Peñasquito Mine

The primary ore for the Peñasquito Polymetallic Mine is in two diatreme breccias, named the Peñasco and the Brecha Azul.

The rock surrounding the diatremes contain disseminated galena, sphalerite and sulfosalts within phyllic (sericite–pyrite–quartz) and proplytic (chlorite–epidote–pyrite) hydrothermal alteration envelopes.

Where the diatremes intersect limestone units manto deposits of ore mineralization occur.

In 2019, Newmont acquired Goldcorp, obtaining full ownership interest in Peñasquito, which consists of the Peñasco and Chile Colorado open pit mines.

Goldcorp had been forced to "announce a temporary suspension of operations due to a blockade by truck drivers protesting a loss of contracts at the country’s biggest gold deposit.
