The daily rituals of two mining communities are observed in this strikingly visual and unsparing portrait of life and work in Bolivia’s altiplano, at an altitude of fourteen thousand feet. More than ten thousand miners still excavate the slopes and tunnels of the richest silver field in mining history, Cerro Rico (Rich Hill), an enormous conical mountain in the Andes that towers over the city of Potosí. The miners’ lives offer a strong denunciation of the hardships and alienation inherent in industrial work inside the mines, underscoring the historical impact on the native population created by global demands for earth’s wealth. Shot in iconic Potosí and Cerro Rico and, as a counterpart, in the Arctic-looking plains of Salar de Uyuni, where salt is extracted daily and where half of the world’s lithium reserves remain untapped.
