Fireweed Announces New Discovery at the Popcorn Target

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

(TSXV: FWZ; OTCQX: FWEDF; FSE: M0G) is pleased to report it has discovered mineralization

at Popcorn, a new target at the Macpass Project, Yukon, Canada.

Highlights

• Significant intercepts at Popcorn of near-surface vein and replacement style

mineralization, similar in character to Boundary Zone including:

o NB24-004 From 10. 83 metre (“m”) downhole: 46.03 m at 4.88 % zinc and 3.6

grams per tonne (“g/t”) silver, including 24.96 m at 8.27% zinc and 5.3 g/t silver

o NB24-002 From 15.75 m downhole: 54.75 m at 3.98% zinc and 3.9 g/t silver,

including 8.85 m at 6.13% zinc and 4.4 g/t silver, and also including 19.78 m at

6.71% zinc and 5.9 g/t silver

• Mineralization intersected across all seven holes drilled at Popcorn

• Located 600 m Northeast from Boundary Zone resource pit-shell, outside of the current

Mineral Resource Estimate2

CEO Statement

Peter Hemstead, Interim President and CEO , stated, “Popcorn represents the first exploration

success stemming from our regional exploration program this year at Macpass. Identifying near-

surface zinc mineralization and defining its continuity less than a kilometre from the pit-shell that

constrains the resource at Boundary Zone is significant in establishing Popcorn as an exciting

exploration opportunit y. In addition to being open in all directions , t here is also potential for

massive sulphides, similar to the feeder style mineralization seen at Boundary Zone, that we

intend to explore in the future.”

Summary

The seven drill holes in this release (full results available in table 1 at the end of this release)

comprise 1476 m of drilling with intervals of vein and replacement style mineralization at the new

Popcorn target, 600 m northeast of the open pit -shell that constrains the resource at Boundary

Zone. These holes were targeted around zinc surface mineralization in trenches and an isolated

intercept from 1982. The 2024 drilling confirms the presence of mineralization near -surface as

well as establishes its continuity over a strike length of 200 m, open both along strike and at depth.

The mineralization discovered at Popcorn defines a new zone that is not included within

Fireweed’s current Mineral Resource Estimate2. The style of mineralization in these drill holes is

similar to the vein and replacement intervals throughout Boundary Zone which occur around the

massive to semi-massive sulphides of the Upper Zone (“BZUZ”) and Prime Zone (“BZPZ”).

Results

All drilling at Popcorn in 2024 was successful in intersecting vein and replacement style sulphides

comprising sphalerite and minor galena. The style of mineralization indicates these sulphides are

potentially part of the same later phase style of mineralization at Boundary Zone overprinting the

massive sulphides. The drilling establishes continuity of mineralization at this target in the near -

surface and remains open in all directions.

Fireweed successfully intersected vein and replacement sulphides (Photos 1 and 2) in all holes

at Popcorn. Summaries of the intercepts from these holes are as follows:

• Hole NB24-004 intersected 46.03 m of vein and replacement style mineralization grading

4.88% zinc and 3.6 g/t silver, including 14.13 m grading 8.27% zinc and 5.3 g/t silver and

including 5.36 m grading 13.01% zinc and 6.5 g/t silver.

• Hole NB24-002 intersected 54.75 m of vein and replacement style mineralization grading

3.98% zinc and 3.9 g/t silver including 8.85 m grading 6.13% zinc and 4.4 g/t silver, also

including 19.78 m grading 6.71% zinc and 5.9 g/t silver and including 7.01 m grading

11.20% zinc and 9.0 g/t silver

• Hole NB24-007 intersected 24.05 m of vein and replacement style mineralization grading

4.80% zinc and 6.3 g/t silver

• Hole NB24-005 intersected 21.77 m of vein and replacement style mineralization grading

3.60% zinc and 3.2 g/t silver, and also intersected 53.95 m grading 3.70% zinc and 3.8 g/t

silver, including 11.54 m grading 8.69% zinc and 5.1 g/t silver and including 5.80 m grading

11.29% zinc and 6.4 g/t silver

• Hole NB24 -012 intersected 20.25 m of vein and replacement mineralization grading

3.78% zinc and 3.3 g/t silver, including 2.45 m grading 14.47% zinc and 8.0 g/t silver

• Hole NB24-003 intersected 6.16 m grading 7.64% zinc and 4.0 g/t silver, including 2.93 m

grading 12.30% zinc and 4.7 g/t silver, and also intersected 4.94 m grading 5.32% zinc

and 5.7 g/t silver

• Hole NB24-009 intersected a one metre interval of vein mineralization grading 2.99% zinc

and 2.6 g/t silver

Holes NB24-002, NB24-003, NB24- 004, NB24-005, NB24- 007, NB24-009 and NB24- 012 are

exploration holes that followed up on an isolated intercept from 1982 and discovered vein and

breccia mineralization within conglomerates and mudstones . These mineralized zones are

interpreted to be the same stratigraphy as the lithologies present at Boundary Zone which overlie

the massive and stratiform sulphides of the BZUZ and BZPZ. Collectively these mineralized

intervals comprise the new zone called Popcorn , with intercepts forming a continuous zone of

mineralization with an irregular internal geometry of veins and replaceme nt zones consisting of

pyrite, sphalerite, and barite. The zone is broadest and highest grade near surface.

Similar looking vein and breccia mineralization at Boundary Zone occurs both stratigraphically

above and below the high-grade stratiform laminated massive sulphide zones. This mineralization

forms within a halo on both sides of the stratiform laminated zones at Boundary Zone and is

interpreted as a stockwork of randomly oriented veins and breccia zones that are contained within

broadly stratiform bodies.

Data Verification and QA/QC

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 and HQ

size core (50.5 mm/ 1.99- inch diameter, 63.5 mm/ 2.5- inch) 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 scanning. The cores for analyses were marked for sampling based on geological intervals

with individual samples 2 m or less in length, with 1 m samples within mineralized zones. Drill core was cut

lengthwise in half with a core s aw; 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 dupl icate 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,

5

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 sa mple. 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, Table 2, and Cross

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

Results in this news release are selected from composites with selection parameters based on a 1.41%

zinc equivalent cut off (ZnEq*) with elemental abundances within the composite presented 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. ZnEq is not reported and is used solely as a composite selection criterion.

Vein and breccia mineralization at Boundary Zone are interpreted to be stockworks with variable shapes

and true widths cannot be accurately estimated, therefore only intersected widths are reported, and true

widths are marked as N/A in the assay tables. 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 estimatio n 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.

This news release also contains references to estimates of mineral resources. The estimation of mineral

resources is inherently uncertain and involves subjective judgments about many relevant factors. Mineral

resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any

such estimates is a function of the quantity and quality of available data, and of the assumptions made and

judgments used in engineering and geological interpretation, which may prove to be unreliable and depend,

to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove

to be inaccurate. Mineral resource estimates may require re- estimation based on, among other things: (i)

fluctuations in the pri ce of zinc and other metals; (ii) results of drilling; (iii) results of metallurgical testing,

process and other studies; (iv) changes to proposed mine plans; (v) the evaluation of mine plans

subsequent to the date of any estimates; and (vi) the possible failure to receive required permits, approvals

and licenses.
