Metallic Minerals Announces High-Grade Silver Samples and 3D Modelling at its West Keno
Targets on the Keno Silver Project including Formo, Silver Queen and Duncan Creek
May 26, 2020, Vancouver, B.C., Metallic Minerals Corp. (TSX-V: MMG; US OTC: MMNGF) (“Metallic Minerals”, “Metallic”
or “The Company”) is pleased to report on exploration results and ongoing 3D modelling at the West Keno targets on its
100%-owned, 166 square kilometer Keno Silver project within the Yukon’s high-grade Keno Hill silver district. These results
focus on Keno Hill style high-grade silver-lead-zinc mineralization at the Formo, Silver Queen and Duncan Creek priority
target areas. Future news releases covering the Keno Silver project will report results from sampling and on-going
modelling work on the Central and East Keno target areas, which host additional priority exploration targets, that along
with Keno West will be the focus of the next phases of drilling.
Metallic Minerals’ Keno Silver property is the second largest land position in the historic Keno Hill silver district directly
adjoining the operations of Alexco Resources. The Keno Hill silver district is one of the world’s highest-grade silver districts,
with nearly 300 million ounces (“Moz”) of silver in past production and current M&I resources1,2, and excellent existing
infrastructure, including grid power, road access and nearby community services.
Highlights from West Keno include:
• Underground channel samples from the Formo target area show three high-grade mineralized shoots grading
more than 1,000 g/t silver equivalent (Ag Eq) grade that remain open to expansion (See figure below).
• Grades from the main Formo deposit returned an average of 7,459 g/t Ag Eq over 45 m lateral width on the
2800 level, 33 m lateral width grading 1,795 Ag Eq on the 2700 level and 44 m lateral width grading 2,258 Ag Eq
on the 2600 level with mineralization open to expansion (see Table 1 below).
• Identification of two adjacent high-grade mineralized shoots in underground sampling at Formo on the 2600
level that are open to expansion laterally and to depth.
• Definition of two new untested surface target zones have also been identified along the main Formo structure.
• Refinement of two priority drill targets at the Silver Queen target area down dip of Alexco Resources’ high-
grade Silver King deposit and trend extension of the Bermingham systems.
• Discovery of two new multi-kilometer soil anomalies at the early stage Duncan target area.
• Receipt of permits for drilling at Formo and Silver Queen in place with planning underway for the next phase of
exploration activities.
Greg Johnson, President and CEO, stated: “Following our key acquisitions in the Keno Hill silver district in 2017 and 2018
we have continued to integrate the extensive historic exploration data covering the district along with our new
geochemical and geophysical surveys in order to prioritize targets for step-out and first-stage drill testing following a
systematic approach to exploration. Our objective, through the integration of surface sampling, mapping, modelling of
drilling and geophysics, along with multi-spectral imagery, is to rapidly advance the most prospective targets to drill
testing and the development of new mineral resources in this proven, brownfields district. The Formo and Silver Queen
advanced stage target areas occur along known productive structural corridors that host some of the largest deposits in
the district and have the potential to quickly advance to the resource stage with additional drilling. In addition, the work
at the Duncan Creek target area has quickly developed a significant surface anomaly on trend with several important
productive structures. Metallic Minerals is well funded to be able to complete the next major milestones on our strong
portfolio of projects and we look forward to reporting on additional work from the Keno Silver project, as well as the
pending results from our recent La Plata project field programs.”
Introduction to the Keno Hill silver district and West Keno targets
Within the prolific, high-grade Keno Hill silver district, the western 12 kilometers (“km”) of the 35 km wide district has
seen the most intensive exploration and mining, including the major discoveries at the Bermingham and Flame & Moth
silver deposits by Alexco Resources (“Alexco”). Recent reconnaissance drilling results from Alexco, announcing the
discovery of the Inca deposit and the intercepted offset of the western extension of the Bermingham structural corridor,
continue to demonstrate the remaining exploration potential in the district through a systematic exploration process
along the productive mineralized trends.
Figure 1 - Keno Hill silver district geology and deposits
Metallic Minerals’ holdings directly adjoin Alexco’s operations and include 8 past producing deposits that were some of
the highest-grade deposits in the district. These deposits had only very shallow surface mining mostly from the 1920s and
30s and represent excellent targets with modern exploration tools. The Company’s holdings in the western Keno Hill
silver district occur along extensions of major structural corridors that host the Silver King, Elsa, and Hector-Calumet
deposits, which are some of the largest silver producers in the district (see Figure 2 below). The figure also highlights the
recent discoveries by Alexco at Bermingham, the western Bermingham extension, Inca and Flame & Moth.
