Cerro Colorado mining deposit

Cerro Colorado, popularly known as Minas del Rey Salomón, is a Spanish mining deposit in the province of Huelva, Andalusia, located in the municipalities of Minas de Riotinto and Nerva. Its main mineral reserve is copper with 822,000 proven tonnes, of which 696,500 tonnes are recoverable with the current market and profitability range of the mine. As of 24 June 2021, with 206,297 tonnes already mined, the copper mineral reserve increased to 702,000 proven tonnes. In addition to some 9.4 million ounces of silver. The Cerro Colorado deposit began to be exploited in the late 1960s, after the Riotinto mines had been taken over by Spanish capitalists. It soon became one of the main centres of mining activity in the basin, with the construction of several industrial facilities for the treatment of materials. The extraction work continued until its closure in 2001, due to the low economic profitability of its exploitation. However, since 2015 the deposit has been operational again.
