Geology of the Gold Deposits of the Yanacocha District, Northern Peru

摘要

The Yanacocha District is located 20 km north of the city of Cajamarca, in the Northern Andean Orogenic belt of northern Peru. Gold production may have occurred as early as Incan times (Paverd, 2000),.but modern exploration that began in the 1960s targeted only copper and silver. Newmont Mining Corporation, BRGM and Compania de Minas Buenaventura began exploring for gold in 1983, with Newmont as operator. Initial drilling took place in 1985. By 1992 a reserve of 1.28 million ounces was reported (Teal et al, 2002). Production began at the Carachugo deposit in 1993. Current reserves are 31.7 million ounces at