Figure 2 - West Keno Targets at the Keno Silver Project, showing the Formo, Silver Queen, and Duncan Creek target
areas in relation to historic mines and new resources in the Keno Hill silver district
The largest deposits in the district are hosted primarily in the Keno Hill quartzite and Triassic greenstones along major
structural corridors where the structural setting allows for the development of significant Keno Hill type high-grade silver-
lead-zinc rich vein deposits. The schematic section shown on Figure 3 below, illustrates the major deposit locations along
the Bermingham and Elsa trends, two of the most productive structural corridors. This figure also shows the similarity of
the Silver Queen and Formo target areas to the stratigraphic and structural settings at the Bermingham and Sadie Ladue
deposits.

Queen and Formo targets
Formo Target Area
The Formo advanced stage target area hosts the historic Formo mine, which produced silver at various times since the
1930s from high-grade vein structures that graded an average of 5,092 g/t silver1. The majority of this historic production
came from an open pit adjacent to the Silver Trail highway between the Elsa townsite and Keno City. At Formo a total of
1.2 km of exploration drifting on three levels were developed with connected vertical raises that outline silver -lead-zinc
mineralization down to a depth of approximately 100 m from surface. Historic drilling included six diamond core holes
(1,988m) along with 54 percussion holes (2,647m) (see Figure 4 below).
At least three vein structures, hosted primarily in greenstones below the main Keno Hill quartzi te unit, have been
identified at Formo in underground sampling, drilling and trenching. These structures are located two kilometres
northeast of the historic Hector-Calumet mine, which was the largest silver producer in the district producing nearly 100
Moz of silver. The Formo deposit occurs along a splay of the Hector -Calumet structure where it intersects the Elsa
structural trend, which was the second largest silver producer in the district (see Figures 1 and 2). The deposit setting for
Formo is geologically similar to the greenstone hosted Sadie Ladue mine (12.7 Moz of silver at 1,781 g/t Ag) and Keno Hill
mine (12.6 Moz of silver at a grade of 1,520 g/t Ag), two of the district’s highest grade deposits1 (see Figure 3 Long Section
above).
Figure 4 - 3D model showing the high -grade Formo target composite channel sample grades from underground levels
below the historic Formo surface mine
Recent modelling of results at Formo by Metallic Minerals have integrated the surface, underground and drill related
sampling into a 3D geologic model along with high-resolution orthophotography, multi-spectral studies and newly
interpreted geophysical surveys covering the area. Figure 3 highlights the mineralized shoots at the Formo deposit in long
section view. Between the open-pit surface exposures and the 2600 level drift, the vein has been delineated by channel
sampling from underground drifts and drilling for approximately 100 meters vertically and 200 meters laterally. This
modelling reveals at least three well-defined mineralized shoots of high-grade silver grading over 1,000 g/t silver. These
mineralized shoots remain open to expansion at depth and along strike and extensions of these shoots will be the focus
of future drilling (see Table 1 and Figure 4).
Sampling from the main mineralized shoot under the historic Formo open pit shows an average grade of 7,459 g/t Ag Eq
over 45 m lateral width in 5 samples, on the 2800 level, 33 m lateral width grading 1,795 g/t Ag Eq on the 2700 level and
44 m lateral width grading 2,258 g/t Ag Eq on the 2600 level with mineralization open to expansion at depth (see Table 1
below).
Sampling on the 2600 level also shows two additional high-grade mineralized shoots along the southwest-northeast trend
of the main mineralized structure. The first zone includes 25 m lateral width averaging 3,078 g/t Ag Eq. ending in
mineralization and open to the southeast and to depth. Adjacent to this are two zones of mineralization of 69 m grading
580 g/t Ag Eq. and 70 m 850 g/t Ag Eq on the 2700 and 2600 levels connecting to the main central shoot. A second 4 m
wide zone ending in high-grade mineralization on the 2600 level averages 3,092 g/t Ag Eq. and is also open to expansion
laterally to the northeast and to depth.

In addition to the mineralization at the main Formo deposit two new surface targets have been identified along the same
structural corridor within parallel greenstone sills. Additional 3D modelling is underway on these newly identified targets.
