Metallic Minerals Intercepts 144.5 Meters of 41.4 g/t Ag Eq as Bulk-Tonnage Ag-Pb-Zn Zone Emerges as Resource Target at Fox in East Keno, Keno Silver Project, Yukon, Canada

VANCOUVER, BC / ACCESSWIRE / January 12, 2023 / Metallic Minerals Corp. (TSX.V:MMG)(OTCQB:MMNGF) ("Metallic Minerals" or the "Company") is pleased to announce initial assay results from the 2022 field program at the Keno Silver project located in the historic Keno Silver district of the Yukon; Canada's most important silver mining district. These results cover the East Keno area and represent the first in a series of results to be released from the Company's 2022 exploration program, which included 3,265 meters (m) of diamond core drilling in 23 drill holes focused on expansion of advanced stage, "resource-ready" targets in anticipation of an inaugural NI 43-101 mineral resource estimate in 2023.

Exploration in 2022 at East Keno focused on drilling of the Greater Fox area targets (Fox, UKHM and Zone 2) first discovered by the Company in 2020, through systematic exploration efforts including mapping, geochemical soil sampling, geophysics, and drilling (see Figure 1). This work outlined the first known occurrence of Ag-Pb-Zn sheeted veins and includes the widest intervals of continuous mineralization ever reported in the Keno Hill silver district at up to 177 meters thickness. The sheeted vein mineralization (spaced distinct parallel Ag-Pb-Zn veins) at Fox is found in geologic settings that may be repeated as significant additional targets across the property which, as yet remain undrilled. The East Keno target areas of Fox, UKHM and Zone 2 have become substantial advanced-stage targets, poised for further expansion drilling and near-term resource delineation.

2022 East Keno Exploration Highlights

• Mineralization was intercepted in each of the eight holes (1,386 m) drilled at East Keno in 2022 (see Table 1). Both bulk-tonnage and high-grade Ag-Pb-Zn vein-style mineralization was encountered.
• Drill intercepts at the Fox target in 2022 averaged 136 m of sheeted vein mineralization (including up to 177 m wide); a significant broadening of the identified mineralized zones encountered in 2020 and 2021 drilling at Fox.
• At the Fox target, hole FOX22-03, returned sheeted vein zones of 144.5 m @ 41.4 g/t silver equivalent (Ag Eq), including 27.66 m at 105.8 g/t Ag Eq.
• A total of 107 high-grade samples (over 100 g/t Ag Eq and greater than 0.5 m in width) were intercepted in in the 2022 East Keno drilling, including:
  • Z222-01, 0.5 m @ 222.7 g/t Ag Eq (182 g/t Ag, 1.10% Pb, 0.03% Zn)
  • FOX22-02, 0.5 m @ 806.9 g/t Ag Eq (555.0 g/t Ag, 3.24% Pb, 3.14% Zn)
  • FOX22-03, 0.59 m @764.0 g/t Ag Eq (463.0 g/t Ag, 0.23 g/t Au, 0.79% Pb, 5.41% Zn)
  • UKHM22-01, 0.55 m @1087.0 g/t Ag Eq (953.0 g/t Ag, 3.56% Pb, 0.28% Zn)

Metallic Minerals President, Scott Petsel, stated, "The 2022 drilling at Fox is indicative of the huge potential at East Keno and has significant implications for further exploration success and future resource development. The sheeted Ag-Pb-Zn vein system identified at Fox had not been recognized in the district prior to Metallic's systematic exploration efforts and our team has since identified additional new areas as potential hosts of similar mineralization. We have now extended mineralization at the Fox deposit over 300 m along strike and 150 m down-dip starting from surface, where it remains open in all directions. A total of 18 drill holes define the Fox zone and show good continuity of the broader mineralized system with a relatively shallow dip. Resource modelling is currently underway focused on the large-scale bulk-tonnage resource potential for the Fox target area."

