Cost of sales
per ounce ? Cost of sales applicable to gold per ounce is calculated using cost of sales applicable to gold on an attributable basis (removing the non-controlling interest of 40% Pueblo Viejo and 36.1% Acacia from cost of sales), divided by attributable gold ounces.

All-in sustaining
costs per ounce ? “Cash costs” per ounce and “All-in sustaining costs” per ounce are non-GAAP financial performance measures. “Cash costs” per ounce starts with cost of sales applicable to gold production, but excludes the impact of depreciation, the non-controlling interest of cost of sales, and includes by-product credits. “All-in sustaining costs” per ounce begin with “Cash costs” per ounce and add further costs which reflect the additional costs of operating a mine, primarily sustaining capital expenditures, general & administrative costs, minesite exploration and evaluation costs, and reclamation cost accretion and amortization. Barrick believes that the use of “cash costs” per ounce and “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. “Cash costs” per ounce and “All-in sustaining costs” per ounce are intended to provide additional information only and do 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 23 gold mining companies from around the world, including Barrick), it is not a regulatory organization, and other companies may calculate this measure differently. These measures should not be considered in isolation or as a substitute for measures 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 www.sedar.com and on EDGAR at www.sec.gov.
