The El Abra mine is a large copper mine located in northern Chile in the El Loa province. [2] It is operated by American mining company Freeport-McMoRan, who owns a 51% stake in the mine, [3] with the remainder owned by the Chilean state-owned Codelco. [2] The stake owned by Freeport-McMoRan originally owned by Cyprus Amax Minerals and Lac Minerals until Phelps Dodge acquired Cyprus Minerals and Lac minerals was absorbed by Barric Gold in 1994. [4] These two companies had won a bid to engage in a partnership with Codelco. [5] It was then owned by Phelps Dodge until 2007 when Freeport-McMoRan completed a $25.9 billion acquisition of Phelps Dodge. [6] [7] The mine holds the The Copper Mark environmental certificate. [8]
The development of the previously unexploited El Abra ores as a joint venture was enabled by the law Ley N° 19.137 of 1992 which allowed Codelco to sell its assests with the previous approval by the Chilean Copper Commission and allowed the company to form joint ventures. [9] In the bid process nine proposals were evaluated by Codelco which settled for the joint bid of Cyprus Minerals and Lac Minerals. [5] The bid process suffered however from an overestimation of resources by 14% which caused the winning party, Cyprus Amax Minerals (renamed after a 1993 merger with AMAX Inc.) and Lac Minerals, to renegotiate the acquisition down to US$345 million from the previous price of US$405 million. Codelco reportedly did not contest the new proposed price as a matter of the precedent failed negotiations would create for future joint ventures. [4]
The mine's annual produce lies since 2016 in the range of 70 to 100 kMT copper fines. [1] Previously, from 2005 to 2015 the annual produce was in the range of 120 to 220 kMT copper fines. [1] As of 2025 it was Chile's 17th most productive copper mine. [1]
