Fireweed METALS Corp. reported additional assay results from its 2023 exploration at the Macmillan Pass ("Macpass") Project, Yukon, Canada. Highlights: Boundary Zone delivers multiple near-surface wide, high-grade zones of zinc-lead-silver mineralization in step-out holes within breccia and vein mineralization, as well as stratiform and massive sulphides.

Assays are pending for 24 remaining drill holes from Boundary Zone, 10 holes from the Tom deposit and two holes from the Jason deposit. Summary: The drill holes in this release primarily comprise near surface mineralization present as veins and breccia (fractured rock infilled by zinc and lead sulphides) on the eastern side of Boundary Zone. Many wide intervals of vein and breccia style sphalerite mineralization have been encountered in 2023 step-out holes and four infill holes.

The 2023 program achieved 22,500 m of drilling mostly focused on Boundary, Tom, and Jason zones in addition to five metallurgical drill holes at Mactung (Map 1). Use of directional drilling, in which multiple angled drill holes are initiated at depth from one primary hole, saved an estimated 1,800 m of drilling compared to traditional drilling of multiple new holes from surface for a total equivalent metreage of 24,300 m in 2023, making this Fireweed's largest ever program and the biggest exploration program in Yukon this year. Data Verification: The diamond drill core logging and sampling program was carried out under a rigorous quality assurance /quality control program using industry best practices.

Drill intersections in this release are NQ2 size core (50.5 mm/1.99-inch diameter) with recoveries typically above 85% unless otherwise noted in the results tables. Standards and blanks in 2023 drill results to date have been approved as acceptable. Duplicate data add to the long-term estimates of precision for assay data on the project and precision for drill results reported is deemed to be within acceptable levels.

True widths for primary intervals are estimated by measuring perpendicular to strike within the short axis of a stratiform wireframe that has been constructed in 3D around the mineralized intercepts at Boundary Zone based on assay results, geological logging, stratigraphic correlation, and bedding measurements from oriented core. No absolute visual estimates of mineral abundance or inferences of potential zinc or lead grades have been stated for holes without assay values in this news release. All statements, other than statements of historical facts, included herein, including, without limitation, statements relating to interpretation of drill results and projections of mineralization, future work plans, the use of funds, and the potential of the Company's projects, are forward looking statements.
