|Location:||Zacatecas, Fresnillo District|
|Facilities:||Leaching plant (Saucito mine), flotation plants (Saucito, Fresnillo mines)|

|Anticipated Production:||Annual average 3.5 moz silver and 13.0 koz gold|
|Capex:||US$ 155 million|
The Pyrites plant is expected to improve overall recoveries of gold and silver, and therefore maximise production in the Fresnillo district; expected to total an average of 3.5 moz silver and 13 koz gold per year once both phases are operating at full capacity.
This project was divided into two phases, the first phase consisted of the iron flotation circuit and pyrites leaching plant at the Saucito mine, which was commissioned mid-2018. The second phase, a 14,000 tpd tailings flotation plant at the Fresnillo mine, is under construction and is expected to be concluded in 2H20.
The second phase, a flotation circuit, will treat the ongoing and historical tailings from the Fresnillo mine to produce a pyrites concentrate which will be sent to a filtration plant and then on to the leaching plant at Saucito, the final part of the process to produce the precipitates. Commissioning of phase II of the Pyrites plant set for 2H 2020.
