Fireweed Drills 56.5 m of 6.34% Zinc and 36.4 g/t Silver Including 11.6 m of 10.9%

Zinc and 43.5 g/t Silver

Vancouver, British Columbia: FIREWEED METALS CORP. (“Fireweed” or the “Company”)

(TSXV: FWZ; OTCQB: FWEDF, formerly Fireweed Zinc Ltd.) is pleased to announce additional

results from the 2022 drill program at Boundary West, Macmillan Pass, Yukon, Canada (Map 1).

Highlights

• An infill hole intersected 56.5 m of 6.34% zinc, 0.38% lead, and 36.4 g/t silver within the

massive sulphide zone at Boundary West.

• Several step-out holes successful ly intersected stratiform mineralization, massive

sulphides and Howard Pass style mineralization, extending the mineralization at Boundary

West.

• Assay results from 21 holes from Boundary Main and Tom are pending from the 2022 drill

program.

• Fireweed is preparing for its largest ever drill program with a cash position of C$38.6M.

CEO Statement

Brandon Macdonald, CEO, stated “These results from the 2022 Boundary West drilling program

include several significant step-outs and demonstrate that the massive sulphide zone carries good

grade and continuity . We hit another intersection in the Howard’s Pass style mineralization in

older rock units for which we see further potential across the property. Results are pending from

many of the 2022 drillholes that intersected wide intervals of intense sphalerite-galena

mineralization at Boundary Main and the Tom deposit.”

Boundary West Drilling Results

The following drill results are from three drill holes located at Boundary West (Maps 1 and 2). The

results from many other holes from the 2022 drill program are pending, including 12 holes from

Boundary Main, 8 holes from Tom West and 1 hole from Tom East.

At depth, this hole intersected a zone of stratiform zinc -lead-silver mineralization over 28 m

grading 2.6% zinc, 1.5% lead, and 26.5 g/t silver (Table 1, Cross Section D -D’). Preliminary

geological interpretations correlate this layer with the stratiform zinc -lead-silver mineralization

previously discovered at Boundary West, representing an approximately 115 m step-out. A thin

(0.65 m) intersection of high-grade sphalerite veining returned 28.5% zinc within a sequence of

conglomerates, similar in style to Boundary Main (Table 1). This hole was targeting a step-out

from the very high grade and wide intersection of massive sulphide in hole NB22-002 (reported

in Fireweed News Release dated Nov 22, 2022) but had to be abandoned short of the target due

to excessive drillhole deviation and the step-out target remains untested.

NB22-007

This hole intersected 4 m of semi-massive sulphide mineralization grading 5.2% zinc and 11 g/t

silver within silicified and siderite-altered lapilli tuffs (Table 1), representing a ~30 m step-out up-

dip from the newly discovered zone reported in NB22-002 (Fireweed news release dated Nov 22,

2022). This hole also intersected a zone of massive sulphide over 7.3 m grading 10.7% zinc, 1.7%

lead, and 75.1 g/t silver including 3.8 m of 15.5% zinc, 1.8% lead, and 94.9 g/t silver (Table 1 ,

Cross Section D-D’). The massive sulphides are hosted in a sequence of silicified black mudstone

and barite that ends abruptly against a fault and are interpreted as a faulted block, representing

an incomplete section through the Boundary West massive sulphides , stepping out ~35 m from

the same zone in NB21-001.

NB22-019

This hole provided an infill intersection of 56.5 m of 6.3% zinc, 0.4% lead, and 36.4 g/t silver within

the massive sulphide zone at Boundary West including two distinct high-grade zones: 11.6 m of

10.9% zinc, 0.3% lead, and 43.5 g/t silver ; and 13 m of 9.6% zinc, 0.7% lead and 48.2 g/t silver

(Table 1). This hole also provided a step-out of the Howard Pass style mineralization intersecting

15.6 m of 2.6% zinc including two 3.1 m intersections of 5.4% zinc and 4.6% zinc, respectively

(Table 1). This is a ~50 m step-out from similar mineralization in NB20-009 (see Fireweed news

release dated February 25, 2021).

Most zinc mineralization at Macmillan Pass is hosted in Devonian age rocks, however, in 2020,

Fireweed dr illed a hole that resulted in the discovery of zinc mineralization hosted in older

Ordovician-Silurian rocks and termed this “Howard’s Pass style” mineralization owing to similar

age host rocks at the large Howard’s Pass zinc-lead deposits that are located approximately 60

kilometers away from Boundary Zone. This was the first discovery of zinc mineralization in these

older rocks at Macmillan Pass. Note the Howard’s Pass deposits are not owned by Fireweed and

a comparison of these similar geological settings is for information purposes only and does not

imply that similar potential quantities or grades will be delineated at Macmillan Pass . The

Howard’s Pass style mineralization at Macmillan Pass is at an early stage of exploration and

remains to be tested with additional drilling.

*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, but are estimated relative to

intersected thickness at 10-40% for NB22-004, and 50-75% for NB22-007 and NB22-019 based on angles

of bedding to core axis.

Note – an interval of core in NB22-007 from 100.72 m to 131.62 m was not assayed as these core intervals

were lost to a windstorm that up-ended several core tables, spilling the core on the ground prior to logging

and sampling.

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) 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 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 sample stream

as a quality control measure and are reviewed after analyses are received. 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 withi n 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

4

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 l ower

(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.
