedimentary Complex.
Regional geology: Cambrian, Silurian.
Two ore bodies are recognised from the surface down to the water table (100 m deep), where the primary sulphide mineralisation is found. The sulphides’ oxidation on the surface produced a gossan zone with 40 m thickness, very enriched in zinc, which was the major target of exploration in the past. On the NE flank of the structure, exploration boreholes crossed the mineralised horizon with 20.4% Zn, 5.2% Pb, and 107 ppm of Ag. The Moura region has had a long history of mining, possibly from pre-Bronze Age times to the twentieth century.
