Mexico environmental agency defends oversight of Goldcorp mine

Mexico's environmental prosecutor said it had kept regular oversight of the country's largest gold mine, days after a Reuters report on a prolonged leak of contaminated water there prompted activists to accuse the agency of failing its mandate.

Environmental prosecutor Profepa said that since 2013 it had completed five "administrative proceedings" on the Penasquito mine in Zacatecas state, which is owned by Canada's Goldcorp Inc.

It did not say whether the proceedings were related to the leak.
