Fireweed Metals (TSX-V:FWZ) reports massive sulphides in a 180m step-out hole at its Tom South deposit within the Macpass Project in Yukon, Canada.
The company intersected 64m true width of 5.42% zinc (Zn), 3.21% lead (Pb), and 16.77 grams per tonne silver (Ag) from 982.34m to 1,093.97m in hole TS26-003, representing a zinc equivalent grade of 10.53%.
Within this primary interval, Fireweed identified a 43m true width sub-interval grading 6.63% Zn, 4.28% Pb, and 22.39g/t Ag, equivalent to 12.96% Zn.
The intersection comprises black, grey, and pink facies material as well as massive sulphides consisting of laminated sphalerite, galena, and barite. The mineralisation contains bedding and sedimentary laminae ranging from sub-parallel to perpendicular to the core axis.
“Drilling at Tom South continues to deliver another wide intersection in our farthest eastern step-out to date from known mineralisation,” CEO Ian Gibbs says.
The drill hole constitutes a 180m step-out down dip and east along strike of hole TS25-001D1, following the orientation of ‘high-grade’ laminated and massive sulphide mineralisation on the fold hinge at Tom South.
Fireweed notes the intersection represents the thickest zone drilled to date at Tom South and sits outside the spatial extents of the current Macpass mineral resource estimate.
The hole also contains elevated levels of critical minerals germanium and gallium, with the primary interval averaging 13.50 parts per million (ppm) germanium and 6.04ppm gallium.
Fireweed currently operates three active drill rigs at Macpass as part of its 2026 exploration program, completing 6,505m of drilling to date. The company has drilled 4,710m at Tom South targeting massive sulphide mineralisation and 1,795m at Tom East targeting ‘high-grade’ massive and laminated sulphides.
The company has completed its 2026 Mactung drilling program, finishing 2,099m of drilling in support of the Feasibility Study currently under way.
Fireweed Metals will release additional results from Tom South, Tom East, and Mactung as they are received and interpreted.
