Fireweed Hits 30 Metres of 33.2% ZincEq at Macmillan Pass

Fireweed Metals Expands High-Grade Zinc Zone at Tom South

Fireweed Metals Corp. (TSXV: FWZ) has announced a major zinc-lead-silver intercept from its 2025 drilling at Macmillan Pass. Hole TS25-001D1 returned 30 metres true width of 33.2% ZincEq, a standout result in project history. The hole was a 115-metre down-dip step-out at Tom South Zone, which continues to deliver robust grades.

Macmillan Pass lies 350 km northeast of Whitehorse in Yukon. It’s one of the world’s top undeveloped zinc projects. This intercept sits outside the 2024 mineral resource boundary, pointing to strong expansion potential. The mineralized zone contains laminated to massive sulphides with sphalerite, galena, and minor chalcopyrite.
The zone remains open at depth and up-dip, supporting further growth through drilling.

Fireweed’s stock rose 3.13% to $2.96 on the news. The company plans to drill more holes to define the zone’s full scale. This strengthens Macmillan Pass as a key growth asset in the global zinc sector.

Zinc Exploration at Macmillan Pass Reinforces District-Scale Potential

Tom South has become a high-priority target following a historic intercept re-tested in 2023. Fireweed’s team expanded the zone with wide step-outs, confirming continuity of high-grade mineralization. Hole TS25-001D1 confirmed thick, high-grade zinc-lead-silver in a new step-out.

Fireweed’s September 2024 NI 43-101 report showed strong resources across several zones. It listed 56 Mt indicated at 7.27% ZincEq and 48.49 Mt inferred at 7.48% ZincEq. However, the 2025 Tom South intercept came after the cut-off for that estimate. This means the new result is not yet part of the official resource.

Drilling will continue both down-dip and up-dip at Tom South. If new holes match current grades, the zone could grow significantly. This positions Macmillan Pass for strong resource upgrades and future development.

SuperMetalPrice Commentary:

Fireweed’s recent success at Macmillan Pass signals a turning point for the zinc sector. With a 33.2% ZincEq intercept over 30 metres, the company is proving that untapped high-grade zones remain at depth. This drill result not only strengthens the economics of the Tom Deposit but also opens the door to district-wide resource upgrades. As global zinc demand continues rising—driven by infrastructure growth and battery storage—assets like Macmillan Pass will become strategic focal points. Investors and industry analysts should keep a close eye on Fireweed’s next drill results, which could further elevate the project’s valuation and position it as a future development candidate.
