Canadian Copper Inc. Announces Feasibility Study Team Award and Project Update

Toronto, May 27, 2026 - Canadian Copper Inc. (CSE: CCI) ("Canadian Copper" or the "Company") today announced that it has awarded the Feasibility Study ("FS") for the combined 100%-owned Murray Brook Project and Caribou Process Plant to DRA Americas as lead author, SLR Consulting Ltd., Stantec Consulting Ltd., and Dillon Consulting Limited. The current timeline to publish results from the FS is December 2026. The study team and contributing consultants were selected based on several elements including their previous experience with the Caribou Process Plant, their study team proximity to the project and distance from identified key contractors for the project execution, and timely delivery schedule.

Project Update

• Early works site activities have commenced at Murray Brook in support of the FS, including:
  • Geotechnical investigations (Image A) for site infrastructure design parameters at Murray Brook (waste dump facilities, modular buildings, and haul road design).
  • Additional sample collection targeting waste, ore, and topsoil for kinetic testing in support of environmental characterization, water treatment, final mine design, and closure plan.
• Haul road design between Murray Brook and Caribou site is progressing:
  • Optimization and trade-off studies underway to re-develop existing logging roads to minimize impact, cost, while reviewing expected route gradient to minimize operating costs.
• Site-wide water management at Murray Brook field activities will start in July, including:
  • Simulated flows for main Murray Brook design facilities (open pit, waste dumps, modular facilities, and catchment ponds).
  • Deterministic water quality modeling.
  • Predictive groundwater modeling with hydraulic conductivity and additional monitoring well installations.
• Metallurgical testwork at SGS Canada Inc. ("SGS") in Lakefield, Ontario continues to advance.
  • SGS has completed 26 rougher and open-circuit cleaner tests to date and expects to begin closed-circuit locked cycle testing this month.
  • Results from the SGS testwork will be included into the FS to finalize the flowsheet design, estimate process plant operating costs, and predict recovery performance.
• The Company remains on track to register the Environmental Impact Assessment ("EIA") with the New Brunswick Department of Environment and Local Government ("DELG") in the H1 of 2026.
  • Draft Project Description is complete and under review.
  • The Company engineering teams continue to advance key project design components. As design deliverables are received, updates will be provided to DELG to support regulatory review of the EIA.

Christian Brousseau, Vice President, Projects of Canadian Copper, stated, "We have assembled a dynamic team and their contributions will be essential in developing this project. The opportunity of re-using existing infrastructure is a significant advantage in cost and schedule, but also on the permitting front. Revitalizing this complex and extending its life for +13 years will have a meaningful and immediate impact on the region."

The Company, as buyer, and FTI Consulting Canada Inc. ("FTI"), the court appointed Receiver of Trevali Mining New Brunswick Ltd., and the New Brunswick Government continue to advance the closing of the Caribou Complex transaction. The current timeline remains Q2, 2026.
