Star Copper plans 3-D IP survey at Star

Executive Summary

• Star Copper Corp. is deploying an advanced deep-penetrating 3D Induced Polarization (IP) and Magnetotelluric (MT) geophysical survey at its flagship Star project in northwestern British Columbia.
• The survey utilizes Quantec Geoscience’s Orion Swath technology to image subsurface structures to depths of 750–1,500+ meters, aiming to refine the geological model and identify high-impact drill targets.
• Results will directly inform the company’s planned aggressive 2026 drill program, focusing on deep-seated chargeability and resistivity anomalies associated with porphyry copper-gold systems.

Key Details

• Technology Deployed: Advanced deep-penetrating Orion Swath 3-D IP (induced polarization) survey combined with Magnetotelluric (MT) data.
• Service Provider: Quantec Geoscience, a global leader in deep-imaging geophysical solutions.
• Survey Depth Capabilities:
  • DC-IP and MT data provide comprehensive 3D rendering to depths exceeding approximately 750 meters.
  • Deeper resistivity imaging extends to 1,500 meters and beyond.
• Technical Methodology:
  • Simultaneous measurement of resistivity and chargeability using distributed acquisition methods.
  • Integration of naturally occurring electric and magnetic fields (MT) densely sampled across the survey array.
  • Focus on identifying deep-seated chargeability and resistivity anomalies linked to potential intrusive centers and mineralized feeder structures.
• Strategic Objective:
  • Tighten the geophysical model for Calk-alkaline porphyries.
  • Inform drill targeting, hole orientation, and depth selection for the 2026 drill program.
  • Evaluate large-scale geological architecture, including deep intrusive bodies, major structures, and feeder zones critical for porphyry copper-gold systems.
• Precedent/Validation: The CEO cited the Red Chris mine as a case where similar deep-penetrating IP and MT technologies identified deeper high-grade mineralization beneath known deposits.
• Qualified Person: Jeremy Hanson, PGeo, independent contractor, has reviewed and approved the technical aspects under National Instrument 43-101.

Notable Quotes

• "This technology is particularly well suited for porphyry copper exploration in British Columbia, where many deposits extend well below the limits of conventional geophysical methods and early-stage drilling. Notably, deep-penetrating IP and MT technologies developed by Quantec were instrumental in advancing the geological understanding of the Red Chris mine, where deeper high-grade mineralization was identified beneath the known deposit, demonstrating the importance of imaging the full vertical extent of porphyry systems." — Darryl Jones, CEO
