Copper Fox Metals Inc. has intercepted significant copper-molybdenum mineralization within a 278.97-metre interval in diamond drillhole MM-02-2025 at its Mineral Mountain project in Arizona. The hole, which reached a total depth of 1,697.35 metres, was designed to test a large surface porphyry footprint and an underlying chargeability anomaly.

Analytical results from the programme demonstrate multiple phases of mineralisation and alteration. A notable core interval from 1,469.89 metres to 1,657.97 metres returned 188.08 metres at an average grade of 0.189% copper and 0.019% molybdenum. Within this section, the company intersected an eight-metre sub-interval from 1,541 metres to 1,549 metres grading 0.709% copper and 0.052% molybdenum.

The drillhole encountered geological features typical of porphyry systems, including cross-cutting sulphide vein assemblages, magnetite sulphidization, and the appearance of bornite rimming chalcopyrite at depth. The company suggests that these features, combined with the observed alteration patterns, indicate the drillhole did not reach the core of the porphyry system.

“The concentrations of copper-molybdenum intersected in the lower portion of DDH MM-02-2025 are comparable to and within the range of copper-molybdenum grades seen in other Laramide age porphyry deposits in Arizona.”

Copper Fox interprets the presence of these porphyry indicators as evidence that the system's "potassic core"—the hotter, central part of the system—may be located at greater depth.

To refine its geological model prior to planning further drilling, the company is preparing to perform additional core sampling. This effort will be supported by a comprehensive technical review incorporating all structural, geological, geochemical, and geophysical data. This review will employ geochemical vectoring techniques to map trace element, mineral, and alteration patterns. By identifying the transition from high to lower temperatures, the company aims to better define the geometry of the system, using indicators such as bismuth and molybdenum to map the potential core, and antimony and arsenic to identify the cooler margins.

The two-hole 2025 maiden drill programme, totalling 2,558.11 metres, has now concluded. The initial hole, MM-01-2025, previously intersected eight intervals of copper-molybdenum enrichment in the outer portions of the system. Future work will focus on integrating these latest findings to guide subsequent exploration steps.
