San Rafael Mine is currently at full production and mill throughput. As the sole source of mill feed at the Cosalá Operations, it is a low-cost silver-zinc-lead underground mine located approximately 9 km from the Los Bracero’s mill. The mine is expected to double current silver production and exceed 1 million ounces by 2021, driven by production growth from the Main, Central and Upper zones. Development of the Main Zone was completed in Q4 2018, mining of the central Main Zone commenced earlier this year, and mining of the high-grade silver in the Upper Zone is expected to begin by 2020.
