Copper Fox Assembles Project Team to Explore Advancing Van Dyke Iscr Project to Prefeasibility Study Stage

Corporate Updates

COPPER FOX ASSEMBLES PROJECT TEAM TO EXPLORE ADVANCING

VAN DYKE ISCR PROJECT TO PREFEASIBILITY STUDY STAGE

Calgary, Alberta – June 23, 2025, Copper Fox Metals Inc. (“Copper Fox” or the “Company”) (TSXV:CUU |

OTCQX:CPFXF | FSE:HPU), through its wholly owned subsidiary Desert Fox Van Dyke Co ., is pleased to

provide an update on its 100% owned Van Dyke in-situ copper recovery (ISCR) project located in the Globe-Miami

Mining District, Gila County, Arizona.

In 202 0, Copper Fox completed an updated Mineral Resource Estimate (MRE) and Preliminary Economic

Assessment (PEA) on Van Dyke using a US$3.15/lb copper price for the base case economic model. The critical

need for copper, the potential social and financial benefit to the Town of Miami and surrounding communities

support Copper Fox’s decision to prepare an Execution Plan to advance Van Dyke to the Prefeasibility Study (PFS)

stage. Among other findings, the PEA indicated:

i. project sensitivity to copper prices such that a US$0.25/lb. increase in copper price increased the after-tax

NPV by approximately US$90 million,

ii. significant exploration potential to increase the project’s mineral resources, and

iii. recommendation to advance the project to the PFS stage.

Elmer B. Stewart, President and CEO of Copper Fox, stated, “We are pleased to have assembled this team of mining

professionals led by Stantec, a global leader in surface and underground mining engineering, design, and project

delivery, to assist Copper Fox in preparing an Execution Plan to complete a PFS level study on the Van Dyke

project. These firms bring a vast amount of knowledge to the Van Dyke project based on their work experience on

two other advanced-stage ISCR projects in Arizona. Copper Fox is adopting a phased approach to the PFS, the first

step being preparation of the Execution Plan that maps out the scope, timing and estimated cost of the various

programs and studies required to meet the threshold of a PFS level study. The information gained from completing

this Execution Plan will assist the Board on decision making regarding progressing to the PFS stage for Van Dyke.”

Nick Hynd, Stantec Project Manager in Phoenix, added, “The Van Dyke project will produce much-needed copper

in a safe and environmentally sound manner while providing hundreds of jobs for the Miami-Globe area. Stantec

is proud to support Copper Fox in advancing this exciting project that will benefit the state of Arizona.”

Metallurgical Modelling

Samuel Engineering has commenced the preparation of a preliminary geometallurgical model of the Van Dyke

project. The modelling, using Cancha Geometallurgy software, is expected to provide a better understanding of the

variability and distribution of the soluble copper mineralogy, identify geometallurgical domains and identify “gaps”

in the current sample distribution across the deposit. Identification of the gaps allows Samuel to pre -select

representative sample locations from the mineralogical zones within the Van Dyke deposit from future drillholes to

support an updated geometallurgical model and better predict future copper production.
