Net loss for the fourth quarter of 2020 was $8.8 million compared to $13.3 million in the fourth quarter of 2019. The lower loss was primarily due to the substantial improvement in the profitability of the LGJV, partially offset by higher public company costs related to increased G&A compensation, insurance, consulting expenses and interest expense. Net loss for the year ended 2020 increased $4.1 million to $35 million compared to 2019 primarily due to the higher equity loss in the LGJV, higher G&A compensation, insurance and consulting costs, arrangement fees and interest expense.

Stephen Orr, the Company's Chief Executive Officer, stated: "This past year was transformative for Gatos Silver. The Company completed the largest precious metals IPO in 2020 on the NYSE and TSX. Despite the pandemic related 45-day temporary suspension of mining activities imposed by Mexico, design throughput was achieved at the CLG mine in late 2020 and the LGJV achieved profitability during the last two quarters of the year."

Los Gatos Joint Venture

The LGJV successfully controlled COVID-19 infection at the CLG project and the surrounding local communities through proactive COVID-19 prevention programs, including seminars and donation of personal protection items such as face masks, hand sanitizer and nitrile gloves. All employees and contractors are nasal tested for COVID-19 prior to entry to the CLG site.

Revenue increased for the fourth quarter 2020 compared to the same quarter of 2019 due to increased metals prices and higher production rates. Revenue in the fourth quarter 2020 was $40.3 million. Lead and zinc concentrate production for the fourth quarter was 6,425 tonnes and 7,823 tonnes, respectively. The Company generated $121.5 million in revenue during 2020, representing a 223% increase from 2019 due to higher metal prices and production rates in 2020. The CLG mine commenced production in September 2019 and completed its project commissioning phase in late December 2020 achieving the designed 2,500 tpd throughput rate. Lead and zinc concentrate production for the year ended December 31, 2020 was 21,254 tonnes and 27,728 tonnes, respectively.

Operating expenses decreased to $35.5 million for the quarter ended December 31, 2020 compared to the fourth quarter of 2019 primarily due to lower cost of sales. During the initial start-up period in 2019, higher costs were incurred for labor, pumping and supplies. Operating expenses for the year ended December 31, 2020 increased $77.2 million to $126 million primarily due to the higher 2020 production.

Other expenses decreased to $1.9 million for the fourth quarter 2020 compared to the fourth quarter of 2019 due to reduction in interest expense and arrangement fees and an increase in foreign exchange gain. Other expenses increased to $23.2 million for the year ended December 31, 2020 primarily due to a full year of interest and arrangement fee expenses. Upon commencing production, interest cost and arrangement fees are charged to operations. Interest cost and arrangement fees were capitalized as part of the cost of construction prior to the September 1, 2019.

Capital Resources Update

With the completion of a $150 million gross proceeds IPO on October 30, 2020, and subsequent exercise of the related underwriters' option for gross proceeds of $22.5 million in early November 2020, the Company has sufficient funds and resources to carry out its business plans. At December 31, 2020, cash and cash equivalents were $150.1 million. Gatos Silver did not have any debt at December 31, 2020 or 2019.

On March 11, 2021, Gatos Silver repurchased from its joint venture partner, Dowa Metals & Mining Co., Ltd., ("Dowa") an approximate 18.5% interest in the LGJV for $71.6 million, increasing the Company's ownership to 70.0% and extinguished the $60 million LGJV Working Capital Facility of which Gatos Silver's attributable portion was $42 million.

2021 - A Year of Optimization

Numerous strategic capital initiatives designed to enhance production efficiency and to maintain best-in-class standards are planned for 2021. As a result, sustaining capital expenditures are expected to range between $65 and $75 million. Infrastructure, such as a paste backfill plant and mine refrigeration plant, will be integrated to reduce operating costs and increase productivity. Additional generator capacity will be added to supplement the current backup power system when weather events cause outages on Mexico's national electrical grid.

In 2021, the CLG recovered metal production is expected to start approaching life-of mine averages resulting in 7.5 - 7.9 million ounces of silver, 40 - 42 million pounds of lead and 49 - 52 million pounds of zinc at an All-In Sustaining Cost of $17 - $17.5/Ag oz.

Mr. Orr added: "As we communicated in the recent Investor Day, 2021 is regarded to be a year of optimization at CLG. While our focus will continue to be on safety and well-being of our employees and contractors, we recognize that additional logistical and cost factors related to COVID-19 will remain with us for the entire year. Furthermore, we remain closely engaged with the community to continue improving their quality of life and to prevent a pandemic outbreak. And with that as a foundation, we continue progress toward consistent production and further improvement in CLG's cost performance. We also expect multiple exploration programs at the LGJV to result in meaningful exploration success. We are confident that our efforts, experience, and ownership of the expansive Los Gatos district should yield progressive growth in the Company's resource base and metal production for decades"

Mr. Orr concluded: "Gatos Silver has had an outstanding start since its launch as a public entity. We are delighted with the results of the efforts by everyone involved with this great company, from employees to contractors to members of the local community with which we have built a mutual bond of trust and support. We thank our joint venture partner Dowa for its strong partnership, our talented Board of Directors for their insight, and our incredible shareholders for their great support. We understand our responsibility to continue building value and believe that Gatos Silver's ownership in the Los Gatos district makes the Company a unique silver producer with unconstrained organic growth potential."
