CEO Statement

Brandon Macdonald, CEO stated "We are delighted to welcome Andrew Crook to our management team as Vice President of Operations. His skills and experience will be instrumental in what will be an exciting and busy season for Fireweed as we ramp up to our largest ever drill program with goals to expand all the known mineralized zones. We are also building on our success in recent years by working closely with our Indigenous partners, business partners, and local communities to provide employment and business opportunities while welcoming back many returning staff this year. Perhaps equally exciting is the start of year-round baseline environmental studies as we begin our journey toward production at Macmillan Pass and Mactung."

New Vice President of Operations, Andrew Crook, P.Eng.

Andrew is a registered Professional Engineer with 10 years of experience working with leading mining companies and junior developers where he has demonstrated success leading projects from exploration stage through engineering studies, permitting, and into construction. Andrew helped see Sabina Gold & Silver's Back River Gold Project through studies, permitting, licensing, and early construction including leading field drilling programs and executing complex logistics projects. Most recently, Andrew worked as Deputy Project Director for Kinross Gold's Manh Choh project in northeastern Alaska where he fast-tracked project development and secured Board approval for $255M capital putting the project on track to achieve first gold by 2024.

Operations Update

Preparations are well underway for the biggest drilling campaign in the history of the Macmillan Pass Project. We have secured five drills for the 2023 season with plans to drill at least 16,000 m focused largely on growth through step-out drilling at the Boundary Zone advanced prospect, and step-out and infill drilling at the Tom and Jason deposits. Initial mobilization will occur in May to support camp opening and expansion to eventually support up to 150 people. Drilling is planned to begin in June and continue through to September with the option to extend further into the fall.

Local Procurement and Hiring

Fireweed is proud to be continuing to expand our team of highly skilled personnel with an estimated 40 members from local communities either returning to the Macmillan Pass Project or joining us for their first season at the site. Fireweed is also grateful for the continued dedicated service of local and Indigenous-owned businesses for the upcoming field season, including camp expansion, which was made possible through collaboration with the Dena Nezziddi Development Corporation, which is wholly owned by the Ross River Dena Council.

Commencement of Year-Round Environmental Studies

Fireweed has previously conducted routine environmental monitoring and completed heritage assessments and wildlife studies in accordance with regulatory requirements and guidance for exploration activities. In 2023 continuous year-round field-based studies will commence to support project planning and impact assessment activities to progress towards project approvals for construction and production at both Macmillan Pass and Mactung.

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 approximately C$35,000,000 and is well-positioned to carry out a large 2023 exploration program. The Company has three projects located in Canada:

• Macmillan Pass Zinc-Lead-Silver Project: Fireweed owns 100% of the district-scale 940 km² Macmillan Pass project in Yukon, Canada, which is host to one of the largest undeveloped zinc resources in the world* where the Tom and Jason zinc-lead-silver deposits have current Mineral Resources¹ (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 Assessment² (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 Tungsten Project: The Company recently signed a definitive Asset Purchase Agreement and acquired 100% interest in the 37.6 km² Mactung Tungsten Project located adjacent to the Macmillan Pass Project. Mactung contains historic resources that 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. An updated mineral resource is planned for Q2 2023, and re-sampling of historic drill core is completed and will include assays for previously unreported by-product metals, such as gold, copper, and bismuth, in addition to tungsten.
• Gayna River Zinc-Lead-Gallium-Germanium Project: 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. The results from the 2022 field program of geochemical sampling, airborne LiDAR topographic surveying and ground geophysics are now being interpreted towards defining drill targets.
