Fireweed Intersects Zinc Mineralization in 300 m Step Out at Tom South and Provides Macpass Regional Update
Fireweed Proves District Scale with Massive Step-Outs as Lundin-Backed Aggression Tests Northern Frontier
The most recent news release (January 15, 2026) confirms the completion of a nearly 20,000-meter drilling program for 2025. The highlight is a significant 300-meter step-out drill hole (TS25-003) at the Tom South deposit (Macpass Project), which intersected 58.3 meters of laminated zinc mineralization. Critically, the hole was terminated prematurely due to winter conditions while still in mineralization, suggesting the zone remains open at depth. Additionally, regional exploration at the Oro target yielded gold intercepts (e.g., 13m at 0.45 g/t Au), and the company provided a summary of its 2025 activities across Mactung (tungsten) and Gayna (zinc).
This news is materially positive for several reasons: - Scalability of Tom South: Following a previously reported 115m step-out (TS25-001D1) that hit 30m true width of 33.2% ZnEq, the 300m step-out in TS25-003 confirms that the mineralization is not localized but part of a much larger system. - Feeder Zone Potential: Management's interpretation that the laminated sulphides in TS25-003 sit above a massive sulphide "feeder zone" provides a clear, high-grade target for the start of the 2026 season. - Asset Diversification: While primarily a zinc-lead-silver story, the gold results at Oro and the peerless tungsten grades at Mactung (up to 6.21% WO3) reduce the company's reliance on a single commodity cycle. - Operational Execution: Completing ~20,000 meters in a remote Yukon/NWT environment with six rigs demonstrates high-level logistical capability, likely bolstered by the Lundin Group’s technical influence.
Fireweed Metals is a leading explorer in the Yukon, Canada, focused on the Macpass District. Its flagship consists of the Macpass Project (Zinc-Lead-Silver-Gallium-Germanium) and the Mactung Project (Tungsten). Macpass is one of the world's largest undeveloped zinc resources. Mactung is considered the world's largest high-grade tungsten deposit outside of China. The company also holds the Gayna project, a large-scale zinc target in the NWT.
