Kingfisher Metals (TSXV:KFR) has provided a detailed update on its 7,500-meter drilling campaign at the HWY 37 Project, a large-scale copper-gold exploration initiative located in British Columbia’s Golden Triangle. The company’s latest efforts have focused primarily on the Williams porphyry copper-gold system and additional targets across the project area, including Upper and Lower Hank.

Dustin Perry, CEO, commented in a press release: “So far, the 2025 drill program has matched our expectations of vertically extending porphyry mineralization at Williams as well as providing a much clearer understanding of this highly prospective district. Our exploration hypothesis indicates vertical continuity of the gold-rich bornite zone, and these holes demonstrate that bornite continues to depth where it was predicted.”

The 849 square-kilometre HWY 37 Project is among the largest contiguous land positions in the Golden Triangle, consolidated by Kingfisher through purchases and option agreements.

Drilling Expands Mineralized Zone at Williams Target

Drilling at the Williams area has returned notable results, extending known potassic alteration and associated copper sulfide mineralization. Hole HW-25-004 intersected intense potassic alteration over a 478-meter interval, with chalcopyrite and bornite present as vein, stringer, disseminated, and blebby mineralization. This mineralized zone extended approximately 150 meters below the limits of historical drilling, with bornite now confirmed from surface to a vertical depth of 680 meters. The hole ended at 884.9 meters, continuing to show traces of chalcopyrite to the bottom.

The drill hole was located upslope and north of the previously defined potassic zone, targeting a deeper extension of the system. After passing through the Williams thrust fault at 327 meters, the drill intersected copper-bearing mineralization down to the end of the hole.

The company stated that these findings build on the mineralogical information from historical drill hole HNK-18-013, offering additional insights into the system’s depth and geometry.

Geological Interpretation and Intrusive Phases

Earlier in the program, hole HW-25-001 was drilled from the west of the main alteration zone. Despite complications related to faulting and directional deviation from its planned azimuth, the hole still intersected potassic and phyllic alteration with chalcopyrite and minor bornite from 390 to 726 meters, bottoming in early mineral monzanite at 803 meters. Notably, the drilling identified two distinct porphyry intrusive phases, which had previously been categorized as a single unit. The distinction is expected to improve geological modeling and guide future drill targeting.

Hank Creek and Eastern Targets

Drill holes HW-25-002 and HW-25-003 were designed to test shallow chargeability anomalies southeast of Williams, across Hank Creek. Both holes intersected widespread quartz-sericite-pyrite-carbonate alteration in the upper 250 to 350 meters before entering a polyphase diatreme breccia interpreted to pre-date the mineralizing events at Williams. Diatreme breccias of this nature are often linked to porphyry copper-gold systems and are typically emplaced either before or after the main mineralizing phase.

Surface mapping combined with drill data suggests that several targets—including the Kaip and Williams East zones—are located along the margins of this breccia, where porphyry-style mineralization may exist. The deep chargeability anomaly targeted in these holes remains unexplained, and additional work is planned.

Drilling Challenges at Upper Hank

At the Upper Hank porphyry target, hole HW-25-005 was abandoned at 280 meters, short of the intended 800-meter depth, due to drilling difficulties. The hole cut through a mapped pyrite-rich breccia and encountered two narrow porphyry intrusions showing mineral textures similar to those observed at Williams. A re-drill of this target, HW-25-006, is currently underway to test the deeper chargeability anomaly.

Lower Hank Drilling Continues

Hole HW-25-007 is actively drilling the Lower Hank porphyry target. The drill is planned to intersect a steep quartz-sericite-pyrite-carbonate body mapped at surface, which contains more than 5% pyrite to a depth of approximately 200 meters. The targeted mineralization is associated with a broad, low-angle plunging zone of copper-gold-silver mineralization intersected in historical drilling. Below 250 meters, the drill will test a strong chargeability anomaly (>25 mV/V) for the presence of a deeper porphyry system at a comparable elevation to Williams.

Regional Exploration Activities Underway

In addition to drilling, regional geophysical and geochemical surveys are advancing. An airborne magnetotelluric (MMT) survey is approximately 65% complete. Induced polarization (IP) crews began work on July 26, focusing on the Hank-Williams-Mary trend.

A soil sampling campaign was recently completed, collecting over 750 samples. The program aimed to address gaps in historical soil coverage, especially between the Hank-Williams corridor and the Mary-ME zone. Additional sampling was conducted northeast of the Mary and ME targets, and within a valley southeast of Hank and ME.
