Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (NYSE AMERICAN: SMTS) (“ SierraMetals ” or the “ Company ”) reports that the Peruvian and Mexican Federal Governments have extended their suspensions of all non-essential activities to contain the advancement of COVID-19 virus. In Peru, the suspension will now continue until May 10, 2020, and in Mexico, the suspension will now continue until May 30, 2020. Also, the Mexican Government has announced that suspension of activities will not apply to the municipalities that present a low or null transmission of COVID-19 as of May 18, 2020. The Mexican Government is expected to set clear guidelines before that time.

These extensions affect the Company’s mining activities in both countries. However, there is a possibility that the Bolivar Mine in Mexico may be able to resume operations on May 18, 2020, based on its remote location. Currently, the Company maintains essential operation and service crews, at both the Yauricocha and Bolivar Mine sites. The Cusi Mine remains in care and maintenance due to its proximity to urban communities.

Igor Gonzales, President and CEO of Sierra Metals commented, “Our team continues to focus on the health, safety, and wellbeing of our workforce. We have retained smaller workforces at both Yauricocha and Bolivar to oversee the critical aspects of our operations, with plans to restart Yauricocha on May 11 th, and Bolivar potentially on May 18 th. Our primary goal is to facilitate a ramp-up back to normal levels as quickly and efficiently as possible once the suspensions are lifted. Our Cusi employees remain at home during this time, and the Mine remains in care and maintenance.”

He continued, “it is worth noting that we do have flexibility at Yauricocha to run operations at higher throughput levels, which will help us to recover some of the lost production. Also, at Bolivar, we have some potential to increase throughput, to possibly help us recover some of the lost production there as well.”

Due to the continued impact of the COVID-19 related work interuptions at all the Company’s mines, the 2020 production and cost guidance remains suspended until a complete review of operations is completed. The Company continues to evaluate all mines and expects to provide a more comprehensive update as part of the Q1 2020 reporting process.
