Illegal Mining at PJV


On August 31, 2015, Barrick completed the sale of 50% of its interest in the Porgera mine to Zijin Mining Group Company ("Zijin"). The Porgera joint venture is operated by Barrick (Niugini) Limited ("BNL"), the joint venture entity, on behalf of Barrick and Zijin. Accordingly, all information related to Porgera on this website, or in any documents accessible from this website, from August 31, 2015 onwards is based on data provided by BNL, the joint venture entity.

  1. 95% basis until August 31, 2015 and a 47.5% basis thereafter.

  2. “All-in sustaining costs” per ounce of gold is a non-GAAP financial performance measure. “All-in sustaining costs” per ounce begins with cost of sales less, among other items, the impact of depreciation, and adds further costs which reflect the additional costs of operating a mine, primarily sustaining capital expenditures, general & administrative costs, and minesite exploration and evaluation costs. Barrick believes that the use of “all-in sustaining costs” per ounce will assist investors, analysts, and other stakeholders in understanding the costs associated with producing gold, understanding the economics of gold 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 ounce is intended to provide additional information only, and does not have any standardized meaning under IFRS. Although a standardized definition of “all-in sustaining costs” was published in 2013 by the World Gold Council (a market development organization for the gold industry comprised of and funded by 18 gold mining companies from around the world, including Barrick), it is not a regulatory organization, and other companies may calculate this measure differently. This measure should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS. Further details on this non-GAAP measure are provided in the MD&A accompanying Barrick’s financial statements filed from time to time on SEDAR at www.sedar.com and on EDGAR at www.sec.gov.
