Gatos Silver Announces Initiation of Exploration Drilling in the Los Gatos Region

December 16, 2020

DENVER--(BUSINESS WIRE)-- Gatos Silver, Inc. (NYSE/TSX: GATO) (“Gatos Silver” or the “Company”) is pleased to announce the reactivation of drilling through three separate programs that are collectively estimated to require 58,000 meters of exploration and definition drilling at an expected cost of $6.1 million.

Cerro Los Gatos Infill and Extensional Drilling Program

The first program is an infill and extensional drilling program at the Cerro Los Gatos deposit within the Los Gatos District Joint Venture (“LGJV”) between the Company and Dowa Metals and Mining Co., Ltd.

The Cerro Los Gatos measured and indicated (“M&I”) resources are currently comprised of 10.4 million tonnes at 269 g/t silver, 5.5% zinc, 2.7% lead and 0.34 g/t gold. Within the M&I resources, 9.6 million tonnes are classified as proven and probable reserves and incorporated into the current mine plan. This latest program will target the inferred resources depicted in Figure 1 with drilling to start in the SE3 block of the deposit. The Cerro Los Gatos mineralization remains open to the northwest and southeast along the deposit’s strike trend. Gatos Silver expects this program to convert a substantial portion of the current inferred resources to M&I and discover additional inferred resources. Once completed, the Company intends to incorporate the additional M&I resources into a new mine plan that will increase the proven and probable reserves and further support a possible expansion of Cerro Los Gatos’ production rate from 2,500 tpd to 3,000 tpd.

Drilling began on December 5, 2020 and the LGJV expects this program to cost about $2.8 million for this 27,000-meter definition and extension drilling program with completion anticipated by June 2021.

Los Gatos District Resource Expansion

In early 2021, the LGJV intends to initiate a second $2.7 million exploration program to expand resources throughout the Los Gatos District. The initial target is an estimated 19,000-meter campaign at the Esther mineralized zone, to expand its initial NI 43-101 compliant indicated resource of 0.46 million tonnes at 133 g/t silver, 2.1% zinc, 0.7% lead and inferred resource of 2.29 million tonnes at 98 g/t silver, 3.0% zinc, and 1.6% lead. Esther is located about four kilometers from Cerro Los Gatos and contains similar styles of mineralization and geochemistry. The Company believes that further drilling may materially expand the size and mineral tenor of this resource.

Santa Valeria Project

In early 2021, Gatos Silver also plans to start a concurrent 5,400-meter exploration program on its wholly owned Santa Valeria project outside the LGJV (see Figure 2). 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 within the LGJV. Santa Valeria is geologically comparable to Cerro Los Gatos and may contain similar mineral content.

Stephen Orr, the Company’s Chief Executive Officer, said: “The commencement of this extensive program continues Gatos Silver’s commitment to create value through advancement of its exceptional assets. The multiple identified zones of mineralization located in the highly prospective Los Gatos District position the Company to add substantial new resources on the extensive LGJV mineral rights package as well as its 100%-owned mineral rights at Santa Valeria. We are looking forward to deploying a portion of Gatos Silver’s recently raised funds to continue building upon our exploration success through identifying additional areas of mineral endowment and further upgrading the existing resource inventory.”

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.
