Fireweed Assembles Expert Team for Tungsten Project Study

Why It Matters

The updated study de‑risks the project, aligning it with strategic defense supply chains and accelerating permitting, which could unlock significant financing and market share in the critical tungsten sector.

Key Takeaways

• Updated FS targets early 2027 completion
• Wood Canada leads cost and infrastructure planning
• U.S. Defense Production Act backs project financing
• Mactung is among world’s highest‑grade tungsten deposits
• Parallel programs focus on mining, metallurgy, and water management

Pulse Analysis

The global push for resilient supply chains has placed tungsten in the spotlight, given its critical use in hard‑metal tools, aerospace components, and defense and industrial applications. Fireweed Metals’ Mactung deposit, straddling the Yukon‑N.W.T. border, ranks among the world’s highest‑grade tungsten resources, a factor that attracted a Title III award under the U.S. Defense Production Act. By securing federal backing, Fireweed not only gains financial certainty but also aligns the project with national security priorities, a rare advantage for a junior miner.

Delivering a technically robust feasibility study in the Yukon demands expertise in cold‑weather engineering, remote logistics, and stringent environmental standards. Fireweed’s selection of Wood Canada, SLR Consulting, Ausenco, Worley, Knight Piésold, and Lorax reflects a deliberate strategy to cover every discipline—from updated resource modeling and underground mine design to metallurgical flowsheet optimisation and comprehensive water‑balance modelling. These firms bring proven track records on northern projects, ensuring that cost estimates, geotechnical designs, and permitting packages meet both industry benchmarks and Yukon regulatory expectations.

The updated FS, slated for early 2027, will feed directly into Fireweed’s mine‑licensing dossier and shape the capital‑raising narrative for the next development phase. By integrating over 11,000 m of 2025 drilling with decades of historic data, the study aims to sharpen the resource estimate, optimise early‑stage high‑margin mill feed, and de‑risk water‑management challenges that often stall northern projects. Successful completion could position Mactung as a cornerstone of North American tungsten supply, attracting strategic investors and potentially unlocking downstream processing partnerships, while reinforcing Canada’s role in critical mineral security.
