FIREWEED DISCOVERS MORE ZINC MINERALIZATION AT MACMILLAN PASS,

AND COMPLETES 7,000 M DRILL PROGRAM

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

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

announce the completion of the 2022 drill program at their flagship Macmillan Pass zinc-

lead-silver project, located within the prolific Selwyn Basin zinc district of Yukon, Canada.

Highlights

• Fireweed has completed a 7, 000 m diamond drilling program at Macmillan Pass.

Assays for all holes are pending.

• Step-out drilling has successfully extended the area of known mineralization at

Boundary Zone.

• New discoveries of massive sulphide and laminated stratiform zinc mineralization at

Boundary Zone.

• Sphalerite veins and vein breccias intersected in multiple holes at Boundary Zone.

• Infill drilling around the high -grade feeder zone at the Tom deposit has achieved

significantly improved drilling recovery compared to nearby historic holes.

• 11,000 metres of core have successfully been scanned using state-of-the-art XRF and

hyperspectral sensors.

CEO Statement

Brandon Macdonald, CEO, stated “The 2022 drill program was not only our biggest, but it

was our best. Our drilling consistently yielded wide zones of zinc mineralization at Boundary

Zone, including many potentially very high-grade intervals and new discoveries. The infill

drilling at Tom has produced some spectacular massive sulphide intervals that we

anticipate will grade significantly higher than the grades of the surrounding blocks in the

current mineral resource model due to better recoveries achieved by modern drilling. Our

efficient drill program hit zinc mineralization in every hole, maximizing the value from this

2

year’s drilling and going a long way to demonstrate the large size potential of Boundary

Zone. Our new discoveries provide a compelling new addition to the Macmillan Pass project

alongside our Tom and Jason deposits.”.

Cautionary Statement

Fireweed has drilled many intersections in the 2022 program that contain visible sphalerite

and galena, sulphides of zinc and lead, respectively. The apparent abundance of these

minerals based on visual estimates made during core logging are considered material

results of drilling investigations and are being disclosed in this release in a timely way, in

consideration of anticipated delays from the commercial laboratories for final assay results.

Investors are cautioned that visual estimates of the abundance of sphalerite or galena are

preliminary qualitative geological interpretations of anticipated zinc and lead grades that

can only be confirmed once final assays are received. In an effort to not be misleading, and

to not conflate the material results of surveys and investigations regarding the property with

sample, analytical or testing results on the property, visual grade or mineral abundance

estimates have not been quantified but are stated as the relative terms “low”, “moderate”,

“high”, and “very high” in comparison to the average zinc and lead intersections within

mineralized zones at Boundary Zone and Tom in pre-2022 drilling.

Summary of material results from drilling investigations

Boundary Zone

Twenty-three diamond drill holes were collared at Boundary Zone including six holes at

Boundary West and seventeen holes at Boundary Main (Maps 1, and 2).

At Boundary West, several step-out holes have intersected wide zones of massive

sulphides, including a new zone of massive sulphides, leaving Boundary West open to the

south and at depth. A particularly wide (75 m) step-out intersection in hole NB22-002

comprised an apparent greater abundance of galena and sphalerite compared to other

massive sulphide intersections observed to date at Boundary West. The preliminary

geological interpretation is that this intersection is located close to the feeder structure, with

room to step out further towards the feeder to the east and at depth. Infill holes at Boundary

West continue to demonstrate the continuity of the massive sulphide zone first discovered

by Fireweed in 2020 (see Fireweed news release dated September 24th, 2020).

At Boundary Main, two significant new discoveries have been made. A new zone of massive

sulphide was intersected in three holes (NB22-018, NB22-022, NB22-023) with high to very

high visual abundances of sphalerite and galena. This zone was intersected between 70 and

120 m vertically below surface, and based on bedding orientations and intersected

thicknesses, it is interpreted to have a true thickness of approximately 7 to 10 m. Another

new zone of laminated sphalerite-galena mineralization was discovered in one hole (NB22-

008) at Boundary Main. This zone was intersected over 2.65 m with an undetermined true

thickness and comprised a high abundance of sphalerite and moderate abundance of

galena. Both of the new discoveries are stratiform, are open in multiple directions, and are

3

located in the same stratigraphy as the Tom and Jason deposits, showing good potential to

form extensive and continuous mineralized zones.

Boundary Main step-outs were longer holes (210 m to 370 m deep) drilled in multiple

directions to test beyond the previous extent of zinc mineralization defined by pre-2022 drill

holes, and successfully extended the mineralized zone. Vein-hosted and disseminated

sphalerite were encountered in wide zones, including short intervals of anticipated high

grades typical of this style of mineralization. Boundary Main remains open for extension in

all directions.

Infill drilling focused on closely spaced short holes that targeted near-surface high-grade

veins and vein-breccias to test the grade continuity of this mineralization style. Based on

high abundance of coarse-grained sphalerite observed visually, many of these infill holes

are anticipated to contain short high grade zinc intersections which can only be confirmed

once assays are received.

Tom Deposits

Eight infill holes were completed at Tom West, targeting feeder proximal mineralization to

test the validity of the current geological resource model and improve drilling recovery in

areas of historic poor drilling recovery (Map 3). All eight holes intersected the mineralized

zone close to where predicted by the geological model and had generally excellent core

recovery, much improved upon nearby historic drill holes. The intersections are anticipated

to have high to very high zinc and lead grades, potentially greater than grades in the block

model of the current Mineral Resource that were estimated using data from nearby historic

holes with low recovery (for details on the current Mineral Resource see Fireweed news

release dated January 10th 2018 and www.sedar.com for the technical reports filed February

23rd 2018 and July 9th 2018).

One infill hole was completed at Tom East to test the geological model, and the hole

confirmed the high sphalerite and galena abundances that are typical for this zone.

Collar details for all 2022 drill holes are provided in Table 2. Assays are pending for all holes

where samples have been submitted.

Core Scanning

Approximately 11,000 m of core have been scanned using a fully-integrated core scanning

system combining high-resolution digital photography, LiDAR topography, shortwave,

visible, and near infrared hyperspectral imagery, and X-ray fluorescence (XRF)

instrumentation. A combination of current and historic core has been scanned, and the

newly acquired data will be used to inform future development of geometallurgical models

of the deposits.

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. Drilling investigations

described in this release are either HQ3 (split tube) size core (61.1mm / 2.4-inch diameter) or NQ2

size core (50.5 mm) with recoveries typically above 85%. After drilling, core was scanned using

hyperspectral and high-resolution imaging, then logged for geology, structure, and

geotechnical characteristics, marked for sampling and photographed on site. Assays for all holes

are pending.

5

Comparison of visual estimates of sphalerite made during core logging in 2018 to 2021 were

compared to received zinc assays to verify the visual observations of sphalerite made in 2022, as

similar core logging practices were implemented in these years with consistency in supervisory

personnel. Fireweed’s 2018-2021 logging programs have consistently successfully identified

either the presence or absence of sphalerite in core, with very few false positives or false

negatives. However, the visual estimation of sphalerite abundance and zinc grade has varied

considerably among logging geologists compared to results from zinc assays.

Spot checks were made with a handheld X-Ray Fluorescence (XRF) instrument during core

logging to determine the presence of lead or zinc if there was doubt in the visual identification of

sphalerite or galena. Routine core scanning with an XRF sensor has further enabled the

verification of sphalerite and galena identification.
