NEWS RELEASE
18th November 2021 TSXV: FWZ
Fireweed Intersects 1.54% Copper, 5.42% Zinc, and 5.7 g/t Silver over 2.00 m and
2.35% Zinc, and 4.6 g/t Silver over 203.05 m in Step-Out Hole at Boundary Zone
Vancouver, British Columbia: FIREWEED ZINC LTD. (“Fireweed”) (TSXV: FWZ) is pleased to
announce further results from the 2021 drilling program at the Macmillan Pass project, Yukon, Canada.
Results from this step-out hole continue to show that Boundary Zone is growing and expand the known
extent of the wide zones of vein-hosted mineralization.
Highlights
• A new, copper-rich style of mineralization was encountered in NB21-005, grading 1.54% copper,
5.42% zinc, 0.04% lead, and 5.6 g/t silver over 2.00 m.
• Step-out hole NB21-005 intersected a wide zone of vein hosted mineralization at Boundary Zone
grading 2.35% zinc, 0.01% lead, and 4.6 g/t silver over 203.05 m, extending the mineralized zone
to depth.
• The broader 203.05 m intersection included wide higher-grade zones such as 34.45 m of 4.61%
zinc, 0.01% lead, and 8.9 g/t silver.
CEO Statement
Brandon Macdonald, CEO, stated “These intriguing drill results show a new style of mineralization and
brings copper into the mix at Boundary Zone. This is an encouraging sign of the system becoming hotter
as we continue to expand the known zone of mineralization with more and more step-outs. This is the first
discovery of meaningful copper grades in core at the Macmillan Pass project and we are excited to follow
up on this new style of copper-zinc mineralization in the coming drill programs”.
Boundary Zone Drilling Results
Hole NB21-005 was drilled as a down-dip step-out to the known zinc mineralization at Boundary Main
and intersected 203.05 m of 2.35% Zn, 0.01% Pb, and 4.6 g/t Ag including wide zones of significantly
higher grade such as 34.45 m of 4.61% Zn, 0.01% Pb, and 8.9 g/t Ag and 38.54 m of 3.47% Zn, 0.01%
Pb, and 4.3 g/t Ag. Vein-hosted sphalerite and disseminated sphalerite mineralization was encountered
within conglomerates, mudstones and carbonate-altered mafic volcaniclastic rocks. A narrow, 2.00 m
intersection of copper-rich mineralization comprised brecciated rock with a network of thin pyrite-
sphalerite-chalcopyrite veinlets and graded 1.54% Cu, 5.42% Zn, 0.04% Pb and 5.7 g/t Ag – a style of
mineralization not previously encountered on the Macmillan Pass project. The copper-rich intersection is
located at a vertical depth of only 60 m from surface. Drill hole NB21-005 confirmed a large width for the
zone of zinc mineralization originally intersected in down-dip hole NB20-002 (see Cross Section A-A’).
Boundary Zone has now been tested to a vertical depth of approximately 350 m and the mineralized zone
remains open at depth.

1True widths of stratiform, laminated mineralization, and semi-massive mineralization are estimated to be

with an undetermined true thickness.

Notes on sampling, assaying, and data aggregation:
The diamond drill core logging and sampling program was carried out under a rigorous quality assurance /
quality control program using industry best practices. Drill intersections in this release are all HQ3 (split
tube) size core (61.1mm / 2.4-inch diameter) with recoveries typically above 85% unless otherwise noted
in the table of results . After drilling, core was logged for geology, st ructure, and geotechnical
characteristics, then marked for sampling and photographed on site. The cores for analyses were marked
for sampling based on geological intervals with individual samples 1.5 m or less in length. Drill core was
cut lengthwise in half with a core saw; half-core was sent for assays reported in this news release, and the
other half is stored on site for reference. Bulk density was determined on site for the entire length of each
sample assayed by measurement of mass in air and mass in water. Sample duplicate bulk density
determinations and in-house bulk density standard determinations were each made at a rate of 5%. Since
2017, four in-house bulk density standards (mineralized drill core from the Tom deposit that span a range
of densities) have been used and show an acceptable long -term precision. Certified standard masses are
used to calibrate the scale balance used for bulk density determinations.
A total of 5% assay standards or blanks and 5% core duplicates are included in the sam ple stream as a
quality control measure and are reviewed after analyses are received. Standards and blanks in 2021 drill
results to date have been approved as acceptable. Duplicate data add to the long-term estimates of precision
for assay data on the proj ect and precision for drill results reported is deemed to be within acceptable
levels. Samples were sent to the Bureau Veritas preparation laboratory in Whitehorse, Yukon, where the
samples were crushed and a 500 g split was sent to the Bureau Veritas labo ratory in Vancouver, B.C to
be pulverized to 85% passing 200 mesh size pulps. Clean crush material was passed through the crusher
and clean silica was pulverized between each sample. The pulps were analyzed by 1:1:1 Aqua Regia
digestion followed by Inducti vely Coupled Plasma Mass Spectrometry (ICP -ES/ICP-MS) multi-element
analyses (BV Code AQ270). All samples were also analyzed for multiple elements by lithium borate fusion
and X-ray fluorescence analysis (XRF) finish (BV Code LF725). Over-limit Pb (>25.0%) and Zn (>24.0%)
were analyzed by lithium borate fusion with XRF finish (BV Code LF726). Silver and copper are reported
in this news release by method AQ270, and zinc and lead are reported by LF725 or LF726. Bureau Veritas
(Vancouver) is an independent, international ISO/IEC 17025:2005 accredited laboratory.

Results in this news release are length and bulk -density weighted averages as would be used in a Mineral
Resource estimate. Readers are cautioned that in Fireweed news releases prior to 2020 , only length
weighted assay averages were reported which may result in slightly lower (under -reported) average
values. Length and bulk-density weighted averages have been reported as these most accurately represent
the average metal-content of the intersections.
