1. Mineral reserves (“reserves”) and mineral resources (“resources”) have been calculated as at December 31, 2012 in accordance with National Instrument 43‐101 as required by Canadian securities regulatory authorities. For United States reporting purposes, Industry Guide 7, (under the Securities and Exchange Act of 1934), as interpreted by Staff of the SEC, applies different standards in order to classify mineralization as a reserve. Accordingly, for U.S. reporting purposes, approximately 1.98 million ounces of reserves at Pueblo Viejo (Barrick’s 60% interest) is classified as mineralized material. In addition, while the terms “measured”, “indicated” and “inferred” mineral resources are required pursuant to National Instrument 43‐101, the U.S. Securities and Exchange Commission does not recognize such terms. Canadian standards differ significantly from the requirements of the U.S. Securities and Exchange Commission, and mineral resource information contained herein is not comparable to similar information regarding mineral reserves disclosed in accordance with the requirements of the U.S. Securities and Exchange Commission. U.S. investors should understand that “inferred” mineral resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. In addition, U.S. investors are cautioned not to assume that any part or all of Barrick's mineral resources constitute or will be converted into reserves. Calculations have been prepared by employees of Barrick, its joint venture partners or its joint venture operating companies, as applicable, under the supervision of Rick Sims, Senior Director, Resources and Reserves, of Barrick, David Londono, Director, Open Pit Life‐of‐Mine Business Planning, of Barrick and Steven Haggarty, Senior Director, Metallurgy, of Barrick. Except as noted below, reserves have been calculated using an assumed long‐term average gold price of $US 1,500 per ounce, a silver price of $US 28.00 per ounce, a copper price of $US 3.00 per pound and exchange rates of 1.0 $Can/$US and 1.00 $US/$Aus. Reserves at Round Mountain have been calculated using an assumed long‐term average gold price of $US 1,200. Reserve calculations incorporate current and/or expected mine plans and cost levels at each property. Varying cut‐off grades have been used depending on the mine and type of ore contained in the reserves. Barrick’s normal data verification procedures have been employed in connection with the calculations. Resources as at December 31, 2012 have been estimated using varying cut‐off grades, depending on both the type of mine or project, its maturity and ore types at each property. For a breakdown of reserves and resources by category and for a more detailed description of the key assumptions, parameters and methods used in calculating Barrick’s reserves and resources, see Barrick’s most recent Annual Information Form/Form 40‐F on file with Canadian provincial securities regulatory authorities and the U.S. Securities and Exchange Commission. 2. In connection with the write‐down of the Company’s investment in Tethyan Copper Company (TCC), which holds the Company’s interest in the Reko Diq project, the Company has removed the estimate of mineralized material associated with the Reko Diq project from its statement of resources for 2012. For additional information regarding this matter, see pages 20 and 139 of Barrick’s Year‐End Report 2012. 147
