El Dorado is an open-pit iron mine near the city of Ovalle in north-central Chile, located 98 km southeast from the port of Coquimbo.[2] A 1946 economic geology study by Carlos Ruiz Fuller and co-workers estimated the ore grade in El Dorado at 68% Fe, one of the highest in the Chilean Iron Belt.[3] The mine had its main period of activity from 1952 to 1966 under the ownership of Compañía Minera Santa Fe but mining continued sporadically until 1971.[4] The opening and successful operation of the mine in the 1950s –producing 45,000 tons of ore per month for much of that decade[5]– is considered to have paved the way for the rise of the medium-scale iron mining in Chile in the 1960s and 1970s.[6][7]
In the 2020s the mine have been operated and owned by Sociedad de Inversiones Tierra del Fuego Limitada with permits limited to extracting material from old waste rock dumps.[1][4] In connection to this activity the mining company has been accused to engage in non-authorized mining of fresh ore.[1]
