FIREWEED METALS CORP. reported its best drill intersection from Boundary Zone to date, as well as other spectacular assay results from its 2023 exploration at the Macmillan Pass Project, Yukon, Canada. The drill holes in this release are located in the central and western areas of Boundary Zone and targeted the stratiform to massive sulphide body with a focus on stepping out from known feeder-style mineralization.

NB23-028 intersected a broad, high-grade interval of massive sulphides rich in zinc, lead, and silver that are correlated with this interpreted feeder zone. Stratiform massive sulphides were also intersected in NB23-022 and NB23-029. Stratiform sulphides intersected in NB23-022D1, NB23-029D1 are associated with a separate zone that requires additional drilling and interpretation.

Breccia and vein mineralization was also intersected in NB23-028, NB23-029, NB23-029D1 and NB23-031. Fireweed continues to successfully intersect pyrite-sphalerite-galena as stratiform massive sulphides, laminated mineralization, veins, and breccias in the 2023 step-outs. Mineralization has been intersected in every step-out hole that has been completed to depth.

Assays have been received for 34 Boundary Zone holes. Summaries for new drill results reported in this news release are as follows: Hole NB23-028 intersected a 143.95 m interval of stratiform massive sulphide grading 14.45% zinc, 1.15% lead, and 60.0 g/t silver with an estimated true width of approximately 50 m, including 28.71 m (estimated true width 10 m) of 25.52% zinc, 1.27% lead, and 91.3 g/t silver, further including 10.14 m (estimated true width 3.5 m) of 32.72% zinc, 1.34% lead, and 109.8 g/t silver. Two intervals of vein and breccia style mineralization were also intersected, 19.40 m grading 3.65% zinc and 5.1 g/t silver, and 7.70 m grading 9.95% zinc and 12.7 g/t silver.

Hole NB23-022 intersected 66.11 m of stratiform massive sulphide with an estimated true width of 18 m grading 7.13% zinc, 0.97% lead, and 54.8 g/t silver, including 50.08 m (14 m true width) of 7.99% zinc, 1.12% lead, and 61.7 g/t silver. Hole NB23-29D1 is a directionally-cut secondary splay hole from NB23-029 and intersected 20.75 m of stratiform massive sulphide grading 5.20% zinc, 2.05% lead, and 52.6 g/t silver, including 6.50 m of 8.43% zinc, 3.27% lead, and 82.3 g/t silver. This intercept of stratiform mineralization correlates to a separate, distinct body from the primary tabular massive sulphide.

NB23-029 intersected a 5.76 m interval of stratiform massive sulphide grading 6.32% zinc, 1.50% lead, and 34.6 g/t silver, as well as an 11.63 m interval of stratiform massive sulphide grading 7.49% zinc, 1.66% lead, and 34.7 g/t silver. Four intervals of vein and breccia style mineralization were also intersected: 27.81 m grading 4.28% zinc and 11.9 g/t silver; 29.18 m grading 2.93% zinc and 4.6 g/t silver; 16.62 m grading 8.74% zinc and 11.1 g/t silver; and 38.40 m grading 3.06% zinc and 8.2 g/t silver. Hole NB23-032 intersected 18.37 m of stratiform massive sulphide with an estimated true width of 8 m grading 4.25% zinc, 0.14% lead, and 12.7 g/t silver, including 4.45 m of 7.55% zinc, 0.19% lead, and 17.3 g/t silver with an estimated true width of 2 m. Hole NB23-031 intersected three zones of breccia and vein style mineralization: 6.50 m grading 7.33% zinc and 14.5 g/t silver; 4.59 m grading 7.33% zinc and 7.7 g/t silver; and 4.27 m grading 7.95% zinc and 3.3 g/t silver.

Hole NB23-022D1 is a directional cut off NB23-022 and intersected a 2.50 m interval of sulphide mineralization grading 5.13% zinc, 0.43% lead, and 33.8 g/t silver. 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: NB23-034 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 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. The mineralization in the massive stratiform layer extends from surface to at least 450 m down-dip, over 550 m in strike with a variable true thickness that is shown on Long Section M?M?, thinning around the edges and reaching thicknesses of up to 50 m at its widest point. Extensive vein and breccia mineralization at Boundary Zone occurs both stratigraphically above and below the main stratiform laminated massive sulphide zone.

This mineralization forms within a halo approximately 100 m to 150 m wide on both sides of the stratiform laminated zone and is interpreted as a stockwork of randomly oriented veins and breccia zones. 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.

Use of directional drilling, in which multiple secondary 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. This was Fireweed?s largest ever program and the biggest drill program in Yukon in 2023.
