Metallic Minerals Drills 4.6 Meters of 983 g/t Silver Equivalent at the Keno Silver Project in Yukon, Canada

VANCOUVER, May 26, 2022 - Metallic Minerals (TSX.V:MMG)(OTCQB:MMNGF) ("Metallic Minerals", or the "Company") is pleased to report the final set of assay results from its 2021 drilling completed at the Company's 100%-owned, 166-square-kilometer Keno Silver Project located within the historic, high-grade Keno Hill silver district in Canada's Yukon Territory. These drill tests were targeted at extending high-grade silver-gold-lead-zinc mineralization at the Formo deposit in the West Keno target area, one of several advanced stage targets moving toward an initial NI 43-101 mineral resource estimate for the Keno Silver project.

Highlights

• Drilling in 2021 and 2020 by Metallic Minerals at the Formo deposit intercepted both high-grade Keno-style Ag-Au-Pb-Zn veins and broader zones of potentially bulk mineable mineralization.
• FOR21-05 returned three intervals at over 1,000 g/t silver equivalent ("Ag Eq") from 92.7 m to 115.5 m for a total of 22.8 m grading 219.5 g/t Ag Eq including 0.5 m of 1,657.8 g/t Ag Eq with up to 17 g/t Au, 0.7 m of 1,408.8 g/t Ag Eq and 0.5 m of 1,649.9 g/t Ag Eq.
• FOR21-06 intercepted multiple zones of mineralization with 4.6 m of 938.3 g/t Ag Eq including 3,229.9 g/t Ag Eq over 1.0 m within a broader zone of 11.4 m grading 413.7 g/t Ag Eq.

The Formo target area hosts multiple parallel vein structures and mineralized zones within a broader structural envelope that remains open to expansion and shows excellent opportunities for resource delineation. Results from 2021 drilling intercepted extremely high grades, including FOR21-05 returning three intervals over 1,000 g/t silver Ag Eq and FOR21-06 with 3,229.9 g/t Ag Eq over 1.0 m within an interval of 4.6 m of 938.3 g/t Ag Eq (see Table 1 below). Both zones were encountered at shallow depths of less than 150 m down hole and these intersections extend high-grade silver mineralization below the 2020 drilling and the historically productive Formo mine. Geophysical and geochemical surveys, enhanced by the 2021 fieldwork, demonstrate significant resource potential opportunities in the Formo target area.

The Formo vein structure lies at the intersection of a north-easterly extension of the Bermingham-Calumet and the Elsa vein system, which are hosts to the some of the largest historic producing mines and current resources and reserves in the Keno Hill silver district (see Figure 1). The Formo Target remains open for expansion along trend and down dip and has several untested surface targets.

Metallic Minerals President, Scott Petsel, stated, "These exciting results from this most recent follow-up drilling program at the Formo target area in the western Keno Hill District, combined with the exceptional 2020 drill results, demonstrate the potential to delineate significant, high-grade resources at the Keno Silver project. Our team has done remarkable work to build on our understanding of the geology and the important controls to mineralization in the highly productive Keno Hill silver district."

"As we prepare to embark on our upcoming exploration campaign, we recognize the importance of moving toward the definition of an inaugural resource estimates at Keno Silver, with Formo and Caribou being the two most advanced in that regard. We are also very focused on and enthusiastic about conducting robust follow-up work on our recent discoveries of both high-grade silver veins and bulk mineable mineralization in the East Keno area. We expect to provide updates with respect to planned programs at both Keno Silver and the La Plata project in Colorado over the coming weeks and look forward to meeting with investors during the upcoming Prospectors and Developers Conference in Toronto in mid-June."

West Keno Exploration Program and Formo Target

The Western Keno Hill district is host to the largest historic production and current resources in the prolific Keno Hill silver district. The Formo target is located at the intersection of a north-easterly structural zone extending from the Hector-Calumet mine, which was the largest producer in the district producing nearly 100 million ounces of silver and the Elsa structural trend, which was the second largest silver producer in the district (see Figure 2). The historic Formo mine produced silver at various times since the 1930s from high-grade vein structures that graded an average of over 5,000 g/t silver¹. The majority of this historic production came from an open pit located alongside of the Silver Trail highway between the Elsa townsite and Keno City.

Metallic Minerals' exploration efforts at the Formo target area have integrated recent drilling with surface and underground sampling into a 3D geologic model, along with multi-spectral studies and geophysical surveys covering the area (see Figure 3). In addition to the mineralization at the known Formo deposit, two new surface targets have been identified through surface soil and rock sampling along the same structural corridors that show potential to host high-grade and bulk tonnage Keno-style Ag-Au-Pb-Zn. The opportunity to significantly expand the known mineralization defined from underground sampling and surface drilling, as well as the potential to define new high-grade deposits along the main mineralized structural corridor, positions Formo as a top priority target for near-term resource definition at the Keno Silver project.

Silver equivalent (Ag Eq) values assume Ag $19/oz, Pb $1.05/lb, Zn $1.30/lb, Au $1,800/oz and 100% metallurgical recovery. Sample intervals are based on measured drill intersect lengths and are believed to be representative of true widths.

About Metallic Minerals

Metallic Minerals Corp. is a growth-stage exploration company, focused on high-grade silver and gold projects in underexplored, brownfields mining districts of North America. Our objective is to create shareholder value through a systematic, entrepreneurial approach to exploration in the Keno Hill silver district, La Plata silver-gold-copper district, and Klondike gold district through new discoveries and advancing resources to development. Metallic Minerals has consolidated the second-largest land position in the historic Keno Hill silver district of Canada's Yukon Territory, directly adjacent to Alexco Resource Corp's operations, with nearly 300 million ounces of high-grade silver in past production and current M&I resources. In addition, exploration at the recently acquired La Plata silver-gold-copper project in southwestern Colorado is targeting a silver and gold-enriched copper porphyry and adjacent high-grade silver and gold epithermal systems. The Company also continues to add new production royalty leases on its holdings in the Klondike gold district in the Yukon. All three districts have seen significant mineral production and have existing infrastructure, including power and road access. Metallic Minerals is led by a team with a track record of discovery and exploration success on several major precious and base metal deposits, as well as having large-scale development, permitting and project financing expertise.
