Cascade Copper conducts magnetic inversion of survey

Executive Summary

• Cascade Copper Corp. has completed a 3-D magnetic inversion of airborne magnetic-radiometric survey data on its Bendor gold-tungsten project in British Columbia, identifying a large, interconnected intrusive body with numerous blind "cupolas" beneath known mineralized zones.
• The geophysical modeling suggests that historical high-grade gold and tungsten mineralization (from the Bristol mine workings) is linked to these subsurface intrusions and hydrothermal systems, which may extend along strike and to depth.
• The company plans to integrate this data into a 3-D geological model to generate drill targets, with plans to submit diamond drilling and geophysics permit applications in the near future, potentially leading to drilling in 2026.

Key Details

• Geophysical Findings: 3-D magnetic inversion delineated a large interconnected intrusive body with numerous cupulas stretching toward the surface beneath known gold-bearing zones and gold-in-soil anomalies.
• Geological Interpretation: Cupolas likely represent multiple blind intrusions of the Bendor intrusive suite, which are known in the region to be closely linked in timing and space to gold-bearing systems.
• Historical Assay Data:
  • Historical samples from underground workings at Bristol assayed up to 30.86 g/t gold (Au) and 6.5% WO3.
  • A 23-kg sample from a winze assayed 48 g/t Au, 20.6 g/t silver (Ag), and 0.16% WO3.
• Survey Correlation: Airborne magnetics-radiometrics showed strong correlation with geology, with high magnetic intensity in the south and central portions indicating hornfelsing and potential magnetite, gold, tungsten, silver, and copper enrichment.
• Target Zones:
  • Several clustered target zones of intense magnetics outline potential cupolas stemming from an underlying Bendor intrusive within an approximately 10 square km zone on either side of the Tommy Creek fault and historical Bristol mine workings.
  • The central 2-D magnetics feature is interpreted as a magnetic-low surrounded by a ring of high magnetics (hornfelsing/alteration), while other anomalies are solid magnetic-high features.
  • The Tommy Creek fault and shear zone emerged as an area of magnetic erosion, interpreted as structures that carried fluids destroying the magnetic component of the intrusive, hosting the gold-and-tungsten-bearing veins.
  • A distinctive weathered slope south of the Bristol 11 prospect shows strong sericite clay alteration, adjacent to a large gold-in-soil anomaly and within a magnetic-low area between two magnetic intrusive bodies.
  • Oxide Ridge: A newly discovered area with sulphide veining, copper oxide staining, and highly anomalous grab samples identified as intriguing for future follow-up.
• Next Steps:
  • Integration of magnetic inversion into a cohesive 3-D geological model including historical mine workings and drilling.
  • Submission of diamond drilling and geophysics permit applications in the near future.
  • Expanded project-wide soil sampling with modern multielement analysis.
  • Detailed mapping and sampling of known mineralized zones.
  • Potential for diamond drilling targets in 2026.
• Project Location: Located approximately 15 km northeast of the operating Bralorne gold mine (Talisker Resources) and near Endurance Gold's Reliance project, near Gold Bridge, B.C., Canada.

Notable Quotes

• Shannon Baird, Vice-President of Exploration: "The previous exploration work at Bendor has shown some impressive values of gold, tungsten and silver throughout the Bristol and Benboe workings and vein systems. We are extremely excited that the 3-D magnetic inversion modelling has verified the potential interconnected nature of all these showings, and we are excited to get on the ground and follow up on these newly generated targets. By all indications, there exists significant potential to expand on the mineralized gold system at Bendor."
