Multiple Geophysical Datasets Support Increased Target Dimensions at Hank Copper-Gold Discovery, HWY 37 Project, Golden Triangle

Kingfisher Metals Corp. has released comprehensive geophysical results from its Hank copper-gold discovery within the 933 km² HWY 37 Project in British Columbia's Golden Triangle. The company conducted multiple surveys in 2025, including 1,825 line-km of Mobile MagnetoTellurics (MMT), 22.3 line-km of IP-resistivity surveying, and compiled historical airborne magnetic data for 3D inversions. These integrated datasets reveal a significant low resistivity anomaly covering approximately 3.5 by 4.4 km, interpreted as hydrothermal clay alteration related to the porphyry system.

The magnetic vector inversion model outlines a large alteration footprint consistent with magnetite destruction and remanent magnetization observed in surface and drill core samples. Expanded IP-resistivity surveys identified a >2 km wide anomaly coinciding with the interpreted potassic altered core. Cross-sections demonstrate the extent of alteration, with high chargeability highlighting the core target area. Drillhole HW-25-011 confirmed significant mineralization matching the geophysical anomalies, with abundant pyrite and sericite supporting magnetite destruction patterns typical of flanking phyllic alteration.

Petrographic analysis of thin sections from HW-25-011 revealed high fertility indicators including bornite and tennantite, along with electrum grains measuring 5-10 microns near syn-mineral intrusions. The study confirmed complex mineralogy and widespread magnetite-destructive alteration associated with the porphyry system. The resistivity data outlines a broad, low-angle blanket of conductive rock interpreted as widespread clay alteration, with a pronounced mushroom-shaped conductivity zone marking fluid pathways in the porphyry-epithermal system.

These results provide Kingfisher with enhanced confidence for its 2026 field program, where the company plans to aggressively expand upon what it describes as the newest Cu-Au porphyry discovery in BC's Golden Triangle. The systematic three-year exploration approach combining multiple geophysical, geological, geochemical, and spectral surveys has established a robust 3-dimensional targeting framework for future drilling campaigns. The scale and continuity of the geophysical anomalies suggest significant potential for a major porphyry copper-gold system.
