Sierra Metals Announces Extension to the Suspension of Its Yauricocha Mining Operations Until April 26, 2020

Igor Gonzales, President and CEO of Sierra Metals, commented, "Our team continues to be focused on the health and safety of our workforce, and as such, we will continue only to maintain a smaller workforce to oversee the critical aspects of operations. The primary goal of this essential crew is to facilitate a quick and efficient ramp-up back to normal levels once the state of emergency is lifted. Processes relating to any permitting applications continue to be deferred during the state of emergency."

The Company continues to be prepared to recommence and ramp up production very quickly. It has the operating flexibility to run the ore processing mill above the 3,150 tonnes per day capacity, which should help Yauricocha recover lost ore tonnages from the work stoppage.

Due to the rapidly changing developments of the COVID-19 Pandemic and the effect they could have on the Company's operations and financial condition, the Company continues to implement proactive and reactive mitigation measures to minimize potential impacts on our workforce, communities, operations and supply chain. These measures also include preserving capital and deferring capital expenditures where appropriate, to improve liquidity. Guidance remains suspended, as we evaluate our mines. The Company expects to provide a more comprehensive update with more data points on metal prices and operating developments as part of the Q1 2020 reporting process.
