FIREWEED ZINC MOBILIZES FIELD CREWS FOR
$10M DRILL PROGRAM AT MACMILLAN PASS
Vancouver, British Columbia: FIREWEED ZINC LTD. (“Fireweed” or the “Company”) (TSXV: FWZ;
OTCQB: FWEDF) is pleased to announce that the first field crews have been mobilized to the Macmillan
Pass Property, in Yukon, Canada to prepare for a large 2022 drill program. Significant improvements are
being made to the camp to support the four-rig 2022 program. Diamond drilling, core scanning, and a muon
tomography survey will begin in the coming weeks after the access road opens.
Highlights
• This will be Fireweed’s largest drill program to date with 8,000 m of diamond drilling planned.
• Two-thirds of the metres will be step-out and infill at Boundary Zone and Boundary West with the
remaining metres split between Tom and Jason targeting high-grade step-out and infill holes.
• All 2022 core plus core from previous programs and historical core will be scanned using advanced
hyperspectral scanning technology.
• Muon detectors will be deployed at Boundary West to effectively target step-outs and help define
the geometry of the recently discovered zones of massive and high-grade laminated sulphide.
• Field crews will also be conducting due diligence and validation work at the adjacent Mactung
Tungsten Project in the coming months in preparation for the planned Mineral Resource update
and PEA economic study
V.P. Exploration Statement
Gilles Dessureau, V.P. Exploration, stated “We are very excited to start our 2022 season. It will be the
largest and most ambitious program ever carried out by Fireweed at the Macmillan Pass Project. We are
also excited to use innovative new technologies, such as muon tomography and hyperspectral imaging to
guide exploration. The main objectives of the 2022 field program will be to define and expand the known
mineralized zones toward an updated mineral resource study this winter followed by an updated preliminary
economic study.”
2022 Diamond Drill Program
The 2022 drill program will consist of 4 diamond drill -rigs, targeting approximately 8,000 m of drilling
divided between the zones. Boundary Zone is open in every direction, and the 2022 program has been
designed to test step -outs around the peripheries of Boundary Main and Boundary West, in addition to
testing a potential connection between the two zones. The step-outs will include testing potential down-dip
continuation of the recently discovered high-grade stratiform mineralization at Boundary West (see
2 of 4
Fireweed news release dated March 10, 2022), and testing for additional massive sulphide mineralization
in the near -surface. Three of the rigs will remain at Boundary Zone where Fireweed anticipates drilling
approximately 5,800 m.
The fourth rig will drill Tom West, Tom North, Jason Main, and Jason South, targeting approximately 2,300
m between these four large zinc-lead-silver deposits. The holes at Tom West will focus on providing infill
within high -grade zones where the current mineral resource is supported by small-diameter historic
diamond drill holes with very poor recovery in the higher -grade portions of the holes . Fireweed sees
potential to increase zinc, lead, and silver grades in these areas by drilling large HQ diameter holes using
triple-split tubes to improve recovery, as demonstrated in previous Fireweed drill programs (see Fireweed
news releases dated October 10, 2018; November 13, 2018; August 20, 2019; September 10, 2019). The
drilling at Tom North will target a step-out of the near-surface mineralization that is potentially amenable
to open-pit mining. The drilling at Jason Main and Jason South will target high-grade step-outs
By the end of the 2022 campaign, Fireweed will have four seasons worth of new drill data that will be used
to inform a new global mineral resource, including an inaugural resource for the Boundary Main, Boundary
West, End Zone and Tom North zones, and an updated resource for Tom West, Tom East, Tom Southeast,
Jason Main and Jason South zones. Fireweed will use the new resource to inform a new P reliminary
Economic Assessment (PEA) for the project.
2022 Core Scanning Program
Fireweed contracted GeologicAI to scan all 2022 drill core as well as a significant portion of the core from
Fireweed’s past programs and some of the historic core from the previous operators. The scanning will
include high resolution digital photography, LiDAR topography, shortwave, visible, and near infrared
hyperspectral imagery, and X-ray fluorescence (XRF) scans. Fireweed anticipates using t his information
to inform g eometallurgical models of the deposits that have potential to deliver value by optimizing the
upcoming PEA.
2022 Muon Tomography Survey
Working with Ideon Technologies, Fireweed will deploy muon detectors in two drill holes at Boundary
West. These detectors will be used to define the geometry of the known zinc mineralization at Boundary
West and target additional mineralization in the area . Muon tomography is a down-hole geophysical
technique that uses naturally occurring cosmic-ray muons to measure density contrasts and identify
subsurface anomalies such as dense bodies of zinc mineralization.

About Fireweed Zinc Ltd. (TSXV: FWZ; OTCQB: FWEDF; FSE:20F ): Fireweed Zinc is a public
mineral exploration company on the leading edge of Critical Minerals project development. The Company
has three projects located in northern Canada:
• Macmillan Pass Zinc -Lead-Silver Project: Fireweed owns 100% of the district -scale 940 km 2
Macmillan Pass project in Yukon, Canada, which is host to the Tom and Jason zinc-lead -silver
deposits with current Mineral Resources and a PEA economic study (see Fireweed news releases
dated 10th January 2018, and 23rd May 2018, respectively, and reports filed on www.sedar.com for
details) as well as the Boundary Zone, Boundary Zone West, Tom North Zone and End Zone which
have significant zinc-lead-silver mineralization drilled but not yet classified as mineral resources.
The project also includes large blocks of adjacent claims with known showings and significant
3 of 4
upside exploration potential. Plans for 2022 include a large drill program toward expanded mineral
resources and an updated PEA to include large new zones of mineralization defined since 2018
including the Boundary Zones.
• Mactung Tungsten Project: The Company has a binding Letter of Intent to acquire 100% interest
in the 37.6 km2 Mactung Tungsten Project located adjacent to the Macmillan Pass Project. Mactung
contains historic resources that make it one of the largest and highest-grade undeveloped tungsten
resources in the world. Located in Canada, it is one of the rare large tungsten resources outside of
China. Plans for 2022 include due diligence and validation work on historic data in order to support
a new mineral resource estimate followed by a Preliminary Economic Study.
• Gayna River Zinc-Gallium-Germanium Project: Fireweed has 100% of the 128.75 km2 Gayna
River project located 180 kilometres north of the Macmillan Pass project. It is host to extensive
critical minerals mineralization including zinc, gallium and germanium as well as lead and silver,
outlined by 28,000 metres of historic drilling and significant upside potential. Plans for 2022 consist
of an airborne LiDAR topography survey, ground geophysics survey, and historic data compilation.
