Copper Fox Commences PEA and Groundwater Flow Modeling to Support Future Permitting at Van Dyke Iscr Project

Corporate Updates

COPPER FOX COMMENCES PEA AND GROUNDWATER FLOW MODELING

TO SUPPORT FUTURE PERMITTING AT VAN DYKE ISCR PROJECT

Calgary, Alberta – February 12, 2026. 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 the planned preliminary economic assessment (PEA) and

groundwater flow model on its 100% owned Van Dyke in-situ copper recovery (ISCR) project located in

the Globe-Miami Mining District, Gila County, Arizona, approximately 90 miles east of the recently

commissioned Florence Copper project.

The Van Dyke ISCR project is recognized as a potential near term, mid -size, environmentally friendly,

sustainable copper project with a 17 -year mine life and a production capacity of 85 million pounds of

Grade A 99.99% pure copper cathode per year . Based on the previous PEA completed in 2020 (“NI 43-

101 Preliminary Economic Assessment Technical Report for the Van Dyke Copper Project”, effective date

December 30, 2020, prepared by Susan C. Bird, MSc., P.Eng., Bob Lane, P.Geo., and Tracey Meintjes,

P.Eng., of Moose Mountain Technical Services and Jim Norine, P.E., of Ausenco Limite d), the project is

expected to provide approximately 500 direct and indirect jobs in the Miami -Globe area , inject

approximately US$1.07B into Arizona economies and contribute approximately US$355M in mineral,

state and federal taxes over its mine life. The project has significant resource expansion potential and

benefits from access to local infrastructure that includes a copper rod plant, highways, rail lines, and

electrical power.

Activities

• Preparation for the 2026 PEA has commenced and is estimated to cost C$300,000.

• Preparation of a preliminary semi-regional 3-D numerical groundwater flow model is underway,

results of which are expected to be included in the PEA.

• Daily collection of h ydrogeological data and quarterly groundwater sampling from the existing

four monitoring wells to augment the project’s hydrogeological and water quality database and

support future permitting is ongoing.

Elmer B. Stewart, President and CEO of Copper Fox, stated, “ Our focus in the first half of 2026 is

completion of an updated PEA. The PEA is focused on establishing the current technical understanding

of the project , optimizing the 2025 PFS Execution Plan and outlining the environmental permitting

required to complete activities identified in the PEA. The permitting for development stage projects

includes an Aquifer Protection Permit (APP) and Underground Injection Control (UIC) permit and key

steps in obtaining these permits includes developing a robust, calibrated hydrogeological model to

demonstrate to stakeholders and regulatory agencies that the hydrogeology and groundwater quality of the

project and area surrounding the project is well understood, potential impacts have been evaluated, and

that appropriate monitoring and mitigation would be included in a future mine operating plan.”

Updated PEA

Copper Fox has commissioned Moose Mountain Technical Services to prepare an updated PEA on the

Van Dyke copper project in accordance with the Canadian disclosure requirements of National Instrument

2

43-101 – Standards and Disclosures for Mineral Projects (NI 43 -101) and the requirements of Form 43 -

101F1.

Preliminary Groundwater Flow Model

RGC Hydro Services LLC has been contracted to prepare a preliminary semi -regional 3-D numerical

groundwater flow model for the Van Dyke project (and greater Miami area) using project and

hydrogeological data from the area surrounding the project. Updating the model is planned as additional

hydrogeological data becomes available.

The model is expected to locate hydrogeological and water quality monitoring wells in subsequent drilling

programs and can be used to simulate mine development, predict hydrogeologic impacts, support the

design and construction of monitoring and mitigation systems , placement of monitoring wells and is

expected to play a prominent role in a future permitting strategy. As the project advances, the model can

be used as a tool for running operational scenarios, looking at well spacing, sweep efficiency estimations,

wellfield optimization , to characterize baseline groundwater conditions and define site -specific water

quality conditions for permitting, such as alert levels (ALs) and aquifer quality limits (AQLs).

Modeling Objectives

• Describe the extent of the local and regional groundwater systems around the Van Dyke deposit.

• Define the mine-scale geologic and structural controls that may bound and limit hydrogeologic

interaction with the regional hydrologic system and define possible mechanisms for hydrologic

interconnection.

• Predict local and broader scale hydrologic features that may potentially become impacted by the

mine development and dewatering.

• Demonstrate with reasonable confidence the areas of the regional groundwater system that will

be unimpacted by the mine project.

• Provide a preliminary basis for negotiating a reasonable hydrologic monitoring and mitigation

plan as part of the future permitting process.

• Provide support for Arizona Department of Environmental Quality Aquifer Protection and

Underground Injection Control permitting processes, as well as discussions with Pinal Creek

Group and other stakeholders.