The opportunity to significantly expand the known mineralization at Formo defined from underground sampling and
drilling to date, as well as the potential to define new high-grade mineralized shoots along the main mineralized structural
corridor, makes this one of the top priority advanced stage targets on the Keno Silver project.
The previously pending Class 3 permit covering the Formo claims has been granted and the Formo target is prioritized for
drilling during the next phases of work on the property.
Silver Queen Target
The Silver Queen target area is located at the western end of the Keno Hill silver district adjacent to Alexco's Silver King
mine, which produced 11 million ounces of silver at an average grade of 1,800 g/t1 in the 1920s and 30s (See Figure 2 Map
and Figure 3 Long Section). Production at Silver King came from both underground and open pit mine sources hosted in
Keno Hill quartzite. Six mineralized vein structures have been identified that host a historic resource of 5.3 million ounces
of silver at an average grade of 1,373 Ag g/t2.
Modelling at the Silver Queen target area by Metallic Minerals has refined two priority targets for drill testing that include
the potential projected down dip extension of the high-grade Silver King deposit and the trend extension of the western
Bermingham system. Both structural corridors represent significant near-term exploration targets at Silver Queen (See
Figure 5 Silver Queen Cross Section below).
Figure 5 - Cross section through the Silver Queen target showing major mineralized structural corridors and targets
Recent nearby reconnaissance drilling by Alexco in 2018 and 2019 successfully discovered the western Bermingham
extension, intercepting multiple high-grade Keno Hill type vein structures across what is believed to be the offset of the
main Bermingham structural corridor by the Brefault structure3. The Bermingham deposit includes 33 million ounces of
measured and indicated silver along with 11 million ounces of inferred resources that are hosted in the Keno Hill quartzite
and that remain open at depth and along trend to the southwest, making it the second largest deposit in the district2. The
Figure 2 plan map shows the western offset Bermingham system drilling and its potential strike onto the Silver Queen
target area.
Work by Metallic Minerals at Silver Queen has included the completion of soil sampling, detailed surface magnetic and
VLF geophysics, reprocessing and interpretation of regional geophysics, and 3D modelling. The geophysical surveys
indicate a 400m wide resistive body of potential quartzite and grit dominant lithology that is overlain by anomalous soil
geochemistry that may indicate the presence of the projected structural corridor. New processing and interpretation of
regional geophysics shows a spatial relationship between deep structural features at Keno Hill and some of the largest
deposits in the district with a similar pattern seen at Silver Queen.
A class 3 permit covers Silver Queen and this drill ready target is highly prospective to host extensions of the high-grade
silver mineralization seen at Silver King and Bermingham.
Duncan Creek Target
The early stage Duncan Creek target area covers the southwestern extensions of several major mineralized trends
including the Flame & Moth and several parallel structural corridors and is located 8 km by road from Keno City. Duncan
Creek was one of the first areas that attracted prospectors to the area in 1898 with an estimated 40,000 ounces of placer
gold production and two placer operations that are still active along the creek and its tributaries.
Work by Metallic Minerals at this new early stage target area has led to the discovery of two new multi-kilometer soil
anomalies on trend with projected structural corridors. The Company plans to complete additional surface sampling and
mapping along with a detailed magnetic and VLF geophysical survey to refine targets at the Duncan Creek target area in
preparation for potential reconnaissance drilling in the next stage of evaluation.
District Summary
Exploration by Metallic Minerals continues to systematically build on the Company’s 3D geologic database covering the
east, central and western portions of the Keno Hill silver district with a total of 81 drill holes completed on the Keno Silver
project to date. Exploration by the Company has advanced three targets in the central and western parts of the district
to step-out drilling stage and several additional targets to drill-ready status along the known historically productive trends
that are on strike with past-producing mines. In addition, recent exploration has refined and expanded 10 new priority
multi-kilometer-scale early-stage targets for reconnaissance drilling in the under-explored eastern part of the district
along where highly elevated silver, lead and zinc in soils and high-grade rock samples have been identified.
Metallic Minerals will be reporting additional results from its expanded East Keno sampling programs and geophysical
survey interpretation in coming weeks. Planning is underway for the next phase of exploration in 2020 and the Company
is well funded to advance the Keno Silver project to the next major milestones at both its advanced stage and early stage
targets.
