Fireweed Metals is a mineral developer centered on the Macmillan Pass district (zinc, lead, silver, copper) and the adjacent high‑grade Mactung tungsten project. Macpass spans about 985 km² and includes the Tom, Jason, Boundary and End Zone deposits; an updated calculation (four deposits) reported 56 million tonnes indicated at 5.49% zinc, 1.58% lead and 24.2 g/t silver, plus 48.49 million tonnes inferred at 5.15% zinc, 2.08% lead and 25.3 g/t silver. Mactung was reported in 2023 to host 41.5 million tonnes indicated averaging 0.73% WO3 and 12.3 million tonnes inferred averaging 0.59% WO3. The company is advancing planning and early engineering for infrastructure upgrades (road and transmission) to enable long‑term development of both Macpass and Mactung. Financially, Fireweed has secured government support including a C$12.9M contribution from Natural Resources Canada and a prior U.S. Department of Defense Title III award of $15.8M to support feasibility and development work at Mactung. Planned work funded by the Canadian contribution includes preliminary engineering for ~250 km of road upgrades, transmission line upgrades and new 138 kV transmission planning, plus environmental and socio‑economic assessments and government/Indigenous negotiations. Construction funding for the infrastructure upgrades has not been determined and is expected to involve multiple sources.
