Newmont Mining Corp: Human Rights/Environmental Violations, Cajamarca, Peru

Newmont Mining Corp. is the principle shareholder of Minera Yanacocha S.R.L, a joint venture between Newmont (51.35%), the Peruvian Buenaventura (43.65%) company, and the World Bank’s International Finance Corporation (5%).[1] Minera Yanacocha owns the Yanacocha mine located in Cajamarca, Peru. Spread across 600 sq. miles, it is the second largest and most profitable gold mine in the world.[2] The Yanacocha open pit mine has generated several controversies since its launch in 1993, particularly for causing severe damage to local water resources.[3]

The familiar view of mining as a driver for local economic development proved false in Cajamarca: after hosting 20 years of mining activities, the region is still one of the poorest in the country.[4] While companies claim to create employment opportunities, many residents in the area have lost their livelihoods.[5] Frequent water shortages, environmental destruction, and the disappearance of arable land in the region all indicate that mining is irreconcilable with the dominant activities in the local economy (i.e. agriculture and tourism).[6]

Minera Yanacocha began construction of the Minas Conga project in 2010. Minas Conga is located at the convergence of five major river basins in the area. Pollution from the mine puts the region’s waterways, livelihoods, and water rights at risk.[7] The Minas Conga Project threatens to destroy four lakes, affect 680 springs, and consume at least 228,000 liters of water per hour in a region already prone to water shortages.[8] The project threatens to drastically alter Cajamarca’s surface water drainage system and would affect multiple water sources, intensifying the community’s existing environmental woes. Furthermore, the Conga project has failed to implement acceptable CSR protocols and continues to operate without consent from the local population. Upon review, the Conga project’s 9,000 page Environmental Impact Assessment (EIA) was described as “disorganized” and “inadequate” given the scale of investment. Conga’s EIA only recognizes 32 communities in the mine’s range of influence.[9]

According to ILO Convention No. 169, ratified by the Peruvian government, potentially affected communities had the right to be consulted regarding the Minas Conga Project – something the Peruvian government failed to do. Protests intensified in 2011 resulting in violent suppressions by Peruvian police forces and countless human rights violations. In response to the protests, the Peruvian government declared a state of emergency, placing Cajamarca under a heavy military presence for three months.[10] The Peruvian government ordered the project’s suspension shortly thereafter, in November 2011. [11]

A formal complaint was filed with the InterAmerican Commission on Human Rights (IACHR) in April 2012.[12] A survey by IPSOS APOYO published in August 2012 reported that 78% of the population in Cajamarca is against the Conga Project, with only 15% in favor of it.[13]  In July 2012, the Peruvian National Police suppressed a demonstration wounding many and killing five.[14] Locals claim that police arbitrarily detain or arrest peaceful demonstrators and that the mine actively targets social leaders who speak out.

Still, the company and the Peruvian government continue to move forward with the project. On June 22, 2012, Newmont announced its decision to take a “water first” approach, building reservoirs on high-mountain lake areas before building production facilities or commencing mining activities to ensure water supplies for the locals. Construction of the first such reservoir was completed in May, 2013. Newmont claims that these reservoirs will provide year-round water supplies in areas that currently suffer during the dry season. Construction of an access road and other infrastructure related to the project are going on simultaneously. [15]
