Commercial production was achieved at the Pinos Altos mine in November 2009 and, under current mine plans, the mine is expected to be in production through 2027. A shaft sinking project was completed in June 2016 at the Pinos Altos mine and during 2018, the site transitioned into being a predominantly underground mining operation.
In 2020, the Agnico Eagle started underground and open pit production at Sinter, located approximately 2 kilometres northwest of the Pinos Altos minesite and depleted the Bravo pit at Creston Mascota in the third quarter of 2020, with residual gold leaching continuing through 2023.
Initial production at the Cubiro satellite deposit is expected in the second half of 2024. Once production commences, Cubiro is expected to provide additional production flexibility to the Pinos Altos operations.
At Reyna de Plata, open pit pre-stripping activities at Pit 1 were completed in the fourth quarter of 2022 and ore production commenced as planned.
Production from the San Eligio zone continued to ramp up in the fourth quarter of 2023, with seven stopes mined in the quarter, and provides increased production flexibility to the Pinos Altos mine.
The underground mining method is sublevel stoping (paste backfill) to extract ore from the Santo Niño, Cerro Colorado and Oberon de Weber deposits.
Ore is transported to the surface by shaft hoisting as well as by trucks via a ramp system.
