Cerro Rico Wikipedia
Cerro Rico de Potosí was accidentally discovered in 1545 by Diego de Huallpa, a Quechua silver miner for Spanish invaders, while he was searching the mountain for an Inca shrine or traditional burial offering. The red mountain, now known as Cerro Rico, sits nestled between the Porco and Sucre mines, which had previously been discovered, being at lower altitudes and therefore easier to mine.
