About Rio Tinto Plc Common Stock
The Rio Tinto Company Limited was one of the founding companies of the Rio Tinto Group conglomerate, which was responsible of the exploitation of the Riotinto-Nerva mining basin in Minas de Riotinto between 1873 and 1954. It was founded in 1873 by British capitalists to take over the exploitation of a series of sites in the Riotinto-Nerva mining basin that they had acquired from the Spanish State that same year. During the following decades, the extraction of minerals in the area experienced a major growth, with the development of various mining and metallurgical activities.
