With the new addition of Boundary Zone to the Tom and Jason deposits in the 2024 Mineral Resource Estimate, Macpass is positioned as one of the world’s largest undeveloped primary zinc districts*. Combined with additional upside potential from by-product strategic elements gallium and germanium, Macpass has the potential to provide an important source of critical minerals.
Through ongoing regional exploration, Fireweed has identified other high-potential targets along a highly prospective northwest-trending corridor. Fireweed continues to advance the project through systematic exploration and drilling, technical and environmental studies, and social engagement.

2024 Highlights So Far
2023 Highlights
Tom is a high-grade sediment-hosted zinc-lead-silver deposit with an updated 2024 Mineral Resource Estimate. Mineralization is stratabound and comprises finely laminated stratiform pyrite, sphalerite, and galena associated with barite-rich layers, grading to semi-massive and massive sulphides.
Camp facilities at Tom form the logistical hub of the property, with road access and a government airstrip already in place.
17.52 Mt Indicated at 9.90% ZnEq
18.94 Mt Inferred at 9.10% ZnEq
Boundary Zone is another high-grade sediment-hosted zinc-lead-silver deposit, with an inaugural 2024 Mineral Resource Estimate. Stratiform, stratabound mineralization similar to Tom and Jason is present, cross-cut by later replacement- and vein-style pyrite, sphalerite, and galena mineralization.
34.34 Mt Indicated at 5.63% ZnEq
17.46 Mt Inferred at 3.75% ZnEq
Jason is a high-grade sediment-hosted zinc-lead-silver deposit with an updated 2024 Mineral Resource Estimate. Mineralization is the same style as at Tom – stratabound, laminated stratiform pyrite, sphalerite, and galena, grading to semi-massive and massive sulphides.
3.80 Mt Indicated at 9.09% ZnEq
11.65 Mt Inferred at 10.40% ZnEq
End Zone is 3.5 km northwest of Jason and hosts similar high-grade zinc-lead-silver mineralization. The inaugural 2024 Mineral Resource Estimate includes
0.34 Mt Indicated at 16.15% ZnEq
0.44 Mt Inferred at 8.76% ZnEq

For details, see Fireweed News Release dated September 4, 2024. A Technical Report disclosing the mineral resources will be available within 45 days of the News Release. The resource estimate is preliminary in nature and does not include any mineral reserves. It is equally emphasized that the mineral resources disclosed are not mineral reserves and do not have demonstrated economic viability.
