Fireweed Drills Wide Step-Out Intersection of Massive Sulphides at Boundary

Zone and Starts Up Second Drill Rig

• A 73 m wide interval of massive sulphide zinc-lead mineralization has been intersected at

Boundary Zone and is open along-strike and at depth, validating the feeder zone target,

with plans for step-out holes in the interpreted direction towards the feeder.

• All three of the first drillholes at Boundary Zone have hit zinc-lead mineralization.

• Results indicate that the Boundary West and Boundary Main zones may be connected

parts of a single mineralized system.

• The second of five drill rigs is now at site and has started drilling at the Tom deposit.

• Drilling will target step-out holes at Tom, Jason, and Boundary Zone.

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

(TSXV: FWZ; OTCQB: FWEDF) is pleased to provide an update of its 2023 exploration program.

The first three drillholes have tested an area between the Boundary Main and Boundary West

zones and have intersected significant zinc-lead mineralization. The Company is c urrently

completing a 1,900 m Phase 1 drill program and plans to continue with an additional 14,000 m or

more of drilling across multiple step-outs and targets in 2023.

CEO Statement

Brandon Macdonald, CEO, stated “The season is off to a thrilling start, with a broad intersection

of massive sulphides in a step-out hole at Boundary Zone as part of the first test of our feeder

zone target. We are very excited that we hav e hit zinc -lead mineralization in all our first three

holes at Boundary Zone, stepping out from our discoveries in 2022. Progress has gone well on

the 2023 exploration campaign with the first rig making very good production and we have

capitalized on the relatively early snowmelt to mobilize a second rig ahead of schedule. The

imminent completion of our new 48-person, all-weather camp will facilitate exploration in 2023

and beyond.”

2023 Diamond Drill Program Update

The 2023 program will utilize five diamond drill -rigs, targeting over 16,000 m of drilling between

Boundary, Tom, and Jason zones (Map 1). Phase 1 of drilling is currently underway with >1,400

m completed of a planned 1,900 m . Phase 2 will comprise an additional ~14,000 m and both

phases focus on step-out holes around known zones of zinc-lead-silver mineralization.

Drilling Update

The initial phase of the 2023 drilling program targets a gap in the drilling between two of

Fireweed’s best-ever drillholes at Boundary Zone, NB22-002 and NB22-023, where Fireweed

sees the potential for a high-grade feeder zone target that could link Boundary West and Boundary

Main. These 2022 holes intersected very wide, high-grade zones and flank either side of the target

being tested in Phase 1: NB22-023 intersected 298 m of 4.5% zinc, 1.4% lead, and 30.9 g/t silver

including a new stratiform zone of 9.6 m grading 24.5% zinc, 15.1% lead, and 323.2 g/t silver ;

and hole NB22-002 intersected 124 m at 12.3% zinc , 1.3% lead, 45.9 g/t silver (see Fireweed

news releases dated November 22, 2022, and March 2, 2023).

The 2023 step-outs completed so far have successfully intersect ed sphalerite and galena

mineralization as stratiform massive sulphides, replacement mineralization, veins, and breccias .

Hole NB23-003 intersected 73 m of massive sulphide that is interpreted to be the first intersection

of the conceptual feeder zone target. The remaining holes of the Phase 1 program will continue

drill testing of the mineralized layers as well as the potential feeder area that may link Boundary

Main and Boundary West (Long Section I–I’, Cross Section H–H’, Cross Section J–J’ and Map 2).

Sphalerite and galena have been identified visually by experienced core logging geologists, and

licenced professional geoscientists . No absolute visual estimates of mineral abundances or

inferences of potential zinc or lead grades have been stated in this news release.

NB23-001

NB23-001 was drilled as a step-out from NB22-023 following up high-grade zinc intercepts in

stratiform, breccia, and vein hosted mineralization (e.g. NB22-023 hit 9.6 m at 24.5% zinc, 15.1%

lead, and 323.2 g/t silver, see Fireweed news release dated March 2, 2023). Hole NB23-001

successfully intersected sphalerite-galena mineralization over comparable widths, approximately

30 m down- dip, and in the same stratigraphic layer as the new stratiform zone intersected in

NB22-023 and NB22-022, providing a step-out and increasing confidence in the continuity of the

new stratiform zone at Boundary Main. The hole was extended 70 m past target depth due to

additional intersections of sphalerite veins and pyrite-sphalerite massive sulphide mineralization

downhole, and the hole was terminated at 460 m. See cross-section H–H’ for more details.

NB23-002

NB23-002 is the first hole drilled into the gap between Boundary Main and Boundary West ,

exploring the conceptual feeder zone target that may link the two zones. The hole intersected

mineralized conglomerate between 50 m to 65 m. Stratiform pyrite-sphalerite mineralization from

226 to 230 m abuts a fault and is interpreted as a fault-bounded sliver between the Boundary

Main fault and the Ramp fault. This stratiform mineralization is a n approximately 90 m step-out

along strike from high grade intersections in NB22-022 and NB22-023. This intersection provides

an additional vector towards the potential feeder zone.

NB23-003

Drilled down-dip from NB23-002 following the successful intersection of faulted stratiform

mineralization, NB23-003 intercepted mineralized conglomerate comp arable to NB23-002 from

61 to 68 m. A 73 m wide interval of massive stratiform sulphides containing pyrite, galena, and

sphalerite were intersected from 21 1 to 284 m . Intervals within this intercept contain a higher

visually-estimated abundance of galena than sphalerite, a characteristic that is thought to be

generally indicative of mineralization around or within a feeder zone. This broad intersection of

lead-rich massive sulphide provides an initial indication that the proposed feeder zone may link

the stratiform mineraliz ation at Boundary West and Boundary Main. The true thickness of this

wide intersection is not currently known due to the early -stage of the drilling. This massive

sulphide intersection is open along strike and at depth, towards the interpreted direction of a

potential feeder zone.

Drill Operations Update

Drill penetration rates in the initial three holes was more than 50% faster than historical

performance. The region experienced an early snowmelt this year, allowing a second rig to be

mobilized weeks earlier than planned, and coring commenced June 18th. Three additional drills

are being mobilized by truck this week, bringing the total to five rigs as planned. Drilling will target

significant step-outs at Tom, Jason, Boundary Zone and beyond.

Camp Expansion Update

Camp is operating smoothly with nearly 50 people on site. Construction is progressing well at the

new 48-person camp expansion, with commissioning and first occupants planned for month end.

Together with the existing camp, th e new all-weather camp will allow us to support around 100

people on site to complete the 2023 season objectives. This work is an important step to build out

Macmillan Pass camp capacity to the approved capacity of 150 people, allowing for both larger

drill programs and simultaneous environmental baseline studies and occupancy during colder

months.
