COPPER FOX PROVIDES RESULTS OF 3D SWATH DCIP & MT SURVEYS ON SOMBRERO BUTTE PORPHYRY COPPER PROJECT

Copper Fox Metals Inc. and its 100-per-cent-owned subsidiary, Desert Fox Sombrero Butte Co., have provided the results of the recently completed chargeability/resistivity (DCIP) and magnetotelluric (MT) geophysical surveys (see news release dated Dec. 19, 2024) on the Sombrero Butte project. The Sombrero Butte project is located approximately three kilometres south of the Copper Creek porphyry copper deposit.

Elmer B. Stewart, president and chief executive officer of Copper Fox, commented: "The geophysical program has mapped a large north-northwest-trending body of anomalous chargeability that in places extends from surface to depths exceeding 800 metres located along the interpreted Copper Creek granodiorite/Glory Hole volcanic contact. At surface, the chargeability anomaly exhibits a strong spatial correlation with the large zone of moderate-to-intense limonite (after pyrite) alteration/staining that has been mapped within the Laramide-age Glory Hole volcanics. The chargeability signature is interpreted to represent the potential of a large body of sulphide mineralization at depth and further supports the potential for a porphyry copper system underlying the Sombrero Butte project."

Geophysical exploration/porphyry copper deposits

In porphyry copper exploration, anomalous chargeability signatures are typically interpreted to indicate zones of potential mineralization by showing high-chargeability values associated with disseminated sulphide minerals such as pyrite and chalcopyrite. Resistivity data are used to interpret various alteration patterns associated with porphyry copper systems.

Geophysical surveys

The 2024 geophysical program consisted of a deep 3-D Swath DCIP and MT survey. The chargeability data presented in this news release utilized the HS (half-space) reference for modelling purposes. The greater-than-25-milliradian (12-millivolt-per-volt) chargeability contour has been selected for the threshold of anomalous chargeability. Chargeability values recorded during the survey ranged from nil to greater than 80 milliradians (38 millivolts per volt) and resistivity values ranged from 30 ohm-metres to greater than 10,000 ohm-metres. Mapping of the subsurface chargeability and resistivity signatures to depth of 800 metres below surface were performed. The chargeability anomaly (greater than 25 milliradians) is enclosed within a much larger zone of greater-than-15-milliradian chargeability.

At surface (approximately 1,400 metres above sea level), the majority of the chargeability anomaly is located within the Laramide-age Glory Hole volcanics and shows a strong spatial correlation to a laterally extensive zone of moderate to intense limonite alteration/staining.

At 200 metres below surface, the chargeability anomaly measures approximately 3,200 metres long by 1,300 metres wide, whereas, at a depth of 450 metres below surface, the chargeability anomaly measures approximately 1,900 metres long by 1,100 metres wide. At a depth of approximately 800 metres below surface, the chargeability anomaly splits into two smaller zones (root zones) that decrease in size downward to the depth penetration limits of the survey. Interpretation of the MT resistivity data suggests that the chargeability anomaly continues at depth below 800 metres.

MT survey

The MT survey measured resistivity to depths of more than 2,000 metres below surface. The data were modelled in 2-D and show a good correlation to the shallower chargeability (zero to 800 metres below surface) and resistivity data collected by the DCIP survey.

Geophysical survey procedures

The 3-D Swath DCIP and MT survey completed by Quantec Geoscience USA Inc. covers the entire Laramide-age Copper Creek granodiorite and Glory Hole volcanics area within the Sombrero Butte project. The survey measured, employing a pole-dipole-dipole array configuration, the DCIP signal on seven north-south-oriented lines spaced 400 metres apart with station spacing of 100 metres along the survey lines. For the purposes of this preliminary interpretation, anomalous chargeability is defined as greater than 25 milliradians. The survey covered an area of approximately 3,200 metres by 2,400 metres. Both 2-D and 3-D modelling of the DCIP data were carried out using the UBC DCIP2D inversion codes (Oldenburg and Li, 1994) to produce depth sections of DC (direct current) resistivity, DC-referenced IP chargeability and HS-referenced IP chargeability to a depth of investigation of between 750 metres to 800 metres. The 3-D inversion of the DCIP data was completed using the UBC 3-D inversion codes (Li and Oldenburg, 2000). The full set of 3-D Tx-Rx measurements were merged into a single data set and modelled in 3-D to produce 3-D resistivity and DC-referenced chargeability models. Results of the MT data were modelled in 2-D.
