Pan American Silver Announces Resumption of Operations Previously Suspended by COVID-19 Restrictions

VANCOUVER, June 1, 2020 - Pan American Silver Corp. (NASDAQ: PAAS) (TSX: PAAS) ("Pan American") announced today that operations have resumed at its Dolores and La Colorada mines in Mexico, which follows the restart of its Shahuindo, La Arena, San Vicente and Manantial Espejo operations that was initiated in May. The mines are initially operating at reduced capacities to accommodate new protocols in response to COVID-19. Pan American is currently awaiting the regulatory authorization to resume the Huaron and Morococha operations in Peru. Pan American had suspended normal operations at its mines in Mexico, Peru, Argentina and Bolivia in March 2020 to comply with mandatory national quarantines imposed in response to the COVID-19 pandemic. The Timmins West and Bell Creek mines in Canada have continued to operate at 90% of capacity.

Detailed protocols have been introduced at all mines to protect the health and safety of the workforce. These protocols include strict sanitary measures, return-to-work health screenings and on-site medical personnel to monitor and respond to any health concerns. Pan American is remobilizing the workforce gradually in order to provide greater physical distancing and to allow time to progressively assess and refine the new protocols.

"We are proceeding with a careful approach to restarting operations, as we work towards restoring full production levels at our operations while protecting the health and safety of our people," said Michael Steinmann, President and Chief Executive Officer of Pan American. "The COVID-19 pandemic continues to cause hardship in many of the communities near our operations. We are expanding the humanitarian assistance we have been providing from donations of food and medical supplies to include assistance in sanitation efforts and facilitating access to education."

Pan American withdrew its 2020 operating guidance on March 12, 2020, given the uncertainties related to the COVID-19 pandemic, and plans to update its guidance for 2020 once the impact of the new protocols on operations can be better determined. Pan American also notes that some of the sustaining capital projects planned for 2020 will be carried over into 2021 as a result of COVID-19.
