Fireweed Exploration Update: Significant Mineralization Discovered at New Target West

of Boundary Zone

Vancouver, British Columbia: FIREWEED ZINC LTD. (“Fireweed” or the “Company”) (TSXV: FWZ)

is pleased to announce that significant widths of near-surface zinc-lead mineralization have been discovered

at a new target west of Boundary Zone. S ix core holes have been drilled at Boundary Zone and area, and

six RC holes have been drilled at Tom. All three rigs remain drilling on the property.

Highlights

• Wide zones of mineralization have been discovered at a new gravity target located 360 m west of

prior Boundary Zone drilling

• Wide zones of mineralization have been encountered on infill and step-out holes at Boundary Zone

• 1,500 m of core drilling and 300 m of RC drilling have been completed to date

• Drilling continues at Boundary Zone, Boundary West, and Tom

CEO Statement

Brandon Macdonald, CEO, stated “We are very pleased to see early indications that Boundary Zone style

mineralization could be far more extensive than originally thought. Whether this new zone discovered is an

extension of Boundary Zone, a fault offset, or a new zone, we don’t know yet. Further drilling will tell.

Being able to move so quickly from a gravity survey to drilling the resulting anomaly really highlights the

agility and ability of our technical team. With mineralization demonstrated west of Bound ary, we now

eagerly await assay results.”

Core Drilling

Two drill holes, NB20-004 and NB20-007, have intersected significant widths of pyrite -sphalerite-galena

mineralization approximately 360 m to the west of Boundary Zone . The holes were drilled within the

previously untested gravity high anomaly that was defined earlier this summer . Mineral identification in

logging has been corroborated by portable XRF (X-Ray Fluorescence) results but no estimates o f grade

have been made. Drilling continues in this area.

Infill and step -out drilling at the heart of Boundary Zone has successfully encountered wide zones of

mineralization, significantly extending the known footprint of the mineralized zone and confirming

consistent mineralization in holes of different orientations.

Fireweed also plans to drill the 240 Mile Target later this season, marked by a large gravity anomaly that

may indicate buried mineralization between the Tom and Jason deposits (see Fireweed news release dated

June 11, 2020 for details of other targets).

Assays pending for all holes.

RC Drilling

Three infill holes in Tom West have been successfully drilled, demonstrating the potential to use RC drilling

as a low-cost alternative to diamond drilling for upgrading resource categories at shallow depths. Further

infill and twin holes are planned at the Jason Main deposit.

Qualified Person Statement

Exploration and a ‘Qualified Person’ as defined under Canadian National Instrument 43-101.

About Fireweed Zinc Ltd. (TSXV : FWZ): Fireweed Zinc is a public mineral exploration company

focused on zinc and managed by a veteran team of mining industry professionals. The Company is

advancing its district-scale 544 km2 Macmillan Pass Project in Yukon, Canada, which is host to the 100%

owned Tom and Jason zinc-lead-silver deposits with current Mineral Resources and a PEA economic study

(see Fireweed news releases dated January 10, 2018, and May 23, 2018, respectively, and reports filed on

www.sedar.com for details) as well as the Boundary Zone, Tom North Zone and End Zone which have

significant zinc-lead-silver mineralization drilled but not yet classified as mineral resources. The project

also includes large blocks of adjacent claims (MAC, MC, MP, Jerry, BR, and NS) which cover exploration

targets in the district where previous and recent work identified zinc, lead and silver prospects, and

geophysical and geochemical anomalies in prospective host geology.
