Peñasquito is an open-pit mine composed of two main deposits, Peñasco and Chile Colorado, which host gold, silver, lead and zinc reserves. Peñasquito is operated by Minera Peñasquito S.A. de C.V., a subsidiary of Newmont Corporation (“Newmont”), and is situated in the western half of the Concepción Del Oro district in the northeast corner of Zacatecas State, Mexico.

Open-pit mining commenced in 2010 and full production was achieved in 2011. Open-pit mining is undertaken using a conventional truck-and-shovel fleet. Processing of sulfide ore to produce zinc and lead concentrates uses a conventional crushing, milling and flotation facility with a design capacity of 130,000 tonnes per day (tpd).
