The Golden Sunlight mine is located in Jefferson County in southwestern Montana, 55 kilometers east of Butte and eight kilometers northeast of Whitehall. The property lies on the eastern flank of a fault-bounded mountain range known as Bull Mountain.

Golden Sunlight is mined by conventional open-pit methods. The ore treatment plant uses conventional carbon-in-pulp technology as well as Sand Tailing Retreatment (STR), designed to recover gold that would otherwise be lost in the process.

Golden Sunlight produced 34,000 ounces of gold in 2016, at a cost of sales of $1,512 per ounce, and all-in sustaining costs of $1,493 per ounce.1 Proven and probable mineral reserves as of December 31, 2016, were 71,000 ounces of gold 2 (827,000 tonnes, grading 2.67 grams per tonne).

In 2017, gold production is expected to be 35,000-50,000 ounces, at a cost of sales of $1,200-$1,550 per ounce, and all-in sustaining costs of $1,200-$1,300 per ounce.1

  1. “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 and on EDGAR at
