Uranium mine.

Mining concession no.127 "Quarta Feira", registered on 20-03-1879 [Cu-U mine as per LNEG database].




A exploração mineira de Quarta-Feira terá começado na época dos Romanos e prolongou-se até finais do século passado. Das três minas – Bica, Carrasca e Valdarca –, foi explorado urânio, rádio e plutónio. A Bica, uma das mais conhecidas, fechou em 1961 e foi reaberta em 1974. Esteve ainda em laboração até aos anos 90, por iniciativa da ENU (Empresa Nacional de Urânio). Actualmente, a antiga exploração mineira, propriedade da EDM (Empresa de Desenvolvimento Mineiro) é vigiada por um funcionário que todos os dias liga as bombas que retiram as águas do interior dos poços e procede ao tratamento das águas com cal e cloreto. As águas são depois encaminhadas para duas represas situadas no exterior e, após o processo de decantação, são enviadas para o lençol freático.
