Pueblo Viejo is an open-pit gold mine owned by a joint venture in which Barrick Gold Corporation (Barrick) holds a 60% operating interest and Newmont Corporation holds the remaining 40% interest. The mine is located in the central part of the Dominican Republic in the province of Sanchez Ramirez.

The Pueblo Viejo mineralization is predominantly pyrite, with lesser amounts of sphalerite and enargite. Pyrite mineralization occurs as disseminations, layers, replacements, and veins. Sphalerite and enargite mineralization is primarily in veins, but disseminated sphalerite has been noted in core.

Pueblo Viejo achieved commercial production in January 2013 and completed its ramp-up to full design capacity in 2014. Pueblo Viejo consists of two open-pits, Moore and Monte Negro, and is mined by conventional truck-and-shovel methods. The Pueblo Viejo ore is refractory and consists primarily of gold and silver intimately associated with pyrite that occurs as encapsulated sub-micron particles and in solid solution. Processing of whole ore is completed by pressure oxidation followed by carbon-in-leach (CIL) cyanidation of the autoclave product. The processing plant design capacity is 24,000 tonnes per day.

Barrick is currently advancing a plant expansion and mine life extension project designed to increase throughput to 14 million tonnes per annum, allowing the operation to maintain minimum average annual gold production of approximately 800,000 ounces after 2022 (100% basis). The expansion of Pueblo Viejo will extend its life to 2040 and beyond.
