Macmillan Pass - Zinc
The Macmillan Pass Project, located in Canada’s mining-friendly Yukon Territory, is host to large zinc-lead-silver deposits. The project is accessible via the North Canol Road off the Robert Campbell Hwy in southeast Yukon. The territorial government is highly supportive of the mining industry and the Yukon is one of Canada’s top provinces for new mine developments.
Since the company’s inception in 2017 Fireweed progressively expanded the property to 948 km2. The new areas include an along-strike continuation of the highly prospective Fertile Corridor that has never been systematically explored for zinc-lead-silver deposits.
TOM & JASON
- Fireweed’s Macmillan Pass Project includes the large Tom and Jason zinc-lead-silver deposits.
- The January 2018 Mineral Resource Estimate puts Macmillan Pass among the world’s most significant zinc resources.
- The Tom and Jason deposits contain a combined resource of:
- 11.21 Mt Indicated @ 9.61% ZnEq
- 6.59% Zinc, 2.48% Lead, 21.33 g/t Silver
- 39.47 Mt Inferred @ 10.00% ZnEq
- 5.84% Zinc, 3.14% Lead, 38.15 g/t Silver
- 11.21 Mt Indicated @ 9.61% ZnEq
- Significant exploration upside remains, including the potential to expand upon historic work and to utilize modern exploration methods in search of new discoveries.
- Existing camp, road access and a government airstrip are already in place.
- In 2021, three distinct zones of zinc-lead-silver mineralization were intersected in a step-out hole at Boundary West, including a newly discovered zone of high-grade laminated stratiform mineralization similar in style to the Tom and Jason deposits.
- 2021 drilling highlights included intersections of 23.77% zinc, 3.44% lead, and 75.7 g/t silver over 10.42 m
- Drilling in 2020 confirmed the presence of a vein stockwork at Boundary Zone and made the Boundary West discovery 350 m west of the previously known core of mineralization. Drilling intersections included:
212m of 4.42% Zn including 25.58% Zn over 5.81 m
- Drilling on Boundary Zone on the Nidd property in 2019 included intersections of:
- 100 m of 7.94% Zinc from surface including 6.4 m of 42.49% Zinc within 230 m of 4.14% Zinc
- The Nidd claims host established zinc mineralization in the Boundary Zone where historic drilling included intersections of
- 224.0 m of 2.5% Zinc and 0.3% Lead, including 4.5 m of 16.4% Zinc, demonstrating potential for both bulk tonnage open pit and high-grade underground mineralization
- With the acquisition of the Nidd claims, Fireweed owns all four known large zinc mineralized systems in the region – Tom, Jason, Boundary Zone and End Zone – as well as many other zinc exploration targets including the entire highly prospective “fertile corridor” of exploration targets extending from Tom to Boundary Zone and beyond.
- The large Nidd property covers 7,393 hectares in 372 mineral claims which expands Fireweed’s claim holdings in the district to 544 square kilometers.
- Previous work by Teck on the Nidd claims included 35 drill holes (many with significant zinc mineralization) as well as extensive geochemical and geophysical surveys that outlined additional exploration targets.
- End Zone is host to high-grade zinc-lead-silver mineralization. In 2018, drilling at End Zone intersected high grades including 11.08 m of 4.78% Zinc, 10.17% Lead, 87g/t Silver.
- By combining rigorous analysis of historic data with advanced geophysical and geochemical surveys Fireweed has identified numerous additional exploration targets in the Macmillan Pass district.
- These targets include Imperial, Corvus, Kobuk, Eleven, Bog, Volcanic and Ben, each of which has the potential to be a significant deposit.
