Gatos Silver Reports Record Tonnage and Metal Production During Second Quarter 2021

Gatos Silver, Inc. (NYSE/TSX: GATO) (“Gatos Silver” or the “Company”) is pleased to report record production from the 70%-owned Cerro Los Gatos mine (“CLG”) during the second quarter of 2021 (”Q2”).

CLG Q2 Operating Performance

Gatos Silver achieved strong operating performance in Q2 at the CLG mine which produced a quarterly record of 240,047 ore tonnes. The plant achieved record throughput processing 230,656 tonnes, exceeding the first quarter 2021 (“Q1”) performance by 13%.

CLG production highlights are summarized below:

Stephen Orr, Chief Executive Officer, stated “CLG’s impressive Q2 mine and plant performance produced record results. Mine development during Q2 accessed the expected higher-grade ore forecast to be mined during 2021 and the plant production averaged a record 2,535 tonnes per day, above the design capacity of 2,500 tonnes per day. Record recoveries for silver, lead and zinc achieved in the quarter were also well above design. The higher tonnage and ore grades combined with the plant’s higher throughput and metals recoveries yielded record metals production. As demonstrated by our excellent Q2 performance, we are progressing well against our 2021 production guidance.”
