In 1994, Barrick acquired the Pascua Lama project as an exploration property through the Lac Minerals acquisition. A description of the project is found in Wells et al. (2001). The Pascua Lama project is located at the northern end of the El Indio Belt in Chile’s Region III and Argentina’s San Juan province straddling the Chile-Argentina border. The process plant is located in Argentina. It is approximately 150 km (90 miles) southeast of Vallenar, Chile, 500 km (300 miles) northeast of Santiago, Chile and 280 km (175 miles) northwest of San Juan, Argentina. The site is at an elevation that ranges from approximately 4,000 to 4,800 m (13,000 to 15,750 ft) above sea level.
