Premier assets production barrick gold mine five cornerstone mines — Cortez and Goldstrike in Nevada, Pueblo Viejo in the Dominican Republic, Lagunas Norte in Peru and Veladero in Argentina — are forecast to contribute 60% of overall in 2015 production at all and in sustaining costs of $725 - $775 per ounce. At two grams per tonne, these mines have an average reserve grade more than double that of peer group average. They are among the most attractive assets in the entire gold industry, generating strong free cash flow even in today’s gold price environment, while offering exceptional leverage to higher gold prices.
Barrick has been successful at consistently finding and replacing reserves and resources through exploration and selective acquisitions. Even during the years of lower gold prices, when most of the industry retrenched, Barrick maintained its commitment to exploration and discovered Lagunas Norte in Peru, one of the few major discoveries of the 1990s. The company's most recent major discovery is Goldrush, located near the Cortez mine in Nevada — the only 10-million-plus ounce green-field discovery by a major gold producer in the past five years.
The 2015 exploration budget of $180 - $220 million1 is allocated to mine site exploration and greenfield projects — primarily on our newest discovery, Alturas, and the El Indio belt.

Exploration Gold Mine In United States
1. Bald Mountain Mine ( Nevada )
The Bald Mountain mine lies within the Southern Ruby Mountains of northeastern Nevada, approximately 110 kilometers northwest of Ely, Nevada and 110 kilometers southeast of Elko, Nevada. Bald Mountain is an open-pit, run-of-mine, heap leach gold mine with conventional heap leaching technology and carbon absorption for ore treatment.
Bald Mountain produced 161,000 ounces of gold in 2014 at all-in sustaining costs of $1,070 per ounce.
Proven and probable mineral reserves as at December 31, 2014, were 1.36 million ounces of gold
2. Cortez mine ( Nevada )
The Cortez mine is located 100 kilometers southwest of Elko, Nevada in Lander County. The Cortez Pipeline property is 11 kilometers northwest and the Cortez Pediment property (which includes the Cortez Hills deposit) is four kilometers southeast of the original Cortez milling complex. The Pipeline and South Pipeline deposits are mined by conventional open-pit methods. The Cortez property covers approximately 2,800 square kilometers on one of the world’s most highly prospective mineral trends.
Cortez employs three different metallurgical processes to recover gold. Lower-grade oxide ore is heap leached, while higher-grade non-refractory ore is treated in a conventional mill using cyanidation and a carbon-in-leach (“CIL”) process. Heap leached ore is hauled directly to leach pads for gold recovery. Carbonaceous mill ore is mined intermittently during the mining of the Pipeline/South Pipeline deposits. A prefeasibility study for underground mining at Cortez below currently permitted levels will be completed in late 2015.
Mineralization in this zone is primarily oxide and higher grade compared to the current underground mine, which is sulfide in nature. The limits of the Lower Zone have not yet been defined, and drilling has indicated the potential for new targets at depth. The exploration drift has been extended to the south, enabling additional step-out drilling, which is anticipated to begin in June. Drill results to date include 36.6 meters at 31.5 grams per tonne and 27.4 meters at 20.9 grams per tonne, both oxide in nature, which compare favorably with the average grade of 13.8 grams per tonne in refractory ore above the 3,800 foot level

1. Pascua Lama Mine ( Frontera )
The Pascua Lama project is located on the border of Chile and Argentina, in the Frontera district at an elevation of 3,800 to 5,200 meters, approximately 10 kilometers from Barrick’s Veladero mine. It has 15.4 million ounces of gold reserves and more than 674 million ounces of contained silver. During 2013, Barrick announced the temporary suspension of construction at Pascua-Lama, except for activities required for environmental and regulatory compliance. The ramp-down process has been completed on schedule and budget and the project is now on care and maintenance.
Pascua-Lama's new Executive Project Director, Sergio Fuentes, reports to our Co-Presidents and comes to Barrick after nearly three decades of successfully managing the construction of complex mining projects in Chile, including high-altitude operations in the Andes. He and the team he is assembling are working hard to assess Pascua-Lama's economics going forward. To do so, they will address the project's outstanding legal and regulatory hurdles, and will complete a new execution plan to optimize remaining construction activities. If that plan aligns with our capital allocation objectives and demonstrates an acceptable return on invested capital of at least 15%, we will consider resuming development of Pascua-Lama. In any scenario, the company must permit and construct a new water management system in Chile.
We will submit our application for the new system by mid-year, with permitting expected to take two years. In the meantime, we are working to minimize the costs of holding the asset. In 2015, Barrick anticipates expenditures of approximately $170 - $190 million for the project, including approximately $140 - $150 million for care and maintenance, including water management system costs, and approximately $30 - $40 million1 for other project costs, including those related to permit obligations in Argentina and Chile.
