The mine, established in 1834, dominated the economic, social, and political life of the neighboring town of Novo Lima. The company imported 150 British families to Brazil to work for the company. The mine was photographed by Augusto Riedel during an expedition into the interior of Brazil with the son-in-law of Emperor Pedro II, Luis Augusto, Duke of Saxe.
