NEWS RELEASE
August 20, 2019 TSXV: FWZ
Fireweed Drills New Zone at the Macmillan Pass Project
Including 22.5 metres of 6.13% Zinc and 0.95% Lead
Vancouver, British Columbia: FIREWEED ZINC LTD. (“Fireweed” or the “Company”) (TSXV: FWZ)
is pleased to announce assays from the first five drill holes in the Tom North open pit target and a step out
hole at Tom West at the Macmillan Pass Project in Yukon, Canada. Drilling has now finished on the
property and additional assays from multiple zones are pending.
Highlights
• Tom North hole TS19-002 intersected 6.36% Zinc and 0.65% Lead over 9.00 metres and
TS19-001 intersected 6.19% Z inc and 0.51% Lead over 7.30 metres (true width s), successfully
proving the concept of the near -surface Tom North exploration target that has potential to be
mined in an open-pit and improve current PEA economics.
• Tom North hole TS19 -006 intersected 6.13% Zinc and 0.95% Lead over a wide interval of
22.54 metres (true width) , significantly improving on historic grades and widths as a result of
superior core recovery.
• The drill program has been successfully completed for a total of 2,35 7 metres drilled in 16
diamond drill holes. Assays from additional holes are pending.

CEO Statement
Brandon Macdonald, CEO, stated “We are pleased with the results from the first 2019 drill assays. So far
Tom North is showing potential open-pit results and i t is noteworthy that hole s TS19-005 and TS19-006
reported much higher grades over wider intervals than the 1952 hole they twinned due to better recoveries
using modern drilling techniques. With these positive first drill assays now in, we look forward to release
of drill results from other zones tested this summer to expand on our current resources, which are already
among the largest undeveloped zinc resources in the world, as well as the field program of geophysics,
geochemistry and mapping still ongoing.”

Tom North
Historic trenching and very shallow, low -recovery drilling in 1952 indicated the presence of near -surface
mineralization at Tom North. The first drill holes of the 2019 season have confirmed that mineralization
extends to depth, and the results define a near -surface zone of zinc-lead mineralization that is potentially
amenable to open-pit mining. The Tom North exploration target has mineralization demonstrated over a
strike length of at least 500 metres, a true thickness between 6 and 23 metres (average of 12 metres), with
the down-dip extent tested to 190 metres, and is open to depth (Figures 1-3). The average bulk density of
the mineralized rock is 2.86 t/m 3. The mineralization is stratiform and comprises laminated fine-grained
sphalerite-galena-pyrite-barite. Tom North is a distinct zone separated from the Tom West zone by
faulting (Figure 2).
No mineral resource has been estimated for Tom North and the zone is not included in the current mineral
resource estimate for the property (described in Fireweed news release dated January 10, 2018) . Tom
North represents potential for a significant expansion to the Tom minera l resources, to extend open pit
and underground mine life, and to improve project economics described in the current Preliminary
Economic Assessment (PEA) (see Fireweed news release dated May 23, 2018). The current PEA includes
a three year open-pit mine life at Tom West over the course of an overall 18 year mine life.
Drill hole s TS19-005 and TS19 -006 effectively twinned a historic 1952 drill hole and both returned
significantly higher grades and thicknesses than the historic twin hole, owing to better recover ies using
modern drilling methods. TS19-006 was drilled below TS19-005 to improve on core recoveries and
obtain a slightly deeper cut of the zone. Two additional twin holes have been drilled in Tom North, and
assays are pending.
Tom West
A step-out hole at Tom West , TS19-004, extends the mineralization to the south . Mineralization in the
hole was cut off by a fault, limiting the width of the drilled in tersection (Figure 2). Structural information
gathered from the hole will be used to inform further exploration in this area.
2019 Drilling
The 2019 drill program is now complete. A total of 16 diamond drill holes have been drilled for a total of
2,357 metres. Targets tested were Tom North, Tom East, Tom West, Jason North, Target A, Target G,
Target R, and Boundary Zone (Tables 2 & 3, and Figure 4). Assays are pending for all holes not included
in this release and summary descriptions of field results and observations are provided in Table 3.
Notes on sampling and assaying:
The drill core logging and sampling program is 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%. After drilling, core is logged
for geology, structure and geotechnical characteristics, marked for sampling, and photographed on site.
The cores for analyses are marked for sampling based on geological intervals with individual samples
1.5 metres or less in length. Drill core is cut lengthwise in half with a core saw; half-core is sent for assay,
the other half is stored on site for reference. A total of 5% assay standards and 5% blanks are inserted into
every sample shipment as a quality control measure and reviewed, after analyses are received. Standards
and blanks in shipments to date have been approved as acceptable. Samples are sent to the Bureau Veritas
(formerly Acme Labs) preparation laboratory in Whitehorse, Yukon, where the samples are crushed and a
500 g split is pulverized to 85% passing 200 mesh size pulps. Clean crush material is passed through the
crusher and clean silica is pul verized between each sample. The pulps are then sent to the Bureau Veritas
laboratory in Vancouver, B.C. and analyzed by 1:1:1 Aqua Regia digestion followed by Inductively
Coupled Plasma Mass Spectrometry (ICP -ES/ICP-MS) multi-element analyses (BV Code AQ2 70). All

samples are 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 is 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.
Technical information in this news release has been approved by Gilles Dessureau, P.Geo, Vice President
Exploration and a ‘Qualified Person’ as defined under Canadian National Instrument 43-101.
