SERRA PELADA, Brazil :With a voice more youthful than his 72 years would suggest, Lucindo Lima sings about the untold riches he never made in Brazil's Serra Pelada mine, a site made famous by a 1980s gold rush immortalized by the late photographer Sebastiao Salgado. "Under those mountains all our riches are hidden," Lima sings outside his decaying wooden house in Serra Pelada, a hilly district in the town of Curionopolis, in the Amazonian state of Para.
