CASCADE COPPER ANNOUNCES RESULTS FROM FIELD WORK AT THE CENTREFIRE COPPER-GOLD PROJECT RESULTS INCLUDE 2.86% CU, 2.84 G/T AU AND 15.7 G/T AG

Cascade Copper Corp. has received assay results from the first batch of samples from a field program of ground truthing geophysical anomalies and rock sampling at its Centrefire copper and gold project located approximately 40 kilometres northeast of Dryden, Ont., Canada. The fieldwork was completed in Q4 2025. A total of 41 rock samples were collected across the project and results from 13 have been received, while 16 are pending. The majority of the 13 samples are located within the vicinity of the Main Gossan zone (MGZ), where previous work by the company included trenching and grab sampling. A live discussion of the results will be held on Friday, Jan. 9, at 1 p.m. ET.

Highlights

• Assay results at the Main Gossan zone confirm high-grade copper, gold and silver mineralization.
• The Main Gossan zone is associated with regional high magnetic and conductor trends where disruption from structures and hydrothermal alteration has accumulated copper, gold and silver mineralization.
• Five of the 13 grab samples assayed greater than 1 per cent copper, while four of the samples assayed greater than 1.0 g/t gold and four assayed greater than 10 g/t silver.
• Copper, gold and silver mineralization now covering over 1,000 metres by 800 metres at the Main Gossan zone.

Shannon Baird, vice-president of exploration for Cascade Copper, comments: "These initial results from the Q4 field program confirm the outstanding copper, gold and silver mineralization potential at Centrefire. From the geophysical signatures, we can see that the disruption in the magnetic and conductor trends are associated with increased mineralization and likely intense hydrothermal activity. This sampling program and these results show mineralization at the Main Gossan zone for more than one kilometre in strike over a width of almost 800 metres." Mr. Baird adds, "Our ongoing 3-D modelling of the geophysics and surface assay results will help refine our drill targets for an upcoming maiden drill program."

Gold and silver values

The mineralization at Centrefire is associated with banded iron formation (BIF) and volcanogenic massive sulphide (VMS) style mineralization with associated intense hydrothermal activity. This style of mineralization typically includes high values of gold and silver as well as elevated values of other base metals and pathfinder elements. The highly anomalous gold and silver values associated with higher-grade copper but less zinc and lead anomalism suggest a hotter environment within a hydrothermal feeder zone and potential proximity to a high-grade massive sulphide lens. VMS systems are known to form in clusters, greatly increasing the exploration potential of the project. Note that one sample that assayed 1.46 per cent Cu, 0.452 gram per tonne Au and 23.5 g/t Ag also contained 0.23 per cent tungsten.

Next steps -- drill targets, permit approval

These results, in combination with the corporation's previous trenching and sampling and the continuing geophysical inversion modelling exercise will significantly help delineate drill targets for an upcoming program. A drill permit has been submitted and approval is expected within Q1 of 2026. The results from this upcoming drill program will be particularly helpful for interpreting the analogous geology and mineralization potential of the eastern portion of the project where minimal outcrop exposures and a thin sandy till cover throughout makes traditional surface prospecting difficult.

Sample analysis QA/QC (quality assurance/quality control) protocol and disclosure

All rock samples collected were submitted to ALS Canada Ltd. (ALS) at its Sudbury, Ont., facility for preparation and analysis. ALS meets all requirements of International Standards ISO/IEC 17025:2005 and ISO 9001:2015 for analytical procedures. Each sample had a small representative reference sample split out for storage while the remaining bulk was photographed, tagged and bagged for analysis. Samples were analyzed using ALS's 30-gram fire assay fusion method (Au-ICP21) with an ICP-AES finish for gold and by a 34-element four-acid digest ICP-AES analysis (ME-ICP61) with additional analysis for ore grade elements (ME-OG62) and ore grade Cu (Cu-OG62). Results were reported in parts per million (ppm) and converted to per cent, or grams per tonne (g/t) when applicable.

The technical information in this news release was prepared and reviewed by Shannon Baird, PGeo, a qualified person as defined in National Instrument 43-101.

About Cascade Copper Corp.

Cascade Copper is an exploration stage natural resource company engaged in the evaluation, acquisition and exploration of copper-based mineral resource properties. Cascade is focused on copper and gold, porphyry, and mesothermal gold deposits in British Columbia, and VMS and BIF copper, gold and silver style deposits in Ontario. Cascade's priority is to conduct exploration using modern technology that includes 3-D inversion modelling of geophysics, lidar-(light detection and ranging)-derived elevation models and AI enhanced predictive modelling from all historic and modern data inputs. Drilling is planned on several of its copper projects this year. Cascade has five projects, including the Copper Plateau copper-molybdenum project, the Centrefire copper-gold project, the Rogers Creek copper-gold project, Fire Mountain copper-gold project and the Bendor gold-tungsten project.

A live discussion of the results will be held on Friday, Jan. 9, at 1 p.m. ET.
