Kingfisher identifies porphyry copper system at HWY 37
Executive Summary
- Kingfisher Metals identified a new porphyry copper system beneath the existing Hank epithermal Au‑Ag deposits at the HWY 37 project.
- The redrill (hole HW‑25‑011) intercepted 429 m of continuous copper mineralization from 530 m to the bottom of hole at 959 m depth, extending beyond the planned target depth.
- All 2025 field work at HWY 37 is complete; crews have been demobilized and a comprehensive suite of mapping, sampling, and geophysical surveys has been logged.
Key Details
- Hole HW‑25‑011 (Lower Hank porphyry target)
- Planned depth: 650 m; final depth reached: 959 m.
- Porphyry‑style alteration and mineralization observed from 530 m to 959 m (429 m interval).
- Core shows widespread multigenerational veins, disseminated pyrite, chalcopyrite ± molybdenite; high‑grade copper mineralization at bottom.
-
Three zones intersected:
- 0–530 m: distal low‑temperature quartz‑carbonate alteration, elevated Pb/Zn.
- 530–900 m: proximal porphyry alteration (quartz‑chlorite‑sericite ± epidote‑pyrite) with high pyrite‑to‑chalcopyrite ratios.
- 890–969 m: increasing chalcopyrite‑to‑pyrite ratios, early K‑feldspar‑magnetite veins indicating vector toward heat source/core.
-
Geophysical Support (2025 IP Survey)
- High‑chargeability domains of 30–70 mV/V flank a broader 20–30 mV/V zone, interpreted as pyrite‑rich shell surrounding copper‑sulphide core.
- Resistivity data show a broad resistive feature consistent with a porphyry intrusive core surrounded by conductive clay alteration.
-
Airborne magnetics reveal an ~1,800 m × 900 m magnetic anomaly aligning with the interpreted porphyry system.
-
Hole HW‑25‑009 (Williams root area)
-
Completed to 761 m (short of 800 m target) after encountering continuous flanking alteration; terminated as projected higher‑grade potassic zone was not intersected.
-
2025 Exploration Program Completion
- Drilling total: 7,630 m completed on Sept. 7, 2025.
- All drill cores logged; samples sent to Bureau Veritas (Vancouver) for assay.
- Mapping: 84 person‑days.
- Soil sampling: >750 samples; surface rock sampling: >650 samples.
- IP geophysics: 30.7 km of line‑kilometres surveyed.
- Airborne mobile magnetotellurics (MMT): 1,750 km covering ~319 km².
-

Notable Quotes
“This initial drill test below the extensive Hank epithermal Au‑Ag system encountered a new porphyry copper system… This targeting success is a major advancement in confirming our exploration hypothesis that a large porphyry copper‑gold system is responsible for the broad epithermal Au‑Ag mineralization at Hank on surface.” – Dustin Perry, CEO
Materiality Assessment: Material – Positive (the discovery of a sizable porphyry copper system represents a significant advancement in the company’s exploration model and could materially affect future resource potential).
