Gatos Silver Reports Second Quarter 2022 Production Results

Gatos Silver Inc. (NYSE/TSX: GATO) ("Gatos Silver" or the "Company") today announced production results from the 70%-owned Cerro Los Gatos ("CLG") mine for the quarter and six months ended June 30, 2022.

Production Results

CLG continues to deliver strong operational results. During the second quarter of 2022, silver production increased by 9% and lead and zinc production increased by 5% and 8%, respectively, compared to the second quarter of 2021. The increased production was primarily due to significantly higher mined ore grades, in addition to improved recoveries. Silver production increased 29% in H1 2022, compared to H1 2021. Lead and zinc production increased 16% and 26% respectively during the same period. The increase in production in H1 2022 is as a result of higher mill throughput, increased grades and higher recoveries compared to H1 2021.

CLG achieved record feed grades and record recoveries for silver, lead and zinc during the quarter. Mill throughput was 211,350 tonnes, a decrease of 8% compared to the second quarter of 2021, as a result of a temporary blasting suspension in the mine for over two weeks starting in late April. Milling operations were suspended for 11 operating days due to the blasting suspension. Excluding the suspension time, the mill averaged 2,642 tonnes per day during the quarter and averaged 2,710 tonnes per day in June supported by continued optimization efforts in the mine.

Despite the temporary mining suspension, CLG achieved record lead and zinc production during the quarter. The Company believes that CLG remains on target to achieve its annual production guidance for 2022, including the plans to achieve plant throughput levels of 2,700 tpd for the second half of 2022.

CLG comparative production highlights are summarized below:

*Recoveries are reported for payable metals in the identified concentrate. Recoveries reported previously in 2021 were based on total metal in both concentrates.

Corporate Update

The Company continued to strengthen its executive management team during the second quarter with the previously announced appointment of a new CFO, a VP Finance and a VP Corporate Development and Business Improvement, in addition to various senior appointments at CLG including a new General Manager of Operations.

The Los Gatos Joint Venture ("LGJV") paid its first dividend of $20 million to its partners in April 2022, and the Company expects to receive another dividend in the third quarter of 2022 given the continued strong operating performance of CLG. The LGJV had a cash balance of $40 million as of June 30, 2022.

The Company continues to advance efforts to produce an updated life-of-mine plan and update its mineral resources and mineral reserves. This update will incorporate information since the CLG mine commenced operation and will account for production mined through to June 30, 2022. The resource and reserve is being completely rebuilt from base data, including data compilation of surface drilling, underground drilling, underground mapping and production data, comprehensive data validation, structural and geological interpretation, resource estimation, reconciliation to actual production, and a new mine design including updates to operating and capital costs. As previously disclosed, the Company expects to produce a new CLG life-of-mine plan and technical report during the second half of 2022.

The Company is also evaluating the material weaknesses in its internal controls over financial reporting related to the mineral reserve reporting errors. The Company's financial statements for the year ended December 31, 2021 and quarter ended March 31, 2022 may be affected by the ongoing analysis.