"The Company expects to announce additional drill results from both the Keno Silver Project (Primarily at advanced stage targets Formo and Caribou) and the La Plata Cu-Ag Project over the coming weeks and we look forward to discussing these and other developments at events throughout Q1."

East Keno Target Areas - Fox, Zone2 and UKHM

The East Keno area is represented by 15 multi-kilometer scale soil and geophysical anomalies which indicate additional potential for broad-scale mineralization in the least explored part of the Keno Hill silver district. Five of these anomalies have been drilled with initial positive results and an additional five other targets are drill ready. The Fox target, now with 2,748 meters drilled in 18 holes over three years, will be the focus of continued expansion and resource definition drilling in future programs.

Exploration of the East Keno area by Metallic Minerals began in 2018 with soil geochemical sampling and progressed to initial reverse circulation drilling in 2020 which returned several significant high-grade Ag-Pb-Zn sulfide vein intervals (KE20-01 0.77m @ 1,397 g/t Ag Eq) and numerous broad bulk-tonnage scale intervals (KE20-01, 28.2 @ 64 g/t Ag Eq and KE20-02, 22.1 m @ 48 g/t Ag Eq). The 2021 field program in East Keno combined additional reverse circulation drilling and initial diamond core drilling in warranting additional confidence in the target areas.

Drilling combined with extensive mapping and other geologic data has demonstrated a transition at East Keno from north to south from typical Keno style Ag-Pb-Zn mesothermal mineralization at Fox to mixed mesothermal and epithermal styles of mineralization at Zone 2 and UKHM. Epithermal mineralization is often associated with higher silver grades as demonstrated on the west side of the district at Silver King and Husky SW. The broad zones of mineralization at Fox, are now recognized as shallow dipping high-grade sheeted mesothermal Ag-Pb-Zn veins that appear to be associated with a regional scale thrust fault structures. This is a target concept that is broadly repeated across the district, and more specifically at multiple untested targets in the East Keno area.

Mineralized widths from the 2022 drilling on the Fox target returned the widest zones of continuous mineralization ever reported in the Keno Hill silver district and on a grade thickness basis are comparable in contained metal with some of the richest zones from the western part of district (see detailed 2022 results in Table 1 below). The Fox deposit sits within a multi-kilometer scale silver-in-soil anomaly leaving significant room to grow the footprint of mineralization for the Fox target both laterally and down dip. The westernmost drilling in the Fox target area, FOX22-05 and FOX22-06, demonstrates increasing widths of mineralization that will be tested in future programs along with untested areas of very high-level silver in soil values.

Drilling at the earlier stage Zone 2 and the UKHM targets have returned significant silver values including broad envelopes of mineralization similar to the Fox zone along with narrower high-grade silver intervals typical of the district. All drilling on these early-stage targets has been at shallow depths and these targets remain open for expansion with further drilling (see 2022 results in Table 1 below).

2022 East Keno Drilling

The focus of the 2022 drilling at Fox was extend known outlines of mineralization to enhance potential near-term resource opportunities. Single drill holes at UKHM and Zone 2 further confirmed these areas, both broad-scale mineralization and higher-grade epithermal style Ag-Pb-Zn veins, as priority targets for significant additional drilling and focus (See Figure 2).

Notes to reported values:

1. Ag equivalent is presented for comparative purposes using conservative long-term metal prices (all USD): $20/oz silver (Ag), $1.00/lb lead (Pb), $1.40/lb zinc (Zn).
2. Recovered Silver Equivalent in Table 1 is determined as follows: Ag Eq g/t = [Ag g/t x recovery] + [Au g/t x recovery x Au price/ Ag price] + [Pb % x 10,000 x recovery x Pb price / Ag price] + [Zn% x 10,000 x recovery x Zn price / Ag price].
3. In the above calculations: 1% = 10,000 ppm = 10,000 g/t.
4. The following recoveries have been assumed for purposes of the above equivalent calculations: 95% for precious metals (Ag/Au) and 90% for all other listed metals, based on recoveries at similar nearby operations.
5. Intervals are reported as measured drill intersect length.
