Development of the mine “is not contingent” on the April 10 presidential election results in Peru, Garofalo said. Opposition candidate Ollanta Humala, who has pledged to renegotiate contracts with foreign mining companies if elected, won the first round of voting on April 10 and faces a June runoff against first-term Congresswoman Keiko Fujimori.
“We’re confident that democratic institutions will enable the country to ride out any candidate,” Garofalo said. “The balance of Congress reflects the maturity of democracy in Peru.”
