Conversion of Pueblo Viejo Power Plant to Natural Gas

Press Release

Barrick Announces Conversion of Pueblo Viejo Power Plant to Natural Gas

Conversion Reduces Costs, Supports Expansion Project, and Lowers Greenhouse Gas Emissions Over Life of Mine

TORONTO — Barrick Gold Corporation (NYSE:ABX)(TSX:ABX) (Barrick or the “Company”) today announced that Pueblo Viejo Dominicana Corporation (“PVDC”), operator of the Pueblo Viejo mine, has signed a 10-year natural gas supply contract with AES Andres DR, S.A. in the Dominican Republic that will enable the conversion of the Quisqueya I power generation facility from heavy fuel oil to natural gas. PVDC is a joint venture between Barrick (60 percent) and Goldcorp Inc. (40 percent).

Quisqueya I is owned and operated by PVDC and supplies power to the Pueblo Viejo mine. Converting the facility from heavy fuel oil to natural gas is expected to reduce the mine’s average cost of sales1 and all-in sustaining costs2 by approximately $54 per ounce over the life of the mine3, supported in part by higher margins on the sale of excess power to the national energy grid. Cost savings expected from the conversion of the facility from heavy fuel oil to natural gas are reflected in the Company’s most recent consolidated cost guidance for 2019 to 2022.

“Pueblo Viejo is already a core asset with industry-leading margins and a strong track record of operational excellence,” said Greg Walker, Senior Vice President, Operational and Technical Excellence. “Converting the mine’s power plant to natural gas is expected to reduce Pueblo Viejo’s cost structure and drive incremental improvements in cash flow over the life of the mine, driving additional long-term value for our owners, as well as our government and community partners.”

In addition, the use of natural gas is expected to reduce greenhouse gas emissions associated with Pueblo Viejo by approximately 260,000 CO2 equivalent tonnes per year.

PVDC will invest roughly $7.5 million to convert Quisqueya I to natural gas, an investment that significantly exceeds Barrick’s 15 percent hurdle rate. AES will construct a new gas pipeline to the facility, with commercial gas production expected to begin in the second half of 2019.

Barrick is currently advancing prefeasibility-level studies for a plant expansion at the Pueblo Viejo mine that has the potential to significantly increase throughput at the operation4. Conversion of the power plant to natural gas is anticipated to further strengthen the economics of the project.

PVDC was advised by the Houston office of Akin Gump Strauss Hauer & Feld LLP.

The scientific and technical information contained in this press release has been reviewed and approved by Geoffrey Locke, P. Eng., Manager, Metallurgy of Barrick, who is a “Qualified Person” as defined in National Instrument 43-101 – Standards of Disclosure for Mineral Projects.

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

“All-in sustaining costs” per ounce is a non-GAAP financial performance measure. “All-in sustaining costs” per ounce begins with “cash costs” per ounce and adds 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 “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 25 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 is provided in the MD&A accompanying Barrick’s financial statements filed from time to time on SEDAR at and on EDGAR at

Compared to the continued use of heavy fuel oil and based on an oil price assumption of $70 per barrel and a natural gas price assumption of $3.75/MMbtu.
