Cascade Copper Announces Exceptional Results from VTEM Modelling at the Centrefire Copper-Gold Project, Finalizes Drillhole Selection

About this update from Cascade Copper Corp.

Vancouver, British Columbia - Cascade Copper Corp. (CSE: CASC, FRA: 91O) ('Cascade' or the 'Corporation') is pleased to announce that it has received Electro-Magnetic (EM) Plate Modelling results from the historic VTEM airborne survey performed by Geotech Ltd in 2010. The plate modelling was created and interpreted by Mira Geoscience which uses advanced analytical techniques to produce the 3D inversions. The results indicate multiple highly prospective Volcanogenic Massive Sulphide (VMS) targets at and near the Main Gossan Zone ('MGZ') at its Centrefire Copper and Gold Project (the 'Project') located 40 kilometres northeast of Dryden, Ontario, Canada . Highlights Two classic high-conviction VMS targets within the MGZ identified by high conductivity associated with high magnetic response. Additional compelling VMS targets along strike of the MGZ with similar coincident signatures to the MGZ; now being referred to as the Southwest Zone , or SWZ. Potential Banded Iron Formation (BIF) gold targets separate from the VMS targets. Jeff Ackert , President and CEO for Cascade Copper comments 'The exercise of modelling the VTEM data at Centrefire prior to drilling has created some exceptional VMS targets in and around the MGZ. On the ground we've observed highly mineralized and highly altered volcanic rock. Sampling of trenches and outcrops has returned multi-percent copper values, multi-gram gold and silver values - now backed up with several sub surface geophysical expressions of VMS mineralization. We feel that the targets are well vetted and de-risked to give us the best chance of a significant discovery. Our upcoming drilling will verify the model - with additional upside within the Centerfire claims along the highly prospective 8km strike length.' The historic drilling at Centrefire ( Phelps Dodge 1968) targets surface mineralization which is interpreted to be the feeder zone for the more laterally extensive and more mineralized VMS horizon at depth. The mineralized system is interpreted to be folded and overturned resulting in the ancient VMS lens horizons expected position occurring further below the current surface. The highly conductive and flat lying plate models confirm this interpretation, as they represent the tops of the most conductive material. These flat lying, highly conductive plates are also associated with high magnetic signatures typical of the metamorphism from pyrite to magnetic pyrrhotite in the lens. This combination of high conductance and high magnetic signature represent a typical Archean age VMS system. Next Steps - Drill Contract It is anticipated that with the extremely compelling VMS targets afforded by the VTEM modelling that a drill contract will be negotiated and signed in the very near future. This will lead to a drilling program at Centrefire within the next month. About Cascade Copper 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 3D inversion modelling of geophysics, LiDAR structural analysis, and AI enhanced predictive modelling from all historic and modern data inputs. Cascade has five projects, including the Copper Plateau Copper-Moly Project , the Centrefire Copper-Gold Project , the Rogers Creek Copper-Gold Project , Fire Mountain Copper-Gold Project , and the Bendor Gold-Tungsten Project .
