Copper Fox Provides Update on 2025 Geophysical Program on Eaglehead Porphyry Copper Property

Rhea-AI Summary

Copper Fox (OTCQX: CPFXF) reported results of its 2025 geophysical program at the 100%‑owned Eaglehead porphyry copper project on November 19, 2025. The survey outlined an open-ended northwest‑trending chargeability anomaly ~4,400 m long with ~1,000 m width at 250 m depth in the East deposit widening to ~2,000 m in the Camp deposit, and the anomaly remains open to the northwest.

The program identified pipe‑like chargeability bodies connected to surface, confirmed spatial correlation with four porphyry deposits from the 2023 MRE, and flagged a 1,500 m target area between Camp and the West zone. A 500 m drill gap between East and Bornite is a priority for future drilling; a desktop access study is underway.

Positive

• Anomalous chargeability corridor extended to ~4,400 m length
• Chargeability width ~1,000 m (East) to ~2,000 m (Camp) at 250 m depth
• Identified pipe‑like chargeability bodies linking mineralization to surface
• New 1,500 m target area between Camp deposit and West zone

Negative

• 500 m drill coverage gap between East and Bornite requires new access
• Open‑ended anomalies require follow‑up drilling to confirm resource extensions

Calgary, Alberta--(Newsfile Corp. - November 19, 2025) - Copper Fox Metals Inc. (TSXV: CUU) (OTCQX: CPFXF) (FSE: HPU) ("Copper Fox" or the "Company"), through its wholly owned subsidiary Northern Fox Copper Inc. ("Northern Fox"), is pleased to provide the results of the 2025 geophysical program and the desktop studies that are underway to support future drilling programs at its 100% owned Eaglehead porphyry copper project (see news release dated August 22, 2025).

Highlights of the 2025 Geophysical Program

• Outlined an open-ended, northwest trending, north dipping zone of anomalous chargeability and associated low resistivity measuring approximately 4,400 meters (m) long.
• At the 250m level below surface, the chargeability anomaly measures approximately 1,000m wide in the East deposit and increases to 2,000m wide in the Camp deposit. The chargeability anomaly is open to the northwest past the Camp deposit.
• The four deposits (East, Bornite, Pass, Camp) of porphyry mineralization outlined in the 2023 Mineral Resource Estimate (MRE), NI 43-101 Mineral Resource Estimate of the Eaglehead Project, submitted by Moose Mountain Technical Services, Sue Bird, P.Eng. with an effective date of August 21, 2023, (see news release dated August 30, 2023) are located along the apex of the chargeability anomaly within the "mineralized corridor".
• The program identified several pipe-like bodies of anomalous chargeability extending from the main chargeability body to surface that show a strong spatial correlation to leached, mineralized hydrothermal breccia and areas of copper showings exposed in outcrop.

Elmer B. Stewart, President and CEO of Copper Fox, stated, "The 2025 geophysical program substantially expanded the anomalous chargeability and resistivity signatures associated with the four deposits of porphyry copper-gold-molybdenum-silver mineralization located within the mineralized corridor. The program highlights the potential to expand the mineralization in the East, Bornite, Pass and Camp deposits and draws attention to the extension of the chargeability and resistivities to the northwest portion of the project located between the Camp deposit and the West zone. This area is now a priority target for future exploration. To accommodate future drilling plans a desktop study assessing potential options to provide access to proposed drillhole locations situated between the East and Bornite deposits is in progress."

A compilation of the 2025 geophysical data acquisition program and merging of the chargeability and resistivity datasets for the 2014, 2021, and 2025 geophysical surveys is presented in Figure-1. The 7mv/s (15mrad) chargeability signature was selected to define anomalous chargeability in line with the 15mrad signature used in the 2014 and 2021 geophysical programs. Distances indicated in this news release are approximate.

The 2025 geophysical survey outlined anomalous chargeability surrounding the four open-ended porphyry deposits established in the 2023 MRE. The MRE established a strong spatial correlation between porphyry mineralization and anomalous chargeability and concluded that the mineralization contained within these deposits represents the upper levels of the porphyry mineralization. Of the four porphyry deposits, the East and the Bornite deposits are better understood and provide an example of the open-ended nature of these deposits.

The mineralized intervals supported by resource modelling and anomalous chargeability show that the mineralization in the East deposit is open to the south. The weighted average grade of selected mineralized intervals in drill holes on the south edge of the East deposit is shown in Table-1 below.

DDH ID	From (m)	To (m)	Int. (m)	Cu (%)	Mo (%)	Au (g/t)	Ag (g/t)
84	130.30	340.00	209.70	0.354	0.020	0.086	0.65
86	114.91	453.24	338.33	0.329	0.030	0.076	0.48
92	356.01	441.96	85.95	0.343	0.020	0.094	0.48

Similarly, for the Bornite deposit the mineralized intervals supported by resource modelling and the anomalous chargeability show that the mineralization in the Bornite deposit is open to the north. The weighted average grade of selected mineralized intervals in drill holes on the north edge of the Bornite deposit are shown in Table-2 below.

DDH ID	From (m)	To (m)	Int (m)	Cu %	Mo (%)	Au (g/t)	Ag (g/t)
111	59.00	101.00	42.00	0.748	0.003	0.195	5.29
112	70.00	178.00	108.00	0.386	0.007	0.193	3.43
114	130.00	296.00	166.00	0.533	0.029	0.294	2.07
116	140.00	251.00	111.00	0.483	0.020	0.276	1.40
120	29.00	106.00	77.00	0.369	0.008	0.091	0.86

The significant increase in size of the anomalous chargeability demonstrates the potential to extend the mineralization in all four deposits to the north and south and continuity of the mineralization between these deposits. The abrupt termination of the chargeability at the east end of the East deposit is consistent with the current geological, alteration and mineral resource models for the East deposit. The 2025 program also highlighted the previously unrecognized mineral potential of the Camp deposit and the 1,500m long area between the Camp deposit and the West zone, a previously defined area of porphyry style mineralization. The drillhole collar locations used in this news release are shown in Table-3 below.

Desktop Study
The 500m long gap in the drillhole coverage between the East and Bornite deposits is a priority area for future drilling. Positive results from drilling in this area potentially expands the project resource and provides greater certainty on the geometry of the mineralization. Geological modelling indicates the drilling completed to date may have been parallel or sub-parallel to the dip of the mineralized quartz veins and fractures as suggested by surface measurements of these mineralized structures.

The proposed area for drilling is located north of a small stream, and the desktop study is being completed to assess options to establish long term access to the area on the north side of the stream, minimize the environmental disturbance and significantly reduce costs related to drill moves.

About the Eaglehead Project
The Eaglehead project covers an intrusion hosted calc-alkalic polymetallic (Cu-Mo-Au-Ag) porphyry copper system (i.e. like the porphyry deposits in the Highland Valley district of BC) located in the prolific Quesnel Terrain approximately 50 kilometers (km) east of Dease Lake, BC. The property covers 15,713 ha centered over the Late Triassic-Early Jurassic (195Ma) granodioritic/dioritic Eaglehead batholith. The exploration target is an 8km by 3km zone of altered and mineralized rocks located along the southern margin of the batholith referred to as the "mineralized corridor" that hosts four open-ended deposits and two large zones of porphyry style copper-molybdenum-gold-silver mineralization and associated alteration located along the apex of an open-ended chargeability anomaly.

Survey specification for the 2025 geophysical survey and merging the geophysical data sets from the 2014, 2021 and 2025 geophysical surveys have been set out in several news releases (see news release dated July 16, 2025).
