Junior exploration company Fireweed Metals (TSXV:FWZ) has announced new drill results from its 2023 exploration program at the Macmillan Pass Project in Yukon, Canada. The results include the best drill intersection to date from the Boundary Zone target, as well as other high-grade assay results.
Brandon Macdonald, CEO of Fireweed Metals, commented in a press release: “I am excited to start the year able to say that we have intersected our best-ever Boundary Zone drill intersection. We stepped out 140 m along strike from NB22-002 and NB23-007 and hit a spectacular intersection in NB23-028, further supporting our interpretation that there is a continuous high-grade feeder zone within the stratiform unit at Boundary Zone. We now have multiple wide and high-grade intersections that highlight the potential for another large zinc system within this exceptional critical minerals project.”
The mineralization encountered in the latest drill holes at Boundary Zone consists primarily of stratiform (layer-parallel) and massive sulphide zones containing zinc, lead and silver. The sulphide bodies occur over a 550-metre strike length and have been traced from near-surface to depths of at least 450 metres.
Drill hole NB23-028 intersected a broad zone of high-grade massive sulphides interpreted to be associated with a feeder system that supplied metals to the Boundary mineralized system. Additional stratiform massive sulphide zones were hit in holes NB23-022 and NB23-029.
According to Fireweed, step-out drilling has successfully extended the known stratiform sulphide zone down-dip. The tabular stratiform mineralized body ranges from 10 to 50 metres in true thickness. Extensive vein and breccia mineralization has also been encountered adjacent to the main sulphide zone.
In 2023, Fireweed completed a 22,500-metre drill program focused on the Boundary, Tom and Jason zones, as well as several metallurgical drill holes. The large program utilized directional drilling technology to maximize efficiencies.
Assays are still pending for numerous drill intersections from the Boundary Zone where visual inspections identified significant zinc and lead sulphide mineralization. Fireweed reports that step-out drilling has resulted in the visual identification of many wide intervals of sphalerite and galena.

The drill results continue to support the interpretation that the mineralization at Boundary Zone consists of a laterally extensive stratiform sulphide layer. According to Fireweed, this tabular mineralized zone now measures 550 metres along strike and has been traced 450 metres down dip. It remains open in multiple directions.

Highlights from the results are as follows:
Best intersection drilled to date at Boundary Zone: hole NB23-028 intersected 143.95 m (50 m true width) grading 14.45% zinc, 1.15% lead, and 60.0 g/t silver, including 28.71 m (10 m true width) grading 25.52% zinc, 1.27% lead, and 91.3 g/t silver.
Successful step-out holes continue to increase the extents of known zinc mineralization and demonstrate the high-grade tenor of the Boundary Zone mineralization.
Hole NB23-022 intersected 66.11 m (18 m true width) grading 7.13% zinc, 0.97% lead, and 54.8 g/t silver.
Assays are pending for 19 remaining drillholes including six more from Boundary Zone, and 11 holes from the Tom deposit, and two holes from the Jason deposit.

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.

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.
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.
