Fireweed Launches Largest Regional Exploration Campaign at Macpass

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

(TSXV: FWZ; OTCQX: FWEDF) is pleased to report the launch of the largest regional program at

Macpass aiming to unlock the 9 77 km2 district-level potential and develop new targets to

drill-ready state.

A 14,000+ metre drill program using four diamond drill rigs will have 8,000 m allocated to step out

holes at Tom, Jason, and Boundary, while 6,000 m will test new targets at Macpass as part of the

regional program.

Objectives of the 2024 program are drilling new discoveries from target-rich regional exploration,

and high-potential step out drilling from known zones at Macpass.

CEO Statement

Peter Hemstead, Interim CEO, stated “ We are excited to commence the largest regional

exploration program Macpass has ever seen. Comprising over 6,000 m etres of drilling at

greenfield targets, as well as comprehensive ground and airborne geophysical and geochemical

surveys, this regional work will aim to unlock over 40 kilometres of an under-explored prospective

trend at Macpass. As part of our growth strategy, we are also excited to be drilling step-out holes

at Tom, Jason and Boundary that will primarily focus on targets that may form extensions of the

major known zones.”

Adam Lundin Statement

Adam Lundin, Strategic Advisor to Fireweed, stated “Previous drilling at Tom, Jason and

Boundary Zone demonstrated the very large mineral endowment and future growth potential at

Macpass. However, we have only just scratched the surface in testing the true scale of this district

in the making. This summer’s exploration program is focused on growing the district’s mineralized

footprint through drilling many of the compelling greenfield targets for new discoveries, as well as

step-out targets at Tom, Jason and Boundary.”

Drill Program

The 2024 drill campaign at Macpass is planned to follow up on the success of the 2023 campaign

(see Figures) and will utilize four diamond drill rigs to test targets at Tom, Jason, Boundary, and

new regional generative targets. The first drill rig is anticipated to start turning by June 7 , 2024,

ramping up to four operating rigs by late June.

• Exploration: Exploration drilling is reserved to test new greenfield targets. Two currently

defined prospects Start Zone and Popcorn are drill ready, with the remaining metreage

designed to be allocated later in the season as new targets are defined through our

regional exploration efforts.

• Tom South: Drilling will target step-outs that lie outside of the current mineral resource

following up on successful intercepts of feeder-style mineralization from the 2023 program

(Photo 1).

• Jason: Drilling designed to follow up on the intersection in JS23-001D1 in Jason South.

• Boundary Zone: Drilling designed to step out from known mineralization at Boundary

Zone and to follow up on high-grade zones identified in 2023.

Regional Exploration

An expansive regional exploration program is planned for the 2024 field campaign at Macpass.

This program will utilize a combination of airborne and ground-based exploration techniques,

including a helicopter Versatile Time Domain Electromagnetic (VTEM) and magnetic survey, Light

Detection and Ranging (LiDAR) survey, ground -based gravity on both local and regional scale

grids, soil sampling, prospecting, and mapping. The program is designed to delineate and

advance current prospects, showings, and anomalies , as well as explore new targets in a

commodity agnostic manner. The primary focus of the regional exploration program is on new

sediment hosted zinc, lead, and silver targets; however, the program includes a number of targets

with the geological potential for reduced intrusion related gold systems (RIRGS).

Operational Update

Work has been completed on a new core-logging facility to streamline core logging process to

help facilitate the efficient flow of core and data. As part of the new build, historical core has been

relocated from Tom Camp to the adjacent facility at Sekie, Fireweed’s new 50-person, sub-alpine

camp designed to be operable during winter conditions. Upgrades were also completed at the

original Tom Camp to support continued summer habitation over the coming years.
