FSE: M0G

Fireweed Intersects 15.12 m of 10.39% Zinc, 18.10 % Lead, and 296.9 g/t Silver,

Including 8.15 m of 12.76% Zinc, 22.44% Lead, and 361.4 g/t Silver, at Tom South

Step-Out Drill Hole

Vancouver, British Columbia: Fireweed Metals Corp. (“Fireweed” or the “Company”) (TSXV:

FWZ; OTCQX: FWEDF) is pleased to report the results of six drill holes from Tom South and two

drill holes from Jason Main as part of the 2024 drill campaign at its Macpass Project, Yukon,

Canada.

Highlights

• Hole TS24-002 from 595.52 metres (“m”) downhole: 15.12 m (10 m true width) of

10.39% zinc (“Zn”), 18.10% lead (“Pb”), and 296.9 g/t silver (“Ag”), including 8.15 m (5.4

m true width) of 12.76% Zn, 22.44% Pb, and 361.4 g/t Ag in nearest to surface intercept

at Tom South to date , demonstrating an increase in grade and thickness up- plunge of

previous Tom South intercepts.

• Hole TS24-001 from 732.56 m downhole: 18.15 m (11 m true width) of 9.02% Zn, 7.46%

Pb, and 148.3 g/t Ag, including 8.32 m (5.0 m true width) of 16.18% Zn, 13.52% Pb, and

278.8 g/t Ag.

• Hole JS24-002 from 326 m downhole: 28.02 m (8.3 m true width) of 7.10% Zn, 1.41%

Pb, and 5.6 g/t Ag, including 12.90 m (3.8 m true width) of 11.30% Zn, 2.74% Pb, and 10.3

g/t Ag.

• Significant concentrations of germanium and gallium associated with sphalerite

mineralization (included within the full results in Table 1).

CEO Statement

Peter Hemstead, President and CEO, stated, “The consistent high-grade intercepts at Tom South

reinforce that the feeder zone in this area continues to define Tom as one of the most prolific

known concentrations of zinc, lead, and silver in the Macpass District, with spectacular grades

representing intersections comprised almost entirely of sphalerite and galena. TS24-002

represents the nearest-to-surface and highest-grade intercept at Tom South to date, with a broad

distance of 200 metres remaining open for testing the up -dip projection of this high- grade

2

mineralized panel towards previous historical drilling. The feeder style mineralization intersected

at Tom South is one of several localized zones at Tom that have very high silver grades, further

enhancing the overall commodity mix of this deposit.”

Summary

The drill holes in this release comprise intervals of stratiform to massive zinc, lead, silver sulphide

mineralization (in the form of sphalerite and galena) from Tom South and Jason Main. At Tom

South, this zone of mineralization was first defined in 2023 following up on an isolated historical

intercept from 1990 and is interpreted as a continuous panel of high-grade zinc, lead, and silver

mineralization representing a feeder zone. The intercepts in this release comprise step-outs from

both the 1990 and 2023 intersections and continue to support the expansion of the mineralized

domain both up and down dip. Hole TS24-002 reveals a significant increase in grade up-dip, with

grades twice as high compared to those modeled for this zone in the 2024 Mineral Resource

Estimate (“MRE”)1. The implications of this intercept are three-fold:

- Potential to upgrade Inferred material to the Indicated category;

- Substantially enhances resource grades within this zone; and,

- Extends the projection of mineralization f arther up -dip, highlighting the opportunity for

meaningful resource growth.

This nearest to surface intercept at Tom South, located approximately 145 m in elevation below

the historical exploration workings at Tom West, demonstrates the practicality of accessing this

mineralization within an underground mining environment. At Jason Main, the intercept represents

a significant step out down dip from previous drilling, establishing continuity beyond the currently

reported resource.

Results

Drill holes from Tom in this release are located in the southern portion of the Tom deposit near

the hinge of a moderately plunging anticline. All five holes completed intersected laminated to

massive sulphides consisting of sphalerite, galena, and barite. The high ratios of lead to zinc

(>1:1) in TS24- 001D4 and TS24- 002 likely represent higher temperature hydrothermal fluids

related to formation of mineralization, and therefore an increase in proximity to the heart of a

conceptual feeder structure, with TS24- 002 representing the nearest -to-surface and highest -

grade intercept at Tom South to date. A significant distance of approximately 200 m remains open

for testing up-dip of TS24-002 toward previous drilling. The broad, high-grade intercept in TS24-

001 (photo 1) illustrates that mineralization remains consistent along strike to the west from

intercepts in 2023.

