Canadian Copper Provides Murray Brook Project Update

Toronto, November 18^th, 2025 – Canadian Copper Inc. (CSE:CCI) (“Canadian Copper” or the “Company”) announced today several updates regarding its Murray Brook Project including the on-going metallurgical program, permitting activities, and the project financing status.

Metallurgical Program Update

The metallurgical testwork program was awarded to SGS Canada Inc. (“SGS”) in Lakefield, Ontario on November 11^th, 2025. This testwork is designed to further refine process plant operating costs and recovery performance as outlined in the 2025 Preliminary Economic Assessment (“PEA”) “next steps”. Further, the objective of these flotation tests is to simulate the planned plant flowsheet as outlined in the PEA.

Approximately 3,100 kilograms from fresh diamond drill cores totaling about 244 meters of material was selected from the 1,000 meter drill program completed (see Photo A). It comprised 10 new drill holes targeting the initial phases of the mine design (see Photo B). Samples are in transit to SGS for assay preparation and testing. Examples of the massive sulphide intervals intersected include pyrite, chalcopyrite (copper), and sphalerite (zinc) sulphides (see Photo C1 – C2).

To ensure desired grades were collected for SGS’ eventual composites preparation, the Company twinned historical holes drilled between 2012-2013. Based on the visual logging of the 2025 cores obtained from drilling, the geologic and resource model reconciled well.

Permitting Update

The Company first engaged the Technical Review Committee (“TRC”), which is comprised of provincial and federal departments, in July 2025 to discuss the Combined Strategy. The objective of this engagement is to share the project details early and understand TRC questions prior to Environmental Impact Assessment (“EIA”) registration in H1 2026. The Company is preparing answers to questions received from the TRC related to emissions sources and water management infrastructure now.

Baseline environmental data collection programs to support the EIA registration are complete for the 2025 field season. These programs included field work relating to archaeology, fish habitat, avian and other wildlife species, vegetation and wetlands. Desktop studies related to surface water and groundwater, air quality and climate are currently underway. Technical data reports for these field programs and desktop studies are being completed now and will be incorporated into the EIA registration document, with expected delivery in H1, 2026.

Funding Strategy Update

The Company is advancing several project funding discussions. The objective is to secure capital for both the required pre-development steps (design, permitting, early works, team formation) and the project construction capital. We expect to select our path and partners in H1, 2026. In parallel, the Company will engage various government sources through Natural Resources Canada (“NRCan”) and their Critical Minerals Infrastructure Fund (“CMIF”), as-well as new programs underway based on the 2025 Federal Budget.
