COPPER FOX ANNOUNCES 2023 EXPLORATION PLANS FOR

MINERAL MOUNTAIN COPPER PROJECT

Calgary, Alberta– March 30, 2023. Copper Fox Metals Inc. (“Copper Fox” or the “Company”) (TSXV:CUU

– OTCQX:CPFXF) and its wholly owned subsidiary, Desert Fox Copper Inc. (“ Desert Fox”), are pleased to

announce that they have executed a contract with Quantec Geosciences USA Inc. to conduct a deep penetrating

geophysical survey on its 100% owned Mineral Mountain project located approximately 25 kilometers (‘km’) (15

miles) east of Florence, Arizona. The geophysical survey will employ Quantec’s ORION 3D Swath DCIP

configuration. Highlights of the survey are set out below:

Highlights

• The objective of the survey is to further define the horizontal and depth extensions of the open-ended

chargeability and resistivity signatures associated with the 4,500 meter (‘m’) long by 2,000 m wide

copper “footprint”.

• Detailed mapping of lithology, alteration and mineralization along the proposed geophysical survey

lines is planned to better interpret the results of the geophysical survey.

• The survey is to commence in May 2023 and may vary subject to crew availability.

• Geochemical vectoring (Cu/Zn ratio) defined a 4,000 m long northeast-southwest trending corridor

potentially hosting two additional porphyry targets on strike with the mineralized Laramide age

intrusive.

Elmer B. Stewart, President, and CEO of Copper Fox, stated, “The planned ORION 3D Swath DCIP survey has

been used at ou r advanced exploration stage Eaglehead copper-gold-molybdenum porphyry project in northern

British Columbia with considerable success. Mineral Mountain is a Laramide age porphyry copper-molybdenum

system with enriched gold concentrations like several porphyry system s in the Safford mining district in

southeastern Arizona with potential to locate several additional porphyry centers on strike with the mineralized

Laramide age intrusive.”

Geological Model

Mineral Mountain is a copper (gold-molybdenum) rich porphyry system characterized by a strong copper-magnetite

association that was subjected to several episodes of weathering/oxidization commonly seen in porphyry copper

systems in Arizona . The Cu-Au-Mo mineralization is hosted in mineralized and non -mineralized, porphyritic

granodioritic and quartz monzonitic phases of the Laramide age intrusive (69.7 +/- 0.4 Ma; U/Pb zircon) . The

porphyry style mineralization is associated with strong Potassic alteration (K-Spar-biotite-magnetite) and Sericitic

(sericitic-chlorite +/-actinolite) alteration. Propylitic (epidote + chlorite) is peripheral to mineralization and in

places overprints the Potassic and Sericitic alteration evidenced by copper-epidote veining. The mineralization,

alteration and the open-ended positive chargeability signature/resistivity signature identified in 2021 show a strong

spatial correlation to several late-stage, pipe-like, intrusives within the Laramide intrusive with positive magnetic

signatures attributed to early stage Potassic alteration.

2023 Geophysical Survey

The objective of the planned 50.5 km survey (see Image #1) is to map the chargeability and resistivity signatures

of the porphyry mineralization and associated alteration patterns located within the multi -phase Laramide age

intrusive. Utilizing the ORION 3D SWATH DCIP survey, configuration is expected to provide a better definition

of the thickness of the surface weathering/oxidization profile, expand the limits of the chargeability and resistivity

signature outlined in 2021 and map the two additional porphyry targets identified by the Cu/Zn ratio modelling.

Geochemical Vectoring

Porphyry copper deposits exhibit metal zonation patterns grading from copper mineralization at the core (proximal)

outward to base metal mineralization (distal) toward the edge of the porphyry system. The Cu/Zn ratio is commonly

used to indicate proximity to the center of a porphyry system. The Cu/Zn ratio (based on 500 samples) for the

Mineral Mountain project identified a structurally controlled northeast Cu/Zn trend (see Image #2) consistent with

the copper mineralization, alteration patterns and interpreted late-stage intrusive activity. The areas exhibiting a

Cu/Zn ratio greater than 50 exhibit a strong spatial association to the known copper occurrences within Laramide

age intrusive and suggests the potential for additional porphyry centers within the Mineral Mountain project.

identified areas may be larger than actual due to extrapolation of values by the Micromine modelling software.
