FIREWEED METALS CORP. report additional assay results from its 2023 exploration at the Macmillan Pass (?Macpass?) Project, Yukon, Canada, and provide an update from its largest ever drill program. Following up on drilling from 2022 and the compelling initial results of the 2023 program to date, Fireweed continues to test the extents of the high-grade feeder zone target.

This zone is interpreted to occur as at least one tabular layer within a broader sediment hosted massive sulphide system. Drilling also continues to define the more distal expressions of this stratiform system near surface, as well as delineating the extensive replacement, vein, and breccia styles of mineralization. The results from 2023 continue to return high-grade zinc values that support the stratiform mineralization model, as well as better defining the vein, breccia and replacement mineralization near surface.

Fireweed continues to successfully intersect pyrite-sphalerite-galena as stratiform massive sulphides, laminated mineralization, replacement mineralization, veins, and breccias in the 2023 step-outs. Zinc mineralization has been intersected in every step-out hole that has been completed to depth. Assays have been received for the first sixteen Boundary Zone holes.

Hole NB23-016 intersected an 81.34 m interval of stratiform massive sulphide grading 8.46% zinc, 1.06% lead, and 47.0 g/t silver with an estimated true width of approximately 35 m. In addition, two other distinct intervals were intersected, comprising 12.84 m of 4.54% zinc, and 8.8 g/t silver, and 7.68 m of 6.87% zinc, and 9.5 g/t silver. Hole NB23-012 intersected a 67.78 m intersection (41 m estimated true width) correlated with the stratiform massive sulphides grading 6.26% zinc, 1.22% lead, and 52.0 g/t silver and a 26.17 m interval of vein mineralization grading 3.18% zinc and 8.4 g/t silver. Hole NB23-011 intersected 44.83 m of stratiform massive sulphide (8.5 m estimated true width) grading 8.30% zinc, 1.16% lead, and 42.9 g/t silver, and two other intercepts of vein style mineralization: 7.99 m grading 4.47% zinc and 8.9 g/t silver; and 9.03 m grading 3.69% zinc, 0.31% lead, and 26.4 g/t silver.

Hole NB23-013 intersected 29.77 m (20 m estimated true width) of stratiform massive sulphide grading 2.87% zinc, 0.28% lead and 27.7 g/t silver, as well as two intervals of vein style mineralization: 5.35 m grading 8.31% zinc, 0.25% lead, and 31.0 g/t silver; and 5.55 m grading 7.71% zinc, 0.68% lead, and 32.9 g/t silver. Hole NB23-015 intersected two zones of vein style mineralization: 95.87 m grading 3.21% zinc, 1.06% lead, and 18.5 g/t silver; and 43.98 m grading 1.99% zinc, 0.68% lead, and 13.1 g/t silver. Hole NB23-014 intersected 12.17 m of stratiform massive sulphide grading 4.27% zinc, 1.51% lead, and 38.3 g/t silver.

Hole NB23-010 intersected a distal, near surface expression of the stratiform mineralization that graded 1.79% zinc, 0.40% lead, 9.6 g/t silver over 3.09 m. Hole NB23-009 was abandoned at 67 m due to ground conditions and redrilled as NB23-011. Step-out drilling at Boundary Zone targeting the massive?stratiform zone has resulted in the visual identification of many wide intersections of zinc-lead mineralization with assays pending. The most significant intersections can be seen on Long Section M-M? and are listed here: NB23-019 intersected 57 m of massive sulphide.

NB23-022 intersected 55 m of massive sulphide. NB23-028 intersected 140 m of feeder-proximal laminated to massive sulphides. NB23-029D1 intersected 21 m of stratiform massive sulphide.

NB23-032 intersected 18 m of stratiform massive sulphide. NB23-034 intersected 49 m of stratiform massive sulphide. NB23-035 intersected 15 m of stratiform massive sulphide.

NB23-036 intersected 45 m of stratiform massive sulphide. NB23-037 intersected 110 m of feeder-proximal laminated to massive sulphide. NB23-038 intersected 13 m of stratiform massive sulphide.

Out of the 40 holes drilled at Boundary Zone in 2023, 36 were step-out holes that tested the replacement and vein mineralization, laminated stratiform mineralization, and massive sulphide zones. The geometry and stratigraphic sequence intersected in these holes continue to support the idea that the laminated and massive sulphide mineralization are part of the same geological layer at Boundary Zone, forming an approximately tabular stratiform zone. Step out drilling down-dip intersected abundant galena, supporting the presence of the conceptual feeder zone.

While this remains a preliminary interpretation of the available geological data, continued drilling supports this model, extending the depth of mineralization in the massive stratiform layer from surface to at least 400 m, with the zone becoming higher grade and wider in the deeper intersections (Long Section M-M?). Extensive vein, breccia, and replacement mineralization at Boundary Zone occurs both above and below the main stratiform laminated massive sulphide zone. Many wide intervals of vein, breccia and replacement style sphalerite mineralization have been encountered in 2023 step-out holes and four infill holes.
