The project represents 5.2 million and 1.4 million ounces of gold in reserves and non-reserve mineralization (NRM) attributable to Buenaventura, respectively, as well as 1.4 billion and 0.4 billion pounds of copper in reserves and NRM attributable to the company, respectively.

According to the company, the project has the potential to add gold and copper reserves with further exploration.

Initial production at the project is expected to begin in late 2014 to early 2015, with an approximate six-month ramp-up period to achieve commercial production for the first five years of 580,000 to 680,000 ounces of gold and 155 to 235 million pounds of copper.

The expected life of mine for the Conga project is approximately 19 years, Buenaventura said.
