Copper Fox reviews geophysical program at Eaglehead

Executive Summary

• Copper Fox completed a 3‑D pole‑dipole DCIP survey at Eaglehead, revealing a 2.8 km long surface chargeability anomaly that extends ~2.4 km down‑dip northward.
• The newly mapped anomaly correlates strongly with known porphyry copper mineralization and expands the target area, suggesting a larger potential mineralized envelope than indicated in the 2023 Mineral Resource Estimate (MRE).
• Copper Fox will merge 2014–2025 geophysical data to refine chargeability and resistivity models over a ~5 km × 4 km area, guiding future drilling programs.

Key Details

• Survey Scope: 19.7 line‑kilometres acquired in 14 days (11 days acquisition, 3 days layout); ground/wire length 21.2 km; conducted with DIAS 32 distributed array system.
• Anomalous Chargeability:
• Surface zone 2,800 m long, >8 mV/s (~17 mrads) contour.
• Extends down‑dip ~2,400 m to the north under propylitic altered quartz‑eye porphyry.
• Several pipe‑like bodies correspond to leached hydrothermal breccia and secondary copper showings mapped at surface.
• Correlation: The 2025 anomaly aligns with the 2014 chargeability signature and the four porphyry zones defined in the 2023 MRE (East, Bornite, Pass, Camp).
• Implications: Expanded chargeability suggests a larger biotite granodiorite host and potentially greater mineralized volume; supports view that current drilling intercepts only the upper portion of the system.
• Future Work:
• DIAS contracted to integrate 2014–2025 data into updated chargeability and resistivity sections/plan maps covering ~5 km × 4 km.
• Data will be used to better delineate intrusive phases, alteration zones, and guide the next phase of drilling at Eaglehead.
• Project Context: Eaglehead is a 15,713‑ha porphyry copper‑molybdenum‑gold‑silver system in the Quesnel terrain, BC, with an eight km × 3 km mineralized corridor hosting four open‑ended deposits and two large zones of porphyry style mineralization.

Notable Quotes

• “The preliminary results of the 2025 survey significantly expanded the anomalous chargeability associated with the porphyry copper mineralization… The strong correlation between chargeability and porphyry mineralization combined with the expanded chargeability target has significant implications for the potential size of the mineralized envelopes…” – Elmer B.
