Q4 and 2020 Production

During 2020, the CLG mine achieved steady improvement in its mining rates reaching 2,324 tonnes/day of production by year-end despite a Mexican government emergency health declaration and mandated temporary suspension in April and May. While CLG was able to adopt effective COVID-19 prevention protocols, mining activities were suspended until sufficient testing capabilities were implemented for the large mining labor complement. Mining activities resumed in early June 2020 and daily production progressively increased with COVID-19 prevention protocols fully implemented (see Figure 1).

Mine development was not impacted by the temporary suspension and has consistently exceeded plan since the initial commissioning of CLG. By the end of 2020, the mine had achieved just under 16,000 meters of development in the NW and Central Zones, providing ample ore access to maintain mining rates (see Figure 2 and Figure 3).

The CLG processing facility is highly automated and recommissioned quickly following the COVID-19 temporary suspension. Prior to the suspension, the processing facility had already demonstrated an ability to achieve its 2,500 tonne/day design processing rate. Post suspension, the plant throughput was controlled to match production from the mine. During 2020, the processing team focused on achieving high-quality concentrate and by year-end, average metal recoveries exceeded plan for the four payable metals (see Figure 4).

During 2020, CLG produced 4.2 million silver ounces in concentrate, 34.2 million zinc pounds in zinc concentrate, 27.4 million lead pounds in lead concentrate and 4.9 thousand gold ounces in lead concentrate.


In December 2020, Gatos Silver and its Los Gatos Joint Venture (“LGJV”) partner, Dowa Metals & Mining Co., Ltd. (“Dowa”), commenced a 27,000-meter exploration program to convert CLG’s established 3.2 million tonnes of inferred resources to the measured and indicated category and to discover additional resources along the northwest and southeast extensions of the CLG deposit. The LGJV also intends to reactivate Los Gatos District exploration in early 2021, starting with the Esther resource located four kilometers from CLG.

During the first quarter of 2021, Gatos Silver will begin a 5,400-meter exploration program on its wholly-owned Santa Valeria project. The Santa Valeria target has been developed through regional geologic work by Gatos Silver’s exploration team, which defined a large basin structure hosting the mineralization zones that reside within the LGJV land package. Santa Valeria is geologically comparable to CLG and may contain similar mineral content.

The commencement of this extensive program reaffirms Gatos Silver’s commitment to create value through advancement of its exceptional assets. The multiple prospective zones of identified mineralization located in the highly prolific Los Gatos District position the Company to add substantial new resources on the extensive LGJV mineral rights package and its 100%-owned mineral rights at Santa Valeria. Gatos Silver expects to extend its historical exploration success by identifying additional areas of mineral endowment and further upgrading the existing resources.

In late October 2020, Gatos Silver applied for public listing on the NYSE and TSX and successfully completed an initial public offering (“IPO”) of 24,644,500 shares, raising gross proceeds of US$172.5 million.

Stephen Orr, the Company’s Chief Executive Officer, said “We are delighted with Gatos Silver’s achievements to-date. The Company has created substantial value over the last decade by progressing the Los Gatos District from a single discovery to an entire new silver-dominant mineral district containing 14 zones of mineralization. Through its joint venture, it was able to finance, construct and commission CLG as its maiden mine in this prolific new district. By year-end, the Company reached a major milestone by successfully completing a precious metals IPO on the NYSE/TSX, the largest of its kind in the last decade.”

About Gatos Silver

Gatos Silver is a silver dominant exploration, development and production company that discovered a new silver and zinc-rich mineral district in southern Chihuahua State, Mexico. To-date, 14 zones of mineralization have been defined within the district and all are characterized by silver-zinc-lead epithermal mineralization. More than 85% of the approximately 103,087-hectare mineral rights package has yet to be drilled, representing a highly prospective and underexplored district. The Company recently built and commissioned its first operating mine and mineral processing plant at the Cerro Los Gatos deposit, which is expected to produce 12.2 million silver equivalent ounces annually.
