According to legend the El Teniente mine was discovered in the 1800s by a fugitive Spaniard official, with exploitation beginning in 1819. The best ore was mined manually in what would be called the Fortuna sector, and transported by animal. In 1904 William Braden (an engineer from New York) and E.W. Nash formed the Braden Copper Company, built a road for carts, and a concentrating plant. Chileans referred to the large scale mining operation as La Grande Mineria
