Peñasquito

Peñasquito is a large polymetallic open-pit mine in the Mazapil municipality of Zacatecas, Mexico, producing gold, silver, lead and zinc and wholly owned by Newmont. Development ran from early-2000s exploration through construction beginning in 2007 to commercial startup in March 2010, passing through Glamis Gold and Goldcorp before Newmont's 2019 acquisition. Holding one of the largest silver resources on the planet, it ranks among Mexico's biggest precious-metals operations and is counted among the world's top handful of silver producers.
