Fireweed Metals drills 51.22 m of 4.4% Zn at Gayna

Executive Summary

• Fireweed Metals Corp. released results from its 2025 exploration program at the Gayna property in the Northwest Territories, marking the first drilling at the project since the late 1970s.
• The program successfully intersected significant zinc-lead-silver mineralization at the Intrepid target, validating the prospectivity of the project and advancing the understanding of the geological system.
• A total of approximately 3,800 meters were drilled across multiple targets (Intrepid, Jaws, Zuviel, and Propitious), with the most significant intercepts occurring at Intrepid.

Key Details

• Program Overview: The 2025 program totaled approximately 3,800 meters and tested a new exploration model targeting steeply dipping Zn-Pb-Ag sulphide mineralization hosted within Neoproterozoic reef margins.
• Intrepid Target Highlights:
  • Hole GR25-013: Intersected 51.22 m grading 4.44% Zn from 31.31 m downhole, including 24.00 m of 7.34% Zn and 5.17 m of 10.04% Zn. Additional intervals included 7.99 m of 2.37% Zn and 5.09 m of 4.80% Zn.
  • Hole GR25-012: Intersected 17.84 m grading 3.39% Zn from 35.74 m downhole, including 3.00 m of 6.32% Zn.
  • Hole GR25-009: Intersected 2.00 m grading 9.29% Zn and 5.29 m grading 2.02% Zn from 224.03 m downhole.
• Geological Context: Mineralization consists of vein-hosted and replacement-style zinc-lead mineralization (sphalerite and galena). True width estimates are preliminary, assumed to be 70-90% of intersected thicknesses based on 2-D cross-sectional interpretation.
• Jaws Target: Five holes drilled; all intersected trace to minor vein-hosted galena and/or sphalerite. No significant mineralization or reef rocks were intersected.
• Zuviel Prospect: One hole (GR25-005) intersected the top of a buried reef with trace vein-hosted sphalerite; no significant mineralization observed.
• Propitious Target: Preliminary gravity survey results showed a large gravity anomaly on the northwestern margin. Hole GR25-016 intersected minor sphalerite mineralization but no significant mineralization at the reef contact.
• Government Grant: Fireweed Metals was awarded a mining incentive program (MIP) grant from the Government of the Northwest Territories valued at $216,830, which reduced the cost of the 2025 program.
• Next Steps: The company intends to interpret geological data and geophysics to refine potential targets, using new density data to reinterpret gravity survey data and vector toward near-reef density anomalies.

Notable Quotes

• "Our first season of drilling at Gayna successfully intersected significant zinc and lead mineralization at the Intrepid target, validating the prospectivity of the project. This program has advanced our understanding of these systems and provides important insights to guide potential future exploration. We will continue to interpret the encouraging results from our ambitious and multifaceted field season at Gayna, Mactung and Macpass, and plan to responsibly advance our projects at a rapid and practical pace." — Ian Gibbs, President and CEO
