CEO Statement

Brandon Macdonald, CEO, stated “ The 2022 Boundary Zone drill results are nothing short of

spectacular. Earlier in the season at Boundary West we drilled the best hole in 72 years of

exploration anywhere at the Macmillan Pass project. The current results are not far behind and

include extremely high-grade intersections within a new stratiform zone that we have now

intersected in just a few holes at Boundary Main. With our biggest ever drill program planned for

2023, we see great potential for Boundary Zone.”

*Intersected thicknesses, not true thicknesses, are stated for all intersections in Table 1. Due to the early-

stage of drilling, true thicknesses cannot be accurately stated for these holes . Numbers in the text may

differ slightly from the table due to rounding.

NB22-012, NB22-022 and NB22-023

These hole s intersected wide zones of high- grade zinc mineralization on both sides of the

Boundary Main Fault (see Cross Section H -H' and Map 2), including many near surface

intersections. Above the fault are zones of vein-hosted sphalerite, including very -high grade

breccias. Below the fault, NB22-022 and NB22-023 intersected the new stratiform zone,

previously reported in NB22-018 and NB22-020 (see Fireweed news release dated February 27th

2023). In NB22-022 and NB22-023 the new zone is very high grade, including significant lead and

silver mineralization in addition to the high-grade zinc.

Hole NB22-023 intersected 298 m of 4.5% zinc, 1.4% lead, and 30.9 g/t silver including a 36.9 m

intersection of 15.1% zinc, 5.2% lead, and 127.6 g/t silver that included very high grade breccia

and veins over 4.4 m grading 38.3% zinc and 103.1 g/t silver and a very high grade new stratiform

3

zone of massive sulphide over 9.6 m grading 24.5% zinc, 15.1% lead, and 323.2 g/t silver (Tables

1 and 2). Included near the end of the 298 m interval is a 27.1 m intersection of 7.3% zinc, 5.6%

lead, and 77.2 g/t silver of massive sulphide and vein mineralization hosted in volcaniclastic rocks.

NB22-022 intersected 227 m of 5.7% zinc, 0.6% lead, and 21.6 g/t silver including some high

grade intervals of sphalerite vein and breccia mineralization above the Boundary Main Fault: 15.8

m of 14.5% zinc , and 27.1 g/t silver; 1.4 m of 32.8% zinc, and 29.7 g/t silver; 10.1 m of 17.0%

zinc, and 40.3 g/t silver; and 3.5 m of 10.6% zinc, and 17.2 g/t silver (Tables 1 and 2). In the new

zone of stratiform massive sulphide mineralization, a 9.3 m intersection graded 16.6% zinc, 4.4%

lead, and 143.1 g/t silver (see Image 1). Near the base of the 227 m intersection was a sub-

interval of 26.4 m that graded 10.9% zinc, 1.1% lead, and 26.9 g/t silver within silicified diamictites.

NB22-012 intersected a wide interval of sphalerite vein mineralization largely in the hangingwall

of the Boundary Main Fault of 174.7 m of 3.0% zinc, and 7.9 g/t silver, including: 32 m of 6.4%

zinc, and 11.2 g/t silver; 6.9 m of 5.2% zinc, and 5.1 g/t silver; and 10.1 m of 8.3% zinc, and 34.1

g/t silver.

NB22-017 and NB22-015

These two infill holes were drilled from the same pad to test high grade vein and breccia

mineralization in the hangingwall of the Boundary Main Fault. Hole NB22-017 intersected 60.5 m

of 12.0% zinc, 0.4% lead, and 21.9 g/t silver including a 20.4 m intersection of 25.8% zinc, 1.0%

lead, and 46.4 g/t silver that contained an interval of 6.2 m of 40.1% zinc, 0.3% lead, and 84.2 g/t

silver, demonstrating that this high-grade zinc mineralization is present in the near surface (see

Image 2 and Tables 1 and 2). Hole NB22-015 intersected 14 m of 6.8% zinc, and 10.0 g/t silver

including 2.4 m of 19.7% zinc, and 29.3 g/t silver within 30 m of surface.

