The Yanacocha gold mine did not exist when Reinhard Seifert first moved to Cajamarca, Peru in the 1970s. Everything changed in 1993, when Denver-based Newmont Mining Corp. opened Yanacocha and spurred a modern gold rush of sorts. In 2011, the company proposed expanding its operations with a megaproject known as the Conga mine, a project instantly met with relentless, sometimes violent, anti-mining demonstrations. Four years later, the Conga mine expansion remains on hold under environmental review. Throughout this period, Seifert played a pivotal role in the anti-mining movement as former president of the Environmental Defense Front of Cajamarca.
