Vancouver, British Columbia — February 26, 2026 — Leads & Copy — Cascade Copper Corp. (CSE: CASC) has completed a 3D magnetic inversion of the airborne magnetic-radiometric survey on its Bendor Gold-Tungsten Project, located about 15 kilometers northeast of the Bralorne Gold Mine near Gold Bridge, British Columbia, Canada.
The 3D magnetic inversion delineates a large interconnected intrusive body with numerous cupolas stretching toward the surface beneath known gold-bearing mineralized zones and gold-in-soil anomalies.
These cupolas likely represent multiple “blind” intrusions of the Bendor Intrusive Suite, which is mapped on the Project and known in the area as being closely linked in timing and space to gold-bearing systems. The project is located proximal to Talisker Resources’ Bralorne Mine and Endurance Gold’s Reliance Project.
Historical samples from underground workings at Bristol assayed up to 30.86 g/t Au and 6.5 % WO. Widespread untested gold-in-soil anomalies are present across the Project.
The next steps involve integrating the magnetic inversion into a cohesive 3D geological model of the mineralizing environment, including historic mine workings and underground drilling, to aid future exploration and drill targeting. The company plans to submit diamond drilling and geophysics permit applications soon after completing the Project-wide 3D compilation and geological data modeling.
Expanded Project-wide soil sampling with modern multi-element analysis for pathfinder target generation, along with detailed mapping and sampling of known mineralized zones and gold-in-soil anomalies, are also planned. These efforts could potentially lead to diamond drilling targets in 2026.
Cascade Copper believes that the gold and tungsten mineralization reported from the historic Bristol Mine workings and adjacent mineralized vein systems could be linked to the magnetic cupolas and their related hydrothermal systems and may continue along strike and to depth. Historical samples from underground workings at Bristol reportedly assayed up to 30.86 g/t gold and 6.5 % tungsten trioxide (WO3), and a 23kg sample taken from a winze reportedly assayed 48 g/t Au, 20.6 g/t Ag, and 0.16 % WO3.
Shannon Baird, VP Exploration for Cascade Copper, said that previous exploration work at Bendor has shown some impressive values of gold, tungsten, and silver throughout the Bristol and Benboe workings and vein systems. The company is excited that the 3D magnetic inversion modelling has verified the potential interconnected nature of all these showings and looks forward to following up on these newly generated targets. Baird added that there exists significant potential to expand on the mineralized gold system at Bendor.
The Bendor Project has only had minimal surface exploration work in the past and has only been shallowly drilled within a narrow region surrounding the historic mine workings at Bristol. For more details, the previous news release dated November 20, 2025, details the historical results at Bendor.
The airborne magnetics-radiometrics survey shows a strong correlation with geology and mineralization with high magnetic intensity in the south and central portion of the Project where the various Bendor intrusives likely created a hornfelsing of the local lithologies. There also exists a strong correlation of lower or disrupted magnetic intensity to structural complexity and offsets where hydrothermal fluids tend to focus. The highly magnetic central portion of the project is interpreted to be a zone of hornfelsing and hydrothermal alteration with potential magnetite, gold, tungsten, silver, and copper enrichment. The majority of the historic gold-in-soils and surface sampling with high gold values have been associated with this highly underexplored magnetic halo zone.
In partially glaciated terrains like Bendor, geophysics such as EM and magnetics play a crucial role in discovery. Inversion of the magnetics data allows modeling and projecting subsurface magnetism, revealing large scale and localized zones of magnetic anomalism potentially caused by hydrothermal alteration and mineralizing fluids. The Bendor Project has several “clustered” target zones of intense magnetics probably outlining the presence of cupolas stemming from an underlying Bendor intrusive. This inversion exercise has clearly identified the known outcropping Bendor intrusive and related hydrothermal alteration and mineralization, and it has outlined several other large analogous zones of high interest clustered within an ~10km2 zone on either side of the Tommy Creek Fault and historical Bristol Mine workings.
A more detailed surficial 2D gridding and a subsurface 3D magnetic inversion model has been completed on the airborne magnetic-radiometric data flown over the entirety of the Project. This was done to test the theory that the clustered circular magnetic features observed in the surficial data are connected to a larger subsurface body of the Bendor Intrusive Suite known to be associated with gold mineralization in the region. The Corporation felt this was a necessary exercise to perform since magnetics appears to correlate well with known geology and mineralization, and we feel this will significantly assist in subsurface structural and the on-going geological modelling and delineate potential zones of alteration and mineralization to target in future drilling campaigns.
Initial review of the inversion model has verified the theory of a potential mineralizing intrusive interconnected at depth and related to the known surficial gold mineralization. There is only one larger known outcropping of the Bendor pluton which correlated exactly with the larger circular magnetics feature in the centre of the Project. The other magnetic cupola target zones are buried under thin cover and don’t outcrop at surface but their magnetic influence is definitely seen in the surface data.
The large central 2-D magnetics feature is actually a mag-low surrounded by a ring of high magnetics which the Corporation interprets to be a hornfelsing and alteration of country rock by the intrusive and its hydrothermal fluids. However, other magnetic anomalies are near solid magnetic high features, which could be explained by depths of the intrusion emplacement and erosional levels.
The Tommy Creek Fault and Shear Zone, which hosts the Bristol Mine workings and the Benboe vein, emerges from the inversion modelling as an area of magnetic erosion. The magnetic response in this area has been diminished. It is interpreted that the structures along the trend have carried fluid that have destroyed the magnetic component of the Bendor Intrusive. It is possible that the Tommy Creek Fault and Shear has succumbed to multiple episodes of deformation and fluid flow which has resulted in the gold and tungsten bearing veins found at the Bristol Mine.
The distinctive weathered slope located south of the Bristol 11 Prospect hints at strong sericite clay alteration. The alteration zone is adjacent to the large gold in soil anomaly at the Bristol 11 prospect and is within a magnetic low area between two magnetic intrusive bodies. It is noted that soil sampling has not covered this distinctive alteration zone and will be a top priority in the next field program. The alteration zone fits with the theory of a hornfelsing and mineralization event associated with the contacts of the intrusives. It is also noted that there may be a structure associated with the alteration trend that mimics the directions of the neighbouring Bralorne- Pioneer mine and Reliance inferred resource.
The Oxide Ridge Prospect is a newly discovered area with only a few traverses across the eastern flank of the ridge done by Cascade’s team during acquisition due diligence. The presence of sulphide veining and copper oxide staining as well as highly anomalous grab samples indicates an intriguing area for future follow up work.
Completion of the 3D magnetic inversion, along with an overview compilation and review of all historical mining, sampling, and drilling data in combination with the recent airborne magnetics and LiDAR survey data, have revealed several targets worthy of “near-term” follow-up in the field. Subsurface geological modelling is expected to generate additional high-priority targets in preparation for drill permitting and diamond drilling.
The detailed magnetic inversion modelling exercise indicates a strong correlation of anomalous to high grade gold, silver, tungsten, and copper to high magnetics with mineralizing intrusive contacts and low magnetic disruptions associated with structural features focusing hydrothermal fluids that carry the gold. The Corporation believes that performing additional detailed and refined 3D geological modelling of all historical maps and data along with mining and assay data will significantly help further delineate priority drill targets. The Corporation also plans to submit a diamond drilling and geophysics permit application shortly following completion of the Project-wide compilation of historic data and geological 3D modelling. Additionally, newly verified surface magnetic and gold-in-soil anomalies will be ground-truthed early in the next field season.

Management cautions that historical results are unverified and that grab samples are selective in nature, and the assay results may not necessarily represent true underlying mineralization.
