CASCADE COPPER ANNOUNCES ADDITIONAL RESULTS FROM FIELD WORK AT THE CENTREFIRE COPPER-GOLD PROJECT

Cascade Copper Corp. has received assay results from the second 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. This batch represents 16 of 41 rock samples that were collected across the project. The results of the first batch of 13 samples were released on Jan. 6, 2026, and included up to 2.86 per cent copper, 2.84 grams per tonne gold and 29.40 grams per tonne silver in grab samples. The corporation is also pleased to announce that continuing magnetic inversion modelling and compilation are revealing excellent priority target follow-up areas for mapping, sampling and possibly drilling.

Highlights:

• Additional assay results from the Main Gossan zone (MGZ) and western section of the project area confirm copper, gold and silver mineralization across 10 kilometres of strike.
• Magnetic inversion modelling indicates disrupted magnetic trends, near surface and more importantly at depth, in multiple areas, similar to the Main Gossan zone.
• The majority of the magnetic and conductor trends are covered with sandy till limiting outcrop exposure, which indicates the need for additional exploration outside of the MGZ.

Jeff Ackert, president and chief executive officer for Cascade Copper, commented: "The additional sample results from Centrefire show that mineralization is evident along the trend from the MGZ in the southwest to the extent of the project area to the northeast. The MGZ is the obvious target for drilling this year, but we are confident that there may be other similar copper, gold and silver mineralized zones beneath the glacial till and sand along this trend." Mr. Ackert added: "The 3-D modelling of the magnetics is showing some similar attributes as the MGZ along this trend, which we will follow up with soil sampling and geophysics to better define these areas."

Copper, gold and silver values

The second batch of samples from the 2025 field program confirmed strong copper, gold and silver mineralization within the MGZ, with grab sample CFRX028 returning 1.80 per cent copper from a highly mineralized and altered mafic pillow basalt. Sample CFRX036 returned 0.93 per cent copper from a similar-looking mineralized and altered pillow basalt that also had an extremely anomalous gold value of 0.776 gram per tonne gold. CFRX036 is located near the western exposure of the MGZ and approximately 450 metres from sample CFRX028. Of significance is the sample CFRX002 taken near the eastern limit of the project area that returned 813 parts per million copper (0.08 per cent copper), which indicates copper mineralization within the lithological package over 9.0 kilometres along strike from the MGZ.

The mineralization at Centrefire is associated with BIF- (banded iron formation) and VMS-style (volcanogenic massive sulphide) mineralization with associated intense hydrothermal activity. This style of mineralization typically includes not only high-grade copper but also high values of gold and silver and 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 high-grade massive sulphide lenses. VMS systems are known to form in clusters, greatly increasing the exploration potential of the project. Note that one sample (CFRX018) assayed 0.11 per cent tungsten. The presence of tungsten in samples at Centrefire is not typical of primary VMS deposits, but it may indicate the presence of the disruptive hydrothermal fluids that are affecting the magnetic signatures.

Inversion modelling of airborne magnetic data

After analyzing and inverting the historical magnetic coverage over the high-grade Main Gossan zone, a strong correlation between magnetic disruption, VTEM (versatile time-domain electromagnetic) anomalies, hydrothermal alteration, and copper/gold/silver mineralized rocks emerged. In glaciated terrains such as Centrefire with thin sandy till coverage and very minimal outcrop exposures, geophysics such as EM (electromagnetic) and magnetics play a crucial role in discovery. A drone magnetics survey was flown to cover the eastern portion of the project, which will be followed up with a complementary VTEM survey.

Merging of the historical airborne magnetics survey with the newly acquired high-resolution drone magnetics survey followed by an unconstrained 3-D magnetic inversion on the full data set was the next logical step. The inversion allows the company to model and project subsurface magnetism and see large-scale and localized zones of magnetic disruption that could be caused by hydrothermal alteration and potentially mineralizing fluids. The Centrefire project has several stacked parallel zones of intense magnetics probably tracing banded iron formation, which, when infiltrated by hot mineralizing fluids, creates a very distinctive break in the magnetic signal that can help the company zero in on the most prospective target zones to follow up on. This inversion exercise has done just that. Besides clearly identifying the high-grade MGZ within a broader zone of hydrothermal alteration and mineralization, it has outlined several large analogous zones of high interest up to 10 kilometres along strike of the MGZ, some of which have already shown promising elevated copper results from the Batch 2 sampling.

Next steps -- drill targets, permit approval

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

Sample analysis quality assurance/quality control protocol and disclosure

All rock samples collected were submitted to ALS Canada Ltd. 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 analyses for ore-grade elements (ME-OG62) and ore-grade copper (Cu-OG62). Results were reported in parts per million and converted to per cent or grams per tonne when applicable.
