Copper Fox Provides Results of 3D Swath Dcip & MT Surveys ON Sombrero Butte Porphyry Copper Project
COPPER FOX PROVIDES RESULTS OF 3D SWATH DCIP & MT SURVEYS ON
SOMBRERO BUTTE PORPHYRY COPPER PROJECT
Calgary, Alberta – February 18, 2025. Copper Fox Metals Inc. (“Copper Fox” or the “Company”)
(TSXV:CUU | OTCQX:CPFXF | FRA:HPU) and its 100% owned subsidiary, Desert Fox Sombrero
Butte Co. (“Desert Fox ”), are pleased to provide the results of the recently completed chargeability/
resistivity (DCIP) and magnetotelluric (MT) geophysical surveys (see news release dated December 19,
2024) on the Sombrero Butte projec t. The Sombrero Butte project is located approximately three
kilometers south of the Copper Creek porphyry copper deposit.
Elmer B. Stewart, President & CEO 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 meters (m) 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
sulfide minerals like pyrite and chalcopyrite. Resistivity data is used to interpret various alteration patterns
associated with porphyry copper systems.
Geophysical Surveys
The 2024 geophysical program consisted of a deep 3D SWATH DCIP & MT survey. The chargeability
data presented in this news release utilized the HS (half-space) reference for modelling purposes. The
+25 mrad (12 mV/V) chargeability contour has been selected for the threshold of anomalous chargeability.
Chargeability values recorded during the survey ranged from nil to greater than 80 mrad (38 mV/V) and
resistivity values range d from 30 ohm-m to greater than 10,000 ohm -m. Mapping of the subsurface
chargeability and resistivity signatures to depth of 800 m below surface were performed. The
chargeability anomaly (+25 mrad) is enclosed within a much larger zone of +15 mrad chargeability. The
location and dimensions of anomalous chargeability at selected depths below surface are shown in the
figures below.

projected to surface draped on surface topography.
At surface, (approximately 1,400 m 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 m below surface the chargeability anomaly measures approximately 3,200 m long by 1,300 m
wide whereas at a depth of 450 m below surface the chargeability anomaly measures approximately 1,900
m long by 1,100 m wide. At a depth of approximately 800 m 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 m.

MT Survey
The MT survey measured resistivity to depths of more than 2,000 m below surface. The data was modelled
in 2D and shows a good correlation to the shallower chargeability (0 to 800 m below surface) and
resistivity data collected by the DCIP survey.

Geophysical Survey Procedures
The 3D SWATH DCIP & 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 m apart with station spacing of 100 m along the survey lines.
For the purposes of this preliminary interpretation, anomalous chargeability is defined as greater than 25
mrads. The survey covered an area of approximately 3,200 m by 2,400 m. Both 2D and 3D modelling of
the DCIP data were carried out using the UBC DCIP2D inversion codes (Oldenburg and Li, 1994) to
produce depth sections of DC resistivity, DC -referenced IP chargeability and HS -referenced IP
chargeability to a depth of investigation of between 750 m to 800 m. The 3D inversion of the DCIP data
was completed using the UBC 3D inversion codes (Li and Oldenburg, 2000). The full set of 3D Tx-Rx
measurements were merged into a single data set and modeled in 3D to produce 3D resistivity and DC -
referenced chargeability models. Results of the MT data were modelled in 2D.
