Kingfisher Metals drills 234.35 m of 1% CuEq at HWY 37

Executive Summary

• Drill hole HW‑25‑004 intersected a massive 557.8 m of 0.64 % CuEq, including 234.3 m at 1.00 % CuEq – one of the highest‑grade, longest intercepts ever reported from the Williams porphyry copper‑gold deposit.
• The intercept confirms extensive bornite‑rich mineralization down to 340 m elevation (140 m deeper than previously known), supporting the company’s exploration model and de‑risking broader project targets.
• Overall 2025 drilling program completed 7,630 m across eight holes, accompanied by extensive mapping, soil/rock sampling, IP, airborne MMT, and LiDAR surveys.

Key Details

• Hole HW‑25‑004:
• Total intercept: 557.8 m @ 0.64 % CuEq (0.29 % Cu, 0.30 g/t Au, 1.6 g/t Ag) from 328.10 m depth.
• High‑grade sub‑interval: 234.35 m @ 1.00 % CuEq within the above interval.
• Geological significance:
• Extends bornite‑rich mineralization to 340 m elevation, 140 m deeper than historic data.
• Indicates a hot core of sulphide system with bornite > chalcopyrite, often associated with elevated gold grades.
• Drilling program summary (completed 7 Sept 2025):
• Total depth drilled: 7,630 m across holes HW‑25‑001, ‑002, ‑003, ‑004, ‑006, ‑008, ‑009 (assayed).
• Holes HW‑25‑005 and ‑007 failed and will not be assayed.
• Field work performed:
• 84 person‑days of geological mapping.

• 750 soil samples and >650 surface rock samples collected.

• 30.7 km of IP (induced polarization) geophysics.
• 1,750 km of airborne mobile magnetotellurics (MMT) covering ~319 km².
• LiDAR survey over 256 km².
• QA/QC procedures:
• On‑site supervision with full QA/QC program (coarse blanks, pulp blanks, standards, duplicates).
• Samples sealed with tamper‑proof seals and sent to Bureau Veritas (BV) lab in Vancouver for analysis under ISO/IEC 17025:2017.

• Qualified Person: Tyler Caswell, P.Geo., VP Exploration, Kingfisher Metals (NI 43‑101 qualified).

Notable Quotes

“In these initial drill results, we see clear confirmation of our exploration concepts – consistent vertical grade and expansion of the bornite‑rich stockwork. The new data de‑risks the broader project targets, justifies future drill metres and strengthens our conviction that we're advancing a value‑creating asset for shareholders.” – Dustin Perry, CEO, Kingfisher Metals Corp.