Geological interpretation

Dr. Jack Milton, Chief Geologist, Fireweed Metals, remarked “Boundary West and Boundary Main

are separated by a 300 m gap in the drilling at depth. To vector in on high grade feeder zones,

we map out in 3D, increases in: lead mineralization; silicification of the host rocks; abundance of

diamictite rocks; and geochemically anomalous indicators such as copper concentration. At

Boundary we see all of these factors increase towards the gap in the drilling from both sides and

this occurs across an early -formed syn-sedimentary fault that likely served as a conduit for

mineralizing fluids – a potential feeder zone. On one side of this gap at Boundary West we have

our best ever hole and on the other side we have these very high-grade results from the newly

discovered stratiform zone that is in the same position in the stratigraphy as our Tom and Jason

deposits. We see great potential for even higher grades and more metal in the feeder zone, and

we are very excited to test this gap by drilling as part of our large 2023 exploration program.”.

See Long Section I-I’ for a summary of the Boundary Zone mineralization and an interpretation of

the target of a potential feeder zone.

About Fireweed Metals Corp. (TSXV: FWZ; OTCQB: FWEDF; FSE:20F): Fireweed Metals is a

public mineral exploration company on the leading edge of Critical Minerals project development.

Fireweed is well-funded, with a current cash position of approximately C$38,000,000 and is well-

positioned to carry out a large 2023 exploration program. The Company has three projects located

in Canada:

• Macmillan Pass Zinc-Lead-Silver Project: Fireweed owns 100% of the district-scale

940 km2 Macmillan Pass project in Yukon, Canada, which is host to one of the largest

undeveloped zinc resources in the world* where the Tom and Jason zinc -lead-silver

deposits have current Mineral Resources and a PEA economic study (see Fireweed news

releases dated 10th January 2018, and 23 rd May 2018, respectively, and reports filed on

www.sedar.com for details). In addition, Boundary Zone (comprising Boundary Main, and

Boundary West), Tom North (located adjacent to the Tom deposit) and End Zone 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 upside exploration potential. The large 2022 drill program utilizing four drills is

complete and assay results are being announced as they are received and interpreted.

• Mactung Tungsten Project: The Company has signed a definitive Asset Purchase

Agreement and acquired 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 resources in the world of the Critical

Mineral tungsten*. Located in Canada, it is one of the rare large tungsten resources

outside of China. An updated mineral resource is planned for Q2 2023, and re-sampling

of historic drill core is continuing and will include assays for previously unreported by -

product metals, such as gold, copper, and bismuth, in addition to tungsten.

• Gayna River Zinc-Lead-Gallium -Germanium Project: Fireweed has 100% of the

128.75 km 2 Gayna River project located 180 kilometres north of the Macmillan Pass

project. It is host to extensive mineralization including Critical Minerals zinc, gallium and

germanium as well as lead and silver, outlined by 28,000 metres of historic drilling and

significant upside potential. The results from the 2022 field program of geochemical

sampling, airborne LiDAR topographic surveying and ground geophysics are now being

interpreted towards defining drill targets.

Data verification

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 HQ3 (split tube)

size core (61.1 mm / 2.406 inch diameter) or NQ2 size core (50.5 mm/ 1.99-inch diameter) with recoveries

typically above 85% unless otherwise noted in the table of results. After drilling, core was cleaned, scanned

with a core scanning machine, logged for geology, structure, 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 2 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 st andard 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 standar d 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 sample stream as a

quality control measure and are reviewed after analyses are receiv ed. Standards and blanks in 2022 drill

results to date have been approved as acceptable. Duplicate data add to the long- term estimates of

precision for assay data on the project 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 laboratory 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 Inductively 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 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.

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.