One hole was drilled to completion at Jason Main (JS24- 002); and one hole abandoned due to

ground conditions at Jason South (JS24 -001). The intercept at Jason Main is a 143 m step out

down dip of previous drill hole JS17-005 and approximately 25 m down dip from the margin of the

defined Inferred resource. This intercept shows good continuity in both width and grade with the

intersections currently defining the resource at Jason Main.

Summaries of the intercepts from these holes discussed above are as follows:

• Hole TS24-002 Intersected 15.12 m (estimated true width of 10 m) of stratiform to massive

sulphide grading 10.39% Zn, 18.10% Pb , and 296.9 g/t Ag , including 8.15 m (estimated

true width 5.4 m) of 12.76% Zn, 22.44% Pb, and 361.4 g/t Ag.

This intercept represents the farthest up-dip intercept tested at Tom South and defines a

235 m continuous panel of mineralization betweenTS23- 001D3 and TS24-002 within

3

contemporary (2017–2024) drilling and 275 m in length down dip to TS90-012. This panel

remains open both up and down dip.

• Hole TS24-001 a step-out inter section of 18.15 m (estimated true width of 11 m) of

stratiform to massive sulphide grading 9.02% Zn, 7.46% Pb, and 148.3 g/t Ag, including

8.32 m (estimated true width of 5.0 m) grading 16.18% Zn, 13.52% Pb, and 278.8 g/t Ag,

and including 3.57 m (estimate true width of 2.2 m) grading 21.96% Zn , 23.67% Pb, and

518.6 g/t Ag.

• Hole TS24-001D4 intersected 6.20 m (estimated true width of 4.3 m) of stratiform to

massive sulphide grading 12.51% Zn, 12.06% Pb, and 191.1 g/t Ag, including 4.65 m

(estimated true width of 3.2 m) grading 14.83% Zn, 14.29% Pb, and 224.4 g/t Ag.

• Hole TS24-001D1 intersected 4.93 m (estimated true width of 3.2 m) of stratiform to

massive sulphide grading 12.11% Zn, 6.72% Pb, and 144.5 g/t Ag, including 3.65 m

(estimated true width of 2.4 m) grading 15.48% Zn, 8.71% Pb, and 183.6 g/t Ag.

• Hole TS24-001D3 intersected 2.58 m (estimated as true width ) of stratiform to massive

sulphide grading 8.58% Zn, 9.61% Pb, and 80.6 g/t Ag.

• Hole JS24-002 intersected 28.02 m (estimated true width of 8.3 m) of stratiform to semi-

massive sulphide grading 7.10% Zn, 1.41% Pb, and 5.6 g/t Ag, including 12.90 m

(estimated true width of 3.8 m) grading 11.3% Zn, 2.74% Pb, and 10.3 g/t Ag.

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 NQ2 size (50.5

mm/ 1.99-inch diameter), with recoveries typically above 85% unless otherwise noted in the results tables.

After drilling, core was cleaned, logged for geology, structure, and geotechnical characteristics, then

marked for sampling and photographed on site. Certain cores were selected for core scanni ng using light

detection and ranging (LiDAR), short-wave infrared (SWIR), X-ray fluorescence (XRF), and high resolution

RGB image capture. The cores for analyses were marked for sampling based on geological intervals with

individual samples two metres or less in length, with one metre samples within mineralized zones. 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 assay sample 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 2024 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 (BV) preparation laboratory in Whitehorse,

Yukon, where the samples were crushed and a 500 g split was sent to the BV 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 lead (>25.0%) and zinc (>24.0%)

were analyzed by lithium borate fusion with XRF finish (BV Code LF726). For BV samples, 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 17025:2017 accredited laboratory.

Assay values may appear rounded to one decimal place but are given in full in Table 1, and Cross Sections

where zinc and lead grades are reported to two decimal places.

Results in this news release are length and bulk-density weighted averages as would be used in a Mineral

Resource estimate. Length and bulk -density weighted averages have been reported as these most

accurately represent the average metal-content of the intersections.

True widths for primary intervals are estimated by measuring perpendicular to strike within the short axis of

a stratiform wireframe that has been constructed in 3D around the mineralized intercepts at Tom South

based on assay results, geological logging, stratigraphic correlation, and bedding measurements from

oriented core. The massive sulphide mineralization and laminated mineralization at Tom are stratiform

(oriented parallel to bedding), therefore the true width, or thickness, of the zone is estimated perpendicular

5

to both the strike and dip direction of bedding. True widths are rounded to the nearest metre for widths over

10 m and to the nearest 0.1 m for widths less than 10 m, as this better reflects the precision of the estimates.

True widths should be regarded as approximate as these are derived from an estimation that uses a

preliminary interpretation of the geological model. True widths for nested intervals (marked as “Including”

in results tables) are estimated using a ratio of included to primary intersected widths to attribute appropriate

portions of the true width of the primary interval to the nested intervals.
