The mines were nationalized in 1954 but later sold back to a private company.

, acquired the mines of Riotinto. Encountering the problem of transporting miners from their homes to their workplaces, and taking only economic concerns into consideration, they planned construction of houses where the miners had already built huts to stay overnight near the mines. Thus, the village of La Atalaya was founded in 1883. The company simply substituted more durable buildings for the huts, constructing neighborhoods in the locations the miners had already chosen. Construction began on 100 houses, each of 45 square metres (484.4 sq ft), providing only the most minimal necessities of lodging.

The company then went on to build a public plaza, chapel, grocery store, casino, school, and a Guardia Civil

 barracks. For almost a century, this was home to many of the miners, first those working in the subterranean mine and then in the Corta Atalaya open pit. The population peaked around 1910:
Year 1888 1900 1910 1920 1930 1940 1950
Population 823 1272 1472 1105 1238 1009 662

In 1970, La Atalaya had 257 buildings and a population of 823. That year, approval was received to enlarge the pit; in 1971, La Atalaya was destroyed because it was in the path of the mining.

La Atalaya was not the only townsite sacrificed to the mine. Earlier, the original location of Minas de Riotinto

After closure

As of 2007, EMED Mining owns 51% of the mine. EMED Mining has established EMED Tartessus, which is currently tasked with cleaning and restarting the mine, and Proyecto de Rio Tinto to operate it for the long term.

For some time after the mine closed in 1992, it was possible to visit the mine. EMED Tartessus did not allow the public to visit as of 2007, but was discussing the possibility of changing that.

EMED projects that eventually the mine will again employ 450 people, and that they will be spending over €130 million per year in Spain. As of September 2007, they had spent €3.5 million and budgeted another €15 million toward cleanup and resumption of operations. As of 26 October 2009, they projected that production would resume by the end of 2010.
