Gatos Silver, Inc. (NYSE/TSX: GATO) (“Gatos Silver” or the “Company”) today announced the temporary suspension of mine operations as a result of a temporary regulatory suspension of the explosive and blasting permit at the Cerro Los Gatos Mine (“CLG”).

The Mexican Ministry of Defense (“SEDENA”), who regulates all explosives permits in Mexico, temporarily suspended CLG’s explosive and blasting permit on April 21, 2022, following a blasting incident during underground development activities where two blasts were detonated prematurely. There were no physical injuries as a result of the incident, and no significant damage to equipment or infrastructure. Gatos Silver considers the safety of our employees of critical importance, and a thorough investigation of CLG’s blasting procedures is being conducted.

The processing plant has continued to operate normally since April 21, 2022, and will shut down on April 28, 2022 for scheduled maintenance activities. Non-production related activities in the mine are continuing normally. In conjunction with completing the incident investigation this week, the Company expects the reinstatement of CLG’s explosives and blasting permit soon, together with the resumption of normal mine operations and processing activities next week. We do not currently expect any material impact to our current production plans or to our annual production guidance.
