Zaldívar is a 50/50 joint venture operation with Antofagasta Plc, overseen by a joint Board of Directors with three Barrick nominees and three Antofagasta nominees. Antofagasta is the operator of the mine.

The mine is located in the Andean Precordillera in Region II of northern Chile, approximately 1,400 kilometers north of Santiago and 175 kilometers southeast of the port city of Antofagasta. An open-pit, heap-leach copper mine, it lies at an average elevation of 3,000 meters. Pure cathode copper is produced by three stages of crushing and stacking, followed by heap leaching and bacterial activity to remove the copper from the ore. Run-of-mine dump leach material is placed on the old sulphide ore pad and leached.

Zaldívar produced 114 million pounds of copper in 2016 (Barrick's share), at a cost of sales of $1.93 per pound, and all-in sustaining costs of $2.05 per pound.1 Barrick's share of proven and probable reserves as of December 31, 2016, was 2.6 billion pounds2 of copper (230 million tonnes, grading 0.51%).

In 2017, Barrick's share of copper production is expected to be 115-125 million pounds, at a cost of sales of $2.10-$2.30 per pound, and all-in sustaining costs of $2.10-$2.30 per pound.1

On December 1, 2015, Barrick completed the sale of 50% of the Zaldívar mine to Antofagasta Plc ("Antofagasta"). Antofagasta is the operator of the joint venture. Accordingly, all information related to Zaldívar on this website, or in any documents accessible from this website, from December 1, 2015 onwards is based on data provided by Antofagasta.

  1. “All-in sustaining costs” per pound is a non-GAAP financial performance measure. “All-in sustaining costs” per pound begins with “C1 cash costs” per pound and adds further costs which reflect the additional costs of operating a mine, primarily sustaining capital expenditures, general & administrative costs and royalties. Barrick believes that the use of “all-in sustaining costs” per pound will assist investors, analysts, and other stakeholders in understanding the costs associated with producing copper, understanding the economics of copper mining, assessing our operating performance, and also our ability to generate free cash flow from current operations and to generate free cash flow on an overall company basis. "All-in sustaining costs" per pound is intended to provide additional information only, does not have any standardized meaning under IFRS, and may not be comparable to similar measures of performance presented by other companies. This measure should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Further details on these non-GAAP measures are provided in the MD&A accompanying Barrick's financial statements filed from time to time on SEDAR at and on EDGAR at
