CASCADE COPPER RECEIVES DRILL PERMIT APPROVAL FOR THE CENTREFIRE COPPER-GOLD PROJECT

Cascade Copper Corp. has received approval for its maiden drilling program at its Centrefire copper and gold project, located approximately 40 kilometres northeast of Dryden, Ont., Canada.

Jeffrey Ackert, president and chief executive officer of Cascade Copper, comments: "Cascade's team has done their homework and we are now ready for our first drill program at Centrefire. The compilation of historic work, plus the surface trenching, rock sampling, new high-resolution airborne magnetics and the 3-D inversion modelling, has given us not only some compelling targets but high confidence in the geological model. We expect to be drilling in Q2 this year. Please view our video for more information on the Centrefire drilling."

Cascade has developed its geological model for this volcanogenic massive sulphide (VMS) style of deposit through a compilation of historic data, from new surface sampling collected by trenching and rock sampling that verifies the historic work, and by flying high-resolution drone-based magnetics. Subsequent modelling in 3-D and inverting the magnetic data has produced several target zones for copper, gold and silver mineralization.

Drilling will focus on the high-grade main gossan zone (MGZ) located in the southwestern portion of the project area. Trenching and grab sampling have returned values up to 2.85 per cent copper (Cu), 2.84 grams per tonne (g/t) gold (Au) and 29.4 g/t silver (Ag) from rusty volcanics and pillowed flows. It is interpreted that the VMS system has been overturned and the feeder zones will have a relatively small footprint close to surface with larger and laterally extensive lenses at depth. The planned drill program will intersect the interpreted MGZ feeder near surface and test for massive sulphide lenses with a number of deeper holes.

Within the package of rocks at Centrefire and in close proximity to the MGZ lie several highly magnetic banded iron formations (BIF). These formations act as marker units across the full 10 kilometres of strike length within the property. There is a relationship observed between the disrupted magnetic signature of the BIF and high-grade mineralization at the MGZ. At least five other areas of disrupted magnetic signatures are noted across the project and create additional feeder zone type targets to follow up with ground truthing and future drilling. The BIF units in this case may also act as a typical Archean-aged gold mineralization host, perhaps similar to the Pickle-Crow gold mine in Ontario (1.23 million ounces (oz) at 4.1 g/t Au inferred).

Cascade Copper plans to drill up to 1,000 metres (m) in four or five holes at Centrefire that will test the MGZ and BIF targets. Drilling is planned to start in Q2 (second quarter) 2026.

Cascade Copper is also pleased to announce that it has received one of 68 Ontario junior exploration program (OJEP) grants that has reimbursed 50 per cent of its 2025 exploration costs at Centrefire.

Shannon Baird, vice-president of exploration for Cascade Copper, explains: "The OJEP grant is a welcome addition to our project funding at Centrefire. We acknowledge the government of Ontario's contribution to exploration and in particular to our Centrefire copper project. Sampling and mapping at Centrefire has been completed, and has contributed to our understanding of the Centrefire VMS and BIF mineralizing systems."

"Ontario is leading the charge to secure the minerals that will power our economy and strengthen our sovereignty," said Stephen Lecce, Minister of Energy and Mines. "Through OJEP, we're backing companies like Cascade Copper Corp. to advance promising projects here at home-unlocking resources, creating jobs, and building a more self-reliant and secure Canadian economy."

Next steps

The corporation will continue exploration at Centrefire after the Q2 2026 diamond drill program to evaluate the along strike continuity of the copper and gold mineralization, especially where the magnetic disruptions are noted. A gridded geochemical sampling program is planned and, if positive, an additional EM (electromagnetic) survey to the east will confirm subsurface mineralization.

Cascade Copper has prepared a 10-minute video to discuss the importance of the permit issuance and to discuss the compelling drill targets at Centrefire.

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) elevation models, and AI-enhanced (artificial intelligence) predictive modelling from all historic and modern data inputs. Drilling is planned on several of its copper-gold targets this year. Cascade has five projects, including the Copper Plateau copper-moly project, the Centrefire copper-gold project, the Rogers Creek copper-gold project, the Fire Mountain copper-gold project and the Bendor gold-tungsten project.
