Gatos Silver Reports Record Production Performance During Fourth Quarter 2021

Gatos Silver, Inc. (NYSE/TSX: GATO) (“Gatos Silver” or the “Company”) is very pleased to report record silver production and plant throughput from the 70%-owned Cerro Los Gatos (“CLG”) mine during the fourth quarter of 2021 (”Q4”).

2021 and Q4 Operating Performance

Silver production in Q4 was 2.3 million ounces and increased 35% compared to the third quarter 2021 (“Q3”), due primarily to higher mined silver ore grades as well as higher throughput and recoveries. Lead and zinc production in Q4 were slightly below Q3 levels, due to lower mined lead and zinc ore grades. CLG’s 2021 silver production of 7.6 million ounces exceeded the Company’s guidance of 7.4 million ounces. Zinc and lead production of 50 million and 40 million pounds, respectively, were both consistent with the Company’s 2021 guidance range.

CLG achieved record throughput in Q4 totaling 241,397 tonnes, exceeding Q3 throughput by 3.1%. For 2021, 909,586 tonnes were processed, a 36% increase compared to 2020, which included a 45-day pandemic-related temporary suspension of plant operations.

CLG achieved record silver recovery during Q4, with recoveries for silver, lead and zinc continuing to exceed design rates.

Due to record 2021 production, and elimination of debt service requirements by the early retirement of the Los Gatos Joint Venture (“LGJV”) Working Capital Facility and Term Loan during 2021, the LGJV had over $20 million of cash at December 31, 2021.

CLG comparative production highlights are summarized below:

Stephen Orr, Chief Executive Officer, stated, “CLG’s record performance in Q4 reflects the progressive enhancements to processing and mining productivity throughout 2021. Improvement initiatives included continual refinements to the mining cycle which allowed the mine to increase daily production to more than 2,600 tonnes per day by year-end. Additional infrastructure additions completed during 2021, such as the Central Zone refrigeration plant and improved water management facilities, will help ensure these production improvements are sustainable and facilitate access to higher grade ore zones. Commissioning of real-time monitoring and reagent addition in the process plant’s flotation circuits improved recoveries for silver, zinc, lead and gold. All these improvements had a compounding effect that contributed to the outstanding Q4 performance. The CLG operation is now positioned for further production improvement initiatives and cost reduction in 2022.”
