2022

March 10, 2022, Vancouver, B.C., Metallic Minerals (TSX.V: MMG | US OTCQB: MMNGF) (“Metallic Minerals”, or the “Company”) is pleased to announce final results of the 2021 exploration program at the La Plata silver-gold-copper project in southwestern Colorado within the prolific Colorado Mineral Belt. The campaign was successful in its primary goal of confirming the tenor of mineralization as reported in drill results from Rio Tinto, Freeport and others at the main Allard porphyry target. With that confirmation complete, Metallic Minerals is further pleased to report it has engaged SGS Geoscience to develop an inaugural National Instrument 43-101 compliant mineral resource estimate from the combined database with delivery expected in the coming weeks.

Highlights

• Diamond drill holes completed within the main Allard zone porphyry target confirm historical drill results and add new gold, platinum and palladium data.
• SGS Geoscience has been engaged to complete inaugural NI 43-101 mineral resource estimate on the project based on 56 holes totaling 15,200 meters (“m”) drilled on the property to date.
• Exploration in 2021 included 1,980 meters of diamond drilling, resampling of historical drill core, underground sampling from the Allard tunnel and mapping and sampling across the broader property.
• Drill hole LAP21-01 intersected 380.39 m of 0.27% Copper Equivalent (“CuEq”) (0.21% Cu, 2.08 g/t Ag, 0.025 g/t Au), including multiple significant intervals of higher-grade mineralization (see Table 1).
• Drill hole LAP21-02 intersected 416.28 m of 0.28% CuEq (0.23% Cu, 2.57 g/t Ag, 0.026 g/t Au), including, 128.02 m of 0.45% Cu Eq (0.38% Cu, 4.19 g/t Ag, 0.042 g/t Au).
• Allard tunnel sampling returned 98.2m of 0.55% CuEq (0.46% Cu, 4.75 g/t Ag, 0.03 g/t Au), including 61.6 m of 0.65% CuEq (0.55% Cu, 5.55 g/t Ag, 0.03 g/t Au).
• Historical drilling by Rio Tinto, Freeport and others returned intervals in the Allard porphyry system, starting at surface, that include 395 m grading 0.57% copper equivalent (0.51% Cu, 6.3 g/t Ag and 0.017 g/t Au) in LP-03 and 854 m at 0.26% Cu including 254 m grading 0.41% Cu in drill hole LP-01, both of which ended in mineralization.
• The mineralized system remains fully open to expansion at depth and along strike.

Metallic Minerals Chairman & CEO, Greg Johnson, stated, “Metallic Minerals is the first company to complete significant exploration on the La Plata project in nearly 50 years, applying modern technologies and deposit modeling techniques. Since acquiring the project in 2019, the Company has recognized and advanced the potential to rapidly extend the size of the known mineralized system, and to identify and expand the higher-grade zones within the broader porphyry and epithermal mineralized zones.

As a culmination of these efforts, the results from the 2021 drilling and sampling program have confirmed the significant tenor and scale of mineralization at the Allard target area and have enabled us to advance to an inaugural NI 43-101 resource estimate on the project. This new drilling has further allowed us to refine our understanding of the styles and controls to mineralization at the Allard system and has identified a potential new porphyry center at the adjacent Copper Hill target area (see Cross Section in Figure 1). The new resources at the Allard target area will cover a relatively small part of the 33 km2 property that remains highly prospective for new discoveries.”

Mr. Johnson continued, “Looking ahead, through our ongoing collaboration with the team at Goldspot Discoveries using their proprietary Artificial Intelligence (“AI”) machine learning technology, we are developing vectors to target areas for resource expansion at the Allard and Copper Hill target areas. To date, we have identified 16 new high-grade epithermal-style and porphyry-style mineralized zones across the broader property for follow-up work during the 2022 field season. The modelling work for the resource estimate on the Allard target is underway and we look forward to reporting the results over coming weeks, as well as further drill results from the Keno Silver project.”

2021 Exploration Program

Exploration work in 2021 included 1,980 meters of diamond drilling, resampling of historical drill core and underground sampling from the Allard adit, along with mapping and sampling across the broader property. New core drilling was targeted to test the Allard porphyry center in proximity to the Allard adit, verifying spatial continuity and tenor of the copper, silver and gold mineralization. Channel sampling across the historic underground Allard adit, with modern analytical methods, compared closely with historic results and confirmed higher grade intervals of up to 0.65% CuEq over 61.6 m (0.55% Cu, 5.55 g/t Ag, 0.03 g/t Au).

This year’s work, combined with the historic drilling, recent geophysical surveys (Airborne MT and ground-based IP), remote sensing, field mapping and surface geochemical sampling has helped to expand the scale of known targets and identify new untested centers for porphyry and epithermal mineralization. In addition, the application of expanded and new modern analytical techniques to areas previously only analyzed for copper has shown the potential for significant gold, palladium and platinum associated with the porphyry system, in addition to silver.

The main Allard mineralized porphyry system has been drill tested over an area of 3 km x 1 km and shows more than a kilometer of vertical extent. The system remains open to expansion at depth and along trend. An adjacent second porphyry center has been recognized at Copper Hill beneath an area of high-grade surface mining. An additional 16 potential porphyry and epithermal targets have been identified outside of the Allard and Copper Hill areas. Planning for exploration work in 2022 is currently underway to include resource expansion drilling, geophysics and follow-up exploration on newly identified targets.

About La Plata Silver-Gold-Copper Project

The road accessible La Plata project covers 33 km2 approximately 26 km northwest of Durango, Colorado within the historic high-grade La Plata mining district located at the southwest end of the prolific Colorado Mineral Belt. Mineralization is related to a large-scale precious-metals-rich porphyry copper system with associated high-grade silver and gold epithermal vein and replacement deposits.

The La Plata district has a long and rich history of mining with the first silver deposits discovered in the 1700s by Spanish explorers. High-grade silver and gold production has been documented from the 1870s through the early 1940s from vein structures, replacement bodies and breccia zones at over 90 individual mines and prospects1. Historical production from some of these high-grade structures exceeded 1,000 grams per tonne (“g/t”) silver and over 15 g/t gold with some of the richest deposits delivering true bonanza grades for silver and gold.

From the 1950s to 1970s, major miners including Rio Tinto (Bear Creek) and Freeport-McMoRan (Phelps Dodge) explored in the La Plata district focusing on the significant potential for bulk-tonnage disseminated and stockwork hosted mineralization2. Freeport-McMoRan retained ownership of claims in the district until 2002 when they sold their holdings to the current underlying vendors during the lows of the last metal price cycle.

A total of 56 drill holes, totaling 15,200 m, have been drilled on the property since the 1950s which confirms the presence of a large-scale, multi-phase porphyry system with significant silver, gold and copper. This large-scale mineralized system is associated with a 10 km2 strongly magnetic signature with intense hydrothermal alteration.
