Fireweed to complete updated FS for Mactung

The most recent news (March 9, 2026) announces that Fireweed Metals has engaged a suite of international consultants (Wood, SLR, Ausenco, Worley, Knight Piesold, and Lorax) to complete an updated Feasibility Study (FS) for the Mactung Tungsten Project. This follows a successful 2025 field season. The FS is expected to be completed in early 2027, supporting mine license applications later that year. Notably, this work is supported by a U.S. Department of Defense (DPA Title III) award announced in late 2024.

• Operational Progression: This is a logical and expected step following the 2025 drilling program. While "Routine - Positive" because it follows the previously announced strategy, the caliber of the consultants (e.g., Ausenco, Wood) signals a high level of technical rigor.
• Strategic De-risking: The project is significantly de-risked by the U.S. Department of Defense funding ($22.5M CAD award), which covers a substantial portion of the feasibility costs. This reduces the immediate dilutive burden on shareholders for this specific workstream.
• Timeline Clarity: The market now has a firm target (early 2027) for the FS and subsequent permitting.
• Social License: The February 2026 agreement with the Ross River Dena Council (RRDC) is a critical precursor to this FS, ensuring that the engineering designs incorporate Indigenous-led assessment processes (TAP), reducing future litigation or permitting delay risks.

Fireweed Metals is a leading explorer and developer of critical minerals in the Yukon and NWT, Canada. - Mactung (Tungsten): The world’s largest high-grade tungsten deposit. Currently in the Feasibility stage. - Macpass (Zinc-Lead-Silver): A district-scale project including the Tom and Jason deposits. Recent drilling at Tom South has returned "game-changing" grades (e.g., 30m true width at 33.2% ZnEq). - Gayna (Zinc-Lead-Silver-Gallium-Germanium): An earlier-stage but high-potential project testing new geological models.
