Construction is expected to commence immediately with completion expected late 2020 subject to finalizing detailed engineering and securing remaining permits, in line with the project timetable.

At full capacity, Juanicipio is expected to produce on average 11.7 moz of silver and 43.5 koz of gold per year, with robust economics underpinning the project.

Octavio Alvídrez, Chief Executive Officer of Fresnillo Plc, said:

“The decision to approve Juanicipio reflects the extensive work the JV partners have done to de-risk the project to meet stringent development criteria. This decision to invest demonstrates our confidence in the long-term outlook for mining in Mexico.
