Copper Fox Announces Porphyry Copper Discovery and Strong Vectors Toward Core at Mineral Mountain
Copper Fox’s Mineral Mountain drilling confirms a deep porphyry core while the company’s cash runway remains tight amid steady operational burn rates.

Executive Summary
- Copper Fox Metals released preliminary results from diamond drillhole DDH MM-02-2025 at its 100% owned Mineral Mountain project in Arizona.
- The hole intersected a large, evolved porphyry copper-molybdenum system, terminating early at 1,697.35m due to drilling conditions, leaving the system open at depth.
- Analytical results show grades increasing downhole, with strong geological vectoring indicators toward a higher-grade potassic core.
- Key intercepts include 896m–1,394m averaging 0.203% Cu and 0.051% Mo, with a high-grade sub-interval (1,365m–1,394m) returning up to 2,032 ppm Cu and 515 ppm Mo.
- Alteration sequences display classic potassic overprinting by propylitic and phyllic zones, with increasing pyrite, coarse sericite, and quartz veining at depth.
- Management plans to re-enter the hole to deepen below 1,700m and conduct step-out drilling, alongside locating six new mineral claims to cover the extension.
Material Impact
- The results are positive and validate the initial discovery from DDH MM-01-2025 (April 2026), confirming a classic porphyry alteration and mineralization sequence.
- However, this is an expected follow-up to the maiden drilling program announced in October 2025. No new resource estimate, economic study, or financing was disclosed.
- The market likely already priced in the initial discovery; this update provides incremental geological confidence but does not alter the near-term investment thesis.
- Prior-period context — not disclosed in today's release: The company reported a Q1 2026 net loss of $242,857 and held $1.31M in cash as of January 31, 2026, following a $3M private placement.
