DENVER–(BUSINESS WIRE)– Gatos Silver, Inc. (NYSE/TSX: GATO) (“Gatos Silver” or the “Company”) is pleased to report drilling results on its definitional drilling at Cerro Los Gatos (“CLG”) and the commencement of drilling at the CLG’s Esther zone.

Figure 1: Plan View of the SE Zone Drill Hole Map, Block 4 of the Cerro Los Gatos System

The 2021 CLG definition drilling campaign continues to identify additional mineralization both on the Southeast (“SE”) and Northwest (“NW”) extensions of the deposit beyond the present reserve blocks. Since the definition drilling program began in late 2020, 23 holes have been completed in the SE zone and eight holes have been completed in the NW zone.

Stephen Orr, Chief Executive Officer, stated, “The initial drilling in CLG’s SE and NW zones is successfully upgrading the 3.7 million tonnes of Inferred resource to the Measured and Indicated category. Furthermore, the identification of additional offsets to a recently discovered new SE zone vein has extended the CLG mineralization beyond the current resource model and demonstrated that the southeast extension of the deposit is still open along strike. Reactivation of drilling at Esther represents another significant milestone for the Los Gatos District. Esther, which has an existing NI 43-101 resource, was discovered in 2011 and its initial exploration program was comprised of broadly spaced holes that indicated a mineralized zone with strong similarities to the CLG deposit. The current program will be focused on detailed definition of silver, zinc, lead and gold occurrence throughout this epithermal system. We expect to issue an updated NI 43-101 resource report in the first quarter of 2022.”

Highlights from the latest 13 drill holes, assays and principal findings are summarized below:

SE Zone

  • Hole GA385 intercepted 13.5m @236.0g Ag/T, 6.9% Zn, 6.3% Pb, and 0.29g Au/T, indicating a continuity of mineralization and increasing zinc and lead grades in the southeastern most offset to the main deposit. The hole also shows an increase in thickness from hole GA364 which was previously reported.
  • Two offsets of the new footwall vein, which was first identified in hole GA370, have been intersected with higher copper in holes GA378 and GA386.

NW Zone

  • Additional high-grade mineralization has been identified in holes GA382 where 3.1m @608.7g Ag/t, 2.1% Pb and 5.4% Zn was intercepted and GA384 where 4.3m @618.5 g Ag/t, 0.9% Pb and 2.9% Zn was intercepted.

SE Zone

The latest drill holes display mineralized intersections with the exception of hole GA 376, which was drilled along the fault separating Blocks 3 and 4 within the SE zone. Continuity of the vein complex geometry is maintained with all of the latest results.

In addition, a zone of higher-grade mineralization has been established with the previously reported hole GA364 and hole GA385 which are the largest offsets, expanding the SE zone over 425 meters from the reserve blocks to date (see Figure 1). Within Figure 1, the cluster of small blocks on the left side depicts the SE extent of CLG’s current Measured and Indicated resource. Hole GA385 is located up-dip from hole GA364 and indicates additional potential for higher grades and increased thicknesses at higher elevations in this area (see Figure 2).

NW Zone

An additional four holes have been completed near the NW end of the NW zone reserve blocks (see Figure 3). The holes demonstrate continuity of mineralization and show strong grades in holes GA382 and GA384 (see Figure 4).

Esther Zone

Drilling commenced at the Esther zone on May 7, 2021 with one drilling rig. The Esther zone is located 4.5km south of CLG on a parallel set of geologic structures. Mineralization occurs in a similar manner to CLG as banded quartz veins with galena, sphalerite and silver sulfides in three separate known veins. The present NI 43-101 Resource at the Esther zone, as calculated by Tetra Tech, is as follows:

Note: Based on a cut-off grade of 100 g/t silver equivalent using metal prices of $22.30/oz silver, $0.97/lb lead, and $0.91/lb zinc. Metallurgical recoveries were not considered.

Historical drilling at the Esther zone was comprised of 40 widely spaced holes drilled between 2009-2010 and represents only an initial phase of exploration. The 2021 program includes a plan for 59 holes at 50-meter spacing comprising 19,000 meters. The objective of the 2021 drilling is to convert Esther’s inaugural inferred resources into the Measured and Indicated category and use our enhanced knowledge of mineral deposition within these epithermal systems to explore for new resources in undrilled areas within the Esther zone.

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.
