Fireweed Announces Near-Term Plans for Mactung Project

• Initiating a Preliminary Economic Assessment (PEA) to validate Project economics and

evaluate opportunities to add value.

• Conducting metallurgical test program to validate and optimize tungsten recovery and

assess the recoveries of by-products gold and copper.

• An environmental and socioeconomic assessment for the Project was completed in 2014,

allowing for licensing processes to proceed.

• Planning additional environmental studies and field investigation programs in 2023 to

bolster understanding of key project components.

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

(TSXV: FWZ; OTCQB: FWEDF) is pleased to provide an update on the near -term plans for the

Mactung Project, following release of the Resource Estimate that establishes Mactung as the

world’s largest, high-grade tungsten deposit** (see news release dated June 13, 2023*).

CEO Statement

Brandon Macdonald, CEO, stated “ Fireweed’s recent Resource Statement on Mactung has

reaffirmed the project’s status as one of the world’s preeminent tungsten development stories .

Building on that resource our team now looks to advance the project to construction readiness

through modern metallurgical studies, value engineering, and by working with Indigenous groups

through the regulatory processes. This coming year will establish Mactung as not just a great

resource but also a credible near-term supplier for the critical mineral tungsten.”

Preliminary Economic Assessment

The upcoming Preliminary Economic Assessment (PEA) will establish preliminary project

economics using current pricing and cost data, modern estimation, metallurgical, and engineering

methodologies, and will consider other opportunities for project optimiza tion. The PEA will build

2

on work commissioned by North American Tungsten Corporation (NATC) in their 2009 Feasibility

Study. The new study is planned to kick-off this quarter and conclude prior to the end of the year.

Metallurgical Test Program

In 2022 and early 2023, Fireweed conducted a comprehensive resampling and re-assaying

program on historic drill core, which has provided a larger geochemical dataset to assist with

lithogeochemical domaining and achieving representative sample variability throughout the

deposit.

Fireweed recently initiated a metallurgical test program with Base Metallurgical Laboratories Ltd.

to confirm results from earlier work by previous owners (NATC), optimize the flowsheet and

evaluate the potential recoverability and payability of gold and copper. Preliminary tailings test

work will also be included in this work. Results from this program are expected in Q4 2023.

Assessment and Regulatory Processes

The Yukon Environmental and Socio-economic Assessment Board issued a positive screening

report for the Mactung Project in mid-2014 and recommended it proceed without review, subject

to terms and conditions. The federal and Yukon governments subsequently varied certain terms

and conditions, as documented in each respective Decision Document, which provided direction

to advance license applications.

Fireweed intends to complete field programs this summer at Mactung to strengthen the

environmental database and confirm distribution of discontinuous permafrost to validate

geochemical analysis of ore and waste, and to identify and qualify borrow material for

construction. The results of these programs will inform collaborative working groups discussions

with Indigenous groups to allow Fireweed to develop robust applications and management plans

to mitigate any potential effects arising from future potential project development.

Grant of Options

The Company announces that it is granting, pursuant to it’ s stock option plan, stock options

exercisable into 4,544,000 common shares in the Company to certain directors, officers,

employees, and consultants of the Company. The stock options are exercisable at C$1.01 per

share with a five-year term, and 20% will vest on each of the following six -month anniversary

dates of the grant, being fully vested after 30 months.

Qualified Person Statement

Technical information in this news release has been approved by Fireweed Metals Vice President,

Studies, Kelly Bateman, P.Geo. (BC), a ‘Qualified Person’ as defined under Canadian National

Instrument 43-101.

About Fireweed Metals Corp. (TSXV: FWZ; OTCQB: FWEDF; FSE:20F): Fireweed Metals is a

public mineral exploration company on the leading edge of Critical Minerals project development.

Fireweed is well-funded, with a current cash position of over C$30,000,000 and is well-positioned

to carry out the large 2023 exploration program. The Company has three projects located in

Canada:

• Macmillan Pass Project (Zinc-Lead-Silver): Fireweed owns 100% of the district-scale

940 km2 Macmillan Pass project in Yukon, Canada, which is host to one of the largest

3

undeveloped zinc resources in the world* where the Tom and Jason zinc -lead-silver

deposits have current Mineral Resources 1 (11.21 Mt Indicated Resource at 6.59% zinc,

2.48% lead, and 21.33 g/t silver; and 39.47 Mt Inferred Resource at 5.84% zinc, 3.14%

lead, and 38.15 g/t silver) and a Preliminary Economic Assessment 2 (PEA). In addition,

Boundary Main, Boundary West, Tom North and End Zone have significant zinc -lead-

silver mineralization drilled but not yet classified as mineral resources. The project also

includes large blocks of adjacent claims with known showings and significant upside

exploration potential.

• Mactung Project (Tungsten): The Company recently acquired 100% interest in the 37.6

km2 Mactung Project located adjacent to the Macmillan Pass Project. Recently announced

new mineral resources for Mactung (41.5 Mt Indicated Resource at 0.73% WO 3 and 12.2

Mt Inferred Resource at 0.59% WO 3)* make it one of the largest and highest- grade

undeveloped resources in the world of the Critical Mineral tungsten**. Located in Canada,

it is one of the rare large tungsten resources outside of China.

• Gayna River Project (Zinc-Lead-Gallium -Germanium): Fireweed has 100% of the

128.75 km2 Gayna River project located 180 km north of the Macmillan Pass project. It is

host to extensive mineralization including Critical Minerals zinc, gallium and germanium

as well as lead and silver, outlined by 28,000 m of historic drilling and significant upside

potential.
