Yanacocha Mine, Peru

The expanding Yanacocha Mine dominates the land change seen in this series of images. Operated by the Newmont Mining Corporation in Greenwood Village, Colorado, the Yanacocha Mine is the second largest gold mine in the world, and the largest in Latin America. Consisting of seven distinct deposits, the open pits cover over 30,000 hectares of land.

The mine is located about 45 kilometers from Cajamarca in northern Peru on top of Yanacocha Mountain at an altitude of 4,700 meters, nestled in the Andes Mountains.

Mining operations at Yanacocha have been continuously expanding since 1993. Production peaked in 2005 when the mine produced 3.33 million ounces of gold. In 2014, just over 1 million ounces of gold came out of the mine. As of December 31, 2014, reserves are estimated to be 155 metric tons of gold.

In these false-color Landsat images, the expansion of the open pit mining is shown in varying shades of pink. Green is vegetation, and agricultural areas near the city of Cajamarca (visible as bright pink and purple shades) appear as bright green in the bottom center of the images.
